Run

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

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

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

# build rpm
docker run --rm -it \
    -v ${SOURCE_DIR}:/sources:z \
    -v ${OUTPUT_DIR}:/output:z \
    -e OUTPUT_USER=$UID \
    quay.io/abn/rpmbuilder:${BUILDER_VERSION}

The output files will be available in OUTPUT_DIR.

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:z \
    -v ${OUTPUT_DIR}:/output:z \
    quay.io/abn/rpmbuilder:${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.
