By nature containers do not have persistent storage. Their data is lost when a container exits. We have implemented a Ceph cluster for a place to put data that should be saved. Typical use case for persisitent storage would be something like a mysql database so data is kept. Primarily we are using ceph block devices formatted as xfs(for wide range of compatibility/performance) that OpenShift can attach to a container anywhere in its filesystem. For a quick intro to Ceph and common cli commands, check out CEPH.md. For a demo on how to provision a ceph block device manually and add it to Openshift for use with your project, check out examples/ceph-volume/HOWTO_CEPH_BLOCK_DEVICES.md
When running Java based services in a container you may want to set this environment variable if your memory usage is erratic: MALLOC_ARENA_MAX=4 This effect is particularly pronounced when running on a large production machine where there are a lot of processors and RAM. You can read more about what is going on on in this github issue. Also this blog describes exactly what these mysterious thread arena contraptions are.
