Bear in mind that a container is not exactly the same as a full OS installation, unless you make it so. This can lead to surprising problems.

One issue that I have seen is that installations fail when using a CentOS 7 container with an error that gzip is not found -- even though gzip is installed.

If you encounter this, make sure that the 'which' command is installed in the container. The installation tool uses which to locate gzip.

yum install -y which

This may prevent an annoying issue when you are commissioning a new container.
