Today I spent about 1 hours in the task Deploy Lamp Stack on Kubernetes Cluster - Task. This task deepen my understanding of ini file handling and volume mounting with subpath. I think there are 2 tricky parts make the task interesting. First, the similarity between --from-literal=variables_order=EGPCS and variables_order = "EGPCS" in php.ini make one try to create a configmap at first. However it is not the case. the actual volumemount will mount each key as a file

I did resize volume of kubernetes in the past, however I encountered an interesting issue when I did the resizing in different way. According to doc, I should only change the requested size in pvc. Today I changed the size of pv first, then pvc. Here was the interesting thing: all things of pv and pvc are fine, but the size of the file system in pod was not changed.
