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.

Parameter	Function
`-p 8443:8443`	web gui
`-e PUID=1000`	for UserID - see below for explanation
`-e PGID=1000`	for GroupID - see below for explanation
`-e TZ=Etc/UTC`	specify a timezone to use, see this list.
`-e PASSWORD=password`	Optional web gui password, if `PASSWORD` or `HASHEDPASSWORD` is not provided, there will be no auth.
`-e HASHEDPASSWORD=`	Optional web gui password, overrides `PASSWORD`, instructions on how to create it is below.
`-e SUDOPASSWORD=password`	If this optional variable is set, user will have sudo access in the code-server terminal with the specified password.
`-e SUDOPASSWORDHASH=`	Optionally set sudo password via hash (takes priority over `SUDOPASSWORD` var). Format is `$type$salt$hashed`.
`-e PROXYDOMAIN=code-server.my.domain`	If this optional variable is set, this domain will be proxied for subdomain proxying. See Documentation
`-e DEFAULTWORKSPACE=/config/workspace`	If this optional variable is set, code-server will open this directory by default
`-e PWAAPPNAME=code-server`	If this optional variable is set, the PWA app will the specified name.
`-v /config`	Contains all relevant configuration files.
`--read-only=true`	Run container with a read-only filesystem. Please read the docs.
`--user=1000:1000`	Run container with a non-root user. Please read the docs.

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:

```bash
docker exec -it code-server /bin/bash
```

To monitor the logs of the container in realtime:

```bash
docker logs -f code-server
```

Container version number:

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

Image version number:

```bash
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:

    ```bash
    docker-compose pull
    ```

* Single image:

    ```bash
    docker-compose pull code-server
    ```

Update containers:

* All containers:

    ```bash
    docker-compose up -d
    ```

* Single container:

    ```bash
    docker-compose up -d code-server
    ```

You can also remove the old dangling images:

```bash
docker image prune
```

Via Docker Run

Update the image:

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

Stop the running container:

```bash
docker stop code-server
```

Delete the container:

```bash
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:

```bash
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 x8664 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.

Serve Code-server {shmolf} 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.

Proxy Domain App port Upstream

Proxying code-server-shmolf.example.com to https://code-server:8443

Add this to your Caddyfile

code-server-shmolf.example.com {
	reverse_proxy https://code-server:8443 {
		transport http {
			tls_insecure_skip_verify
		}
	}
}

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 code-server
Exit codes help too: 137 means killed, usually out of memory. 126 or 127 means the command inside the image is broken.

Port already in use

If deployment fails with "Bind for 0.0.0.0:8443 failed: port is already allocated", something else on your server is using that port.

Find what's using it: sudo ss -tlnp | grep :8443
Stop the other service, or pick a different host port. In 8443:8443 only 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:8443. The 0.0.0.0 link Portainer shows isn't a real address.
Give it a minute after first deploy, code-server can take a while to initialise.
Make sure your firewall allows the port, e.g. sudo ufw allow 8443

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 /portainer/Files/AppData/Config/code-server
Or set the PUID and PGID variables (defaults 1000:1000) to match your own user, found with id $USER

Image won't pull

Test the pull directly on the host: docker pull linuxserver/code-server: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 login to 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
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 code-server --format '{{.State.ExitCode}}'
Still stuck? Redeploy once with the restart policy set to no so the failure stays visible.

Required settings are blank

HASHED_PASSWORD, SUDO_PASSWORD_HASH have no default value, and code-server may crash or misbehave if left empty.

Fill them in on the deploy screen before hitting deploy.

Raise an issue

Template not working: Open an issue on shmolf/portainer-templates
This website not working: Open an issue on lissy93/portainer-templates

A single container

Code-server {shmolf} runs as one container, the simplest kind of app here. Just the one image to pull and nothing else wired up alongside it.

The app image

An image is the app packed up ready to go, everything Code-server {shmolf} needs bundled into one download. This template pulls linuxserver/code-server:latest, which Docker fetches once (about 303 MB) and then starts your own copy from.

Where the image comes from

Docker pulls its images from registries, public libraries of ready-built apps. Code-server {shmolf}'s comes from Docker Hub, published by linuxserver.

Version tags

The bit after the colon in the image name is the version tag. Here it's latest, which always points at the newest build, so a redeploy can bump you to a newer release without you asking. Newest right now is 4.132.0. Pin a specific tag if you would rather stay on one version.

Which machines it runs on

Every image is built for particular CPU types. This one ships for amd64, arm64, so it runs on both regular x86 servers and ARM boards like a Raspberry Pi.

Ports

A port is the door the app answers on. A mapping like 8443:8443 means it's reachable on port 8443 of your server, where the left number is yours to change and the right one belongs to the app. It opens:

8443:8443

Volumes

A volume is where Code-server {shmolf} keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:

/config from /portainer/Files/AppData/Config/code-server on the host

Environment variables

Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Code-server {shmolf} takes 9 of them, and 2 need a value before it'll start properly:

PUID, defaults to 1000. For UserID
PGID, defaults to 1000. For GroupID
TZ, defaults to Europe/Amsterdam. Specify a timezone to use
PASSWORD, defaults to password. Optional web gui password, if PASSWORD or HASHEDPASSWORD is not provided, there will be no auth.
HASHED_PASSWORD, needs a value. Optional web gui password, overrides PASSWORD, instructions on how to create it is below.
SUDO_PASSWORD, defaults to password. If this optional variable is set, user will have sudo access in the code-server terminal with the specified password.
SUDO_PASSWORD_HASH, needs a value. Optionally set sudo password via hash (takes priority over SUDOPASSWORD var). Format is $type$salt$hashed.
PROXY_DOMAIN, defaults to code-server.my.domain. If this optional variable is set, this domain will be proxied for subdomain proxying.
DEFAULT_WORKSPACE, defaults to /config/workspace. If this optional variable is set, code-server will open this directory by default

Restart policy

The restart policy here is unless-stopped, so Docker restarts Code-server {shmolf} after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).

Users and permissions

The PUID and PGID settings tell it which user and group to act as on your host. Point them at your own account (find yours with id $USER) so the files it writes into your mounted folders come out owned by you rather than root.

Networking

Nothing custom is set, so Code-server {shmolf} sits on Docker's default bridge network: its own private space that reaches the outside world only through the ports it publishes.

Container name

Once it's deployed, Portainer names the container code-server. That's what you'll spot in the containers list and use in commands like docker logs code-server.

Platform

The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.

Open source license

Code-server {shmolf} is open source, released under the MIT license. In plain terms the code is out in the open, so you're free to run it and change it to fit what you need.

Portainer app templates

Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set Code-server {shmolf} up. Add the template list to Portainer once, then deploying Code-server {shmolf} is a click rather than a wall of config.
