    what is the difference between management node and worker node?

    Is management node for Docker management platform (like k8s or Mesos)?

    Is it necessary to add more management nodes and how?

      what is the difference between management node and worker node?

      Management node is for orchestration purposes and the worker nodes are where your Docker containers actually run

      Is management node for Docker management platform (like k8s or Mesos)?

      Sort of.. management node has the necessary components for orchestrating the Docker containers which run on the worker nodes

      Is it necessary to add more management nodes and how?

      Not as of now. Each OCC instance has ONE management node and one or more worker nodes

      Understood, Thanks for your reply.I am new to oracle container service. 

      But in Mesos or K8S, there are usually 3 master nodes to ensure the reliability. I think there may be an option like " HA model"

      On the other hand, I believe if too many woker nodes added and too many dockers run, one management node (with only one OCPU) may not handle the pressure.
