kubectl diff

[Vad1mo]

The diff in Kubectl can be altered with KUBECTL_EXTERNAL_DIFF here is the ref

These options do all work:

• KUBECTL_EXTERNAL_DIFF="colordiff -N -u"
• KUBECTL_EXTERNAL_DIFF="dyff between --omit-header --set-exit-code"
• KUBECTL_EXTERNAL_DIFF='diff -qr'

I can't, however, make it work with graphtage using the following config

KUBECTL_EXTERNAL_DIFF="graphtage --from-yaml --to-yaml --debug " kubectl diff -f ./dist/aws/cert-manager.k8s.yaml

Traceback (most recent call last):
  File "/Users/vadim/.local/bin/graphtage", line 8, in <module>
    sys.exit(main())
  File "/Users/vadim/.local/lib/python3.10/site-packages/graphtage/__main__.py", line 323, in main
    from_tree = from_format.build_tree_handling_errors(from_path, options)
  File "/Users/vadim/.local/lib/python3.10/site-packages/graphtage/yaml.py", line 236, in build_tree_handling_errors
    return self.build_tree(path=path, options=options)
  File "/Users/vadim/.local/lib/python3.10/site-packages/graphtage/yaml.py", line 228, in build_tree
    tree = build_tree(path=path, options=options)
  File "/Users/vadim/.local/lib/python3.10/site-packages/graphtage/yaml.py", line 23, in build_tree
    with open(path, 'rb') as stream:
IsADirectoryError: [Errno 21] Is a directory: '/var/folders/v5/27sfclt13g54_qgh9kmkqf6w0000gn/T/LIVE-3245526907'

How could I accomplish that with graphtage?
