guacd

linuxserver/guacd

Guacd - Apache Guacamole is a clientless remote desktop gateway. It supports standard protocols like VNC, RDP, and SSH. This container is only the backend server component needed to use The official or 3rd party HTML5 frontends.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling ghcr.io/linuxserver/guacd 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	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Application Setup

This is a backend only service, to leverage Guacd server you need to use either the official Java frontend guacamole-client or an open source alterantive like guacamole-lite.

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)

---
version: "2.1"
services:
  guacd:
    image: ghcr.io/linuxserver/guacd
    container_name: guacd
    ports:
      - 4822:4822
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=guacd \
  -p 4822:4822 \
  --restart unless-stopped \
  ghcr.io/linuxserver/guacd

Parameters

Docker images 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
`4822`	Port Guacamole server listens on

Environment Variables (`-e`)

Env	Function

Volume Mappings (`-v`)

Volume	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__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword 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.

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 guacd /bin/bash
To monitor the logs of the container in realtime:
- docker logs -f guacd
Container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' guacd
Image version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/guacd
