Check also further docker configuration options: 'cgroup-driver', ... + - Integrate fast Ethernet and use conteiner native networking. OpenVSwitch is slow and causes problems. + - Do not run pods on Master nodes, but Gluster and a few databases pods (MySQL) are OK (multiple reasons, especially mounting a lot of Gluster Volumes) + - Object Storage should be integrated, either Gluster Block is ready for production or we have to use Ceph as well + - Automatic provisioning would be much better then handling volumes trough Ands. Basically, this will render Ands redundant. We can switch to Helm, etc. + But, we need ability to easily understand which volume belong to which pod/namespace and automatically kill redundant volumes. + +Questions +========= + - Updates to cluster configuration (evaluate current load, etc.)? Non-scheduling masters? Something with storage? Specify appropriate node parameters + - Shall we switch to plain Kubernetes or keep using OpenShift.
