How do you create and run a Docker container?

Run an image by creating a container from it with docker create (mapping ports with -p), then launching it with docker start.

# Create container with port mapping
$ docker create -p 80:80 --name myweb myapp:latest

# Start the container
$ docker start myweb

Port mapping -p 80:80:

• First 80: host port (external access)
• Second 80: container port (internal)

The container is now accessible at http://localhost:80.
