Hello, @lalitjangra
We don’t require to login into node01. In PV hostPath, you can specify a “type” field.
In the “type” field, there is an option “DirectoryOrCreate”. If the directory doesn’t exist, it will create an empty directory and If it already exists then it’ll be ignored.
Reference:-
PV’ hostPath
