label_replace - extract string from label_value

[Nabil L.]

Hi Folks,

I wonder if someone know how to extract a string from a label_value  and using the the label_replace .

For example I have the following metric, which return

kube_pod_container_info which return the following metric:

{container="d2conf", container_id="docker://9e9fdd34fa960000abbf309c279a19fcae828646a7b11169292c7da05e3349c9", image_id="docker-pullable://docker-registry/toto-jx/deploy-ws@sha256:d6c2db22b2b677a7c6017d6f3eeb4055750750349a48b716d6215721ccce1aa8", instance="kube-state-metrics.kube-system.svc.cluster.local:8080", job="kube-state-metrics", namespace="toto", pod="d2conf-1", image="docker-registry/toto/deploy-ws:1.4.2"}    

Using  the label_replace, the label image is replaced by release, but what I need as well is to extract the string after character ":" in the label value (below in yellow)

sum without (image) (label_replace(kube_pod_container_info, "release", "$1", "image", "(.*)"))

{container="d2conf", container_id="docker://9e9fdd34fa960000abbf309c279a19fcae828646a7b11169292c7da05e3349c9", image_id="docker-pullable://docker-registry/toto-jx/deploy-ws@sha256:d6c2db22b2b677a7c6017d6f3eeb4055750750349a48b716d6215721ccce1aa8", instance="kube-state-metrics.kube-system.svc.cluster.local:8080", job="kube-state-metrics", namespace="toto", pod="d2conf-1", release="docker-registry/toto/deploy-ws:1.4.2"}  

any idea?

Thanks in advance

Neb.

maybe:

sum without (image) (label_replace(kube_pod_container_info, "release", "$1", "image", ".*:([^:]*)"))
