Containerization and Docker

Explore containerization with Docker, compare monolithic and microservices architectures, embrace Unix philosophy, and learn about independent deployment and continuous integration and delivery.

Explore how Docker containerization resolves devs, testers, and ops challenges with lightweight, isolated environments; compare virtual machines with containers and learn image versus container concepts.

Run the hello world image with docker run to verify Docker installation, then explore Docker Hub, create a community account, and inspect images like Oracle, Postgres, Selenium, Mongo, and Node.
