linuxserver/socket-proxy
The Socket Proxy is a security-enhanced proxy which allows you to apply access rules to the Docker socket, limiting the attack surface for containers such as watchtower or Traefik that need to use it.

Supported Architectures
We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.Simply pulling
lscr.io/linuxserver/socket-proxy:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.The architectures supported by this image are:
| Architecture | Available | Tag | | :----: | :----: | ---- | | x86-64 | ✅ | amd64-\
Application Setup
This container is conceptually based on https://github.com/Tecnativa/docker-socket-proxy and as such does not follow our usual container conventions. It does not support mods or custom scripts/services, or running as a user other than root (or the docker user in a rootless environment). It is designed to act as a drop-in replacement for the Tecnativa container.The container should be run on the same docker network as the service(s) using it. Most containers that would normally connect to a mounted docker.sock can have their endpoint overridden using the
DOCKER_HOST environment variable if they do not offer the option in their configuration; it should typically be pointed to tcp://socket-proxy:2375.- Never expose this container's port to a public network. It should be treated the same way you would treat the docker socket or TCP endpoint.
- Revoke access to any API section that you consider your service should not need.
- To see the versions of the API your Docker daemon and client support, use
docker versionand check theAPI version. - Read the docs for the API version you are using for an explanation of all the available endpoints.
Podman / libpod API
Podman exposes two API groups on the same socket: the Docker-compatible API (controlled by the existing env vars above) and the libpod-native API prefixed with/libpod/. The LIBPOD_* environment variables control access to the libpod endpoints independently of their Docker-compat equivalents.For example, to use prometheus-podman-exporter, enable:
- LIBPOD_CONTAINERS=1
- LIBPOD_INFO=1
- LIBPOD_NETWORKS=1
- LIBPOD_PODS=1
- LIBPOD_VOLUMES=1
- LIBPOD_IMAGES=1
- LIBPOD_EVENTS=1Point the exporter at
tcp://socket-proxy:2375 using CONTAINER_HOST. LIBPOD_PING and LIBPOD_VERSION are enabled by default (like their Docker-compat counterparts PING and VERSION).Read-Only Operation
This image can be run with a read-only container filesystem. For details please read the docs.Usage
To help you get started creating a container from this image you can either use docker compose or the docker cli.>!NOTE >Unless a parameter is flaged as 'optional', it is mandatory and a value must be provided.

- Shell access whilst the container is running:
docker exec -it socket-proxy /bin/sh- To monitor the logs of the container in realtime:
docker logs -f socket-proxy- Container version number:
docker inspect -f '{{ index .Config.Labels "build_version" }}' socket-proxy- Image version number:
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/socket-proxy:latestUpdating Info
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.Below are the instructions for updating containers:
Via Docker Compose
- Update images:
```bash docker compose pull ```
Single image:
```bash docker compose pull socket-proxy ```
- Update containers:
```bash docker compose up -d ```
Single container:
```bash docker compose up -d socket-proxy ```
- You can also remove the old dangling images:
docker image pruneVia Docker Run
- Update the image:
docker pull lscr.io/linuxserver/socket-proxy:latest- Stop the running container:
docker stop socket-proxy- Delete the container:
docker rm socket-proxy- You can also remove the old dangling images:
docker image pruneImage Update Notifications - Diun (Docker Image Update Notifier)
>!TIP >We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.Building locally
If you want to make local modifications to these images for development purposes or just to customize the logic:git clone https://github.com/linuxserver/docker-socket-proxy.git
cd docker-socket-proxy
docker build \
--no-cache \
--pull \
-t lscr.io/linuxserver/socket-proxy:latest .The ARM variants can be built on x8664 hardware and vice versa using
lscr.io/linuxserver/docker-qemu-staticdocker run --rm --privileged lscr.io/linuxserver/docker-qemu-static --resetOnce registered you can define the dockerfile to use with

Serve Socket-proxy on your own domain behind Caddy, Nginx or Traefik. Fill in your domain and copy the result. It's a starting point, some apps need their own base URL or extra headers set too.
Proxying socket-proxy.example.com to http://Socket-proxy:80
Add this to your Caddyfile
socket-proxy.example.com {
reverse_proxy http://Socket-proxy:80
}Check the logs first
Nine times out of ten the logs tell you exactly what went wrong.
- In Portainer, go to Containers, click the container, then Logs. Or run
docker logs Socket-proxy - Exit codes help too:
137means killed, usually out of memory.126or127means the command inside the image is broken.
Port already in use
If deployment fails with "Bind for 0.0.0.0:80 failed: port is already allocated", something else on your server is using that port.
- Find what's using it:
sudo ss -tlnp | grep :80 - Stop the other service, or pick a different host port. In
80:80only the left number is yours to change, the right one belongs to the app.
Running but the page won't load
The container is up but nothing appears in your browser.
- Use your server's real IP:
http://your-server-ip:80. The 0.0.0.0 link Portainer shows isn't a real address. - Give it a minute after first deploy, Socket-proxy can take a while to initialise.
- Make sure your firewall allows the port, e.g.
sudo ufw allow 80
Permission denied on volumes
If the logs show "permission denied", the app can't write to its data folder on the host.
- Fix the ownership:
sudo chown -R 1000:1000 /srv/lsio/socket-proxy/config - Or set the
PUIDandPGIDvariables (defaults 1000:1000) to match your own user, found withid $USER
Image won't pull
Test the pull directly on the host: docker pull linuxserver/socket-proxy:latest
- "manifest unknown" means the tag no longer exists. This template uses
latest, so try pinning a specific version instead. - "toomanyrequests" is the Docker Hub rate limit. Log in with
docker loginto raise it. - "no space left on device" means a full disk. Reclaim space with
docker system prune
"exec format error"
This means the image was built for a different CPU architecture than your server.
- This image supports:
amd64, arm64, riscv64 - Check yours with
uname -m: x86_64 is amd64, aarch64 is arm64. Raspberry Pi and other ARM boards are the usual culprits.
Container keeps restarting
The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.
- Check the logs right after a restart, the last few lines before it died are the useful ones.
- Get the exit code with
docker inspect Socket-proxy --format '{{.State.ExitCode}}' - Still stuck? Redeploy once with the restart policy set to
noso the failure stays visible.
