Of course, first just check if the Kubernetes Pods are showing up and are running. See Troubleshooting for some ideas how to investigate problems.

Once the services are running, there are very basic tests to check if they return some information:

helm test cocalc

(where cocalc is the name of your CoCalc OnPrem deployment). This starts a few Kubernetes Jobs and checks if they succeed.

Beyond that, a good end-to-end test is to

  • Open the website, sign in as admin, and go to your projects.

  • Open a project of yours, or create one.

  • Open or create a terminal.term file and run basic Linux commands like uptime or htop.

  • In that terminal, check if CoCalc related environment variables make sense: $ env | grep -i COCALC.

  • Open or create a Jupyter Notebook, select a popular kernel like “Python 3” and eval a cell with code like:

    import sys


    import pandas as pd
    df = pd.DataFrame({'a': [1, 2, 3], 'b': [4, 5, 6]})
    • Similar for R, Octave and Sage (if installed).

    • For Sage, make sure evaluating code works. If it doesn’t, try running sage in a Terminal and if you get an “ILLEGAL INSTRUCTION” error, that means your hardware is too old for the Sage binary. Contact us.

  • Create a latex.tex document and check if it compiles.

  • Once some files are opened in your project, hit the refresh button of the browser. The files should still be there after reloading them, ready to be edited.
