This runs two containers from official images. It installs OPA after the containers have started. It is useful for testing the OPA installer on Oracle supported deployments (Oracle JRE, Weblogic, and MySQL).
This is a completely unsupported configuration (OpenJDK, Tomcat, and MySQL) but is much faster since it builds streamlined images with OPA pre-installed. This can be useful for developers who want a local Hub install but with a smaller footprint than a VM.
And finally if you want a quick and easy OPA Hub but prefer virtual machines, here's a minimal-effort script for creating an OPA Hub on VirtualBox. This, like the Tomcat Docker config, is not supported, but is quick and easy for dev use.
