Running RHQ in a Docker container

November 22, 2014

The following Dockerfile can be used to run RHQ 4.12 in a Docker container. Please note that the setup is not suitable for production use; it is primarily designed to quickly provision an RHQ test instance. The RHQ instance listens on port 7080 and the default login is rhqadmin/rhqadmin.
