Fixes issue #908

Proposed Changes

Overhaul of the validation support to greatly improve its use.
New proposed configuration:

    validate:
    - type: kubernetes
      fail_on_error: false
      verbose: true
      exclude:
        kinds:
        - HorizontalPodAutoscaler
        paths:
        - manifests/*-ingress.yml
      output_paths:
        - manifests/*.yml
      version: 1.26.0

Example output

kapitan compile -t tesoro prod-sockshop argocd
Rendered inventory (0.18s)
Compiled tesoro (0.07s)
Compiled prod-sockshop (0.28s)
Compiled argocd (0.81s)
Validated tesoro FAIL
INVALID [MutatingWebhookConfiguration]: manifest ./compiled/tesoro/manifests/tesoro-bundle.yml
---> ERROR ['webhooks', 0]: 'sideEffects' is a required property
---> ERROR ['webhooks', 0]: 'admissionReviewVersions' is a required property

Validated prod-sockshop OK (with 3 exclusion/s)
Validated argocd OK (with 5 exclusion/s)
Validated targets (7.70s)

Features

  • supports globbed paths on output_paths
  • uses https://github.com/kapicorp/kubernetes-json-schema instead of deprecated repo
  • improved output
  • only fails at the end of the validation to surface all errors at once
  • autodetects resource kind
  • silently ignore resources not available in the schema
  • does not output anything if there are no files to validate (for non kubernetes targets)
  • detects if schema exists by querying well known url for "all" kind
  • supports files which contain multiple yaml documents
  • support "fails_on_error" flag to make explicit whether to fail validation or not
  • exclusion based on
    • kind
    • file
    • annotation

@ademariag we should make sure that some sort of globbing works as users may or may not have a nested directory structure.

  1. validate[*].exclude and validate[*].exclude.paths are seamingly required even If I dont want to exclude stuff
  2. validate[*].kind should also be validate[*].kinds[*] as user may or may not want to specify every kind
  3. A user may or may not want to specify a kind(s)
  4. If possible, can we make sure that 1.18 instead of 1.18.0 always uses the latest major version? In this case it would for example be 1.18.20
  5. fail_on_error: false should be the default - A user might want to see every error to fix them instead of re-run kapitan after every fix
  6. Validated <target_name> FAIL - should also print the kubernetes version on which it has failed
  7. output_paths might be a little confusing, as a user may expect to input files into the validator (personal opinion)
  8. print message on success, similar to kapitan compile

This....

My structure for example has compiled/<target_name>/k8s/loki/loki-distributed.yml

    validate: 
    - type: kubernetes 
      output_paths: 
        - "k8s/**/*.yml"
        - "k8s/**/*.yaml"
      exclude:
        paths: []
      version: 1.18.0

leads to:

$ kapitan validate

The above exception was the direct cause of the following exception:
