-
-We will see in this part how to set up a reverse proxy with [Traefik](https://docs.traefik.io/).
-
-Here is [a basic configuration file](https://doc.traefik.io/traefik/https/acme/#configuration-examples):
-
-```toml
-[entryPoints]
-  [entryPoints.web]
-    address = ":80"
-
-  [entryPoints.websecure]
-    address = ":443"
-
-[certificatesResolvers.myresolver.acme]

-  storage = "acme.json"
-  [certificatesResolvers.myresolver.acme.httpChallenge]
-    # used during the challenge
-    entryPoint = "web"
-```
-
-### Add Garage service
-
-To add Garage on Traefik you should declare a new service using its IP address (or hostname) and port:
-
-```toml
-[http.services]
-  [http.services.my_garage_service.loadBalancer]
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://xxx.xxx.xxx.xxx"
-      port = 3900
-```
-
-It's possible to declare multiple Garage servers as back-ends:
-
-```toml
-[http.services]
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://xxx.xxx.xxx.xxx"
-      port = 3900
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://yyy.yyy.yyy.yyy"
-      port = 3900
-    [[http.services.my_garage_service.loadBalancer.servers]]
-      url = "http://zzz.zzz.zzz.zzz"
-      port = 3900
-```
-
-Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
-
-```
-[http.services]
-  [http.services.my_garage_service.loadBalancer]

-      path = "/"
-      interval = "60s"
-      timeout = "5s"
-```
-
-### Adding a website
-
-To add a new website, add the following declaration to your Traefik configuration file:
-
-```toml
-[http.routers]
-  [http.routers.my_website]
-    rule = "Host(`yoururl.example.org`)"
-    service = "my_garage_service"
-    entryPoints = ["web"]
-```
-
-Enable HTTPS access to your website with the following configuration section ([documentation](https://doc.traefik.io/traefik/https/overview/)):
-
-```toml
-...
-    entryPoints = ["websecure"]
-    [http.routers.my_website.tls]
-      certResolver = "myresolver"
-...
-```
-
-### Adding gzip compression
-
-Add the following configuration section [to compress response](https://doc.traefik.io/traefik/middlewares/http/compress/) using [gzip](https://developer.mozilla.org/en-US/docs/Glossary/GZip_compression) before sending them to the client:
-
-```toml

-    ...
-    middlewares = ["gzip_compress"]
-    ...
-[http.middlewares]
-  [http.middlewares.gzip_compress.compress]
-```
-
-### Add caching response
-
-Traefik's caching middleware is only available on [entreprise version](https://doc.traefik.io/traefik-enterprise/middlewares/http-cache/), however the freely-available [Souin plugin](https://github.com/darkweak/souin#tr%C3%A6fik-container) can also do the job. (section to be completed)

-
-Your Caddy configuration can be as simple as:
-
-```caddy
-s3.garage.tld, *.s3.garage.tld {
-	reverse_proxy localhost:3900 192.168.1.2:3900 example.tld:3900

-}
-
-admin.garage.tld {
-	reverse_proxy localhost:3903
-}
-```
-
-But at the same time, the `reverse_proxy` is very flexible.
-For a production deployment, you should [read its documentation](https://caddyserver.com/docs/caddyfile/directives/reverse_proxy) as it supports features like DNS discovery of upstreams, load balancing with checks, streaming parameters, etc.

-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.
-
-### 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

-
-#### 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.

-
-Starting with version 0.7.2, Garage introduces an optionnal feature, K2V,
-which is an alternative storage API designed to help efficiently store
-many small values in buckets (in opposition to S3 which is more designed
-to store large blobs).
-
-K2V is currently disabled at compile time in all builds, as the
-specification is still subject to changes. To build a Garage version with
-K2V, the Cargo feature flag `k2v` must be activated.  Special builds with
-the `k2v` feature flag enabled can be obtained from our download page under
-"Extra builds": such builds can be identified easily as their tag name ends
-with `-k2v` (example: `v0.7.2-k2v`).
-
-The specification of the K2V API can be found
-[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md).
-This document also includes a high-level overview of K2V's design.
-
-The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
-The AWS region used for signature calculation is always the same as the one
-defined for the S3 API in the config file.
-
-## Enabling and using K2V
-
-To enable K2V, download and run a build that has the `k2v` feature flag
-enabled, or produce one yourself. Then, add the following section to your
-configuration file:
-
-```toml
-[k2v_api]
-api_bind_addr = "<ip>:<port>"
-```
-
-Please select a port number that is not already in use by another API
-endpoint (S3 api, admin API) or by the RPC server.
-
-We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
-
-```toml
-k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
-```
-
-There is also a simple CLI utility which can be built from source in the
-following way:
-
-```sh
-git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
-cd garage/src/k2v-client
-cargo build --features cli --bin k2v-cli
-```
-
-The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
-it. There is also a short README.md in the `src/k2v-client` folder with some
-instructions.
