+## Ente
+
+Ente is an alternative for Google Photos and Apple Photos. It [can be selfhosted](https://help.ente.io/self-hosting/) and is working fine with Garage as of May 2024.
+As a first step we need to create a bucket and a key for Ente:
+
+```bash
+garage bucket create ente
+garage key create ente-key
+# For the CORS setup to work, the key needs to be --owner as well, at least temporarily.
+garage bucket allow ente --read --write --owner --key ente-key
+```
+
+We also need to setup some CORS rules to allow the Ente frontend to access the bucket:
+
+```bash
+export CORS='{"CORSRules":[{"AllowedHeaders":["*"],"AllowedMethods":["GET", "PUT", "POST", "DELETE"],"AllowedOrigins":["*"], "ExposeHeaders":["ETag"]}]}'
+aws s3api put-bucket-cors --bucket ente --cors-configuration $CORS
+```
+
+Now we need to configure ente-server to use our bucket. This is explained [in the Ente S3 documentation](https://help.ente.io/self-hosting/guides/external-s3).
+Prepare a configuration file for ente's backend as `museum.yaml`:
+
+```yaml

 ## Pleroma
 
-[Pleroma Documentation > Pleroma.Uploaders.S3](https://docs-develop.pleroma.social/backend/configuration/cheatsheet/#pleromauploaderss3)
+### Creating your bucket
+
+This is the usual Garage setup:
+
+```bash
+garage key new --name pleroma-key
+garage bucket create pleroma
+garage bucket allow pleroma --read --write --owner --key pleroma-key
+```
+
+We also need to expose these buckets publicly to serve their content to users:
+
+```bash
+garage bucket website --allow pleroma
+```
+
+Note the Key ID and Secret Key.
+
+### Configure Pleroma
+
+Update your Pleroma configuration like that in `/etc/pleroma/config.exs`.
+
+```
+config :pleroma, Pleroma.Upload,
+    uploader: Pleroma.Uploaders.S3,
+    base_url: "https://pleroma.garage.example.tld"
+
+config :ex_aws, :s3,
+    access_key_id: "GW...",
+    secret_access_key: "XXX",
+    region: "garage",
+    host: "api.garage.example.tld"
+```
+
+And restart Pleroma.
+
+You can found more information in [Pleroma Documentation > Pleroma.Uploaders.S3](https://docs-develop.pleroma.social/backend/configuration/cheatsheet/#pleromauploaderss3)

+        (pleroma 2.10.0) lib/pleroma/uploaders/uploader.ex:49: Pleroma.Uploaders.Uploader.put_file/2
+```
+
+So, use [your best tool](https://garagehq.deuxfleurs.fr/documentation/connect/cli/) to sync `/var/lib/pleroma/uploads/` in your S3.
+
+Then, to avoid some non existent problem (just in case of), run this command
+
+```bash
+while true
+do
+    rm -vr $(./bin/pleroma_ctl uploads migrate_local S3 2>&1 | grep "could not stream" | awk -F '"' '{print $2}')
+    sleep 5
+done
+```
+
+If you have many files, stop this command sometime and the command bellow (interactive) to delete local
+file after upload. Then restart the loop.
+
+```bash
+./bin/pleroma_ctl uploads migrate_local S3 --delete
+```
+
+And *voilà*

+
+An exhaustive list is maintained in the ["Integrations" > "Browsing tools" section](@/documentation/connect/_index.md).

+
+
+## Manual configuration
+
+This section provides instructions that are equivalent to using the
+`--single-node` and `--default-bucket` flags for automatic configuration.  If
+you are using an older version of Garage (before v2.3.0), you must follow
+these instructions as automatic configuration is not available.
+
+We will have to run quite a few `garage` administration commands to get started.
+If you ever get lost, don't forget that the `help` command and the `--help` flags can help you anywhere,
+the CLI tool is self-documented! Two examples:
+
+```
+garage help
+garage bucket allow --help
+```
+
+### Configuring the `garage` CLI
+
+Remember that the `garage` CLI needs to know the path of your `garage.toml` configuration file.
+If it is not in the default location of `/etc/garage.toml`, you can specify it either:
+
+- by setting the `GARAGE_CONFIG_FILE` environment variable;
+- by adding the `-c` flag to each `garage` command, for example: `garage -c ./garage.toml status`.
+
+If you are running Garage in a Docker container, you can set the following alias
+to provide a fake `garage`command that uses the Garage binary inside your container:
+
+```bash
+alias garage="docker exec -ti <container name>"
+```
+
+You can test that your `garage` CLI is configured correctly by running a basic command such as `garage status`.
+
+### Creating a cluster layout
+
+When you first start a cluster without automatic configuration, the output of `garage status` will look as follows:
 
 ```

 ```
 
-## Administration API endpoints
+### User-defined API tokens
+
+Cluster administrators may dynamically define administration tokens using the CLI commands under `garage admin-token`.
+Such tokens may be limited in scope, meaning that they may enable access to only a subset of API calls.
+They may also have an expiration date to limit their use in time.
+
+Here is an example to create an administration token that is valid for 30 days
+and gives access to only a subset of API calls, allowing it to create buckets
+and access keys and give keys permissions on buckets:
+
+```bash
+$ garage admin-token create --expires-in 30d \
+    --scope ListBuckets,GetBucketInfo,ListKeys,GetKeyInfo,CreateBucket,CreateKey,AllowBucketKey,DenyBucketKey \
+    my-token
+This is your secret bearer token, it will not be shown again by Garage:

+             DenyBucketKey
+```
+
+When running this command, your token will be shown only once and **will never
+be shown again by Garage**, so make sure to save it directly.  The token is
+hashed internally, and is identified by its prefix (32 hex digits followed by a
+dot) which is saved in clear.
+
+When running `garage admin-token list`, you might see something like this:

+```

+
+### Master API tokens
+
+The admin API can also use two different master tokens for access control,
+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 only possible with a user-defined admin token.
+
+With the introduction of multiple user-defined admin tokens, the use of master
+API tokens is now discouraged.
+
+
+## Using the admin API
+
+All of the admin API endpoints are described in the OpenAPI specification:
+
+ - APIv2 - [HTML spec](https://garagehq.deuxfleurs.fr/api/garage-admin-v2.html) - [OpenAPI JSON](https://garagehq.deuxfleurs.fr/api/garage-admin-v2.json)

+
+### Making API calls from the `garage` CLI
+
+Since v2.0.0, the `garage` binary provides a subcommand `garage json-api` that
+allows you to invoke the API without making an HTTP request.  This can be
+useful for scripting Garage deployments.
+
+`garage json-api` proxies API calls through Garage's internal RPC protocol,
+therefore it does not require any form of authentication: RPC connection
+parameters are discovered automatically to contact the locally-running Garage
+instance (as when running any other `garage` CLI command).
+
+For simple calls that take no parameters, usage is as follows:
+
+```
+$ garage json-api GetClusterHealth
+{
+  "connectedNodes": 3,
+  "knownNodes": 3,
+  "partitions": 256,
+  "partitionsAllOk": 256,
+  "partitionsQuorum": 256,
+  "status": "healthy",
+  "storageNodes": 3,
+  "storageNodesOk": 3
+}
+```
+
+If you need to specify a JSON body for your call, you can add it directly after
+the name of the function you are calling:
+
+```
+$ garage json-api CreateAdminToken '{"name": "test"}'
+```
+
+Or you can feed it through stdin by adding a `-` as the last command parameter:
+
+```
+$ garage json-api CreateAdminToken -
+{"name": "test"}
+<EOF>
+```
+
+For admin API calls that would have taken query parameters in their HTTP version, these parameters can be passed in the JSON body object:
+
+```
+$ garage json-api GetAdminTokenInfo '{"id":"b0e6e0ace2c0b2aca4cdb2de"}'
+```
+
+For admin API calls that take both query parameters and a JSON body, combine them in the following fashion:
+
+```
+$ garage json-api UpdateAdminToken '{"id":"b0e6e0ace2c0b2aca4cdb2de", "body":{"name":"not a test"}}'
+```

+
+## Changes introduced in v2.0
+
+The following are **breaking changes** in Garage v2.0 that require your attention when migrating:
+
+- The administration API has been completely reworked.
+  Some calls to the `/v1/` endpoints will still work but most will not.
+  New endpoints are prefixed by `/v2/`. **You will need to update all your code that makes use of the admin API.**
+
+- `replication_mode` is no longer a supported configuration parameter,
+  please use `replication_factor` and `consistency_mode` instead.
+
+## Migration procedure
+
+The migration to Garage v2.0 can be done with almost no downtime,
+by restarting all nodes at once in the new version.
+
+The migration steps are as follows:
+
+1. Do a `garage repair --all-nodes --yes tables`, check the logs and check that
+   all data seems to be synced correctly between nodes. If you have time, do
+   additional `garage repair` procedures (`blocks`, `versions`, `block_refs`,
+   etc.)
+
+2. Ensure you have a snapshot of your Garage installation that you can restore
+   to in case the upgrade goes wrong, with one of the following options:
+
+   - You may use the `garage meta snapshot --all` command
+     to make a backup snapshot of the metadata directories of your nodes
+     for backup purposes. Once this command has completed, copy the following
+     files and directories from the `metadata_dir` of all your nodes
+     to somewhere safe: `snapshots`, `cluster_layout`, `data_layout`,
+     `node_key`, `node_key.pub`. (If you have set the `metadata_snapshots_dir`
+     to a different value in your config file, back up that directory instead.)
+
+   - If you are running a filesystem such as ZFS or BTRFS that support
+     snapshotting, you can create a filesystem-level snapshot of the `metadata_dir`
+     of all your nodes to be used as a restoration point if needed.
+
+   - You may also make a back-up manually: turn off each node
+     individually; back up its metadata folder (for instance, use the following
+     command if your metadata directory is `/var/lib/garage/meta`: `cd
+     /var/lib/garage ; tar -acf meta-v1.0.tar.zst meta/`); turn it back on
+     again.  This will allow you to take a backup of all nodes without
+     impacting global cluster availability.  You can do all nodes of a single
+     zone at once as this does not impact the availability of Garage.
+
+3. Prepare your updated binaries and configuration files for Garage v2.0.
+   **Remember to update your configuration file to remove `replication_mode` and replace it by `replication_factor`.**
+
+4. Shut down all v1.0 nodes simultaneously, and restart them all simultaneously
+   in v2.0.  Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to
+   achieve this as fast as possible.  Garage v2.0 should be in a working state
+   as soon as enough nodes have started.
+
+5. Monitor your cluster in the following hours to see if it works well under
+   your production load.

+\end{frame}
+
+\begin{frame}
+	\frametitle{Things you should know}
+	\begin{itemize}
+		\item no TLS support, use your own proxy
+		\item no anonymous access (use website endpoint)
+		\item you need to assign roles to nodes manually
+        \item the replication factor cannot be changed easily
+        \item the default region is \texttt{garage} and not \texttt{us-east-1}
+        \item only use the \texttt{degraded} consistency policy for data recovery!
+	\end{itemize}
+\end{frame}
+
+\begin{frame}
+	\frametitle{What hardware should I use?}
+	\begin{itemize}
+	    \item do NOT use network file storage (NFS, SMB, etc.) for \texttt{\/metadata}
+		\item get a \textbf{write-intensive flash disk} for the \texttt{\/metadata} folder
+		\item set \texttt{metadata} on a RAID1 if possible, with a COW filesystem (e.g. Btrfs or ZFS)
+		\item get large HDDs for the \texttt{\/data} folder
+		\item use XFS and garage multi-hdd mode for best performance
+		\item you can use a RAID for data but you'll leave a lot of performance on the table
+	\end{itemize}
+	\center\textit{Garage doesn't require a powerful CPUs nor much RAM, but your performance will depend on your disks!}
+\end{frame}
+
+\begin{frame}
+	\frametitle{Picking a metadata engine}
+	All files-to-block mappings are stored in the metadata engine, including bucket and object metadata. Files below 3KB are stored directly in the metadata engine.
+    \vspace{1em}
+	\begin{itemize}
+        \item Sled: removed in 1.x, move to SQLite or LMDB
+	    \item \textbf{SQLite}: safer, \textbf{recommended for small clusters and single-node}
+        \item LMDB: faster, recommended for large clusters with metadata redundancy
+        \begin{itemize}
+            \item Warning: limited to 480 bytes per key with LMDB (not an issue in practice)
+        \end{itemize}
+        \item Fjall: experimental but promising rust-native engine, test it and let us know!
+	\end{itemize}
+	\center{Metadata engine can be set node per node, and changed later with a migration tool}
+\end{frame}
+
+\begin{frame}
+	\frametitle{Single-node deployment}
+	\begin{itemize}
+		\item garage was initially designed for multi-node deployments
+		\item single-node deployments are possible, but you will lose resilience
+		\item \textbf{If you do please ensure you have backups} (especially for metadata)
+		\begin{itemize}
+            \item set up \texttt{metadata\_auto\_snapshot\_interval}
+        \end{itemize}
+		\item use sqlite to minimize data loss risks on powercuts
+		\item or use a UPS!
+	\end{itemize}
+	\vspace{1em}
+	Use \texttt{github.com/bikeshedder/garage-single-node} for an easy single-node setup!
+\end{frame}
+
+\begin{frame}
+	\frametitle{Multi-node deployment}
+	\begin{itemize}
+		\item try to have geo-distributed zones
+		\item multiple nodes per zone to add more capacity
+		\item at least 3 zones for best resilience
+		\item keep in mind your available network and IO bandwidth
+		\item \textbf{Rebalancing a cluster can take multiple weeks with large HDDs and slow network links}
+		\item monitor your nodes with Prometheus + Grafana
+	\end{itemize}
+	\center{Deuxfleurs has been running a 9TB (3TB usable) 8-nodes cluster (3+3+2) over retail fiber (10ms site-to-site latency) for close to 5 years now. We heard there are petabyte clusters out there!}
+\end{frame}
+
+\begin{frame}
+	\frametitle{Deploying and administering garage at scale}
+	\begin{itemize}
+		\item deploy with your favorite tool (eg. Ansible) and system manager (eg. systemd)
+		\item or use Docker, docker-compose, Kubernetes or Nomad
+		\item Kubernetes and Consul are supported for node-to-node discovery
+		\begin{itemize}
+		\item you'll still have to manage the layout manually!
+        \end{itemize}
+		\item use gateway nodes to optimize network usage
+		\item ajust \texttt{resync-tranquility} and \texttt{scrub-tranquility} to your ressources

+		\item auth issues: check your reverse proxy configuration
+		\item slow resync: check your network and disk IO usage, and \texttt{resync-tranquility} worker configuration
+		\item big LMDB database: stop garage and compact with \texttt{mdb\_copy -c}
+		\item ask us on matrix \texttt{\#garage:deuxfleurs.fr} or open an issue on git.deuxfleurs.fr!
