Docker for the Brave
The document introduces Docker and its ecosystem, highlighting the need for containers to bridge the gap between development and production environments. It explains the basic workflows, container lifecycle, and the advantages of using immutable containers for improved stability and reduced human error. The presentation also discusses container networking, persistent volumes, and delves into more complex scenarios using docker-compose for managing dependencies.
