Docker Course Labs

Lab Solution

The second part of the GitHub build uses the latest Docker Compose file:

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. 21.05-57 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.

Back to the exercises.
