Is there any resource out there that gives an overview of all the possible status conditions a kubernetes job can have?
I'm wondering because I would like to check, when I run a job if it is already running and if so, exit the new job.
I came across until kubectl get jobs myjob -o jsonpath='{.status.conditions[?(@.type=="Complete")].status}' | grep True ; do sleep 1 ; done quite a few times but I want to know if it is running, not if it is already complete. Would prefer not to wait (ha) for kubectl 1.11 wait functionality
回答1:
https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.11/#jobcondition-v1-batch implies the only type values are “Complete” and “Failed”, and that they may have a ”True” or ”False” status.
In addition to the job status conditions array, you may also find it informative to look at the job status active count, and the startTime and completionTime if you’re just interested in whether it’s finished.

kubectl get jobs <myjob> --namespace <mynamespae> -o jsonpath='{.status.conditions[?(@.type=="Succeeded")].status}'

I believe this can help to get all job statuses for a given selector and after the result can be parsed in bash or CI to wait until some specific statuses:
kubectl get job -n myspace --selector=appName=myapplication -o json | jq -r '.items[] | .metadata.name + ":" + (.status.conditions[] | select(.status == "True") .type + ":" + .status)'
myapplication-job-1558097758:Complete:True
myapplication-job-1558101228:Failed:True
Also here I found another example for bash:
Wait for kubernetes job to complete on either failure/success using command line
By @ruazn2:
until [[ $SECONDS -gt $end ]] || [[ $(kubectl get jobs $job_name -o jsonpath='{.status.conditions[?(@.type=="Failed")].status}') == "True" ]] || [[ $(kubectl get jobs $job_name -o jsonpath='{.status.conditions[?(@.type=="Complete")].status}') == "True" ]]; do
