How To Check Shield Status¶

To check Shield system status, open Rancher and go to the cluster and select the Default option.

Under Workloads, all namespaces and their deployments are displayed, each with a visual status indicator (green indicator = Healthy).

It is possible to sort the list by State and then easily see if there are unhealthy deployments.

To fix this issue, select the unhealthy deployments and choose the Redeploy option.

If this option does not result as expected (some issues still remain), try the following:

Some containers may be in Waiting mode, but without any Events or Logs. To solve this situation - restart the cluster management machines using:

sudo reboot
