Automated Docker releases using Maven and GitHub Actions

Life is too short for tedious, manual release processes.

Here, we will use Maven's [Release plugin][maven-release] to execute releases. Instead of triggering the release process manually, we will use a [GitHub Actions][gh-actions] workflow on the master branch. All development work is done on the dev branch (or feature branches) and a release is done when (and only when) the dev branch is merged with the master branch.

Mixing two frameworks will typically require that you are an expert in both to be successful. This is because making them interact will add an additional level of complexity of having to interopate between the two frameworks. That often requires detailed knowledge of the internal workings of the frameworks that you would normally just "take for granted" such as session management and caching.

The point of using a framework is that it provides out-of-the-box "known good practice" in many low-level details so you can focus on your "business logic" not the "basic plumbing". The moment you "go against the framework" and try to do complex things like "make two frameworks coexist" you are basically throwing away the main benefit of using any framework. In short, using two is likely not better than using one. It is like to be more of a case that using two will be "three times the work".

While the actual result will depend on lots of factors I would expect that you would be better off if you picked the worst fra

How To

Install bashdb which you can do from source or get from a package manager. On MacOS you can brew install bashdb.

Install Visual Studio Code and the Bash Debug plugin from the marketplace. See this blog article yet I didn't have to do any upgrades of build from source things worked pretty much out of the box after installing bashdb via Homebrew.

Use the debug.sh script in this gist as the entrypoint to be able to step through code.
