Fix garage admin service

DaemonSet is a k8s resource that schedules one instance per node,
which is useful for some garage deployment use cases, including
managing garage nodes using k8s node labels

+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).
+
+More information:
+  - [In the reference manual](@/documentation/reference-manual/admin-api.md)
+  - [Full specifiction](https://garagehq.deuxfleurs.fr/api/garage-admin-v0.html)

+## Admin API
+
+You need at least Python 3.6, pip, and setuptools.
+Because the python package is in a subfolder, the command is a bit more complicated than usual:
+
+```bash
+pip3 install --user 'git+https://git.deuxfleurs.fr/garage-sdk/garage-admin-sdk-python'
+```
+
+Now, let imagine you have a fresh Garage instance running on localhost, with the admin API configured on port 3903 with the bearer `s3cr3t`:
+
+```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" ],
+  )
+})

 ## Mastodon
 
-https://docs.joinmastodon.org/admin/config/#cdn
+Mastodon natively supports the S3 protocol to store media files, and it works out-of-the-box with Garage.
+You will need to expose your Garage bucket as a website: that way, media files will be served directly from Garage.
+
+### Performance considerations
+
+Mastodon tends to store many small objects over time: expect hundreds of thousands of objects,
+with average object size ranging from 50 KB to 150 KB.
+
+As such, your Garage cluster should be configured appropriately for good performance:
+
+- use Garage v0.8.0 or higher with the [LMDB database engine](@documentation/reference-manual/configuration.md#db-engine-since-v0-8-0).
+  With the default Sled database engine, your database could quickly end up taking tens of GB of disk space.
+- the Garage database should be stored on a SSD
+
+### Creating your bucket
+
+This is the usual Garage setup:
+
+```bash
+garage key new --name mastodon-key
+garage bucket create mastodon-data
+garage bucket allow mastodon-data --read --write --key mastodon-key
+```
+
+Note the Key ID and Secret Key.
+
+### Exposing your bucket as a website
+
+Create a DNS name to serve your media files, such as `my-social-media.mydomain.tld`.
+This name will be publicly exposed to the users of your Mastodon instance: they
+will load images directly from this DNS name.
+
+As [documented here](@/documentation/cookbook/exposing-websites.md),
+add this DNS name as alias to your bucket, and expose it as a website:
+
+```bash
+garage bucket alias mastodon-data my-social-media.mydomain.tld
+garage bucket website --allow mastodon-data
+```
+
+Then you will likely need to [setup a reverse proxy](@/documentation/cookbook/reverse-proxy.md)
+in front of it to serve your media files over HTTPS.
+
+### Cleaning up old media files before migration
+
+Mastodon instance quickly accumulate a lot of media files from the federation.
+Most of them are not strictly necessary because they can be fetched again from
+other servers.  As such, it is highly recommended to clean them up before
+migration, this will greatly reduce the migration time.
+
+From the [official Mastodon documentation](https://docs.joinmastodon.org/admin/tootctl/#media):
+
+```bash
+$ RAILS_ENV=production bin/tootctl media remove --days 3
+$ RAILS_ENV=production bin/tootctl media remove-orphans
+$ RAILS_ENV=production bin/tootctl preview_cards remove --days 15
+```
+
+Here is a typical disk usage for a small but multi-year instance after cleanup:
+
+```bash
+$ RAILS_ENV=production bin/tootctl media usage
+Attachments:	5.67 GB (1.14 GB local)
+Custom emoji:	295 MB (0 Bytes local)
+Preview cards:	154 MB
+Avatars:	3.77 GB (127 KB local)
+Headers:	8.72 GB (242 KB local)
+Backups:	0 Bytes
+Imports:	1.7 KB
+Settings:	0 Bytes
+```
+
+Unfortunately, [old avatars and headers cannot currently be cleaned up](https://github.com/mastodon/mastodon/issues/9567).
+
+### Migrating your data
+
+Data migration should be done with an efficient S3 client.
+The [minio client](@documentation/connect/cli.md#minio-client) is a good choice
+thanks to its mirror mode:
+
+```bash
+mc mirror ./public/system/ garage/mastodon-data
+```
+
+Here is a typical bucket usage after all data has been migrated:
+
+```bash
+$ garage bucket info mastodon-data
+
+Size: 20.3 GiB (21.8 GB)
+Objects: 175968
+```
+
+### Configuring Mastodon
+
+In your `.env.production` configuration file:
+
+```bash
+S3_ENABLED=true
+# Internal access to Garage
+S3_ENDPOINT=http://my-garage-instance.mydomain.tld:3900
+S3_REGION=garage
+S3_BUCKET=mastodon-data
+# Change this (Key ID and Secret Key of your Garage key)
+AWS_ACCESS_KEY_ID=GKe88df__CHANGETHIS__c5145
+AWS_SECRET_ACCESS_KEY=a2f7__CHANGETHIS__77fcfcf7a58f47a4aa4431f2e675c56da37821a1070000
+# What name gets exposed to users (HTTPS is implicit)
+S3_ALIAS_HOST=my-social-media.mydomain.tld
+```
+
+For more details, see the [reference Mastodon documentation](https://docs.joinmastodon.org/admin/config/#cdn).
+
+Restart all Mastodon services and everything should now be using Garage!
+You can check the URLs of images in the Mastodon web client, they should start
+with `https://my-social-media.mydomain.tld`.
+
+### Last migration sync
+
+After Mastodon is successfully using Garage, you can run a last sync from the local filesystem to Garage:
+
+```bash
+mc mirror --newer-than "3h" ./public/system/ garage/mastodon-data
+```

+Garage can also be deployed on a kubernetes cluster via helm chart.
+
+## Deploying
+
+Firstly clone the repository:
+
+```bash
+git clone https://git.deuxfleurs.fr/Deuxfleurs/garage
+cd garage/scripts/helm
+```
+
+Deploy with default options:
+
+```bash
+helm install --create-namespace --namespace garage garage ./garage
+```
+
+Or deploy with custom values:
+
+```bash
+helm install --create-namespace --namespace garage garage ./garage -f values.override.yaml
+```
+
+After deploying, cluster layout must be configured manually as described in [Creating a cluster layout](@/documentation/quick-start/_index.md#creating-a-cluster-layout). Use the following command to access garage CLI:
+
+```bash
+kubectl exec --stdin --tty -n garage garage-0 -- ./garage status
+```
+
+## Overriding default values
+
+All possible configuration values can be found with:
+
+```bash
+helm show values ./garage
+```
+
+This is an example `values.overrride.yaml` for deploying in a microk8s cluster with a https s3 api ingress route:
+
+```yaml
+garage:
+  # Use only 2 replicas per object
+  replicationMode: "2"
+
+  # Use recommended lmdb db engine
+  dbEngine: "lmdb"
+
+# Start 4 instances (StatefulSets) of garage

+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.

+
+- 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

+- For the data directory, Garage already does checksumming and integrity verification,

+  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.
+Check [our s3 compatibility list](@/documentation/reference-manual/s3-compatibility.md).

-
-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.

 should be counted to determine a node's capacity
 when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
 
+### `db_engine` (since `v0.8.0`)
+
+By default, Garage uses the Sled embedded database library
+to store its metadata on-disk. Since `v0.8.0`, Garage can use alternative storage backends as follows:
+
+| DB engine | `db_engine` value | Database path |
+| --------- | ----------------- | ------------- |
+| [Sled](https://sled.rs) | `"sled"` | `<metadata_dir>/db/` |
+| [LMDB](https://www.lmdb.tech) | `"lmdb"` | `<metadata_dir>/db.lmdb/` |
+| [Sqlite](https://sqlite.org) | `"sqlite"` | `<metadata_dir>/db.sqlite` |
+
+Performance characteristics of the different DB engines are as follows:
+
+- Sled: the default database engine, which tends to produce
+  large data files and also has performance issues, especially when the metadata folder
+  is on a traditionnal HDD and not on SSD.
+- LMDB: the recommended alternative on 64-bit systems,
+  much more space-efficiant and slightly faster. Note that the data format of LMDB is not portable
+  between architectures, so for instance the Garage database of an x86-64
+  node cannot be moved to an ARM64 node. Also note that, while LMDB can technically be used on 32-bit systems,
+  this will limit your node to very small database sizes due to how LMDB works; it is therefore not recommended.
+- Sqlite: Garage supports Sqlite as a storage backend for metadata,
+  however it may have issues and is also very slow in its current implementation,
+  so it is not recommended to be used for now.
+
+It is possible to convert Garage's metadata directory from one format to another with a small utility named `convert_db`,
+which can be downloaded at the following locations:
+[for amd64](https://garagehq.deuxfleurs.fr/_releases/convert_db/amd64/convert_db),
+[for i386](https://garagehq.deuxfleurs.fr/_releases/convert_db/i386/convert_db),
+[for arm64](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm64/convert_db),
+[for arm](https://garagehq.deuxfleurs.fr/_releases/convert_db/arm/convert_db).
+The `convert_db` utility is used as folows:
+
+```
+convert-db -a <input db engine> -i <input db path> \
+  		   -b <output db engine> -o <output db path>

+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.
+ - [FoundationDB Testing Approach](https://www.micahlerner.com/2021/06/12/foundationdb-a-distributed-unbundled-transactional-key-value-store.html#what-is-unique-about-foundationdbs-testing-framework). They chose to abstract "all sources of nondeterminism and communication are abstracted, including network, disk, time, and pseudo random number generator" to be able to run tests by simulating faults.

+# Library charts provide useful utilities or functions for the chart developer. They're included as
