This commit implements the `manifest` command for `image-builder`.
It will generate an osbuild manifest based on the given inputs,
e.g.:
```
$ ./image-builder manifest centos-9 qcow2
{"version":"2","pipelines":[{"name":"build","runner":",...
```
Note that there is an integration test but because of the depsolve
it will be slow. It will be skipped when doing `go test -short`.
This commit adds a new generic `manifestgen` package that can be
used to generate osbuild manifests. It works on a higher level
then the low-level `manifest` package from `images` and provides
plugable resolvers and a streamlined API.
This package is meant to be moved to the `images` library eventually.
This commit adds a basic HACKING.md that explains the bare mimimum
to get started, including `go test -short` to skip the expensive
tests.
Contains also a drive-by rename of the test dependency install
for the GH action.
This commit adds a helper to find exactly a single image from a
given disto/type/arch description. This will be used in `manifest`,
`build` and potentially more. It is meant to support copy/paste
from the `image-builder list-images` output, so: "distro:centos-9"
is support just like "centos-9" (same for distro/imgType/arch).
This commit adds a `--datadir` override that allows overriding
the default search paths for e.g. the custom repositories. In
practise only repository overrides are supported because that
is the only data stored there.
This commit adds the new `image-builder` binary. This binary is
meant to build images from the CLI without the need to setup a
daemon. The main use-case is CI/CD and admins running this in
scripts or ad-hoc. The CLI should be pleasant to use.
This first commit adds the `list-images` command which is a thin
wrapper around functionality from the `osbuild/images` library.
It will list all buildable images by default and can be trimmed
down further via `--filter` which supports the filtering from
the `images` library, see https://github.com/osbuild/images/pull/1015
It also supports `--output` which will output the result in the
given format. Currently "text" and "json" are supported.
Note that this will not work on it's own yet, it will need an
installed image-builder to get the repositories. This will need
to get fixed via either:
1. a dependency package for `ibuilder` that carries all the repos
2. a shared repo that contains the repos
3. using go:embed to get them (see images#1038)
