Demystifying Docker Workflow: From Blueprint to Running Containers

 Demystifying Docker Workflow: From Blueprint to Running Containers

Here’s a breakdown:

1. Dockerfile

• Acts as a blueprint to define the environment and instructions for the application.

• Use $docker build to create a Docker Image from the Dockerfile.

2. Docker Image

• A read-only, layered snapshot created from the Dockerfile.

• Use $docker run to start a container based on this image.

• Use $docker images to list available images.

• Use $docker rmi to remove unused images.

3. Docker Container

• A running instance of a Docker image.

• Use $docker ps to list running containers.

• Use $docker rm to remove stopped containers.

• Use $docker stop to stop a running container.

4. Docker Registry

• Stores Docker images for reuse and sharing.

• Push images to a registry with $docker push or pull images with $docker pull.
