By default, +`bootc-image-builder` will build for the native host architecture. The target architecture +must match an available architecture of the `bootc-image-builder` image you are using to build the disk image. +Navigate to the [centos-image-builder repository tags page](https://quay.io/repository/centos-bootc/bootc-image-builder?tab=tags) +and hover over the Tux icons to see the supported target architectures. +The architecture of the bootc OCI image and the bootc-image-builder image must match. For example, when building +a non-native architecture bootc OCI image, say, building for x86_64 from an arm-based Mac, it is possible to run +`podman build` with the `--platform linux/amd64` flag. In this case, to then build a disk image from the same arm-based Mac, +you should provide `--target-arch amd64` when running the `bootc-image-builder` command. + +## Progress types + +The following progress types are supported: + +* verbose: No spinners or progress bar, just information and full osbuild output +* term: Terminal based output, spinner, progressbar and most details of osbuild are hidden +* debug: Details how the progress is called, mostly useful for bugreports + +Note that when no value is given the progress is auto-detected baed on the environment.

The config file is mapped into the container directory to `/config.toml`. The customizations are specified under a `customizations` object. + +As an example, let's show how you can add a user to the image: + +Firstly create a file `./config.toml` and put the following content into it: + +```toml +[[customizations.user]] +name = "alice" +password = "bob" +key = "ssh-rsa AAA ... user@email.com" +groups = ["wheel"] +``` + +Then, run `bootc-image-builder` with the following arguments: + +```bash +sudo podman run \ + --rm \ + -it \ + --privileged \ + --pull=newer \ + --security-opt label=type:unconfined_t \ + -v ./config.toml:/config.toml:ro \ + -v ./output:/output \ + -v /var/lib/containers/storage:/var/lib/containers/storage \ + quay.io/centos-bootc/bootc-image-builder:latest \ + --type qcow2 \ + quay.io/centos-bootc/centos-bootc:stream9 +``` + +The configuration can also be passed in via stdin when `--config -` +is used. Only JSON configuration is supported in this mode. + +Additionally, images can embed a build config file, either as +`config.json` or `config.toml` in the `/usr/lib/bootc-image-builder` +directory.

See the see [Detailed description of optional flags](#detailed-description-of-optional-flags). + + +#### Allowed mountpoints and sizes + +The following restrictions and rules apply, unless the rootfs is `btrfs`: +- `/` can be specified to set the desired (minimum) size of the root filesystem. The final size of the filesystem, mounted at `/sysroot` on a booted system, is the value specified in this configuration or 2x the size of the base container, whichever is largest. +- `/boot`can be specified to set the desired size of the boot partition. +- Subdirectories of `/var` are supported, but symlinks in `/var` are not. For example, `/var/home` and `/var/run` are symlinks and cannot be filesystems on their own. +- `/var` itself cannot be a mountpoint. + +The `rootfs` option (or source container config, see [Detailed description of optional flags](#detailed-description-of-optional-flags) section) defines the filesystem type for the root filesystem. Currently, creation of btrfs subvolumes at build time is not supported. Therefore, if the `rootfs` is `btrfs`, no custom mountpoints are supported under `/var`. Only `/` and `/boot` can be configured. + + +### Anaconda ISO (installer) options (`installer`, mapping) + +Users can include kickstart file content that will be added to an ISO build to configure the installation process. When using custom kickstart scripts the customization needs to be done via the custom kickstart script. For example using a `[customizations.user]` block alongside a `[customizations.installer.kickstart]` block is not supported. See this issue [https://github.com/osbuild/bootc-image-builder/issues/528] for additional detail. + +Since multi-line strings are difficult to write and read in json, it's easier to use the toml format when adding kickstart contents: + +```toml +[customizations.installer.kickstart] +contents = """ +text --non-interactive +zerombr +clearpart --all --initlabel --disklabel=gpt +autopart --noswap --type=lvm +network --bootproto=dhcp --device=link --activate --onboot=on +""" +``` + +The equivalent in json would be: +```json +{ + "customizations": { + "installer": { + "kickstart": { + "contents": "text --non-interactive\nzerombr\nclearpart --all --initlabel --disklabel=gpt\nautopart --noswap --type=lvm\nnetwork --bootproto=dhcp --device=link --activate --onboot=on" + } + } + } +} +``` + +Note that bootc-image-builder will automatically add the command that installs the container image (`ostreecontainer ...`), so this line or any line that conflicts with it should not be included. See the relevant [Kickstart documentation](https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#ostreecontainer) for more information. +No other kickstart commands are added by bootc-image-builder in this case, so it is the responsibility of the user to provide all other commands (for example, for partitioning, network, language, etc). + +#### Anaconda ISO (installer) Modules + +The Anaconda installer can be configured by enabling or disabling its dbus modules. + +```toml +[customizations.installer.modules] +enable = [ + "org.fedoraproject.Anaconda.Modules.Localization" +] +disable = [ + "org.fedoraproject.Anaconda.Modules.Users" +] +``` + +```json +{ + "customizations": { + "installer": { + "modules": { + "enable": [ + "org.fedoraproject.Anaconda.Modules.Localization" + ], + "disable": [ + "org.fedoraproject.Anaconda.Modules.Users" + ] + } + } + } +} +``` + +The following module names are known and supported: +- `org.fedoraproject.Anaconda.Modules.Localization` +- `org.fedoraproject.Anaconda.Modules.Network` +- `org.fedoraproject.Anaconda.Modules.Payloads` +- `org.fedoraproject.Anaconda.Modules.Runtime` +- `org.fedoraproject.Anaconda.Modules.Security` +- `org.fedoraproject.Anaconda.Modules.Services` +- `org.fedoraproject.Anaconda.Modules.Storage` +- `org.fedoraproject.Anaconda.Modules.Subscription` +- `org.fedoraproject.Anaconda.Modules.Timezone` +- `org.fedoraproject.Anaconda.Modules.Users` + +*Note: The values are not validated.
