My journey to Certified Kubernetes Administrator (CKA)

The Journey Is More Important Than the Destination.

CKA: Certified Kubernetes Administrator
Certified Kubernetes Administrator (CKA)
  • CKA is the most touching exam I have passed.
  • The Journey Is More Important Than the Destination.
  • Fastest practice skills are crutial.
  • Have fun.

My tips

Use kubectl Cheat Sheet

Kubectl autocomplete – BASH

source <(kubectl completion bash) # setup autocomplete in bash into the current shell, bash-completion package should be installed first.
echo "source <(kubectl completion bash)" >> ~/.bashrc # add permanently

You can also use a shorthand alias for kubectl that also works with completion:

alias k=kubectl
complete -F __start_kubectl k

Kubectl apply 

kubectl apply -f ./my-manifest.yaml            # create resource(s)

Interacting with running Pods

# Run pod nginx and write its spec into a file called pod.yaml
kubectl run nginx --image=nginx --dry-run=client -o yaml > pod.yaml

#Better usage with $do
export do="–dry-run=client -o yaml"
kubectl run nginx --image=nginx $do > pod.yaml

Great Vim

vi ~/.vimrc
set ts=2 sw=2 expandtab ruler

Use tmux

A Ctrl+B Cheat Sheet

Session Commands
  • S: List sessions.
Window Commands
  • C: Create a new window.
  • N: Move to the next window.
  • P: Move to the previous window.
Pane Commands
  • %: Create a horizontal split.
  • “: Create a vertical split.
  • X: Close the current pane.

Updated Plan for CPU Support Discontinuation In Future Major vSphere Releases after 7.0 (82794)

During instalation vSphere 7.0 Update 2 and later we can see new message for Haswell and Broadwell CPUs.

This is the warning message shown by the ESX installer:

CPU_SUPPORT_WARNING: The CPUs in this host may not be supported in future ESXi releases. Please plan accordingly.
Summary for warnings
  • vSphere 7.0
    • onwards for Intel Sandy Bridge, Intel Ivy Bridge-DT CPUs and AMD Bulldozer CPUs.
  • Sphere 7.0 Update 2 and later
    • onwards for Intel Haswell,Broadwell, Avoton CPUs and AMD Piledriver CPUs

I wish we could solve this in the future major release with – How to fix? The CPU in this host is not supported by ESXi 7.0.0. -> allowLegacyCPU=True

How to fix vCenter password expiration “Exception in invoking authentication handler User password expired”

The Appliance was deployed more than 90 days ago with default settings. Logging in to the VAMI page of a vCenter (https://:5480) fails with the message “Exception in invoking authentication handler User password expired”

Login to the VCSA Appliance Shell (SSH or VM Console) is working.

Check password expiration
root@localhost [ ~ ]# chage -l root
You are required to change your password immediately (password expired)
chage: PAM: Authentication token is no longer valid; new one required
Change password
root@localhost [ ~ ]# passwd root
New password:
Retype new password:
passwd: password updated successfully
Change expiration – use it only for LABs …
root@localhost [ ~ ]# chage -M -1 root

Verify password expiration
