# Bulid Container Installer Action
|
|
This action is used to generate an ISO for installing OSTrees stored in a container. This utilizes the anaconda command `ostreecontainer`
|
|
|
|
## Makefile
|
|
A Makefile is provided for ease of use. There are separate targets for each file generated, however `make` can be used to generate the final image and `make clean` can be used to clean up the workspace. The resulting ISO will be stored in the `build` directory.
|
|
|
|
See [Customizing](#customizing) for information about customizing the image that gets created.
|
|
|
|
## Container
|
|
A container with the necessary tools already installed is provided at `ghcr.io/jasonn3/build-container-installer:latest`
|
|
|
|
To use the container file, run `docker run --privileged --volume .:/build-container-installer/build ghcr.io/jasonn3/build-container-installer:latest`.
|
|
|
|
This will create an ISO with the baked in defaults of the container image.
|
|
|
|
See [Customizing](#customizing) for information about customizing the image that gets created. The variable can either be defined as environment variables or as command arguments.
|
|
Examples:
|
|
|
|
Building an ISO to install Fedora 38
|
|
```bash
|
|
docker run --rm --privileged --volume .:/build-container-installer/build -e VERSION=38 -e IMAGE_NAME=base -e IMAGE_TAG=38 -e VARIANT=Server ghcr.io/jasonn3/build-container-installer:latest
|
|
```
|
|
|
|
Building an ISO to install Fedora 39
|
|
```bash
|
|
docker run --rm --privileged --volume .:/build-container-installer/build -e VERSION=39 -e IMAGE_NAME=base -e IMAGE_TAG=39 -e VARIANT=Server ghcr.io/jasonn3/build-container-installer:latest
|
|
```
|
|
|
|
## Customizing
|
|
The following variables can be used to customize the create image.
|
|
|
|
| Variable | Description | Default Value |
|
|
| ----------------- | -------------------------------------------------------- | ------------------------------ |
|
|
| ARCH | Architecture for image to build | x86_64 |
|
|
| VERSION | Fedora version of installer to build | 39 |
|
|
| IMAGE_REPO | Repository containing the source container image | quay.io/fedora-ostree-desktops |
|
|
| IMAGE_NAME | Name of the source container image | base |
|
|
| IMAGE_TAG | Tag of the source container image | *VERSION* |
|
|
| EXTRA_BOOT_PARAMS | Extra params used by grub to boot the anaconda installer | \[empty\] |
|
|
| VARIANT | Source container variant\* | Server |
|
|
| WEB_UI | Enable Anaconda WebUI (experimental) | false |
|
|
|
|
Available options for VARIANT can be found by running `dnf provides system-release`.
|
|
Variant will be the third item in the package name. Example: `fedora-release-kinoite-39-34.noarch` will be kinoite
|

## VSCode Dev Container
|
|
There is a dev container configuration provided for development. By default it will use the existing container image available at `ghcr.io/jasonn3/build-container-installer:latest`, however, you can have it build a new image by editing `.devcontainer/devcontainer.json` and replacing `image` with `build`. `Ctrl+/` can be used to comment and uncomment blocks of code within VSCode.
|
|
|
|
The code from VSCode will be available at `/workspaces/build-container-installer` once the container has started.
|
|
|
|
Privileged is required for access to loop devices for lorax.
|
|
|
|
Use existing image
|
|
```json
|
|
{
|
|
"name": "Existing Dockerfile",
|
|
// "build": {
|
|
// "context": "..",
|
|
// "dockerfile": "../Dockerfile",
|
|
// "args": {
|
|
// "version": "39"
|

// }
|
|
// },
|
|
"image": "ghcr.io/jasonn3/build-container-installer:latest",
|
|
"overrideCommand": true,
|
|
"shutdownAction": "stopContainer",
|
|
"privileged": true
|
|
}
|
|
```
|
|
|
|
Build a new image
|
|
```json
|
|
{
