release_docker.yaml

# When a new release is published,
# upload image to Dockerhub.
#
# Requires the following repository secrets:
# - DOCKER_IMAGE - Configured as a secret so it can be configured per fork.
# - DOCKER_HUB_USERNAME
# - DOCKER_HUB_ACCESS_TOKEN
# - GITHUBPAT - The github account to use for downloading CRAN dependencies.
#                      Needed to avoid "API rate limit exceeded" from github.
