I want given a Job name find name of created Pod by Job controller using the OpenShift or Kubernetes REST API.
Using the CLI, this is possible by doing:
$ oc describe job testapi | grep -A 4 Events
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal SuccessfulCreate 6m job-controller Created pod: testapi-gff8c
Can we do same operation using the REST API?
I would like to get Pod names to get logs of all pods generated by a Job.
The describe command is aggregating multiple results to provide its output so you will need to do a bit of extra work.
Call the events endpoint and parse the results using a tool like jq or can be pulled out in part by grep.
Heres an example assuming the job name is testapi and the namespace is myproject:
curl -H "Authorization: Bearer $(oc whoami -t)" -k https://127.0.0.1:8443/api/v1/namespaces/myproject/events?fieldSelector=involvedObject.name%3Dtestapi%2CinvolvedObject.namespace%3Dmyproject%2CinvolvedObject.kind%3DJob | grep Created
