1 year ago Looks like our "getting started" part of the readme is a bit incomplete - we miss a few dependencies:
- python 3(>=.11?)
- node and npm (>=16?)
The Python dependency has been added to the README and the Node.js / npm dependency is not required anymore in https://github.com/DSD-DBS/capella-collab-manager/pull/763/commits/3d898ea9aa85f0c2b64fd48d745031fa44044421
it also could be an improvement in onboarding experience if we point a new starter to the published capella-dockerimages instead of build-from-scratch (saving build time).
Implemented in https://github.com/DSD-DBS/capella-collab-manager/pull/763/commits/7624150737a0f6781b615f139e574af3ce5c8574. When the development mode is disabled, the Capella tool is initialized with the public Github images.
another question - do we still need EASE image?
Yes, they are still needed for the read-only images. A dependency graph is available here: https://dsd-dbs.github.io/capella-dockerimages/#build-images-manually-with-docker
next observation - after successfull launch the thing serves on 0.0.0.0:8080, however requesting that from anything that is not localhost results in 404 (design or intention?)
To listen on a different host, please change the .general.host value to the preferred value, e.g., 127.0.0.1. Note that the OAuth mock still redirects to localhost:8080, the value .backend.authentication.oauth.redirectURI has to be changed in the values.yaml too.
In theory, you can also listen on all hosts by removing the host key in line 20 of helm/templates/routing/nginx.ingress.yaml. However, we don't support it from the application side, so the Guacamole and Jupyter redirects will still use the host defined in the values.yaml. If this is a wanted feature, we can also add support for wildcard hosts.
running the thing on a headless server leads to the below error (there is no browser to open):
/bin/bash: line 7: xdg-open: command not found make: *** [Makefile:93: open] Error 127
Out of the box, session start fails with "an error occured, please try again" - but trying again leads to the same result as nothing changed ;-)
The backend error log is full of exciting messages:
- Could not create an admin token. Please make sure that your Guacamole database is initialized properly. (File "/tmp/backend/capellacollab/sessions/guacamole.py", line 44, in get_admin_token)
The first error message is because of the not initialised database of Guacamole. Most likely, the first run of your make deploy ran into a timeout and never reached the Guacamole provision part.
- Exception during fetching of last seen. (requests.exceptions.ReadTimeout: HTTPConnectionPool(host='dev-prometheus-server', port=9118): Read timed out. (read timeout=2), File "/tmp/backend/capellacollab/sessions/sessions.py", line 41, in get_last_seen)
- Could not handle idle sessions ( File "/tmp/backend/capellacollab/sessions/idletimeout.py", line 50, in loop)
My guess is that Prrometheus is not running properly. Can you please share the output of the following command?
kubectl -n collab-manager logs deployment/dev-prometheus-serverrunning

This is how the log should look like :)
