==== 2. Creating a checkpoint of the running container ====
==== 2. Create <code>client-admin.crt</code> and <code>client-admin.key</code> files ====
These certificate and key files will be used to authorize the use of the checkpoint API:
<pre>
<pre>
kubectl config view --raw --minify -o jsonpath='{.users[0].user.client-certificate-data}' \
kubectl config view --raw --minify -o jsonpath='{.users[0].user.client-certificate-data}' \
chmod 600 client-admin.key
chmod 600 client-admin.key
</pre>
</pre>
==== 3. Creating a checkpoint of the running container ====
<pre>
curl --insecure \
--cert client-admin.crt \
--key client-admin.key \
-X POST "https://localhost:10250/checkpoint/default/counters/counter"
</pre>
The <code>--insecure</code> command-line option is necessary for <code>curl</code> to accept the kubelet's self-signed certificate.
