# Require `imagePullPolicy` is set to `Always` for images not using `latest` tags
By default, Kubernetes sets the `imagePullPolicy` for images which specify a tag to be `IfNotPresent`. In some cases, this may not be desired where the image could be rebuilt upstream. This sample policy ensures that all containers have their `imagePullPolicy` set to `Always`.
## Policy YAML
[imagepullpolicy-always.yaml](misc/imagepullpolicy-always.yaml)
```yaml
apiVersion : kyverno.io/v1
kind: ClusterPolicy
metadata:
name: imagepullpolicy-always
spec:
validationFailureAction: audit
background: false
rules:
- name: imagepullpolicy-always
match:
resources:
kinds:
- Pod
validate:
message: "The imagePullPolicy must be set to `Always` for all containers when a tag other than `latest` is used."
pattern:
spec:
containers:
- imagePullPolicy: Always
```
