Pod Security Policies

note

These cluster options are only available for clusters in which Rancher has launched Kubernetes.

You can always assign a pod security policy (PSP) to an existing project if you didn’t assign one during creation.

Prerequisites

• Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see Creating Pod Security Policies.
• Assign a default Pod Security Policy to the project’s cluster. You can’t assign a PSP to a project until one is already applied to the cluster. For more information, see the documentation about adding a pod security policy to a cluster.

Applying a Pod Security Policy

1. In the upper left corner, click ☰ > Cluster Management.
2. On the Clusters page, go to the cluster where you want to move a namespace and click Explore.
3. Click Cluster > Projects/Namespaces.
4. Find the project that you want to add a PSP to. From that project, select ⋮ > Edit Config.
5. From the Pod Security Policy drop-down, select the PSP you want to apply to the project. Assigning a PSP to a project will:

• Override the cluster’s default PSP.
• Apply the PSP to the project.
• Apply the PSP to any namespaces you add to the project later.

1. Click Save.

Result: The PSP is applied to the project and any namespaces added to the project.

note

Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
