The Complete Practical Docker Guide - Running API Containers Based on the Built Docker Image

The video tutorial explains how to set up and test an API service using Docker containers. It covers the initial setup of the API service, creating and running Docker containers, testing the API service within the container, handling port conflicts, and managing multiple containers. The tutorial also demonstrates how to bind local ports to container ports and highlights the differences between running services locally and within Docker.

What command is used to create a new Docker container?

• docker run

• docker create

• docker build

• docker start

What is the purpose of the 'new image' endpoint in the API service?

• To update an image

• To delete an image

• To test the API service

Why does Docker return an error when trying to bind the same port for multiple containers?

• The port is already allocated

• The container is not running

• The image is not found

What does the '-P' option stand for in the Docker run command?

• Publish

• Port

How can you run multiple containers from the same Docker image?

• By using different images

• By using different local ports

• By using different commands

• By using different Dockerfiles

What happens to local files once a Docker image is created?

• They can be deleted

• They are copied to the host machine

• They are required for the container to run

• They are automatically updated

How can you check which containers are currently running?

• By using 'docker ps'
