linuxserver/remmina ¶

Remmina is a remote desktop client written in GTK, aiming to be useful for system administrators and travellers, who need to work with lots of remote computers in front of either large or tiny screens. Remmina supports multiple network protocols, in an integrated and consistent user interface. Currently RDP, VNC, SPICE, SSH and EXEC are supported.

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/remmina: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¶

The application can be accessed at:

http://yourhost:3000/
https://yourhost:3001/

Options in all KasmVNC based GUI containers¶

This container is based on Docker Baseimage KasmVNC which means there are additional environment variables and run configurations to enable or disable specific functionality.

Optional environment variables¶

Variable	Description
CUSTOM_PORT	Internal port the container listens on for http if it needs to be swapped from the default 3000.
CUSTOM_HTTPS_PORT	Internal port the container listens on for https if it needs to be swapped from the default 3001.
CUSTOM_USER	HTTP Basic auth username, abc is default.
PASSWORD	HTTP Basic auth password, abc is default. If unset there will be no auth
SUBFOLDER	Subfolder for the application if running a subfolder reverse proxy, need both slashes IE `/subfolder/`
TITLE	The page title displayed on the web browser, default "KasmVNC Client".
FM_HOME	This is the home directory (landing) for the file manager, default "/config".
START_DOCKER	If set to false a container with privilege will not automatically start the DinD Docker setup.
DRINODE	If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE `/dev/dri/renderD128`
LC_ALL	Set the Language for the container to run as IE `fr_FR.UTF-8` `ar_AE.UTF-8`
NO_DECOR	If set the application will run without window borders for use as a PWA.
NO_FULL	Do not autmatically fullscreen applications when using openbox.

Optional run configurations¶

Variable	Description
`--privileged`	Will start a Docker in Docker (DinD) setup inside the container to use docker in an isolated environment. For increased performance mount the Docker directory inside the container to the host IE `-v /home/user/docker-data:/var/lib/docker`.
`-v /var/run/docker.sock:/var/run/docker.sock`	Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications.
`--device /dev/dri:/dev/dri`	Mount a GPU into the container, this can be used in conjunction with the `DRINODE` environment variable to leverage a host video card for GPU accelerated appplications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau)

Language Support - Internationalization¶

The environment variable LC_ALL can be used to start this image in a different language than English simply pass for example to launch the Desktop session in French LC_ALL=fr_FR.UTF-8. Some languages like Chinese, Japanese, or Korean will be missing fonts needed to render properly known as cjk fonts, but others may exist and not be installed. We only ensure fonts for Latin characters are present. Fonts can be installed with a mod on startup.

To install cjk fonts on startup as an example pass the environment variables:

-e DOCKER_MODS=linuxserver/mods:universal-package-install
-e INSTALL_PACKAGES=fonts-noto-cjk
-e LC_ALL=zh_CN.UTF-8

The web interface has the option for "IME Input Mode" in Settings which will allow non english characters to be used from a non en_US keyboard on the client. Once enabled it will perform the same as a local Linux installation set to your locale.

Lossless mode¶

This container is capable of delivering a true lossless image at a high framerate to your web browser by changing the Stream Quality preset to "Lossless", more information here. In order to use this mode from a non localhost endpoint the HTTPS port on 3001 needs to be used. If using a reverse proxy to port 3000 specific headers will need to be set as outlined here.

Usage¶

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)¶

---
services:
  remmina:
    image: lscr.io/linuxserver/remmina:latest
    container_name: remmina
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000
      - 3001:3001
    restart: unless-stopped

docker cli (click here for more info)¶

docker run -d \
  --name=remmina \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -p 3000:3000 \
  -p 3001:3001 \
  -v /path/to/config:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/remmina: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.

Ports (`-p`)¶

Parameter	Function
`3000`	Remmina desktop gui.
`3001`	Remmina desktop gui HTTPS.

Environment Variables (`-e`)¶

Env	Function
`PUID=1000`	for UserID - see below for explanation
`PGID=1000`	for GroupID - see below for explanation
`TZ=Etc/UTC`	specify a timezone to use, see this list.

Volume Mappings (`-v`)¶

Volume	Function
`/config`	Users home directory in the container, stores program settings.

Miscellaneous Options¶

Parameter	Function

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 remmina /bin/bash
```
To monitor the logs of the container in realtime:
```
docker logs -f remmina
```

Container version number:

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

Image version number:

docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/remmina: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 remmina
```

Update containers:

All containers:
```
docker-compose up -d
```
Single container:
```
docker-compose up -d remmina
```

You can also remove the old dangling images:
```
docker image prune
```

Via Docker Run¶

Update the image:

docker pull lscr.io/linuxserver/remmina:latest

Stop the running container:
```
docker stop remmina
```
Delete the container:
```
docker rm remmina
```
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-remmina.git
cd docker-remmina
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/remmina:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

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