在给定容器ID的情况下如何查找吊舱名称

Question

Is there a way to find the pod name for a given Docker container ID?

I can do it the other way round "kubectl describe pods" but then I have to run it on all the pods.

Yes, you can get the pod name given a container ID using the following kubectl request:

kubectl get pod -o jsonpath='{range .items[?(@.status.containerStatuses[].containerID=="docker://<container_id>")]}{.metadata.name}{end}' -n <namespace>

where <container_id> is the long docker container ID and <namespace> is namespace which we can skip if our pod is in default namespace.

For example:

kubectl get pod -o jsonpath='{range .items[?(@.status.containerStatuses[].containerID=="docker://686bc30be6e870023dcf611f7a7808516e041c892a236e565ba2bd3e0569ff7a")]}{.metadata.name}{end}'
