OpenLiberty Docker image with *all* features enabled

The OpenLiberty Docker Images tagged as full contain a server.xml that only enables the javaee-8.0 feature. Those tagged as microProfile3 only enable microProfile-3.0.

I want both... even better: I'd like to have just all features enabled while I'm developing; I'll optimize for performance when I need it, i.e. maybe not at all.

Is there an easier way than to build another image with both features enabled?

Solution

  • It isn't possible to enable all features at once in Liberty because many of the features intentionally conflict with one another. For example, you can't load two different versions of the same feature at the same time (e.g. servlet-3.1 and servlet-4.0)

    You can pretty concisely enable all of the latest JavaEE and MicroProfile features at once by doing this:

    <server>
  <featureManager>
    <feature>javaee-8.0</feature>
    <feature>microProfile-3.2</feature>
  </featureManager>
</server>

    Doing this will give quite a lot of capabilities (more than a single app typically needs). The features not included in these two umbrella features are pretty specialized, such as JCache session persistence (sessionCache-1.0) or event logging (eventLogging-1.0).
