How do you build a container

Answer

We can able to create container using docker  and deploy software within containers. It’s an open source collection of tools that help us to Build, Ship, and Run any App, Anywhere. Yes, it really is as magic as it sounds.

With Docker, you create a special file called a Dockerfile. Dockerfiles define a build process, which, when fed to the ‘docker build’ command, will produce an immutable docker image. You can think of this as a snapshot of your application, ready to be brought to life at any time. When you want to start it up, just use the ‘docker run’ command to run it anywhere the docker daemon is supported and running. It can be on your laptop, your production server in the cloud, or on a raspberry pi. Regardless of where your image is running, it will behave the same way.

Docker also provides a cloud-based repository called docker hub. You can think of it like GitHub for Docker Images. You can use Docker Hub to store and distribute the container images you build.

Docker containers that run on Docker Engine:

• Standard: Docker created the industry standard for containers, so they could be portable anywhere
• Lightweight: Containers share the machine’s OS system kernel and therefore do not require an OS per application, driving higher server efficiencies and reducing server and licensing costs
• Secure: Applications are safer in containers and Docker provides the strongest default isolation capabilities in the industry
