--- title: Arcane description: Install Arcane, a modern Docker and Compose management web UI, as a more advanced alternative to Dockge with multi-host support and OIDC login. --- :ellipsis{left=0px width=40rem top=10rem blur=140px zIndex=60} ::note{to="/serveex/core/docker#installer-dockge-pour-gérer-et-déployer-les-conteneurs"} This is an advanced alternative to **Dockge**: it can manage several remote Docker hosts from a single instance, and supports OIDC login natively instead of relying on a separate forward-auth proxy. :: [Arcane](https://github.com/getarcaneapp/arcane) is a self-hosted web UI for managing Docker containers, images, volumes, and Compose stacks. ![Arcane](/img/serveex/arcane.png) - [Arcane documentation](https://getarcane.app/docs/) - [Arcane on GitHub](https://github.com/getarcaneapp/arcane) ::note{to="https://docs.linuxserver.io/images/docker-socket-proxy/"} Arcane needs access to the Docker socket to manage containers, which is effectively root access to your host. Instead of mounting the socket directly, this guide sits **Docker Socket Proxy** in front of it, only allowing the specific API permissions Arcane actually needs. Whatever you use, make sure Arcane itself is never reachable without authentication. :: ## Installation ::file-tree --- tree: /: - docker: - arcane: - compose.yaml - .env - data/ --- :: ::steps{level="3"} ### Generate an encryption key ```bash [Terminal] openssl rand -base64 32 ``` Keep the output, you'll need it for the `.env` file below. ### Deploy the stack Open Dockge, click `compose`, name the stack `arcane`, and add the following config. It includes the socket proxy: `arcane` never touches `/var/run/docker.sock` directly, only `docker-socket-proxy` does, and it only allows the specific permissions Arcane needs (containers, images, networks, volumes, exec, build/commit), on their own internal network: ```yaml [compose.yaml] --- services: arcane: image: ghcr.io/getarcaneapp/manager:latest container_name: arcane restart: unless-stopped cgroup: host env_file: - .env volumes: - /docker/arcane/data:/app/data networks: - arcane-internal ports: - 3552:3552 depends_on: - docker-socket-proxy docker-socket-proxy: image: lscr.io/linuxserver/socket-proxy:latest container_name: arcane-docker-proxy security_opt: - no-new-privileges:true networks: - arcane-internal volumes: - /var/run/docker.sock:/var/run/docker.sock:ro environment: - CONTAINERS=1 - IMAGES=1 - NETWORKS=1 - VOLUMES=1 - EXEC=1 - BUILD=1 - COMMIT=1 - INFO=1 - SYSTEM=1 - POST=1 - ALLOW_START=1 - ALLOW_STOP=1 - ALLOW_RESTARTS=1 restart: unless-stopped read_only: true tmpfs: - /run networks: arcane-internal: name: arcane-internal ``` ::note `POST=1` is the blanket write-enable needed for creating/removing containers, images, networks and volumes; `ALLOW_START`/`ALLOW_STOP`/`ALLOW_RESTARTS` cover container lifecycle actions separately. Everything else (Swarm, secrets, configs, auth) is left at its default `0`, since this site doesn't use them. :: ::tip{icon=""} ✨ Add the Watchtower label to automate updates: ```yaml [compose.yaml] --- services: arcane: #... labels: - com.centurylinklabs.watchtower.enable=true ``` :: ### Set your environment variables Fill in the `.env` file: ```properties [.env] APP_URL=https://arcane.mydomain.com ENCRYPTION_KEY= DOCKER_HOST=tcp://docker-socket-proxy:2375 PUID=1000 PGID=1000 ``` | Variable | Value | Example | |----------|-------|---------| | `APP_URL`{lang=properties} | The public URL you'll use to reach Arcane (see exposure below), without a port | `https://arcane.mydomain.com` | | `ENCRYPTION_KEY`{lang=properties} | The key generated above | `Q2pVEqsTNRkJSO9SkJzU3KZ2...` | | `DOCKER_HOST`{lang=properties} | Points Arcane at the socket proxy instead of a mounted socket | `tcp://docker-socket-proxy:2375` | | `PUID` / `PGID`{lang=properties} | Your user and group ID, from `id yourusername` | `1000` | Deploy the stack. The local interface is available at `http://yourserverip:3552`. ### Done ! :: ::caution __If it fails:__ check your firewall rules. :: ## Exposing Arcane with SWAG The main benefit of this setup is being able to access Arcane remotely from all your devices. We'll expose it using SWAG. ::warning Arcane's own local login has no multi-factor authentication. Only expose it if you're using [Pocket ID](/serveex/security/pocket-id) (see below) or [Authentik](/serveex/advanced/authentik) for login. Otherwise, don't expose it with SWAG. Use a VPN like [Wireguard](/serveex/core/wireguard) instead, especially given the level of access Arcane has over your host. :: ::note We assume you have the subdomain `arcane.mydomain.com` with a `CNAME` pointing to `mydomain.com` in your [DNS zone](/general/networking/dns). And of course, [unless you use Cloudflare Zero Trust](/serveex/security/cloudflare), your box's port `443` must be forwarded to your server's port `443` in [NAT rules](/general/networking/nat). :: ::steps{level="3"} ### Add Arcane's network to SWAG Go to Dockge and edit SWAG's compose file by adding Arcane's network: ```yaml [compose.yaml] --- services: swag: container_name: # ... # ... networks: # Attach container to custom network # ... - arcane # Name of the declared network networks: # Define the custom network # ... arcane: # Declared network name name: arcane_default # Actual external network name external: true # Marks it as externally defined ``` Redeploy the stack and wait for SWAG to be fully operational. ::note Here we assume the Arcane network name is `arcane_default`. You can check the connection by visiting SWAG's dashboard at `http://yourserverip:81`. :: ### Create the subdomain.conf file In the Swag folders, create the file `arcane.subdomain.conf`: ::tip{icon="" to="/serveex/files/file-browser-quantum"} ✨ __Tip:__ Use **File Browser Quantum** to navigate and edit files instead of using terminal commands. :: ```bash [Terminal] sudo nano /docker/swag/config/nginx/proxy-confs/arcane.subdomain.conf ``` Paste the following configuration: ```nginx [arcane.subdomain.conf] ## Version 2023/12/19 server { listen 443 ssl; listen [::]:443 ssl; server_name arcane.*; include /config/nginx/ssl.conf; client_max_body_size 0; location / { include /config/nginx/proxy.conf; include /config/nginx/resolver.conf; set $upstream_app arcane; set $upstream_port 3552; set $upstream_proto http; proxy_pass $upstream_proto://$upstream_app:$upstream_port; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } ``` ::note Arcane's live updates run over a websocket, hence the `Upgrade`/`Connection` headers above, on top of the usual `proxy.conf` include. :: Press :kbd{value="Ctrl+O"}, then :kbd{value="Enter"} to save, and :kbd{value="Ctrl+X"} to exit. ### Done ! :: That's it! Arcane is now accessible from the internet. ## Connecting a Remote Host Arcane can manage several Docker hosts from a single instance. Each remote host runs a lightweight **agent** container that connects back to Arcane. Rather than exposing that connection to the internet, we'll route it over the [WireGuard VPN](/serveex/core/wireguard) already set up earlier, so the agent traffic never leaves your private network. ::note{to="/serveex/core/wireguard#client-server-setup"} This assumes both the Arcane host and the remote host already run their own WireGuard client, connected to your VPN as described in **Client Server Setup**. Note the VPN address wg-easy assigned to the __Arcane host__ (e.g. `10.8.0.3`); that's the address the remote agent will target below. :: ::steps{level="3"} ### Add the remote environment in Arcane In Arcane, go to _Environments > Add Environment_. Arcane generates a one-time __Agent Token__ and the compose snippet to deploy on the remote host. ### Deploy the agent on the remote host On the remote host, open Dockge, click `compose`, name the stack `arcane-agent`, and add the following config, replacing the token with the one Arcane gave you and the URL with your Arcane host's VPN address: ```yaml [compose.yaml] --- services: arcane-agent: image: ghcr.io/getarcaneapp/agent:latest container_name: arcane-agent restart: unless-stopped environment: - EDGE_AGENT=true - EDGE_TRANSPORT=poll - AGENT_TOKEN=arc_yourtoken - MANAGER_API_URL=http://10.8.0.3:3552 volumes: - /var/run/docker.sock:/var/run/docker.sock - /docker/arcane-agent/data:/app/data ``` ::note This is "edge mode": the agent connects out to Arcane instead of the other way around, so it works from behind NAT without forwarding anything on the remote host's router. Using the VPN address instead of a public domain means that connection stays on the WireGuard tunnel even though the agent is technically in "edge" mode. Unlike the manager above, the agent needs the real Docker socket mounted directly, since it's the one actually running commands on that host; there's no documented socket-proxy option for it. :: Deploy the stack. ### Verify the connection Back in Arcane, the new environment should show as connected within a few seconds. Switch to it from the environment picker to manage that host's containers and stacks. ### Done ! :: ## Connecting Pocket ID Arcane supports OIDC natively, so you can require a Pocket ID login before letting anyone manage your containers, instead of (or alongside) the app's own accounts. ::steps{level="3"} ### Register Arcane as an OIDC client [Register an OIDC client in Pocket ID](/serveex/security/pocket-id#registering-an-oidc-client) named `arcane`, with this callback URL: ```text https://arcane.mydomain.com/auth/oidc/callback ``` ### Enable OIDC in Arcane Edit Arcane's `.env` file and add: ```properties [.env] OIDC_ENABLED=true OIDC_CLIENT_ID= OIDC_CLIENT_SECRET= OIDC_ISSUER_URL=https://id.mydomain.com OIDC_SCOPES=openid email profile OIDC_PROVIDER_NAME=Pocket ID ``` | Variable | Value | |----------|-------| | `OIDC_CLIENT_ID`{lang=properties} | The client ID copied from Pocket ID | | `OIDC_CLIENT_SECRET`{lang=properties} | The client secret copied from Pocket ID | | `OIDC_ISSUER_URL`{lang=properties} | Pocket ID's public URL, no trailing slash; Arcane discovers the rest via `.well-known/openid-configuration` | Redeploy the stack. ::tip{icon=""} ✨ To skip straight to Pocket ID and hide the local login form, set `OIDC_AUTO_REDIRECT_TO_PROVIDER=true`, or disable local login entirely under _Settings > Authentication_ for OIDC-only access. :: ### Done ! :: That's it! Arcane now offers a "Login with Pocket ID" option alongside the local login form. ::tip{icon="" to="/serveex/advanced/authentik"} ✨ You can use **Authentik** instead of Pocket ID: 1. In Authentik, create an application and an OAuth2/OpenID Connect provider named `Arcane`, with a redirect URI (type `Strict`) of `https://arcane.mydomain.com/auth/oidc/callback`. 2. Note the provider's __Client ID__ and __Client Secret__. 3. In Arcane's `.env`, set `OIDC_ISSUER_URL=https://authentik.mydomain.com/application/o/arcane/`, then fill in the Client ID and Client Secret. ::
