Containers #101: Docker ONBUILD Triggers & Introduction to Docker Compose

The Containers #101 online meetup covered Docker ONBUILD triggers, explaining their functionality and usage, and included a demonstration of running a mini microservices application by linking containers using environment variables and the `-e` flag in the `docker run` command. Attendees were provided with both the slides and a full recording of the session, available on the Vimeo channel. The code for the microservice application is accessible on GitHub, and participants were encouraged to share comments or questions via email or during future meetups.
