The second part of the GitHub build uses the
latest Docker Compose file:
RELEASEenvironment variable but not the
BUILD_NUMBERvariable the main Compose file uses
When you merge in the latest file it will build images with the tag
21.05, which is the version for this release of the app.
Consumers can use
21.05 to get the current build for this release, or e.g.
21.05-33 to get a specific build:
docker pull courselabs/rng-api:21.05 docker image ls courselabs/rng-api
Those two tags are aliases of the same image now, but with the next release the
21.05 tag will advance and will be an alias of the a later build.
