Available versions

Available versions can be located by visiting Quay Container Repository.

Fetch image

BUILDER_VERSION=centos-7
docker pull quay.io/abn/rpmbuilder:${BUILDER_VERSION}

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.

Configuration

The following configurations are available via environment variables

Variable Description
SOURCES Configure source directory on the container file system
OUTPUT Configure output directory on the container file system
RPM_LINT If set, enables rpm linting once rpms are built
ARCH Target architecture to build the rpm for, defaults to x86_64

Volumes
