First use: enabling access to your HPCF or ECS account from JupyterHub

Before you can start using this service, you need to enable the access from JupyterHub into your account on the target platform.

A unique SSH key pair is created for this purpose, and you will need to append the generated public SSH key into your ~/.ssh/authorized_keys in your ECMWF HOME space.

You will need to access  Atos HPCF,  ECS or VDI services via other means. From a terminal in one of those systems, you can then:

$ grep -q $USER@jupyter ~/.ssh/authorized_keys || echo "ssh-ed25519 AAAA...." >> ~/.ssh/authorized_keys

Note you should replace "ssh-ed25519 AAAA...." by the actual value of your SSH key that appears in the JupyterHub portal.
