What is Docker?Docker là gì?

So what Docker is?

Docker allows you to package an application with all of its dependencies into a standardized unit for software development.

Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server.

This guarantees that it will always run the same, regardless of the environment it is running in.

What is a Container?Container là gì??

is a set of processes which have been isolated together by the Linux kernel

Developer: Build Once, Run Anywhere

● A clean, safe, hygienic and portable runtime environment for your app.● No worries about missing dependencies, packages and other pain

points during subsequent deployments.● Run each app in its isolated container.● Automate testing, integration, packaging...anything you can script● Reduce/eliminate concerns about compatibility on different platforms,

either your own or your customers.● Install replay and reset of image snapshots.● Almost no overhead (think about VM).

DevOps: Configure Once, Run Anything

● Make the entire lifecycle more efficient, consistent, and repeatable.● Increase the quality of code produced by developers.● Eliminate inconsistencies between development, test, production,

and customer environments.● Support segregation of duties.● Significantly improves the speed and reliability of continuous

deployment and continuous integration systems.● Because the containers are so lightweight, address significant

performance, costs, deployment, and portability issues normally associated with VMs.

Dockerfile

A Dockerfile is a text document that contains all the commands a user could call on the command line to

assemble an image.
