|
|
| `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
|
|
|
|
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](https://github.com/linuxserver/docker-hometown/edit/main/readme-vars.yml).
|
|
|
|
These variables are used in a template for our [Jenkins Builder](https://github.com/linuxserver/docker-jenkins-builder) as part of an ansible play.
|
|
Most of these variables are also carried over to [docs.linuxserver.io](https://docs.linuxserver.io/images/docker-hometown)
|
|
|
|
### 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](https://github.com/linuxserver/docker-jenkins-builder/blob/master/vars/_container-vars-blank) 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
|
|
|
|
```yml
|
|
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
|
|
|
|
```yml
|
|
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
|
|
|
|
```yml
|
|
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
|
|
|
|
```yml
|
|
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](https://github.com/linuxserver/docker-jenkins-builder) to have the files updated from the modified templates. Please use the command found under `Running Locally` [on this page](https://github.com/linuxserver/docker-jenkins-builder/blob/master/README.md) 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
|
|
|
|
```bash
|
|
git clone https://github.com/linuxserver/docker-hometown.git
|
|
cd docker-hometown
|
|
docker build \
|
|
--no-cache \
|
|
--pull \
|
|
-t linuxserver/hometown:latest .
|
|
```
|
|
|
|
The ARM variants can be built on x86_64 hardware using `multiarch/qemu-user-static`
|
|
|
|
```bash
|
|
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 changelog
|
|
|
|
If you are modifying the Dockerfiles or any of the startup scripts in [root](https://github.com/linuxserver/docker-hometown/tree/main/root), add an entry to the changelog
|
|
|
|
```yml
|
|
changelogs:
|
|
- { date: "DD.MM.YY:", desc: "Added some love to templates" }
|
