Discussion

MKE and MSR are set to disallow administrators and users to schedule containers. This setting must be checked for allowing administrators or users to schedule containers may override essential settings, and therefore is not permitted.

Check Content

To ensure this setting has not been modified follow these steps on each node:

Log in to the MKE web UI and navigate to admin >> Admin Settings >> Orchestration. Scroll to down "Container Scheduling".

Verify that the "Allow administrators to deploy containers on MKE managers or nodes running MSR" is disabled. If it is checked (enabled), this is a finding.

Verify that the "Allow users to schedule on all nodes, including MKE managers and MSR nodes" is disabled. If it is checked (enabled), this is a finding.
