Docker Images and Containers
Section titled “Docker Images and Containers”An image is the packaged blueprint. A container is the running instance created from that blueprint.
Why The Distinction Matters
Section titled “Why The Distinction Matters”- images are built once and reused many times
- containers are disposable runtime units
- debugging, deployment, and persistence decisions change depending on which layer you are dealing with
Understanding this difference is foundational for reliable Docker usage.
