Instances of a Cluster

Version: 17.07

Supported Since: 17.01

IPS provides a comprehensive view of the instances running inside a cluster. You can observe the status and health of those instances by going to the Instances tab of the Cluster Detail view. The resulting view lists all pods of the current cluster, including those belonging to previous deployments of the cluster (if they are still in Terminating state).

For an ESB instance within IPS might have several states

  • Running: Instance is healthy and running

  • Pending: Waiting to acquire resources in IPS platform to start deployment

  • Container Creating: Creating the instance

  • Crash Loop BackOff: Failed to start the instance, with repeated previous failures - something is wrong

  • Image Pull BackOff: Failed to create the container with provided UltraESB Docker Image

Clicking Details button against an instance will open a detailed view of it.

  • General tab in the detailed view displays metadata of the instance:
