Building the docker image requires the use of Docker BuiltKit. This is to allow the GITHUB_ACCESS_TOKEN
secret during the build phase.
For example, if the GITHUB_ACCESS_TOKEN
file contains the GitHub access token the container can be built using:
DOCKER_BUILDKIT=1 docker build . -t josephduffy:latest --secret=id=GITHUB_ACCESS_TOKEN,src=./GITHUB_ACCESS_TOKEN
