|
||
## 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](https://github.com/linuxserver/docker-fail2ban/edit/master/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-fail2ban) | ||
|
||
### 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-fail2ban.git | ||
cd docker-fail2ban | ||
docker build \ | ||
--no-cache \ | ||
--pull \ | ||
-t linuxserver/fail2ban: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-fail2ban/tree/master/root), add an entry to the changelog | ||
|
||
```yml | ||
changelogs: | ||
- { date: "DD.MM.YY:", desc: "Added some love to templates" } | ||
``` |
