In the following OBS project config, pbuild does not automatically detect the presence of a Dockerfile.dapper file in the package source:
%if %_repository == "example-repo"
Type: docker
BuildEngine: docker
...
%endif
Although, changing Type: docker to Type: dapper makes OBS detect Dockerfile.dapper as the build recipe:
%if %_repository == "example-repo"
Type: dapper
BuildEngine: docker
...
%endif
This appears to work by accident, since Type: dapper is not a valid value.
I further tested with any random Type: abc which also made OBS pick up any file matching *.abc in the package source as a build recipe. This seems to be a bug or unintended behaviour.
The current implementation for finding the build recipe, (i) either via the configured Type: or (ii) via auto-detection - is present here and may require an update:
|
return $files{'Dockerfile'} if $type eq 'docker' && $files{'Dockerfile'}; |
|
return $files{'fissile.yml'} if $type eq 'fissile' && $files{'fissile.yml'}; |
|
return $files{'Chart.yaml'} if $type eq 'helm' && $files{'Chart.yaml'}; |
|
return (grep {/flatpak\.(?:ya?ml|json)$/} sort keys %files)[0] if $type eq 'flatpak'; |
|
return $files{'PKGBUILD'} if $type eq 'arch' && $files{'PKGBUILD'}; |
|
return $files{'APKBUILD'} if $type eq 'apk' && $files{'APKBUILD'}; |
|
my $pkg = $p->{'pkg'}; |
|
$pkg = $p->{'flavor'} if $p->{'flavor'}; |
|
return $files{"Dockerfile.$pkg"} if $type eq 'docker' && $files{"Dockerfile.$pkg"}; |
|
return $files{"$pkg.$type"} if $files{"$pkg.$type"}; |
|
# try again without last components |
|
return $files{"$1.$type"} if $pkg =~ /^(.*?)\./ && $files{"$1.$type"}; |
|
my @files = grep {/\.$type$/} keys %files; |
|
@files = grep {/^\Q$pkg\E/i} @files if @files > 1; |
|
return $files{$files[0]} if @files == 1; |
|
if (@files > 1) { |
|
@files = sort @files; |
|
return $files{$files[0]}; |
|
} |
|
return $files{'debian.control'} if $type eq 'dsc' && $files{'debian.control'}; |
|
return $files{'debian/control'} if $type eq 'dsc' && $files{'debian/control'}; |
|
# as last resort ignore the type for image/container building |
|
if ($type ne 'docker') { |
|
return $files{'Dockerfile'} if $files{'Dockerfile'}; |
|
return $files{"Dockerfile.$pkg"} if $files{"Dockerfile.$pkg"}; |
