naislinter

A simple Python script to validate that your NAIS yaml file adheres to the NAIS specifications.

Local installation

$ pip install naislinter

Local usage

$ naislinter nais.yaml

Will print any path in the config tree that falls outside of the spec and return a non-zero code if any were encountered.

Returns 0 if the file is valid according to the NAIS specifications.

Limitations

This does not validate value types, this is not in scope as nais/deploy verifies types and rejects a deployment if the NAIS yaml file is malformed in this fashion.

Additionally, this tool requires a fully formed NAIS yaml file, after any template injections. A file containing {{ image }} will therefore fail, unless the variable has been injected.

Finally, in its current state, the tool is unable to verify objects within lists. For instance:

spec:
    env:
        - name: KEY
          value: value
        - name: ANOTHER_KEY
          value: another_value
          key_outside_of_spec: hello!

key_outside_of_spec will not be caught as an error since it's in an object within a list.
