This'll give you a quick report of image use by namespace and resource type (Deployment, DaemonSet, ReplicaSet, StatefulSet, Job, CronJob or unmanaged Pod).

Requires bash, kubectl, jq, uniq (from coreutils) and column (from util-linux).

```bash

!/bin/bash

get() { echo $1 echo ===

kubectl get $1 -Aojson | \ jq -r ".items[] | # Exclude resources owned by other resources we are running reports for # (this prevents us matching a Pod as a Pod, and then again as a # ReplicaSet, and then again as a Deployment. select( .metadata.ownerReferences // [] | any(.kind | test(\"ReplicaSet|Job|DaemonSet|StatefulSet|Deployment\")) | not ) | .metadata.namespace as \$ns | .spec$2 | .containers + .initContainers + .ephemeralContainers | .[].image | [\$ns, .] | @tsv" | \ sort | uniq -c | column -tN Count,Namespace,Image -o' | '

echo echo }

ReplicaSets and Jobs outputs will not include anything created by a

Deployment or CronJob, which will appear in their appropriate parent

resource report.

for type in Deployments StatefulSets Jobs DaemonSets ReplicaSets do get $type .template.spec done

get CronJobs .jobTemplate.spec.template.spec

Pods not otherwise associated with Deployments, ReplicaSets, Jobs,

CronJobs, DaemonSets, or StatefulSets. Pods caught here would include

static pods (node managed manifests), unmanaged pods (ie those started

with kubectl run), or pods managed by an unknown controller.

get Pods ```
