Dockerfile.jenkins-build

# This is a docker container image to build SUMO
# on the Jenkins CI infrastructure at Eclipse
# (see https://ci.eclipse.org)
#
# It is necessary to build a custom ubuntu image
# since the containers at Eclipse are run without
# root privilege, so we cannot install any packages
# at build time.

# The docker image should be uploaded to ghcr.io
# in order to be used by the Jenkinsfile build.
# This can be achieved with a Personal Access Token.

# 1) IMAGE BUILDING
#
# Build image while being in the repository top folder:
# > docker build \
#    -f build_config/docker/Dockerfile.jenkins-build \
#    -t ghcr.io/eclipse/eclipse-sumo-build-ubuntu:latest \
#    .
#
# OR: Build a multi-architecture image (amd64 + arm64):
# > docker buildx build \
#     --platform linux/amd64,linux/arm64 \
#     -f build_config/docker/Dockerfile.jenkins-build \
#     -t ghcr.io/eclipse/eclipse-sumo-build-ubuntu:latest \
#     .

# 2) IMAGE PUSH TO GHCR REGISTRY
#
# See the following script for a developer with username USERNAME on GitHub
# and a Personal Access Token from GitHub contained in Env-variable GITHUB_PAT:
#
# > echo $GITHUB_PAT | docker login ghcr.io --username USERNAME --password-stdin
#
# > docker push ghcr.io/eclipse/eclipse-sumo-build-ubuntu:latest

# The ubuntu:latest tag points to the "latest LTS"
