Integration testing your legacy java microservice with docker-maven-plugin

on YouTube ↗14m

" summary

Demonstrates using the docker-maven-plugin to start dependent containers from pom.xml in Maven’s pre-integration phase (and stop them in post-integration), binding exposed ports to random high ports to avoid collisions. Builds a test WAR, runs a Tomcat container mounting test WAR, and spins up MySQL, MinIO (preloaded buckets), Zookeeper and a mock service; runs seven integration tests via Maven Failsafe (≈1 minute), but loses code coverage measurement.
