I have pulled images from Docker before - some time ago - but now it seems things have changed.
Take for example https://hub.docker.com/r/datagrip. Documentation states installation as follows
docker pull sath89/oracle-xe-11g
This no longer works with current Docker hub. I can try latest
[myuser:~] $ docker pull sath89/oracle-xe-11g
Using default tag: latest
Error response from daemon: pull access denied for sath89/oracle-xe-11g, repository does not exist or may require 'docker login'
Or tag 11.2
[myuser:~] 1 $ docker pull sath89/oracle-xe-11g:11.2
Error response from daemon: pull access denied for sath89/oracle-xe-11g, repository does not exist or may require 'docker login'
Of course I can try login - login succeeds but pulling images is still not working.
[myuser:~] 1 $ docker login

What is the secret nowadays for pulling images from Docker hub? It used to be so easy. Too easy clearly.
