Etcd Server private key location

 

The cluster admin asked you to find out the following information about etcd running on cluster2-master1:

  • Server private key location
  • Server certificate expiration date
  • Is client certificate authentication enabled

Write these information into /opt/course/p1/etcd-info.txt

Finally you're asked to save an etcd snapshot at /etc/etcd-snapshot.db on cluster2-master1 and display its status.

 

Answer:
Find out etcd information

Let's check the nodes:

First we check how etcd is setup in this cluster:

We see its running as a Pod, more specific a static Pod. So we check for the default kubelet directory for static manifests:

So we look at the yaml and the parameters with which etcd is started:

We see that client authentication is enabled and also the requested path to the server private key, now let's find out the expiration of the server certificate:

There we have it. Let's write the information into the requested file:

 

Create etcd snapshot

First we try:

We get the endpoint also from the yaml. But we need to specify more parameters, all of which we can find the yaml declaration above:

This worked. Now we can output the status of the backup file:

The status shows:

  • Hash: 4d4e953
  • Revision: 7213
  • Total Keys: 1291
  • Total Size: 2.7 MB

Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
