Unable to access the PMK UI due to sunpike-kine issues

Problem

  • PMK UI is failing and getting stuck on Loading region data.

  • Not able to access the PMK clusters and hosts through UI.

Environment

  • Platform9 Managed Kubernetes - All Versions

Cause

  • The connection to MySQL (RDS) gets blocked due to connection errors observed by the Sunpike Kine service.

  • This is observed when there are frequent errors observed when clients try to connect to MySQL.

time="[Timestamp]" level=fatal msg="building kine: Error 1129: Host '[IP]' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'"

Resolution

  • Manually execute _**mysqladmin flush-hosts**_ command to unblock the connection from Sunpike to MySQL.

  • This is a known issue and is being tracked via JIRA internally.
