Apply

The apply operation lets you define resources that should be applied to the Kubernetes cluster during the test step.

These can be configurations, deployments, services, or any other Kubernetes resource.

Reference documentation

The full structure of the Apply is documented here.

          data:
            foo: bar
    # ...

metadata:
  name: example
spec:
  try:
  # ...
  - apply:
      file: my-configmap.yaml

kind: TestStep
metadata:
  name: example
spec:
  try:
  # ...
  - apply:
      file: https://raw.githubusercontent.com/kyverno/chainsaw/main/testdata/step/configmap.yaml

kind: TestStep
metadata:
  name: example
spec:
  try:
  # ...
  - apply:
      resource:
        apiVersion: v1
        kind: ConfigMap
        metadata:
          name: chainsaw-quick-start
        data:

  # ...

Operation check

Below is an example of using an operation check.

With check

# ...
- apply:
    file: my-configmap.yaml
    expect:
    - match:
        # this check applies only if the match
        # statement below evaluates to `true`
        apiVersion: v1
        kind: ConfigMap
      check:
        # an error is expected, this will:
        # - succeed if the operation failed
        # - fail if the operation succeeded
        ($error != null): true
# ...

With check

# ...
- apply:
    resource:
      apiVersion: v1
      kind: ConfigMap
      metadata:
        name: chainsaw-quick-start
      data:
        foo: bar
    expect:
    - match:
        # this check applies only if the match
        # statement below evaluates to `true`
        apiVersion: v1
        kind: ConfigMap
      check:
        # an error is expected, this will:
        # - succeed if the operation failed
        # - fail if the operation succeeded
        ($error != null): true
# ...
