In production, you need to change the storageClassName: hostpath to gp2 (or whatever you’re using). We used persistence volume to save notebooks.You can use IAM roles & policies that are usually associated with Kubernetes service accounts. In production, you will need to give S3 access permissions for both jupyter and executors.Make sure your notebook is exposed only within your VPN and remove the empty token from the CMD. We disabled the Jupyter-notebook’s authentication for this tutorial.We used root user for simplicity, but the best-practice is to use non-root user in production.The following configurations were added for local work (with localstack): .=true .=false.In production, change the authentication provider to either WebIdentityTokenCredentialsProvider or SimpleAWSCredentialsProvider. We used AnonymousAWSCredentialsProvider for accessing local S3.Data Scientists can select the version of Spark to be. Failures might leave Spark executors running which consumes redundant resources. In Cloudera Machine Learning (CML), multiple Spark versions are available through Runtime Addons. The application is wrapped within try/except block as in case of application failure, we want to ensure that none of the executors keep running.We will also use a cool sparkmonitor widget for visualization. Apache Spark is a popular engine for data processing and Spark on Kubernetes is finally GAIn this tutorial, we will bring up a Jupyter notebook in Kubernetes and run a Spark application in client mode. Be aware that there are several actions that need to be taken before proceeding to the production environment (especially in terms of security). Jupyter notebook is a well-known web tool for running live code. I hope that this tutorial could help you to move forward to production. Now run this notebook and you’ll see the results! Observations The JupyterHub Helm chart lets a user create a reproducible and maintainable deployment of JupyterHub on a Kubernetes cluster in a cloud environment.
