Role management provides Ops features at both the service level and specific POD level, such as restart operations. POD health status monitoring is supported to understand the real-time status of role processes.
Directions
1. Log in to the EMR on TKE Console and click the Cluster ID/Name in the cluster list to enter the cluster details page.
2. On the cluster details page, select Cluster Services and click the corresponding service to enter the Role Management page.
3. The Role List displays information such as the current service role’s POD health status, running/desired POD count, resource configuration, and latest restart time. The POD list displays information such as POD resource health status, POD status, POD IP, restart count, and latest restart time.
Description
When the POD status is Running or Succeeded, the POD health status is displayed as Normal; when the POD status is Pending, Failed, Unknown, or the corresponding service container is Not Ready, the POD health status is displayed as Abnormal.
