darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.

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/darktable 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 latest
arm64 arm64v8-latest

Application Setup

The application can be accessed at:

By default the user/pass is abc/abc, if you change your password or want to login manually to the GUI session for any reason use the following link:

Usage

Here are some example snippets to help you get started creating a container from this image.

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  darktable:
    image: ghcr.io/linuxserver/darktable
    container_name: darktable
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000
    restart: unless-stopped

docker cli

docker run -d \
  --name=darktable \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 3000:3000 \
  -v /path/to/config:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/darktable

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
3000 Darktable desktop gui.

Environment Variables (-e)

Env Function
PUID=1000 for UserID - see below for explanation
PGID=1000 for GroupID - see below for explanation
TZ=Europe/London Specify a timezone to use EG Europe/London.

Volume Mappings (-v)

Volume Function
/config Users home directory in the container, stores program settings and images

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.

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 user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

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