Common files

File	Use case
Dockerfile	Dockerfile used to build amd64 images
Dockerfile.aarch64	Dockerfile used to build 64bit ARM architectures
Dockerfile.armhf	Dockerfile used to build 32bit ARM architectures
Jenkinsfile	This file is a product of our builder and should not be edited directly. This is used to build the image
jenkins-vars.yml	This file is used to generate the Jenkinsfile mentioned above, it only affects the build-process
package_versions.txt	This file is generated as a part of the build-process and should not be edited directly. It lists all the installed packages and their versions
README.md	This file is a product of our builder and should not be edited directly. This displays the readme for the repository and image registries
readme-vars.yml	This file is used to generate the README.md

Readme

If you would like to change our readme, please do not directly edit the readme, as it is auto-generated on each commit. Instead edit the readme-vars.yml.

These variables are used in a template for our Jenkins Builder as part of an ansible play. Most of these variables are also carried over to docs.linuxserver.io

Fixing typos or clarify the text in the readme

There are variables for multiple parts of the readme, the most common ones are:

Variable	Description
project_blurb	This is the short excerpt shown above the project logo.
app_setup_block	This is the text that shows up under "Application Setup" if enabled

Parameters

The compose and run examples are also generated from these variables.

We have a reference file in our Jenkins Builder.

These are prefixed with param_ for required parameters, or opt_param for optional parameters, except for cap_add. Remember to enable param, if currently disabled. This differs between parameters, and can be seen in the reference file.

Devices, environment variables, ports and volumes expects its variables in a certain way.

Devices

param_devices:
  - { device_path: "/dev/dri", device_host_path: "/dev/dri", desc: "For hardware transcoding" }
opt_param_devices:
  - { device_path: "/dev/dri", device_host_path: "/dev/dri", desc: "For hardware transcoding" }

Environment variables

param_env_vars:
  - { env_var: "TZ", env_value: "Europe/London", desc: "Specify a timezone to use EG Europe/London." }
opt_param_env_vars:
  - { env_var: "VERSION", env_value: "latest", desc: "Supported values are LATEST, PLEXPASS or a specific version number." }

Ports

param_ports:
  - { external_port: "80", internal_port: "80", port_desc: "Application WebUI" }
opt_param_ports:
  - { external_port: "80", internal_port: "80", port_desc: "Application WebUI" }

Volumes

param_volumes:
  - { vol_path: "/config", vol_host_path: "</path/to/appdata/config>", desc: "Configuration files." }
opt_param_volumes:
  - { vol_path: "/config", vol_host_path: "</path/to/appdata/config>", desc: "Configuration files." }

Testing template changes

After you make any changes to the templates, you can use our Jenkins Builder to have the files updated from the modified templates. Please use the command found under Running Locally on this page to generate them prior to submitting a PR.

Dockerfiles

We use multiple Dockerfiles in our repos, this is because sometimes some CPU architectures needs different packages to work. If you are proposing additional packages to be added, ensure that you added the packages to all the Dockerfiles in alphabetical order.

Testing your changes

git clone https://github.com/linuxserver/docker-plex.git
cd docker-plex
docker build \
  --no-cache \
  --pull \
  -t linuxserver/plex: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.

Update the chagelog

If you are modifying the Dockerfiles or any of the startup scripts in root, add an entry to the changelog

changelogs:
  - { date: "DD.MM.YY:", desc: "Added some love to templates" }
