|
|
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](https://distribution.github.io/distribution/spec/manifest-v2-2/#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
|
|
|
|
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-\<version tag\> |
|
|
| arm64 | ✅ | arm64v8-\<version tag\> |
|
|
| armhf | ❌ | |
|
|
|
|
## Application Setup
|
|
|
|
This container is based on [https://github.com/Tecnativa/docker-socket-proxy](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 version` and check the `API version`.
|
|
* [Read the docs](https://docs.docker.com/engine/api/) for the API version you are using for an explanation of all the available endpoints.
|
|
|
|
## Read-Only Operation
|
|
|
|
This image can be run with a read-only container filesystem. For details please [read the docs](https://docs.linuxserver.io/misc/read-only/).
|
|
|
|
## Usage
|
|
|
|

## Parameters
|
|
|
|
Containers are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.

|
|
|
|
## Updating 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](#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:
|
|
* All images:
|
|
|
|
```bash
|
|
docker compose pull
|
|
```
|
|
|
|
* Single image:
|
|
|
|
```bash
|
|
docker compose pull socket-proxy
|
|
```
|
|
|
|
* Update containers:
|
|
* All containers:
|
|
|
|
```bash
|
|
docker compose up -d
|
|
```
|
|
|
|
* Single container:
|
|
|
|
```bash
|
|
docker compose up -d socket-proxy
|
|
```
|
|
|
|
* You can also remove the old dangling images:
|
|
|
|
```bash
|
|
docker image prune
|
|
```
|
|
|
|
### Via Docker Run
|
|
|
|
* Update the image:
|
|
|
|
```bash
|
|
docker pull lscr.io/linuxserver/socket-proxy:latest
|
|
```
|
|
|
|
* Stop the running container:
|
|
|
|
```bash
|
|
docker stop socket-proxy
|
|
```
|
|
|
|
* Delete the container:
|
|
|
|
```bash
|
|
docker rm socket-proxy
|
|
```
|
|
|
|
* You can also remove the old dangling images:
|
|
|
|
```bash
|
|
docker image prune
|
|
```
|
|
|
|
### Image Update Notifications - Diun (Docker Image Update Notifier)
|
|
|
|
**tip**: We recommend [Diun](https://crazymax.dev/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:
|
|
|
|
```bash
|
|
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 x86_64 hardware using `multiarch/qemu-user-static`
|
|
|
|
```bash
|
|
docker run --rm --privileged multiarch/qemu-user-static:register --reset
|
|
```
|
|
|
|
Once registered you can define the dockerfile to use with `-f Dockerfile.aarch64`.
|
|
|
|
## Versions
|
|
|
|
* **26.08.24:** - Change `ALLOW_START`, `ALLOW_STOP`, and `ALLOW_RESTARTS` to work even with `POST=0`.
|
|
* **24.05.24:** - Rebase to Alpine 3.20.
|
|
* **15.04.24:** - Allow disabling IPv6 support for legacy devices.
|
|
* **08.04.24:** - Use nginx due to haproxy's wonky websockets handling.
