Hi Everyone,
I am recovering from VeeamON. The travel and the fact that I had to perform a big migration of 160 VOIP PBX servers from one end of the country to the other at 10PM for 4 hours both on Tuesday and Wednesday nights made it a wild event. Thank goodness I don’t drink beer anymore!
Phone servers are very finicky and if there are any issues they cut off calls which results in angry consumers filled to the brim with vicious complaints, so you have to get everything done right with next to no margin for error.
For the migration I leveraged Veeam so just because you are learning Kubernetes don’t forget your Veeam skills. On a side note about certifications and their value. If it had not been for VMCE I would never have remembered or been aware of the fact that DirectNFS will only be used on the initial replication job and going forward it will use Network mode because of the presence of snapshots (which Veeam uses for retention)! So don’t believe the Nay Sayers Certifications are worth it!!
Speaking of certifications, it has been 3 years since I passed the CKA so that means I get to do it again. IT is gift that keeps on giving. Unlike University or Colleges, you don’t just get your degree and wander off to some field to slowly disappear into oblivion. In IT you keep coming back for more. Veeam too now are letting us become students again every 2 years since that will be the duration of VMCE and VMCA. This has caused much joy in the Vanguard and Legend community since the latter are always ready for extra work :) (well 3 years would be nice to be honest but...)
A lot has changed since I did the CKA. It has been reduced to 2 hours from 3 which is not necessarily a good thing. A big chunk of the security topics have been moved to the CKS exam and of course Kubernetes itself has evolved.
So as I start my journey down the renew my certs road I was thinking about adding a new series “Pass your CKA with Rancher Desktop”. The idea would be to produce a weekly post on a given CKA study area with examples and instructions made in Rancher Desktop (RD). Remember apart from the default K3S installation in RD, you can also disable the K3S and turn on Moby dockerd which in turn allows you to create multi node clusters with K3D.
I will continue to produce my weekly K10 Documentation series but thought this CKA study initiative might help others and myself get past this very difficult exam.
