build.yml

---
# This workflow will run on all pull-request branches and on 'master',
# 'staging', and 'trying'
#
# In all cases it will incrementally build: riotdocker-base, static-test-tools
# and riotbuild
#
# If riotbuild is successfully built then it will run a simple compile test on
# a subset of BOARDs using gcc and llvm
#
# On master if the building and testing succeeds it will push the generated image
# to ${DOCKER_REGISTRY}
#
# * Requirements:
#   * Add the following secrets:
#     * DOCKER_REGISTRY: the registry to pull and push images from/to
#     * DOCKERHUB_USERNAME: the Docker Hub username account that can
#       publish to ${DOCKER_REGISTRY}
#     * DOCKERHUB_TOKEN: the Docker Hub access token for ${DOCKERHUB_USERNAME}
