[wildfly-dev] Creating a Keycloak Feature Pack

Perhaps it's a little early to start implementing a Keycloak FP, but I'm
starting to look at it and identify potential issues. So I thought I
should list the issues here and find out which ones are already
addressed and which need some time to work out.
*Task:* Implement a feature pack that adds the Keycloak Auth Server to
either/both of the _WildFly Web build_ and the _WildFly Full build_.
Note that this is completely separate from the effort to use Keycloak to
secure the web console. That only involves Keycloak adapter integration
destined to ride on top of Elytron.
Here, we are talking about using a feature pack to add and configure the
Keycloak Auth Server.
*Issue #1: Module duplication.* Keycloak needs to install the
bouncycastle module. This module already exists in the full build but
not the web build. So you have the same module specified for the
Keycloak FP and the Full WildFly FP.
I assume this is already handled? Will the FP mechanism have a problem
with duplication of modules when I try to add a module to full that
*Issue #2: Adding a subsystem:* It looks like the current mechanism for
creating configuration files is inappropriate for the Keycloak FP. The
way this is done right now is that a config file is generated via the
combination of a template file and a list of subsystem snippets. So you
would have, for example:
template-keycloak.xml + subsystems-keycloak.xml = standalone-keycloak.xml
But that's not what we really want. We don't want a separate
standalone-keycloak.xml. We really just want to add the keycloak
subssytem to every generated config file, whatever they may be.
*Issue #3: Adding a deployment:* The Keycloak auth server is deployed
as a WAR. We can use the copy-artifacts mechanism to simply copy the
WAR into the deployments directory. But that doesn't work for a domain
where you want to have the WAR pre-loaded into the content repository.
Furthermore, it's probably not the best way to integrate this for
What would be a better option?
