I try to have entries by searching for a boolean with yq

Question

Good evening!

I am trying to get with yq the entries looking for a boelan value inside a yml.

e.g:

 yq '.applications | to_entries | .[] | select( .persistence == "true")' manifest.yml 

But this does not return anything... this would be the yml where I look for:

applications:
  a:
    enabled: true
    project: ../../../aproj
    version: v1.0.1
    persistence: true
  b:
    enabled: false
    project: ../../bproj
    version: v1.0.1
  c:
    enabled: true
    project: ../../../cproj
    version: v1.0.1
    persistence: true

the output should be the following entries: a,c

This seems to be a duplicate of another question - but for completion:

yq '.applications[] | select(.persistence == true) | key' file.yaml

Explanation:

• .applications[] Expand all the map values in applications
• select(.persistence == true) select the ones with persistence = true
• key get their key

Disclaimer: I wrote yq
