Security constraints

PreviousSetupNextRegistries

Was this helpful?

Pod security policies can be used to define under what conditions workloads can run. With Portainer we achieve this by leveraging via .

Policies are configured on a per-environment basis. To enable and configure security policies, from the menu select a Kubernetes environment, then expand Cluster and click Security constraints.

This is advanced functionality and should be applied with caution. If a deployment attempts to create a pod that does not meet defined security constraints it may not be immediately obvious that the constraint is the reason for provision failure.

Toggle on Enable pod security constraints to enable the functionality, then toggle on the features you require and configure them as needed.

Field/Option
Overview

Restrict running privileged containers

Set whether any container in a pod can enable privileged mode.

Restrict host namespace

Controls whether the pod containers can share the process ID namespace and host IPC namespace.

Restrict host networking ports

Define a range of ports that can be used by pods, on a per-network basis.

Restrict volume types

Define the types of volumes that may be used. Examples of volume types are configMap, downwardAPI, emptyDir, persistentVolumeClaim, secret, projected, hostPath, flexVolume.

Restrict host filesystem paths

Define the host paths that are allowed when using hostPath volumes.

Restrict drivers

Define the FlexVolume drivers that can be used.

Require read-only root filesystem

Specify that containers must run with a read-only root filesystem.

Restrict User and group ids

Controls which user ID or group ID the containers are run with or which group IDs get added. For users, specify MustRunAs to define specific user ID ranges, MustRunAsNonRoot to require non-root users, or RunAsAny to permit running as any user. For groups, specify MustRunAs, MayRunAs or RunAsAny.

Restrict escalation to root privileges

Controls the user privileges and prevents files from enabling extra capabilities.

Restrict Linux capabilities

Define the capabilities available to the pod. Set allowed capabilities to specify those capabilities that a container can use, and set Required drop capabilities to specify which privileges must be dropped from containers.

Restrict SELinux security context

Controls the SELinux context of the container. You can specify the level, role, type and user.

Restrict Proc Mount types

Defines the type of /proc mount to use for containers. Select either Default or Unmasked.

Restrict AppArmor profiles

Restrict seccomp profiles

Controls the seccomp profile used by containers or pods.

Restrict sysctl profiles

Controls the sysctl profile used by containers. Specify the sysctls to forbid from use by pods.

Once you have completed your configuration, click Save settings to apply your changes.

Policies are based on the - for more detail on each option check the Kubernetes documentation.

Controls the AppArmor profile used by containers. Refer to the for more details.
