This commit adds an initial Containerfile to build an `image-builder` container. Use all the DNF commands together and add a cleaning command to the end of it. This makes fewer layers and keeps the image size slightly smaller. Co-authored-by: Simon de Vlieger <supakeen@redhat.com> Signed-off-by: Simon de Vlieger <supakeen@redhat.com>

# image-builder CLI
|
|
|
|
Build images from the commandline in a convenient way.
|
|
|
|
## Run via container
|
|
|
|
```console
|
|
$ sudo podman run --privileged \
|
|
-v ./output:/output \
|
|
ghcr.io/osbuild/image-builder-cli:latest \
|
|
build \
|
|
--distro fedora-41 \
|
|
minimal-raw
|
|
```
|
|
|
|
## Installation
|
|
|
|
This project is under development right now and needs to be run via:
|
|
```console
|
|
$ go run github.com/osbuild/image-builder-cli/cmd/image-builder@main
|
|
```
|
|
or install it into $GOPATH/bin
|
|
```console
|
|
$ go install github.com/osbuild/image-builder-cli/cmd/image-builder@main
|
|
```
|
|
|
|
we plan to provide rpm packages as well.
|
|
|
|
|
|
## Prerequisites
|
|
|
|
Make sure to have the required `osbuild` rpms installed:
|
|
```console
|
|
$ sudo dnf install osbuild osbuild-depsolve-dnf osbuild-composer
|
|
```
|
|
(`osbuild-composer` is only needed to get the repository definitions
|
|
and this dependency will go away soon).
|
|
|
|
## Examples
|
|
|
|
To see the list of buildable images run:
|
|
```console
|
|
$ image-builder list-images
|
|
...
|
|
centos-9 type:qcow2 arch:x86_64
|
|
...
|
|
rhel-10.0 type:ami arch:x86_64
|
|
...
|
|
```
|
|
|
|
To actually build an image run:
|
|
```console
|
|
$ sudo image-builder build qcow2 --distro centos-9
|
|
...
|
|
```
|
|
this will create a directory `centos-9-qcow2-x86_64` under which the
|
|
output is stored.
|
|
|
|
|
|
It is possible to filter:
|
|
```console
|
|
$ image-builder list-images --filter ami
|
|
...
|
|
centos-9 type:ami arch:x86_64
|
|
...
|
|
rhel-8.5 type:ami arch:aarch64
|
|
...
|
|
rhel-10.0 type:ami arch:aarch64
|
|
```
|
|
or be more specific
|
|
```console
|
|
$ image-builder list-images --filter "arch:x86*" --filter "distro:*centos*"
|
|
centos-9 type:ami arch:x86_64
|
|
...
|
|
centos-9 type:qcow2 arch:x86_64
|
|
...
|
|
```
|
|
|
|
The following filters are currently supported, shell-style globbing is supported:
|
|
* distro: the distro name (e.g. fedora-41)
|
|
* arch: the architecture name (e.g. x86_64)
|
|
* type: the image type name (e.g. qcow2)
|
|
* bootmode: the bootmode (legacy, uefi, hybrid)
|
|
|
|
The output can also be switched, supported are "text", "json":
|
|
```console
|
|
$ image-builder list-images --output=json
|
|
[
|
|
{
|
|
"distro": {
|
|
"name": "centos-9"
|
|
},
|
|
"arch": {
|
|
"name": "aarch64"
|
|
},
|
|
"image_type": {
|
|
"name": "ami"
|
|
}
|
|
},
|
|
...
|
|
{
|
|
"distro": {
|
|
"name": "rhel-10.0"
|
|
},
|
|
"arch": {
|
|
"name": "x86_64"
|
|
},
|
|
"image_type": {
|
|
"name": "wsl"
|
|
}
|
|
}
|
|
]
|
|
|
|
```
|

## FAQ
|
|
|
|
Q: Does this require a backend.
|
|
A: The osbuild binary is used to actually build the images but beyond that
|
|
no setup is required, i.e. no daemons like osbuild-composer.
