+weight = 60
+++
+
+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,

+}
+```
+
+#### 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",

+]
+```
+
+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:

+      ]
+    }
+  }
+}
+```
+
+#### 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:

+    "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:
+
+```json
+[
+  {

+
+Returns information about the requested storage bucket.
+
+If `id` is set, the bucket is looked up using its exact identifier.
+If `globalAlias` is set, the bucket is looked up using its global alias.
+(both are fast)
+
+Example response:
+
+```json
+{

+```
+
+#### CreateBucket `POST /v0/bucket`
+
+Creates a new storage bucket.
+
+Request body format:
+
+```json
+{
+    "globalAlias": "NameOfMyBucket"
+}
+```
+
+OR
+
+```json
+{
+    "localAlias": {
+        "accessKeyId": "GK31c2f218a2e44f485b94239e",

+        }
+    }
+}
+```
+
+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",

+    "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:
+
+```json
+{
+    "bucketId": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",

+
+Flags in `permissions` which have the value `true` will be activated.
+Other flags will remain unchanged.
+
+#### BucketDenyKey `POST /v0/bucket/deny`
+
+Denies a key from doing read/write/owner operations on a bucket.
+
+Request body format:
+
+```json
+{
+    "bucketId": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",

+        "read": false,
+        "write": false,
+        "owner": true
+    },
+}
+```
+
+Flags in `permissions` which have the value `true` will be deactivated.
+Other flags will remain unchanged.
+
+
+### Operations on bucket aliases
+
+#### GlobalAliasBucket `PUT /v0/bucket/alias/global?id=<bucket id>&alias=<global alias>`
+
+Empty body. Creates a global alias for a bucket.

+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.

+\subsection{Héberger à la maison}
+\begin{frame}
+\begin{columns}
+\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}
+\vrule{}
+\begin{column}{0.5 \linewidth}
+\begin{center}
+\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}
+\column{0.5 \linewidth}
+\begin{center}
+\includegraphics[width=4cm]{garage-logo.png}\linebreak
+
+\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{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}

+\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}
+\end{frame}

+
+\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.

Maximilien R	980572a887	Merge pull request 'helm: ingress improvements' (#422 ) from patrickjahns:helm-refactor-ingress into main As discussed in the chat yesterday, I want to propose to disable the ingress per default. The motivation behind this change is, that per default the ingress is "misconfigured" meaning it can not work with the default values and requires a user of the chart to add additional configuration. When installing the chart per default, I would not expect to already expose garage publicly without my explicit configuration to do so Commenting the ingressClass resource also allows for relying only on annotations - otherwise the ingressClass would be always set to nginx or require a user to override it with ingressClass: null A small change on top, I've added the ability to specify user defined labels per ingress	2022-12-12 00:53:57 +01:00

Patrick Jahns	f58a813a36	refactor(helm): disable the ingress per default The default values forces people to create an ingress resources, where per default an ingress is not necessary to start garage. If someone wants to utilize an ingress, he would need to define the values for the ingress either way, so enabling the ingress explicitly makes more sense, then requiring it to be disabled per default	2022-12-11 23:11:56 +00:00
