linuxserver/fleet

Fleet provides an online web interface which displays a set of maintained images from one or more owned repositories.

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/fleet: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

Navigate to http://your_ip_here:8080 to display the home page. If DATABASE is selected as the preferred authentication process, ensure that you set up an initial user via http://your_ip_here:8080/setup. Once done, that page will no longer be available. A restart is preferable as it will remove the page altogether. Once complete, you can log into the app via http://your_ip_here:8080/login to manage your repositories.

Read-Only Operation

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

Non-Root Operation

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

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

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

docker run -d \

  --restart unless-stopped \
  lscr.io/linuxserver/fleet: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.

Parameter	Function
-p 8080:8080	Http port
-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 fleet_admin_authentication_type=DATABASE	A switch to define how Fleet manages user logins. If set to DATABASE, see the related optional params. Can be set to either DATABASE or PROPERTIES.
-e fleet_database_url=jdbc:mariadb://<url>:3306/fleet	The full JDBC connection string to the Fleet database
-e fleet_database_username=fleet_user	The username with the relevant GRANT permissions for the database
-e fleet_database_password=dbuserpassword	The database user's password.
-e fleet_admin_secret=randomstring	A string used as part of the password key derivation process.
-v /config	The primary config file and rolling log 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:

  docker exec -it fleet /bin/bash

• To monitor the logs of the container in realtime:

  docker logs -f fleet

• Container version number:

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

• Image version number:

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

• Update containers:

  • All containers:

    docker-compose up -d

  • Single container:

    docker-compose up -d fleet

• You can also remove the old dangling images:

  docker image prune

Via Docker Run

• Update the image:

  docker pull lscr.io/linuxserver/fleet:latest

• Stop the running container:

  docker stop fleet

• Delete the container:

  docker rm fleet

• 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-fleet.git
cd docker-fleet
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/fleet: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.
