Docker Images vs Containers

Docker images are read-only templates used to build containers. Containers are deployed instances created from those templates. Images and containers are closely related, and are essential in powering the Docker software platform.

Docker Use Cases

1. Dev/Prod Parity: When you want the code, environment, software version(s) everything same at both dev and prod
2. Avoid Configuration headache
3. Code Pipeline Management
4. Developer's Productivity
5. App Isolation: for microservice, avoid DDoS
