Description:
It was discovered in an OpenShift Cluster deployed into AWS that the AWS NVME disk order changes after reboot in the Red Hat Enterprise Linux 7 operating system. This impacts docker's storage configuration negatively if you have multiple disks configured. This repo contains two basic playbooks that address the two core use cases.
If you are configuring docker storage for the first time:
ocp-aws-nvme-docker-preinstall.yml
If you have already configured docker storage, disks have changed order, and you need to fix dockers configuration in order to bring up the service:
ocp-aws-nvme-docker-preinstall-fix.yml
