+
+Garage has many API that you can rely on to build complex applications.
+In this section, we reference the existing SDKs and give some code examples.
+
+
+## ⚠️ DISCLAIMER
+
+**K2V AND ADMIN SDK ARE TECHNICAL PREVIEWS**. The following limitations apply:
+  - The API is not complete, some actions are possible only through the `garage` binary
+  - The underlying admin API is not yet stable nor complete, it can breaks at any time
+  - The generator configuration is currently tweaked, the library might break at any time due to a generator change
+  - Because the API and the library are not stable, none of them are published in a package manager (npm, pypi, etc.)
+  - This code has not been extensively tested, some things might not work (please report!)
+
+To have the best experience possible, please consider:
+  - Make sure that the version of the library you are using is pinned (`go.sum`, `package-lock.json`, `requirements.txt`).
+  - Before upgrading your Garage cluster, make sure that you can find a version of this SDK that works with your targeted version and that you are able to update your own code to work with this new version of the library.
+  - Join our Matrix channel at `#garage:deuxfleurs.fr`, say that you are interested by this SDK, and report any friction.
+  - If stability is critical, mirror this repository on your own infrastructure, regenerate the SDKs and upgrade them at your own pace.
+
+
+## About the APIs
+
+Code can interact with Garage through 3 different APIs: S3, K2V, and Admin.
+Each of them has a specific scope.
+
+### S3
+
+De-facto standard, introduced by Amazon, designed to store blobs of data.
+
+### K2V
+
+A simple database API similar to RiakKV or DynamoDB.
+Think a key value store with some additional operations.
+Its design is inspired by Distributed Hash Tables (DHT).
+
+More information:
+  - [In the reference manual](@/documentation/reference-manual/k2v.md)
+
+
+### Administration
+
+Garage operations can also be automated through a REST API.
+We are currently building this SDK for [Python](@/documentation/build/python.md#admin-api), [Javascript](@/documentation/build/javascript.md#administration) and [Golang](@/documentation/build/golang.md#administration).
+

+```
+# List buckets
+print(client.list_buckets())
+
+# Put an object containing 'content' to /path in bucket named 'bucket':
+content = b"content"
+client.put_object(

+
+```python
+import garage_admin_sdk
+from garage_admin_sdk.apis import *
+from garage_admin_sdk.models import *
+
+configuration = garage_admin_sdk.Configuration(
+  host = "http://localhost:3903/v0",
+  access_token = "s3cr3t"
+)
+
+# Init APIs
+api = garage_admin_sdk.ApiClient(configuration)
+nodes, layout, keys, buckets = NodesApi(api), LayoutApi(api), KeyApi(api), BucketApi(api)
+
+# Display some info on the node
+status = nodes.get_nodes()
+print(f"running garage {status.garage_version}, node_id {status.node}")
+
+# Change layout of this node
+current = layout.get_layout()
+layout.add_layout({
+  status.node: NodeClusterInfo(
+    zone = "dc1",
+    capacity = 1,
+    tags = [ "dev" ],
+  )
+})
+layout.apply_layout(LayoutVersion(
+  version = current.version + 1
+))
+
+# Create key, allow it to create buckets
+kinfo = keys.add_key(AddKeyRequest(name="openapi"))
+
+allow_create = UpdateKeyRequestAllow(create_bucket=True)
+keys.update_key(kinfo.access_key_id, UpdateKeyRequest(allow=allow_create))
+
+# Create a bucket, allow key, set quotas
+binfo = buckets.create_bucket(CreateBucketRequest(global_alias="documentation"))
+binfo = buckets.allow_bucket_key(AllowBucketKeyRequest(
+  bucket_id=binfo.id,
+  access_key_id=kinfo.access_key_id,
+  permissions=AllowBucketKeyRequestPermissions(read=True, write=True, owner=True),
+))
+binfo = buckets.update_bucket(binfo.id, UpdateBucketRequest(
+  quotas=UpdateBucketRequestQuotas(max_size=19029801,max_objects=1500)))
+
+# Display key
+print(f"""
+cluster ready
+key id is {kinfo.access_key_id}
+secret key is {kinfo.secret_access_key}

+Garage exposes some internal metrics in the Prometheus data format.
+This page explains how to exploit these metrics.
+
+## Setting up monitoring
+
+### Enabling the Admin API endpoint
+
+If you have not already enabled the [administration API endpoint](@/documentation/reference-manual/admin-api.md), do so by adding the following lines to your configuration file:
+
+```toml
+[admin]
+api_bind_addr = "0.0.0.0:3903"
+```
+
+This will allow anyone to scrape Prometheus metrics by fetching
+`http://localhost:3093/metrics`. If you want to restrict access
+to the exported metrics, set the `metrics_token` configuration value
+to a bearer token to be used when fetching the metrics endpoint.
+
+### Setting up Prometheus and Grafana
+
+Add a scrape config to your Prometheus daemon to scrape metrics from
+all of your nodes:
+
+```yaml
+scrape_configs:
+  - job_name: 'garage'
+    static_configs:
+      - targets:
+        - 'node1.mycluster:3903'
+        - 'node2.mycluster:3903'
+        - 'node3.mycluster:3903'
+```
+
+If you have set a metrics token in your Garage configuration file,
+add the following lines in your Prometheus scrape config:
+
+```yaml
+    authorization:
+      type: Bearer
+      credentials: 'your metrics token'
+```
+
+To visualize the scraped data in Grafana,
+you can either import our [Grafana dashboard for Garage](https://git.deuxfleurs.fr/Deuxfleurs/garage/raw/branch/main/script/telemetry/grafana-garage-dashboard-prometheus.json)
+or make your own.
+We detail below the list of exposed metrics and their meaning.
+
+
+
+## List of exported metrics
+
+
+### Metrics of the API endpoints
+
+#### `api_admin_request_counter` (counter)
+
+Counts the number of requests to a given endpoint of the administration API. Example:
+
+```
+api_admin_request_counter{api_endpoint="Metrics"} 127041
+```
+
+#### `api_admin_request_duration` (histogram)
+
+Evaluates the duration of API calls to the various administration API endpoint. Example:
+
+```
+api_admin_request_duration_bucket{api_endpoint="Metrics",le="0.5"} 127041
+api_admin_request_duration_sum{api_endpoint="Metrics"} 605.250344830999
+api_admin_request_duration_count{api_endpoint="Metrics"} 127041
+```
+
+#### `api_s3_request_counter` (counter)
+
+Counts the number of requests to a given endpoint of the S3 API. Example:
+
+```
+api_s3_request_counter{api_endpoint="CreateMultipartUpload"} 1
+```
+
+#### `api_s3_error_counter` (counter)
+
+Counts the number of requests to a given endpoint of the S3 API that returned an error. Example:
+
+```
+api_s3_error_counter{api_endpoint="GetObject",status_code="404"} 39
+```
+
+#### `api_s3_request_duration` (histogram)
+
+Evaluates the duration of API calls to the various S3 API endpoints. Example:
+
+```
+api_s3_request_duration_bucket{api_endpoint="CreateMultipartUpload",le="0.5"} 1
+api_s3_request_duration_sum{api_endpoint="CreateMultipartUpload"} 0.046340762
+api_s3_request_duration_count{api_endpoint="CreateMultipartUpload"} 1
+```
+
+#### `api_k2v_request_counter` (counter), `api_k2v_error_counter` (counter), `api_k2v_error_duration` (histogram)
+
+Same as for S3, for the K2V API.
+
+
+### Metrics of the Web endpoint
+
+
+#### `web_request_counter` (counter)
+
+Number of requests to the web endpoint
+
+```
+web_request_counter{method="GET"} 80
+```
+
+#### `web_request_duration` (histogram)
+
+Duration of requests to the web endpoint
+
+```
+web_request_duration_bucket{method="GET",le="0.5"} 80
+web_request_duration_sum{method="GET"} 1.0528433229999998
+web_request_duration_count{method="GET"} 80

 For instance, here, the Mercury node could be moved to Brussels; this would allow the cluster

+### Best practices
+
+- If you have fast dedicated networking between all your nodes, and are planing to store
+  very large files, bump the `block_size` configuration parameter to 10 MB
+  (`block_size = 10485760`).
+
+- Garage stores its files in two locations: it uses a metadata directory to store frequently-accessed
+  small metadata items, and a data directory to store data blocks of uploaded objects.
+  Ideally, the metadata directory would be stored on an SSD (smaller but faster),
+  and the data directory would be stored on an HDD (larger but slower).
+
+- For the data directory, Garage already does checksumming and integrity verification,
+  so there is no need to use a filesystem such as BTRFS or ZFS that does it.
+  We recommend using XFS for the data partition, as it has the best performance.
+  EXT4 is not recommended as it has more strict limitations on the number of inodes,
+  which might cause issues with Garage when large numbers of objects are stored.
+
+- If you only have an HDD and no SSD, it's fine to put your metadata alongside the data
+  on the same drive. Having lots of RAM for your kernel to cache the metadata will
+  help a lot with performance.  Make sure to use the LMDB database engine,
+  instead of Sled, which suffers from quite bad performance degradation on HDDs.
+  Sled is still the default for legacy reasons, but is not recommended anymore.
+
+- For the metadata storage, Garage does not do checksumming and integrity
+  verification on its own. If you are afraid of bitrot/data corruption,
+  put your metadata directory on a BTRFS partition. Otherwise, just use regular
+  EXT4 or XFS.
+
+- Having a single server with several storage drives is currently not very well
+  supported in Garage ([#218](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/218)).
+  For an easy setup, just put all your drives in a RAID0 or a ZFS RAIDZ array.
+  If you're adventurous, you can try to format each of your disk as
+  a separate XFS partition, and then run one `garage` daemon per disk drive,
+  or use something like [`mergerfs`](https://github.com/trapexit/mergerfs) to merge
+  all your disks in a single union filesystem that spreads load over them.

 ## Uploading and downlading from Garage
 
-We recommend the use of MinIO Client to interact with Garage files (`mc`).
-Instructions to install it and use it are provided on the
-[MinIO website](https://docs.min.io/docs/minio-client-quickstart-guide.html).
-Before reading the following, you need a working `mc` command on your path.
+To download and upload files on garage, we can use a third-party tool named `awscli`.
 
-Note that on certain Linux distributions such as Arch Linux, the Minio client binary
-is called `mcli` instead of `mc` (to avoid name clashes with the Midnight Commander).
 
-### Configure `mc`
+### Install and configure `awscli`
 
-You need your access key and secret key created above.
-We will assume you are invoking `mc` on the same machine as the Garage server,
-your S3 API endpoint is therefore `http://127.0.0.1:3900`.
-For this whole configuration, you must set an alias name: we chose `my-garage`, that you will used for all commands.
-
-Adapt the following command accordingly and run it:
+If you have python on your system, you can install it with:
 
 ```bash
-mc alias set \
-  my-garage \
-  http://127.0.0.1:3900 \
-  <access key> \
-  <secret key> \
-  --api S3v4
+python -m pip install --user awscli
 ```
 
-### Use `mc`
-
-You can not list buckets from `mc` currently.
-
-But the following commands and many more should work:
+Now that `awscli` is installed, you must configure it to talk to your Garage instance,
+with your key. There are multiple ways to do that, the simplest one is to create a file
+named `~/.awsrc` with this content:
 
 ```bash
-mc cp image.png my-garage/nextcloud-bucket
-mc cp my-garage/nextcloud-bucket/image.png .
-mc ls my-garage/nextcloud-bucket
-mc mirror localdir/ my-garage/another-bucket
+export AWS_ACCESS_KEY_ID=xxxx      # put your Key ID here
+export AWS_SECRET_ACCESS_KEY=xxxx  # put your Secret key here
+export AWS_DEFAULT_REGION='garage'
+export AWS_ENDPOINT='http://localhost:3900'
+
+function aws { command aws --endpoint-url $AWS_ENDPOINT $@ ; }
+aws --version
 ```
 
+Now, each time you want to use `awscli` on this target, run:
+
+```bash
+source ~/.awsrc
+```
+
+*You can create multiple files with different names if you 
+have multiple Garage clusters or different keys.
+Switching from one cluster to another is as simple as
+sourcing the right file.*
+
+### Example usage of `awscli`
+
+```bash
+# list buckets
+aws s3 ls
+
+# list objects of a bucket
+aws s3 ls s3://my_files
+
+# copy from your filesystem to garage
+aws s3 cp /proc/cpuinfo s3://my_files/cpuinfo.txt
+
+# copy from garage to your filesystem
+aws s3 cp s3/my_files/cpuinfo.txt /tmp/cpuinfo.txt
+```
+
+Note that you can use `awscli` for more advanced operations like
+creating a bucket, pre-signing a request or managing your website.
+[Read the full documentation to know more](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3/index.html).
+
+Some features are however not implemented like ACL or policy.

-
-#### UpdateClusterLayout `POST /v0/layout`
-
-Send modifications to the cluster layout. These modifications will
-be included in the staged role changes, visible in subsequent calls
-of `GetClusterLayout`. Once the set of staged changes is satisfactory,
-the user may call `ApplyClusterLayout` to apply the changed changes,
-or `Revert ClusterLayout` to clear all of the staged changes in
-the layout.
-
-Request body format:
-
-```json
-{
-  <node_id>: {
-    "capacity": <new_capacity>,
-    "zone": <new_zone>,
-    "tags": [
-      <new_tag>,
-      ...
-    ]
-  },
-  <node_id_to_remove>: null,
-  ...
-}
-```
-
-Contrary to the CLI that may update only a subset of the fields
-`capacity`, `zone` and `tags`, when calling this API all of these
-values must be specified.
-
-
-#### ApplyClusterLayout `POST /v0/layout/apply`
-
-Applies to the cluster the layout changes currently registered as
-staged layout changes.
-
-Request body format:
-
-```json
-{
-  "version": 13
-}
-```
-
-Similarly to the CLI, the body must include the version of the new layout
-that will be created, which MUST be 1 + the value of the currently
-existing layout in the cluster.
-
-#### RevertClusterLayout `POST /v0/layout/revert`
-
-Clears all of the staged layout changes.
-
-Request body format:
-
-```json
-{
-  "version": 13
-}
-```
-
-Reverting the staged changes is done by incrementing the version number
-and clearing the contents of the staged change list.
-Similarly to the CLI, the body must include the incremented
-version number, which MUST be 1 + the value of the currently
-existing layout in the cluster.
-

-error message is displayed when errors happen. Conversely, if `enabled` is
-`false`, neither `indexDocument` nor `errorDocument` must be specified.
-
-In `quotas`: new values of `maxSize` and `maxObjects` must both be specified, or set to `null`
-to remove the quotas. An absent value will be considered the same as a `null`. It is not possible

+## Testing Garage
+
+Currently, we have the following tests:
+
+- some unit tests spread around the codebase
+- integration tests written in Rust (`src/garage/test`) to check that Garage operations perform correctly
+- integration test for compatibility with external tools (`script/test-smoke.sh`)
+
+We have also tried `minio/mint` but it fails a lot and for now we haven't gotten a lot from it.
+
+In the future:
+
+1. We'd like to have a systematic way of testing with `minio/mint`,
+   it would add value to Garage by providing a compatibility score and reference that can be trusted.
+2. We'd also like to do testing with Jepsen in some way.
+
+## How to instrument Garagae
+
+We should try to test in least invasive ways, i.e. minimize the impact of the testing framework on Garage's source code. This means for example:
+
+- Not abstracting IO/nondeterminism in the source code
+- Not making `garage` a shared library (launch using `execve`, it's perfectly fine)
+
+Instead, we should focus on building a clean outer interface for the `garage` binary,
+for example loading configuration using environnement variables instead of the configuration file if that's helpfull for writing the tests.
+
+There are two reasons for this:
+
+- Keep the soure code clean and focused
+- Test something that is as close as possible as the true garage that will actually be running
+
+Reminder: rules of simplicity, concerning changes to Garage's source code.
+Always question what we are doing.
+Never do anything just because it looks nice or because we "think" it might be usefull at some later point but without knowing precisely why/when.
+Only do things that make perfect sense in the context of what we currently know.
+

+Testing is a research field on its own.
+About testing distributed systems:
+
+ - [Jepsen](https://jepsen.io/) is a testing framework designed to test distributed systems. It can mock some part of the system like the time and the network.

+
+The Garage administration API is accessible through a dedicated server whose
+listen address is specified in the `[admin]` section of the configuration
+file (see [configuration file
+reference](@/documentation/reference-manual/configuration.md))
+
+**WARNING.** At this point, there is no comittement to stability of the APIs described in this document.
+We will bump the version numbers prefixed to each API endpoint at each time the syntax
+or semantics change, meaning that code that relies on these endpoint will break
+when changes are introduced.
+
+The Garage administration API was introduced in version 0.7.2, this document
+does not apply to older versions of Garage.
+
+
+## Access control
+
+The admin API uses two different tokens for acces control, that are specified in the config file's `[admin]` section:
+
+- `metrics_token`: the token for accessing the Metrics endpoint (if this token
+  is not set in the config file, the Metrics endpoint can be accessed without
+  access control);
+
+- `admin_token`: the token for accessing all of the other administration
+  endpoints (if this token is not set in the config file, access to these
+  endpoints is disabled entirely).
+
+These tokens are used as simple HTTP bearer tokens. In other words, to
+authenticate access to an admin API endpoint, add the following HTTP header
+to your request:
+
+```
+Authorization: Bearer <token>
+```
+
+## Administration API endpoints
+
+### Metrics-related endpoints
+
+#### Metrics `GET /metrics`
+
+Returns internal Garage metrics in Prometheus format.
+
+#### Health `GET /health`
+
+Used for simple health checks in a cluster setting with an orchestrator.
+Returns an HTTP status 200 if the node is ready to answer user's requests,
+and an HTTP status 503 (Service Unavailable) if there are some partitions
+for which a quorum of nodes is not available.
+A simple textual message is also returned in a body with content-type `text/plain`.
+See `/v0/health` for an API that also returns JSON output.
+
+### Cluster operations
+
+#### GetClusterStatus `GET /v0/status`
+
+Returns the cluster's current status in JSON, including:
+
+- ID of the node being queried and its version of the Garage daemon
+- Live nodes
+- Currently configured cluster layout
+- Staged changes to the cluster layout
+
+Example response body:
+

+```
+
+#### GetClusterHealth `GET /v0/health`
+
+Returns the cluster's current health in JSON format, with the following variables:
+
+- `status`: one of `Healthy`, `Degraded` or `Unavailable`:
+  - Healthy: Garage node is connected to all storage nodes
+  - Degraded: Garage node is not connected to all storage nodes, but a quorum of write nodes is available for all partitions
+  - Unavailable: a quorum of write nodes is not available for some partitions
+- `known_nodes`: the number of nodes this Garage node has had a TCP connection to since the daemon started
+- `connected_nodes`: the nubmer of nodes this Garage node currently has an open connection to
+- `storage_nodes`: the number of storage nodes currently registered in the cluster layout
+- `storage_nodes_ok`: the number of storage nodes to which a connection is currently open
+- `partitions`: the total number of partitions of the data (currently always 256)
+- `partitions_quorum`: the number of partitions for which a quorum of write nodes is available
+- `partitions_all_ok`: the number of partitions for which we are connected to all storage nodes responsible of storing it
+
+Contrarily to `GET /health`, this endpoint always returns a 200 OK HTTP response code.
+
+Example response body:
+
+```json
+{
+    "status": "Degraded",
+    "known_nodes": 3,
+    "connected_nodes": 2,
+    "storage_nodes": 3,
+    "storage_nodes_ok": 2,
+    "partitions": 256,
+    "partitions_quorum": 256,
+    "partitions_all_ok": 0
+}
+```
+
+#### ConnectClusterNodes `POST /v0/connect`
+
+Instructs this Garage node to connect to other Garage nodes at specified addresses.
+
+Example request body:
+
+```json
+[
+    "ec79480e0ce52ae26fd00c9da684e4fa56658d9c64cdcecb094e936de0bfe71f@10.0.0.11:3901",
+    "4a6ae5a1d0d33bf895f5bb4f0a418b7dc94c47c0dd2eb108d1158f3c8f60b0ff@10.0.0.12:3901"
+]
+```
+
+The format of the string for a node to connect to is: `<node ID>@<ip address>:<port>`, same as in the `garage node connect` CLI call.
+
+Example response:
+
+```json
+[
+    {
+        "success": true,
+        "error": null
+    },
+    {
+        "success": false,
+        "error": "Handshake error"
+    }
+]
+```
+
+#### GetClusterLayout `GET /v0/layout`
+
+Returns the cluster's current layout in JSON, including:
+
+- Currently configured cluster layout
+- Staged changes to the cluster layout
+
+(the info returned by this endpoint is a subset of the info returned by GetClusterStatus)
+
+Example response body:
+
+```json
+{
+  "version": 12,
+  "roles": {

+      "zone": "dc1",
+      "capacity": 6,
+      "tags": [
+        "node2"
+      ]
+    },
+    "23ffd0cdd375ebff573b20cc5cef38996b51c1a7d6dbcf2c6e619876e507cf27": {
+      "zone": "dc2",

+      "tags": [
+        "node4"
+      ]
+    }
+  }
+}
+```
+
+#### UpdateClusterLayout `POST /v0/layout`
+
+Send modifications to the cluster layout. These modifications will
+be included in the staged role changes, visible in subsequent calls
+of `GetClusterLayout`. Once the set of staged changes is satisfactory,
+the user may call `ApplyClusterLayout` to apply the changed changes,
+or `Revert ClusterLayout` to clear all of the staged changes in
+the layout.
+
+Request body format:
+
+```json
+{
+  <node_id>: {
+    "capacity": <new_capacity>,
+    "zone": <new_zone>,
+    "tags": [
+      <new_tag>,
+      ...
+    ]
+  },
+  <node_id_to_remove>: null,
+  ...
+}
+```
+
+Contrary to the CLI that may update only a subset of the fields
+`capacity`, `zone` and `tags`, when calling this API all of these
+values must be specified.
+
+
+#### ApplyClusterLayout `POST /v0/layout/apply`
+
+Applies to the cluster the layout changes currently registered as
+staged layout changes.
+
+Request body format:
+
+```json
+{
+  "version": 13
+}
+```
+
+Similarly to the CLI, the body must include the version of the new layout
+that will be created, which MUST be 1 + the value of the currently
+existing layout in the cluster.
+
+#### RevertClusterLayout `POST /v0/layout/revert`
+
+Clears all of the staged layout changes.
+
+Request body format:
+
+```json
+{
+  "version": 13
+}
+```
+
+Reverting the staged changes is done by incrementing the version number
+and clearing the contents of the staged change list.
+Similarly to the CLI, the body must include the incremented
+version number, which MUST be 1 + the value of the currently
+existing layout in the cluster.
+
+
+### Access key operations
+
+#### ListKeys `GET /v0/key`
+
+Returns all API access keys in the cluster.
+
+Example response:
+
+```json
+[
+  {
+    "id": "GK31c2f218a2e44f485b94239e",
+    "name": "test"
+  },
+  {
+    "id": "GKe10061ac9c2921f09e4c5540",
+    "name": "test2"
+  }
+]
+```
+
+#### CreateKey `POST /v0/key`
+
+Creates a new API access key.
+
+Request body format:
+
+```json
+{
+    "name": "NameOfMyKey"
+}
+```
+
+#### ImportKey `POST /v0/key/import`
+
+Imports an existing API key.
+
+Request body format:
+
+```json
+{
+    "accessKeyId": "GK31c2f218a2e44f485b94239e",
+    "secretAccessKey": "b892c0665f0ada8a4755dae98baa3b133590e11dae3bcc1f9d769d67f16c3835",
+    "name": "NameOfMyKey"
+}
+```
+
+#### GetKeyInfo `GET /v0/key?id=<acces key id>`
+#### GetKeyInfo `GET /v0/key?search=<pattern>`
+
+Returns information about the requested API access key.
+
+If `id` is set, the key is looked up using its exact identifier (faster).
+If `search` is set, the key is looked up using its name or prefix
+of identifier (slower, all keys are enumerated to do this).
+
+Example response:
+

+
+All fields (`name`, `allow` and `deny`) are optionnal.
+If they are present, the corresponding modifications are applied to the key, otherwise nothing is changed.
+The possible flags in `allow` and `deny` are: `createBucket`.
+
+
+### Bucket operations
+
+#### ListBuckets `GET /v0/bucket`
+
+Returns all storage buckets in the cluster.
+
+Example response:
+

+
+Returns information about the requested storage bucket.
+
+If `id` is set, the bucket is looked up using its exact identifier.

+(both are fast)
+
+Example response:
+
+```json
+{

+```
+
+#### CreateBucket `POST /v0/bucket`
+
+Creates a new storage bucket.
+
+Request body format:
+
+```json
+{
+    "globalAlias": "NameOfMyBucket"
+}
+```
+
+OR
+
+```json
+{
+    "localAlias": {

+        }
+    }
+}
+```
+
+OR
+
+```json
+{}
+```
+
+Creates a new bucket, either with a global alias, a local one,
+or no alias at all.
+
+Technically, you can also specify both `globalAlias` and `localAlias` and that would create
+two aliases, but I don't see why you would want to do that.
+
+#### DeleteBucket `DELETE /v0/bucket?id=<bucket id>`
+
+Deletes a storage bucket. A bucket cannot be deleted if it is not empty.
+
+Warning: this will delete all aliases associated with the bucket!
+
+#### UpdateBucket `PUT /v0/bucket?id=<bucket id>`
+
+Updates configuration of the given bucket.
+
+Request body format:
+
+```json
+{
+    "websiteAccess": {
+        "enabled": true,
+        "indexDocument": "index.html",
+        "errorDocument": "404.html"
+    },
+    "quotas": {
+        "maxSize": 19029801,
+        "maxObjects": null,
+    }
+}
+```
+
+All fields (`websiteAccess` and `quotas`) are optionnal.
+If they are present, the corresponding modifications are applied to the bucket, otherwise nothing is changed.
+
+In `websiteAccess`: if `enabled` is `true`, `indexDocument` must be specified.
+The field `errorDocument` is optional, if no error document is set a generic
+error message is displayed when errors happen. Conversely, if `enabled` is
+`false`, neither `indexDocument` nor `errorDocument` must be specified.
+
+In `quotas`: new values of `maxSize` and `maxObjects` must both be specified, or set to `null`
+to remove the quotas. An absent value will be considered the same as a `null`. It is not possible
+to change only one of the two quotas.
+
+### Operations on permissions for keys on buckets
+
+#### BucketAllowKey `POST /v0/bucket/allow`
+
+Allows a key to do read/write/owner operations on a bucket.
+
+Request body format:
+

+Deuxfleurs est une association militant en faveur d'un internet plus convivial, avec une organisation et des rapports de force repensés.\linebreak
+
+Nous faisons partie du CHATONS\footnote[frame]{Collectif des Hébergeurs Alternatifs, Transparents, Ouverts, Neutres et Solidaires} depuis avril 2022.

+\begin{frame}

+\begin{column}{0.5 \linewidth}
+\begin{center}
+Pour échapper au contrôle et au giron des opérateurs de clouds, héberger ses données à la maison présente de nombreux avantages...
+\end{center}
+
+\vspace{0.5cm}
+
+\begin{itemize}[<+(1)->]
+\item On récupère la souveraineté sur ses données
+\item On gagne en vie privée
+\item On gagne en libertés
+\item On est responsabilisé face à ses besoins
+\end{itemize}
+\end{column}

+\onslide<6->{... mais aussi bien des contraintes...}
+\end{center}
+
+\vspace{0.5cm}
+
+\begin{itemize}[<+(2)->]
+\item On repose sur une connexion internet pour particulier
+\item Un certain savoir-faire et moultes compétences sont requis
+\item Assurer la résilience de ses services est difficile
+\item Bien sauvegarder ses données, et ceci au-delà de son site géographique, n'est pas évident
+\end{itemize}
+\end{column}
+\end{columns}
+\end{frame}
+
+\subsection{Sauvegarder pour se parer à tout imprévu}
+\begin{frame}
+\begin{center}
+Sauvegarder pour se parer contre les pannes matérielles est une chose...
+
+Sauvegarder pour se parer contre les cambriolages et les incendies en est une autre !\linebreak

+\vspace{1cm}
+\onslide<2->{Répartir géographiquement ses données devient alors nécessaire.}
+\end{center}
+\end{frame}
+
+\section{Les solutions à explorer}
+\subsection{L'entre-hébergement}
+\begin{frame}
+\begin{center}
+On a vu récemment se développer au sein du CHATONS la notion d'entre-hébergement : en plus de renforcer l'intégrité des sauvegardes, on va améliorer la disponibilité pendant les coupures de liaison internet, de courant, ou pendant les déménagements d'administrateurs par exemple.\linebreak
+
+\vspace{1cm}
+\onslide<2->
+{
+Dans le cadre du collectif, il s'agit de partager ses volumes de données entre hébergeurs.\linebreak
+
+Pour assurer la confidentialité, on peut chiffrer les données au niveau applicatif.
+}
+\end{center}
+\end{frame}
+
+\subsection{S3 contre les systèmes de fichiers}
+\begin{frame}
+\begin{center}
+Dans le cadre de l'administration de services en ligne, les systèmes de fichiers recèlent certaines difficultés.\linebreak
+
+\vspace{1cm}
+Le standard S3 apporte des facilités; on réduit le stockage à un paradigme de clé-valeur basé essentiellement sur deux opérations seulement: lire ou écrire une clé.
+\end{center}
+\end{frame}
+
+\section{Garage}
+\subsection{Présentation}
+\begin{frame}
+\begin{columns}
+\column{0.5 \linewidth}
+\begin{center}
+Garage essaye de répondre à l'ensemble de ces besoins.\linebreak
+
+\vspace{0.5cm}
+Il s'agit d'un logiciel libre permettant de distribuer un service S3 sur diverses machines éloignées.
+\end{center}

+
+\texttt{https://garagehq.deuxfleurs.fr/}
+\end{center}
+\end{columns}
+\end{frame}
+
+\subsection{Gestion des zones}
+\begin{frame}
+\begin{center}
+Garage va prendre en compte les zones géographiques au moment de répliquer les données.\linebreak
+
+\vspace{1cm}
+\includegraphics[width=13.25cm]{zones.png}
+\end{center}
+\end{frame}
+
+\subsection{Comment ça marche ?}
+\begin{frame}
+\begin{columns}
+\column{0.5 \linewidth}
+\input{schéma europe}
+\column{0.5 \linewidth}
+\begin{center}
+Chaque objet est dupliqué sur plusieurs zones différentes.\linebreak
+
+\onslide<5->{Lorsqu'un nouvel hébergeur rejoint le réseau, la charge se voit équilibrée.}\linebreak
+
+\onslide<12->{Si une zone devient indisponible, les autres continuent d'assurer le service.}\linebreak
+\end{center}
+\end{columns}
+\end{frame}
+
+\subsection{Financement}
+\begin{frame}
+\begin{center}
+Dans le cadre du programme \textit{Horizon 2021} de l'Union Européenne, nous avons reçu une subvention de la part de l'initiative NGI Pointer\footnote[frame]{Next Generation Internet Program for Open Internet Renovation}.\linebreak
+
+\includegraphics[width=3cm]{drapeau_européen.png}\hspace{1cm}
+\includegraphics[width=3cm]{NGI.png}\linebreak
+
+Nous avons ainsi pu financer le développement de Garage pendant 1 an.
+\end{center}
+\end{frame}
+
+\subsection{Licence}
+\begin{frame}
+\begin{center}
+De par nos valeurs, nous avons attribué la licence AGPL version 3 à Garage, notamment afin qu'il reste parmi les biens communs.\linebreak
+
+\vspace{0.5cm}
+\includegraphics[width=5cm]{agpl-v3-logo.png}\linebreak
+\end{center}
+\end{frame}
+
+\subsection{Langage utilisé}
+\begin{frame}
+\begin{center}
+Nous avons décidé d'écrire Garage à l'aide du langage Rust, afin d'obtenir une compilation vers des binaires natifs et efficaces.\linebreak
+
+\includegraphics[width=3.5cm]{rust-logo.png}\linebreak
+
+Ce choix permet également de bénéficier des avantages reconnus de Rust en termes de sécurité.
+\end{center}
+\end{frame}
+
+\subsection{Matériel requis}
+\begin{frame}
+\begin{center}
+Garage peut ainsi être performant sur des machines limitées. Les prérequis sont minimes : n'importe quelle machine avec un processeur qui a moins d'une décennie, 1~gigaoctet de mémoire vive, et 16~gigaoctets de stockage suffit.\linebreak
+
+\vspace{1cm}
+
+Cet aspect est déterminant : il permet en effet d'héberger sur du matériel acheté d'occasion, pour réduire l'impact écologique de nos infrastructures.
+\end{center}
+\end{frame}
+
+\subsection{Performances}
+\begin{frame}
+\begin{center}

+\begin{frame}
+\begin{center}
+\includegraphics[width=11cm]{rpc-complexity.png}
+\end{center}
+\end{frame}
+
+\subsection{Services}
+\begin{frame}
+\begin{center}
+Puisqu'il suit le standard S3, beaucoup de services populaires sont par conséquence compatibles avec Garage :\linebreak
+
+\begin{columns}
+\column{0.2 \linewidth}
+\begin{center}
+\includegraphics[width=2.5cm]{nextcloud-logo.png}
+\end{center}

+\column{0.2 \linewidth}
+\begin{center}
+\includegraphics[width=2.5cm]{mastodon-logo.png}
+\end{center}
+\end{columns}
+~\linebreak
+
+Et comme souvent avec S3, on peut assimiler un bucket à un site, et utiliser le serveur pour héberger des sites web statiques.
+\end{center}
+\end{frame}
+
+\section{Intégration chez Deuxfleurs}
+\subsection{Matériel}
+\begin{frame}
+\begin{center}
+\includegraphics[width=13cm]{neptune.jpg}\linebreak
+
+En pratique, nos serveurs ne sont effectivement que des machines achetées d'occasion (très souvent des anciens ordinateurs destinés à la bureautique en entreprise).
+\end{center}
+\end{frame}
+
+\subsection{Environnement logiciel}
+\begin{frame}
+\begin{center}
+Pour faciliter la reproduction d'un environnement connu, NixOS est installé sur nos machines.\linebreak
+
+\vspace{1cm}
+Pour s’accommoder des réseaux qu'on trouve derrière des routeurs pour particuliers, on s'aide de notre logiciel Diplonat\footnote[frame]{\texttt{https://git.deuxfleurs.fr/Deuxfleurs/diplonat}}.
+\end{center}

+\subsection{... de Garage}
+\begin{frame}
+\begin{center}
+Nous avons récemment lancé le développement d'Aérogramme\footnote[frame]{\texttt{https://git.deuxfleurs.fr/Deuxfleurs/aerogramme}}.\linebreak
+
+\vspace{1cm}
+Il s'agit d'un serveur de stockage de courriels chiffrés.\linebreak
+
+\vspace{1cm}
+Il est conçu pour pouvoir travailler avec Garage.
