linuxserver/code-server

Code-server is VS Code running on a remote server, accessible through the browser.

• Code on your Chromebook, tablet, and laptop with a consistent dev environment.
• If you have a Windows or Mac workstation, more easily develop for Linux.
• Take advantage of large cloud servers to speed up tests, compilations, downloads, and more.
• Preserve battery life when you're on the go.
• All intensive computation runs on your server.
• You're no longer running excess instances of Chrome.

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/code-server: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:

Application Setup

Access the webui at http://<your-ip>:8443. For github integration, drop your ssh key in to /config/.ssh. Then open a terminal from the top menu and set your github username and email via the following commands

git config --global user.name "username"
git config --global user.email "email address"

Hashed code-server password

How to create the hashed password.

Read-Only Operation

This image can be run with a read-only container filesystem. For details please read the docs.

Caveats

• /tmp must be mounted to tmpfs
• sudo will not be available

Non-Root Operation

This image can be run with a non-root user. For details please read the docs.

Caveats

• sudo will not be available

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 flagged as 'optional', it is mandatory and a value must be provided.

services:
  code-server:
    image: lscr.io/linuxserver/code-server:latest
    container_name: code-server
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - PASSWORD=password #optional
      - HASHED_PASSWORD= #optional

    volumes:
      - /path/to/code-server/config:/config
    ports:
      - 8443:8443
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=code-server \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e PASSWORD=password `#optional` \
  -e HASHED_PASSWORD= `#optional` \
  -e SUDO_PASSWORD=password `#optional` \
  -e SUDO_PASSWORD_HASH= `#optional` \
  -e PROXY_DOMAIN=code-server.my.domain `#optional` \
  -e DEFAULT_WORKSPACE=/config/workspace `#optional` \
  -e PWA_APPNAME=code-server `#optional` \
  -p 8443:8443 \
  -v /path/to/code-server/config:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/code-server:latest

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.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running:

  docker exec -it code-server /bin/bash
  

• To monitor the logs of the container in realtime:

  docker logs -f code-server
  

• Container version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' code-server
  

• Image version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/code-server:latest
  

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 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:

    docker-compose pull
    

  • Single image:

    docker-compose pull code-server
    

• Update containers:

  • All containers:

    docker-compose up -d
    

  • Single container:

    docker-compose up -d code-server
    

• You can also remove the old dangling images:

  docker image prune
  

Via Docker Run

• Update the image:

  docker pull lscr.io/linuxserver/code-server:latest
  

• Stop the running container:

  docker stop code-server
  

• Delete the container:

  docker rm code-server
  

• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)

• You can also remove the old dangling images:

  docker image prune
  

Image 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-code-server.git
cd docker-code-server
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/code-server:latest .

The ARM variants can be built on x86_64 hardware and vice versa using lscr.io/linuxserver/qemu-static

docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
