Questions send to for SURF Research cloud support

I am writing my own plugin where I need to set the public URL in an application config file using an Ansible task. In the logs of a workspace I see a service_url key with value https://d08d27c8-d63d-492f-9479-70aa98b90f81.workspaces.live.surfresearchcloud.nl. When I try to use that var in my Ansible task, then it is not set. Can this service_url var be supplied to where my plugin is being run?

I am writing my own plugin where I have 2 storage items (mainly because system disk is too small):

  1. A read only disk with data
  2. A scratch disk with intermediate results for all CO members I looked at the resource_meta dict, but it only contains internal uuids, not the name I gave my storage items. In a Ansible task how do I distinquish between them as they need to be mounted differently?

I am starting workspace with my own application+plugin. When things fail the logs show a long line with the output of my plugin. However when my plugin completes succesfully I don't see any mention of my plugin tasks in the log. I am printing some messages in the plugin about where parts of the application are running, but I can not see them in the logs. Can the output of external plugins always be logged just like the internal plugins (RSC-OS, RSC-CO, RSC-Nginx)?

For my plugin I need to install conda. There are some ready made roles on Ansible Galaxy like https://galaxy.ansible.com/evandam/conda that I would like to use. To use locally I would create requirements.yml for example https://github.com/eWaterCycle/infra/blob/5efee1c5915aa4a8157c50053b093557944ccd5c/requirements.yml . And then run ansible-galaxy install -r requirements.yml to install those roles. Can the RSC-External plugin be extended to install the roles from Ansible Galaxy?

  3. How to mark certain user as JupyterHub admin -> use sram api to sync posix group
  4. How to put home dirs on attached storage
  5. What is symlink to /scratch doing in homedir? How to tie storage item to it?
    • each user has symlink ~/data -> /data, which has disks as subdirs
    • each user has symlink ~/scratch -> /scratch , which points to root disk
  6. Fetch workspace.json from https//gw.live.surfresearchcloud.nl/workspace/workspaces gives "Access to this API has been disallowed" error
