ansible-firewalld

Running ansible in a container build for firewalling

In this example, we:

• Derive from the base image
• Install ansible
• Inject a playbook into the image
• Run ansible as part of the build, using the upstream firewalld task
• Remove ansible (we don't need it at runtime)

There's nothing really specific to firewalling here; this example can be used as a reference for executing any arbitrary ansible playbook as part of a container image build.
