How to Use Dockerfiles

GitHub actions are triggered for each new tag created in this repository to automatically build images from these Dockerfiles and push them to DockerHub repositories. These images form the basis of additional Dockerfiles in the other METplus component repositories for their compilation and/or testing.

1. Dockerfile defines the base compilation environment for MET. Tagged versions are available in the dtcenter/met-base DockerHub repository. It can be built manually by running:

docker build -t dtcenter/met-base:v2.0_debian10 -f Dockerfile.debian .
docker push dtcenter/met-base:v2.0_debian10

2. Dockerfile.unit_test_env extends the dtcenter/met-base image by adding packages required for running the MET unit tests. Tagged versions are available in the dtcenter/met-base-unit-test DockerHub repository. It can be built manually by running:

export MET_BASE_TAG=v2.0_debian10
docker build -t dtcenter/met-base-unit-test:v2.0_debian10 \
  --build-arg MET_BASE_TAG \
  -f Dockerfile.debian_unit_test_env .
docker push dtcenter/met-base-unit-test:v2.0_debian10

where:

• ${MET_BASE_TAG} is the version of dtcenter/met-base to be used
