Running Containerized Applications using Docker on Linux

Description

In this project, we will learn about Docker containers and the benefits of these packages in deploying applications. First we will explain what are containers and the process in how they work. Then we will begin practical application with Labs walkthroughs of the various steps below:

• Installing Docker on Ubuntu Linux.
• Pulling Docker Images to Run Containers.
• Listing/Removing Images and Containers.
• Getting Secure Shell (SSH) access to a Container.
• Executing Commands in a running Container.
• Monitoring Containers.
• Committing Container changes into a New Docker Image.
• Creating Custom Images using Dockerfile.

As you can see we have an adventure ahead, LETS GET TO IT!! Enjoy!!
