|---|---|---|---|
| k8s | 1 master, 2 worker | flannel | K8s cluster |
| hk8s | 1 master, 2 worker | calico | K8s cluster |
| bk8s | 1 master, 1 worker | flannel | K8s cluster |
| wk8s | 1 master, 2 worker | flannel | K8s cluster |
| ek8s | 1 master, 2 worker | flannel | K8s cluster |

- OS: Linux
- Each task on this exam must be completed on a designated cluster/configuration context.
- To minimize switching, the tasks are grouped so that all questions on a given cluster appear consecutively
- At the start of each task you'll be provided with the command to ensure you are on the correct cluster to complete the task
- Nodes making up each cluster can be reached via ssh:
ssh nodename - You can assume elevated privileges on any node by issuing the following command:
sudo -i - You must return to the base node (hostname node-1) after completing each task
- Nested−ssh is not supported
- You can use kubectl and the appropriate context to work on any cluster from the base node When connected to a cluster member via ssh, you will only be able to work on that particular cluster via kubectl
- Further instructions for connecting to cluster nodes will be provided in the appropriate tasks
- Where no explicit namespace is specified, the default namespace should be acted upon
- If you need to destroy/recreate a resource to perform a certain task, it is your responsibility to back up the resource definition appropriately prior to destroying the resource
