<p>In the Kubernetes documentation <a href="https://kubernetes.io/docs/tasks/access-application-cluster/list-all-running-container-images/#list-all-container-images-in-all-namespaces" rel="noreferrer">List All Container Images Running in a Cluster</a> we can list all containers by:</p>

<pre><code>kubectl get pods --all-namespaces -o jsonpath="{..image}" |\
tr -s '[[:space:]]' '\n' |\
sort |\
uniq -c
</code></pre>

<p>Here is an example of output:</p>

<p>Unfortunately the size of the docker image is missing. Is there a way to get the container image size? Pretty much like <code>docker image ls</code>. Copy of the output from this <a href="http://www.askdevops.org/63/docker-list-all-images-local-docker-image-ls-example" rel="noreferrer">example</a> for convenience:</p>

<pre><code>$ docker image ls
REPOSITORY                  TAG                 IMAGE ID            CREATED             SIZE

<p>If you have the correct permissions, get the nodes not the pods.</p>
<pre><code>kubectl get nodes -o json | jq '.items[].status.images[] | .names[1], .sizeBytes'
</code></pre>
