rpmbuild containers for RedHat-based various distros

CI Docker Pulls

This is different from upstream because:

  • it allows for faster-failed builds: a failed build can be detected early through building SRPM first, as well as optional rpmlint checks. In the upstream docker image, a failed build will have an exit status code of 0, so CI tools will not be able to detect failed builds to begin with.
  • a patch is applied to yum-builddep to prevent unnecessary enablement of -source repos, to facilitate faster builds. , the patch for yum-builddep to NOT enable source repos if .spec file is used (fixes a bug)

Available versions

Available versions can be located by visiting Docker Hub Repository.

Fetch image

For example, to use RHEL-7-based image:

BUILDER_VERSION=el7
docker pull getpagespeed/rpmbuilder:${BUILDER_VERSION}

Most images are tagged with the dist RPM tag, so you can use el7, el8, fc38 etc.

Run

In this example SOURCE_DIR contains the .spec file and sources for the RPM we are building.

# set env variables for convenience
SOURCE_DIR=$(pwd)/sources
OUTPUT_DIR=$(pwd)/output

# create a output directory
mkdir -p ${OUTPUT_DIR}

# make SELinux happy
chcon -Rt svirt_sandbox_file_t ${OUTPUT_DIR} ${SOURCE_DIR}

# build rpm
docker run -v ${SOURCE_DIR}:/sources -v ${OUTPUT_DIR}:/output getpagespeed/rpmbuilder:${BUILDER_VERSION}

The output files will be available in OUTPUT_DIR.

Custom run

  • You may pass RPMLINT=1 for failing on rpmlint checks (pedantic way of producing quality RPMs)
  • You may pass SRPM_ONLY=1 for only fast checks of particular file's build-ability

Debugging

If you are creating a spec file, it is often useful to have a clean room debugging environment. You can achieve this by using the following command.

docker run --rm -it --entrypoint bash \
    -v ${SOURCE_DIR}:/sources \
    -v ${OUTPUT_DIR}:/output \
    getpagespeed/rpmbuilder:${BUILDER_VERSION}

This command will drop you into a bash shell within the container. From here, you can execute build to build the spec file. You can also iteratively modify the specfile and re-run build.

Volumes

The following volumes can be mounted from the host.

Volume Description
/sources Source to build RPM from
/output Output directory where all built RPMs and SRPMs are extracted to
/root/rpmbuild rpmbuild directory for debugging etc
