Molecule Testing for Ansible-Driven Data Lake Deployments on Kubernetes
summary
Shows how Molecule runs automated Ansible tests against Vagrant/VirtualBox instances to build a six-node Kubernetes cluster on a single VM, provisioning master and worker nodes, Calico, Ingress, local-path storage and Helm, then deploys Elasticsearch, Kibana, JupyterHub, Spark and Airflow. Demonstrates creating Molecule scenarios, Molecule idempotence check, prepare scripts for networking/NFS and HAProxy, and verify playbooks that assert cluster health — tests run end-to-end and return Elasticsearch cluster status green.
