datastax-academy / cassandra-workshop-series Goto Github PK

In the text:

We will create a Kubernetes cluster based on the following configuration 1 master, 5 workers to be able to spawn some multi nodes clusters.

The URL link for "following configuration" currently is:

https://github.com/DataStax-Academy/cassandra-workshop-series/blob/master/week5-Cass-in-k8s/01-kind-config.yaml

which resulted the 404 error.

I believe you meant to say:

https://github.com/DataStax-Academy/cassandra-workshop-series/blob/master/week5-Cass-in-k8s/setup-your-cluster/01-kind-config.yaml

My 2 cents!

Not sure if the java week3-AppDev-crud/crud-java/target content has been intentionally committed to the repo. If not could this be removed?

Optional

Step 3f of README_CASSANDRA.MD states:

cqlsh cluster1-dc1-service.cass-operator -u cluster1-superuser -p XXX

It should just be:

cqlsh cluster1-dc1-service.cass-operator -u cluster1-superuser -p XXX

I got an authentication error when Cassandra is local, with USE_ASTRA=false.

Trying to figure out a solution I created a fork and added some code, as shown below:

bampli/t1-astra@4cd61c5

The idea was to fulfill Cassandra security requirements but still got an error:

Any hints? How to connect with local Cassandra cluster with Kind?

The cloud instances we've provisioned to Workshop participants is locked down for security reasons and port 5000 cannot be used for the week 6 exercise. We need to deploy a workaround so participants can proceed with the exercises.

When I try to run week4-python I got an error, as the 'controller' package could not be located. What am I doing wrong?

Steps:

• goto Gitpod
• pip install Flask flask-cors cassandra-driver
• FLASK_ENV=development FLASK_APP=getting_started_with_astra.py flask run

Result:
gitpod /workspace/getting-started-with-astra-python $ FLASK_ENV=development FLASK_APP=getting_started_with_astra.py flask run
