Problem

How to list all root keys in YAML file using yq v4 CLI?

Solution

yq4 is my terminal alias for yq above

Let's print all the root keys if they have enabled sub-key e.g.

foo:
  enabled: true

Command:

$ yq4 e '.[] | select(has("enabled")) | path | .[]' <filename>

Example:

See full values.yaml file here

$ yq4 e '.[] | select(has("enabled")) | path | .[]' values.yaml
