The Basics
Docker is a code-driven server container management tool. You can use Docker with Docker Compose to simulate a network of hosted applications.
Official Docker documentation is available at the Docker Docs website.
Expansion Pack
Docker practitioners looking to expand their skills will find plenty of guidance on the official website itself. Additional pathways to knowledge expansion include technical training for numerous third party sources.
Badge Progress
Docker users begin their journey perhaps simply having heard the word container tossed around among their guild mates. Over time, they develop into true masters of the infrastructure-as-code platforming approach.
Special Achievements
Docker Certified Associate
Highly skilled Docker practitioners may wish to seek official recognition of their skills from the Docker governing body. The Docker Certified Associate designation serves as validation and confirmation of Docker learning achievements.
