I'm working with Kubernetes atm, and was trying / failing to retrieve a specific Secret
This was what I was running: -
kubectl get secret bootstrap-token-abcdef --namespace kube-system --output JSON | jq .data.token-secret
but jq was borking with: -
jq: error: secret/0 is not defined at <top-level>, line 1:
.data.token-secret
jq: 1 compile error
whereas other similar keys were being retrieved just fine: -
kubectl get secret bootstrap-token-abcdef --namespace kube-system --output JSON | jq .data.description
This occurred whether I was using Zsh or Bash as my Mac's shell
Note the difference ?
Yes, the working key does NOT have a hyphen ( - ) whereas the failing key surely does ...
This helped: -
namely: -
You can use ."" syntax, like jq '."app-code"'
Hmm, I thought, and tried that: -
kubectl get secret bootstrap-token-abcdef --namespace kube-system --output JSON | jq '.data."token-secret"'
Yay!
I also wanted the output in raw format, so added in a -r switch: -
kubectl get secret bootstrap-token-abcdef --namespace kube-system --output JSON | jq -r '.data."token-secret"'
Good to know
