[FEATURE] Support `--jobs N` flag on buildah bud #115

Open anthr76 opened 1 year ago

anthr76 commented 1 year ago

Is your feature request related to a problem? Please describe.

In order to possibly speed up builds support the --jobs argument

Describe the solution you'd like

--jobs N

Run up to N concurrent stages in parallel. If the number of jobs is greater than 1, stdin will be read from /dev/null. If 0 is specified, then there is no limit on the number of jobs that run in parallel.

REF: https://github.com/containers/buildah/blob/main/docs/buildah-build.1.md

Describe alternatives you've considered

Additional context

This can help to greatly reduce build times for large multi-arch builds.

+1, for some reason adding as extra args seems to be ignored
