Today I tried to install a small POC environment for the Customizer only. 1 master node and 2 workers.
Following the IBM documentation is straight forward. In my POC I relied on the Deploying a non-HA Kubernetes platform path.
I went through the docs and copied all the pieces into a couple of shell scripts. So I’d be able to restart from scratch if something goes wrong.
The only point I had issues was on how to setup the docker image registry. For my POC I did not want to fiddle around with certificates. So I decided to follow this link. If I had updated the daemon.json file on every worker node too, I would have been much more efficient. After this little change, my worker nodes were finally able to pull the images.
Despite the documentaions first impression, the overall installation experience was interesting.
At the moment I only run the customizer on my POC environment. After a clean reboot all 3 Nodes take less then 8GB ram. Lets see how this will raise if I start using the the customizer tomorrow.
