HOW CAN I UPDATE MY PERSONAL ORKA SERVER?

If there are updates in the main e-Science github repo, you can update your Personal Orka Server by running the python script deploy_orka_server.py with the 'update' argument and the deploy file used for starting the server. As usual it is pretty simple:

$ ssh root@{{orka_server_ip}}
$ su - orka_admin
$ cd projects/e-science/deploy
$ python deploy_orka_server.py update <path_to_user_created_yaml_file>

If you deleted the deploy file you can follow the instructions in How to restart my Personal Orka Server? section to create it again.

Keep in mind that the default github repo that deploy_orka_server.py will look for updates is https://github.com/grnet/e-science.git at the master branch. The github repo and branch/version is set in e-science/deploy/group_vars/webserver.yml file and can be changed.
