apply
The apply command is used to perform a dry run on one or more policies with a given set of input resources. This can be useful to determine a policy’s effectiveness prior to committing to a cluster. In the case of mutate policies, the apply command can show the mutated resource as an output. The input resources can either be resource manifests (one or multiple) or can be taken from a running Kubernetes cluster. The apply command supports files from URLs both as policies and resources.
Apply to a resource:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml
Apply a policy to all matching resources in a cluster based on the current kubectl context:
1kyverno apply /path/to/policy.yaml --cluster
The resources can also be passed from stdin:
1kustomize build nginx/overlays/envs/prod/ | kyverno apply /path/to/policy.yaml --resource -
Apply all cluster policies in the current cluster to all matching resources in a cluster based on the current kubectl context:
1kubectl get clusterpolicies -o yaml | kyverno apply - --cluster
Apply multiple policies to multiple resources:
1kyverno apply /path/to/policy1.yaml /path/to/folderFullOfPolicies --resource /path/to/resource1.yaml --resource /path/to/resource2.yaml --cluster
Apply a policy to a resource with a policy exception:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml --exception /path/to/exception.yaml
Apply multiple policies to multiple resources with exceptions:
1kyverno apply /path/to/policy1.yaml /path/to/folderFullOfPolicies --resource /path/to/resource1.yaml --resource /path/to/resource2.yaml --exception /path/to/exception1.yaml --exception /path/to/exception2.yaml
Apply multiple policies to multiple resources where exceptions are evaluated from the provided resources:
1kyverno apply /path/to/policy1.yaml /path/to/folderFullOfPolicies --resource /path/to/resource1.yaml --resource /path/to/resource2.yaml --exceptions-with-resources
Apply a mutation policy to a specific resource:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml

Save the mutated resource to a file:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml -o newresource.yaml
Save the mutated resource to a directory:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml -o foo/
Run a policy with a mutate existing rule on a group of target resources:
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml --target-resource /path/to/target1.yaml --target-resource /path/to/target2.yaml

Apply a policy containing variables using the --set or -s flag to pass in the values. Variables that begin with {{request.object}} normally do not need to be specified as these will be read from the resource.
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml --set <variable1>=<value1>,<variable2>=<value2>
Use -f or --values-file for applying multiple policies to multiple resources while passing a file containing variables and their values. Variables specified can be of various types include AdmissionReview fields, ConfigMap context data, API call context data, and Global Context Entries.
Use -u or --userinfo for applying policies while passing an optional user_info.yaml file which contains necessary admission request data made during the request.
Note
When passing ConfigMap array data into the values file, the data must be formatted as JSON outlined here.1kyverno apply /path/to/policy1.yaml /path/to/policy2.yaml --resource /path/to/resource1.yaml --resource /path/to/resource2.yaml -f /path/to/value.yaml --userinfo /path/to/user_info.yaml

You can also inject global context entries using variables. Here’s an example of a Values file that injects a global context entry:
1apiVersion: cli.kyverno.io/v1alpha1
2kind: Value
3metadata:
4 name: values
5globalValues:
6 request.operation: CREATE
7policies:
8 - name: gctx
9 rules:
10 - name: main-deployment-exists
11 values:
12 deploymentCount: 1
In this example, request.operation is set as a global value, and deploymentCount is set for a specific rule in the gctx policy.
Policies that have their failureAction set to Audit can be set to produce a warning instead of a failure using the --audit-warn flag. This will also cause a non-zero exit code if no enforcing policies failed.
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml --audit-warn
Additionally, you can use the --warn-exit-code flag with the apply command to control the exit code when warnings are reported. This is useful in CI/CD systems when used with the --audit-warn flag to treat Audit policies as warnings. When no failures or errors are found, but warnings are encountered, the CLI will exit with the defined exit code.
1kyverno apply disallow-latest-tag.yaml --resource=echo-test.yaml --audit-warn --warn-exit-code 3
2echo $?
33
You can also use --warn-exit-code in combination with --warn-no-pass flag to make the CLI exit with the warning code if no objects were found that satisfy a policy. This may be useful during the initial development of a policy or if you want to make sure that an object exists in the Kubernetes manifest.
1kyverno apply disallow-latest-tag.yaml --resource=empty.yaml --warn-exit-code 3 --warn-no-pass
2echo $?
33
Policy Report
Policy reports provide information about policy execution and violations. Use --policy-report with the apply command to generate a policy report for validate policies. mutate and generate policies do not trigger policy reports.
Policy reports can also be generated for a live cluster. While generating a policy report for a live cluster the -r flag, which declares a resource, is assumed to be globally unique. And it doesn’t support naming the resource type (ex., Pod/foo when the cluster contains resources of different types with the same name). To generate a policy report for a live cluster use --cluster with --policy-report.
1kyverno apply policy.yaml --cluster --policy-report
Above example applies a policy.yaml to all resources in the cluster.
Below are the combination of inputs that can be used for generating the policy report from the Kyverno CLI.
| Policy | Resource | Cluster | Namespace | Interpretation |
|---|---|---|---|---|
| policy.yaml | -r resource.yaml | false | Apply policy from policy.yaml to the resources specified in resource.yaml | |
| policy.yaml | -r resourceName | true | Apply policy from policy.yaml to the resource with a given name in the cluster | |
| policy.yaml | true | Apply policy from policy.yaml to all the resources in the cluster | ||
| policy.yaml | -r resourceName | true | -n=namespaceName | Apply policy from policy.yaml to the resource with a given name in a specific Namespace |
| policy.yaml | true | -n=namespaceName | Apply policy from policy.yaml to all the resources in a specific Namespace |
Example:
Consider the following policy and resources:

Case 1: Apply a policy manifest to multiple resource manifests
1kyverno apply policy.yaml -r resource1.yaml -r resource2.yaml --policy-report
Case 2: Apply a policy manifest to multiple resources in the cluster
Create the resources by first applying manifests resource1.yaml and resource2.yaml.
1kyverno apply policy.yaml -r nginx1 -r nginx2 --cluster --policy-report
Case 3: Apply a policy manifest to all resources in the cluster
1kyverno apply policy.yaml --cluster --policy-report
Given the contents of policy.yaml shown earlier, this will produce a report validating against all Pods in the cluster.
Case 4: Apply a policy manifest to multiple resources by name within a specific Namespace
1kyverno apply policy.yaml -r nginx1 -r nginx2 --cluster --policy-report -n default
Case 5: Apply a policy manifest to all resources within the default Namespace
1kyverno apply policy.yaml --cluster --policy-report -n default
Given the contents of policy.yaml shown earlier, this will produce a report validating all Pods within the default Namespace.
On applying policy.yaml to the mentioned resources, the following report will be generated:

Applying Policy Exceptions
Policy Exceptions can be applied alongside policies by using the -e or --exceptions flag to pass the Policy Exception manifest.
1kyverno apply /path/to/policy.yaml --resource /path/to/resource.yaml --exception /path/to/exception.yaml
Example:

The above policy verifies that the number of deployment replicas is not greater than 5 and is limited to a namespace labeled environment: staging.
Create a Namespace with the label environment: staging:
1kubectl create ns staging
2kubectl label ns staging environment=staging
Create two Deployments, one of them in the staging namespace, which violates the policy.
1kubectl create deployment nginx-1 --image=nginx --replicas=6 -n staging
2kubectl create deployment nginx-2 --image=nginx --replicas=6
Get all Deployments from the cluster:
1kubectl get deployments -A

Apply the ValidatingAdmissionPolicy with its binding to all resources in the cluster:
1kyverno apply /path/to/check-deployment-replicas.yaml --cluster --policy-report
The following output will be generated:

As expected, the policy is only applied to nginx-1 as it matches both the policy definition and its binding.
