Get the image and SHA image ID of images in pod on Kubernetes deployment

An example without jq usage.

Using jsonpath:

kubectl get pods $YOUR_POD_NAME -o jsonpath="{..imageID}"

Using go-templates

kubectl get pods $YOUR_POD_NAME -o go-template --template="{{ range .status.containerStatuses }}{{ .imageID }}{{end}}"

Reference: https://kubernetes.io/docs/tasks/access-application-cluster/list-all-running-container-images/#list-containers-filtering-by-pod-namespace

Right way to do this:

kubectl get pods --all-namespaces -o jsonpath="{.items[*].status.containerStatuses[*].imageID}" | tr -s '[[:space:]]' '\n' | sort | uniq -c

The simplest one to use is:

For getting images SHA value of all the pods in a single namespace:

• kubectl get pods -n <your-namespace> -o=jsonpath='{range .items[*]}{"\n"}{.metadata.name}{":\t"}{range .spec.containers[*]}{.image}{", "}{end}{end}'

For getting images SHA value of all the pods in all the namespace:

• kubectl get pods --all-namespaces -o=jsonpath='{range .items[*]}{"\n"}{.metadata.name}{":\t"}{range .spec.containers[*]}{.image}{", "}{end}{end}'
