A Docker lab that starts with one command, end-to-end tested, to learn full-text search with Elasticsearch and OpenSearch, Kibana dashboards, and Neo4j graphs in Cypher — on the same dataset, with every query verified and an entire lesson devoted to troubleshooting.
Supervise a running application on your machine using Prometheus, Alertmanager, Grafana, Loki and Alloy in Docker Compose, around a fully instrumented API. Metrics, PromQL, dashboards, correlated logs, working alerts, and a final project. Every command followed by real output, a guided practice per module, and a tested GitHub kit.
