如何在 jenkins 中以有效的 json 格式转换 kubectl 命令？

Question

I am trying to parse in Jenkins the output of a kubectl command. My goal is to get how old a container is. I am trying to run:

myPods= sh(script:" kubectl get pods -o json", returnStdout: true)
test = readJSON text: myPods

Even though the output of echo myPods seems to be a valid json, I keep getting:

net.sf.json.JSONException: Invalid JSON String

Answer 1

Check out the myPods variable content, it might be some kubectl error logs.
