question

Hi,

in addition to @jliew1975_193867's answer, here is a more complete guide to get the secure bundle imported into GitPod. I am including full steps for reference.

As outlined in the other answer, you will need to download a secure connection bundle from Astra. Refresh the page before you download, so you get a fresh and valid link. Remember where you download it to:

Then, start on the GitHub page for week3 of the workshop series:

https://github.com/DataStax-Academy/cassandra-workshop-series/tree/master/week3-AppDev-crud

Scroll down to step 3 and click the GitPod button. You will need your GitHub login to use GitPod.

Once GitPod is open (it will launch containers in the background for you, and sometimes that can take a bit of time), you get an IDE with the full project. You will now need to import the secure bundle into GitPod.

We recommend that you load it into the root of the week3 coding projects, so select this folder in the lefthand explorer panel:

Then use the File menu from the header menu to select the option to upload the secure bundle:

After the successful upload, you should see it right there in the week3-AppDev-crud directory:

Now you will need to update the connection details. I am using the python branch for this example. Update the file db_connection.py with your details: The full file path for the connection bundle, the user name, password and keyspace name. Most importantly, don't forget to save the file! There is no auto-save with GitPod.

Before you can run the examples, you will need to install the Cassandra driver. In Python you can do this with pip3 install cassandra-driver

and now you should be good to go: Navigate to crud-python directory and run python Ex02_Connect_to_Cassandra.py

This is what success looks like, complete with our string formatting error (we will fix it) :)

I hope that gets you all over the connection issues.

If you see an error about the connection not being defined, it is most likely that the details in the db_connection.py file don't match, or that the file has not been saved.

Cheers!
