quickstart: login yields internal server error

@ltalirz thank you for trying out the Renga platform. First, I would like to find out if it is a problem with Renga platform (renga) or the CLI (renga-python).

Start by removing old configuration (find the path by running):

$ renga --config-path
/Users/<NAME>/Library/Application Support/Renga/config.yml

Please upload logs to Gist or Pastebin from docker-compose logs and list of installed packages by running pip freeze and send us a link.

Then you can check if we have already fixed the platform by running make wipe && docker-compose pull && make start and also install the latest CLI by running pip install -U -e git+https://github.com/SwissDataScienceCenter/renga-python.git#egg=renga.

@jirikuncar thanks for having a look at this
I followed all your instructions, but unfortunately to no avail (the errors both in the web frontend and the cli remain the same).

Here the two logs you asked for:
https://gist.github.com/ltalirz/0aaa28a2f8a2d18475fbf3eba0810121
https://gist.github.com/ltalirz/bcffe7b02f0b1d32eaef239f5ccbcd36

I noticed one thing (perhaps unrelated):
I used to have to run all my docker commands via sudo or they would simply hang (I now realized that I had some environment variables configured that would connect to a different, unavailable docker host). I.e. I did sudo make start.

After removing the environment variables, I did make wipe && docker-compose pull && make start again, and that didn't solve things.

@ltalirz sorry for long delay. Please check if everything is running with docker-compose ps. The Java based services require quite some memory, which sometimes causes Keycloak to restart and makes the login endpoint unavailable.

@ltalirz looks like the keycloak service died -- we've found that this can happen if the docker daemon on mac os is not given enough memory. See the note under https://renga.readthedocs.io/en/latest/user/setup.html#prerequisites on how to fix this and then please try to restart the platform with make wipe and make start.

@jirikuncar @rokroskar Thanks for your help and my bad for overlooking this bit in the documentation. After setting the docker memory to 6GB, the problem is gone :)

I wonder:

• could there be some way of checking at the time of installation whether there is enough memory available to run the application and print a warning otherwise?
• on the web frontend, perhaps one could provide an "unreachable" error (or similar, I'm not an expert) when keycloak is not available, which would make it easier to track down the source of the problem. When I saw "internal server error" I didn't consider the possibility that the problem was just that one of the services was not running.

Anyhow, the original issue is resolved and can be closed.
