Manage policies with YAML
Manage policies with YAML
This section describes how to use YAML to manage existing policies in the following ways:
- Change which policy manages a workload
- Stop optimization of a workload
There is also a table of common kubectl commands.
Change which policy manages a workload
To change the policy that manages a workload, edit the policy selectors on the current and the desired policy.
Tip
To avoid an unmanaged gap, add the workload to the new policy before removing it from the old policy.
Stop optimization of a workload
To stop optimizing a workload, remove the workload from policy selection, using the relevant solution:
- Remove it from the policy’s
appListselector. - Update the policy label selector so it no longer matches the workload.
- Remove the policy annotation from the workload.
After removing, the workload may still be managed if it matches a different policy.
Common kubectl commands
Replace the values inside [ ] with your values.
CRDs
- Pod rightsizing:
policies.rightsizing.kompass.zesty.co - Replica optimization:
policies.horizontalscaling.kompass.zesty.co
Annotations
- Pod rightsizing:
rightsizing.kompass.zesty.co/policy: <any rightsizing policy> - Replica optimization:
horizontalscaling.kompass.zesty.co/policy: <any rightsizing policy>
| To do this | Use this command |
|---|---|
| List policies | kubectl get [policy-crd] |
| View a policy manifest | kubectl get [policy-crd] [policy-name] -o yaml |
| Create or update a policy | kubectl apply -f [policy-file].yaml |
| Add or update the workload policy annotation | kubectl annotate [workload-kind]/[workload-name] -n [namespace] [policy-annotation-key]=[policy-name] --overwrite |
| Remove the workload policy annotation | kubectl annotate [workload-kind]/[workload-name] -n [namespace] [policy-annotation-key]- |
| Delete a custom policy | kubectl delete [policy-crd] [policy-name] |
