Filter kubectl get based on annotation
Jun 8
I would like to filter my kubectl get deploy command based on the value of an annotation.
Something similar to kubectl get deploy --annotation stork.libopenstorage.org/skipresource!="true"
Currently no clue how to do this and we don't want to add an extra label. Output of both commands above should be something like below:
kubectl get deploy
NAME READY UP-TO-DATE AVAILABLE AGE
elastalert 1/1 1 1 33d
es-hq 1/1 1 1 33d
etcdsnapshots 1/1 1 1 33d
fluentd-aggregator 2/2 2 2 33d
kibana 1/1 1 1 33d
kubectl get deploy --annotation stork.libopenstorage.org/skipresource!="true"
NAME READY UP-TO-DATE AVAILABLE AGE
etcdsnapshots 1/1 1 1 33d
fluentd-aggregator 2/2 2 2 33d
kibana 1/1 1 1 33d
kubectl get deploy --annotation stork.libopenstorage.org/skipresource="true"
NAME READY UP-TO-DATE AVAILABLE AGE
elastalert 1/1 1 1 33d
es-hq 1/1 1 1 33d

I have a deployment with the annotation prometheus.io/scrape="true"
I can get the deployments having that annotation by
kubectl get deploy -o=jsonpath='{.items[?(@.spec.template.metadata.annotations.prometheus\.io/scrape=="true")].metadata.name}'
The above uses the Jsonpath concept and the docs can be found at here
In your case the command might be like
kubectl get deploy -o=jsonpath='{.items[?(@.spec.template.metadata.annotations.stork\.libopenstorage\.org/skipresource=="true")].metadata.name}'
This concept can be applied to other kubernetes resources as well.One other command that might help in understanding the earlier commands is
kubectl get deployment -o=json
