As DBAs, one of the tasks that we do on a fairly regular basis is install new Db2 code on the database server. Although it can become routine, installing new code on a server can be surprisingly complex. Docker provides a simple alternative.
If you are a serious Db2 user, chances are you have downloaded and used free Db2 versions for a few years. Db2 Express-C was a free way to learn Db2 on Linux, Unix and Windows, to practise and test your SQL skills and in later versions implement or ship Db2 with your small production application.
