Reference documentation

The full structure of the Command is documented here.
This operation supports bindings.
This operation supports outputs.

Usage examples¶

Below is an example of using command in a Test resource.

Example

apiVersion: chainsaw.kyverno.io/v1alpha1
kind: Test
metadata:
  name: example
spec:
  steps:
  - try:
    # ...
    - command:
        entrypoint: echo
        args:
        - hello chainsaw
    # ...

When defining shell command args in YAML format, it's crucial to consider potential differences in behavior, as Chainsaw may interpret them differently compared to regular shell or bash environments, due to quote removal.

Operation check¶

Below is an example of using an operation check.

With check

# ...
- command:
    entrypoint: echo
    args:
    - hello chainsaw
    check:
      # an error is expected, this will:
      # - succeed if the operation failed
      # - fail if the operation succeeded
      ($error != null): true
# ...
