# Build new image

As an example we build a new version of the `leap:jessie` base image:

    REGISTRY="0xacab.org:4567"
    REGISTRY_PATH="${REGISTRY}/leap/gitlab-buildpackage"
    IMAGE='jessie_amd64'

    cd $IMAGE
    docker ${DOCKER_OPTS} build ${DOCKER_BUILD_OPTS} -t ${REGISTRY_PATH}:${IMAGE} .

## Package upgrades

Sometimes you need to upgrade packages in the base image,
so this is not done on every build, i.e. when security updates
are available.
Disable caching and build new images with:

    export DOCKER_BUILD_OPTS="--no-cache"

## Push images

    docker login --username=varac 0xacab.org:4567
    docker ${DOCKER_OPTS} push ${REGISTRY_PATH}:${IMAGE}
