# Sample Policies
|
|
|
|
Sample policies are designed to be applied to your Kubernetes clusters with minimal changes.
|
|
|
|
The policies are mostly validation rules in `audit` mode i.e. your existing workloads will not be impacted, but will be audited for policy complaince.
|
|
|
|
## Best Practice Policies
|
|
|
|
These policies are highly recommended.
|
|
|
|
1. [Disallow root user](DisallowRootUser.md)
|
|
2. [Disallow privileged containers](DisallowPrivilegedContainers.md)
|
|
3. [Disallow new capabilities](DisallowNewCapabilities.md)
|
|
4. [Disallow kernel parameter changes](DisallowSysctls.md)
|
|
5. [Disallow use of bind mounts (`hostPath` volumes)](DisallowBindMounts.md)
|
|
6. [Disallow docker socket bind mount](DisallowDockerSockMount.md)
|
|
7. [Disallow `hostNetwork` and `hostPort`](DisallowHostNetworkPort.md)
|
|
8. [Disallow `hostPID` and `hostIPC`](DisallowHostPIDIPC.md)
|
|
9. [Disallow use of default namespace](DisallowDefaultNamespace.md)
|
|
10. [Disallow latest image tag](DisallowLatestTag.md)
|
|
11. [Disallow Helm Tiller](DisallowHelmTiller.md)
|
|
12. [Require read-only root filesystem](RequireReadOnlyRootFS.md)
|
|
13. [Require pod resource requests and limits](RequirePodRequestsLimits.md)
|
|
14. [Require pod `livenessProbe` and `readinessProbe`](RequirePodProbes.md)
|
|
15. [Add default network policy](AddDefaultNetworkPolicy.md)
|
|
16. [Add namespace quotas](AddNamespaceQuotas.md)
|
|
17. [Add `safe-to-evict` for pods with `emptyDir` and `hostPath` volumes](AddSafeToEvict.md)
|
|
|
|
## Additional Policies
|
|
|
|
These policies provide additional best practices and are worthy of close consideration. These policies may require specific changes for your workloads and environments.
|
|
|
|
17. [Restrict image registries](RestrictImageRegistries.md)
|
|
18. [Restrict `NodePort` services](RestrictNodePort.md)
|
|
19. [Restrict auto-mount of service account credentials](RestrictAutomountSAToken.md)
|
|
20. [Restrict ingress classes](RestrictIngressClasses.md)
|
|
21. [Restrict User Group](CheckUserGroup.md)
|
|
|
|
## Applying the sample policies
|
|
|
|
To apply these policies to your cluster, install Kyverno and import the policies as follows:
|
|
|
|
**Install Kyverno**
|
|
|
|
````sh
|
|
kubectl create -f https://github.com/nirmata/kyverno/raw/master/definitions/install.yaml
|
|
````
|
|
<small>[(installation docs)](../documentation/installation.md)</small>
|
|
|
|
**Apply Kyverno Policies**
|
|
|
|
To start applying policies to your cluster, first clone the repo:
|
|
|
|
````bash
|
|
git clone https://github.com/nirmata/kyverno.git
|
|
cd kyverno
|
|
````
|
|
|
|
Import best_practices from [here](best_pratices):
|
|
|
|
````bash
|
|
kubectl create -f samples/best_practices
|
|
````
|
|
|
|
Import addition policies from [here](more):
|
|
|
|
````bash
|
|
kubectl create -f samples/more/
|
|
````
