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 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:
amd64-<version tag>
arm64v8-<version tag>

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.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.
version: "2.1"
container_name: fleet
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- fleet_admin_authentication_type=DATABASE
- fleet_database_url=jdbc:mariadb://<url>:3306/fleet
- fleet_database_username=fleet_user
- fleet_database_password=dbuserpassword
- fleet_admin_secret=randomstring #optional
- /path/to/appdata/config:/config
- 8080:8080
restart: unless-stopped
docker run -d \
--name=fleet \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=Etc/UTC \
-e fleet_admin_authentication_type=DATABASE \
-e fleet_database_url=jdbc:mariadb://<url>:3306/fleet \
-e fleet_database_username=fleet_user \
-e fleet_database_password=dbuserpassword \
-e fleet_admin_secret=randomstring `#optional` \
-p 8080:8080 \
-v /path/to/appdata/config:/config \
--restart unless-stopped \


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)

Http port

Environment Variables (-e)

for UserID - see below for explanation
for GroupID - see below for explanation
specify a timezone to use, see this list.
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.
The full JDBC connection string to the Fleet database
The username with the relevant GRANT permissions for the database
The database user's password.
A string used as part of the password key derivation process.

Volume Mappings (-v)

The primary config file and rolling log files.

Miscellaneous Options

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

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" }}'
