Difference: 1. Docker is an open source application container engine and a deployment tool for the running environment; while Vagrant is a deployment tool for the development environment. 2. Docker is suitable for managing application environments, while Vagrant is suitable for managing virtual machines.

Docker

Introduction to Docker

  • Docker - HomePage
  • Overview
    Docker is an open source application container The engine is based on Go language and complies with the Apache2.0 protocol and is open source.
    Docker allows developers to package their applications and dependencies into a lightweight, portable container, and then publish it to any popular Linux machine, which can also be virtualized.
    Containers completely use the sandbox mechanism and will not have any interfaces with each other (similar to iPhone apps). More importantly, the container performance overhead is extremely low.

Docker application scenarios

  • Automated packaging and publishing of Web applications.
  • Automated testing, continuous integration and release.
  • Deploy and adjust databases or other back-end applications in service-based environments.
  • Compile from scratch or extend an existing OpenShift or Cloud Foundry platform to build your own PaaS environment.

Advantages of Docker

  • Simplify the process:
    Docker allows developers to package their applications and dependencies into one Virtualization can be achieved by publishing to any popular Linux machine in a portable container.
    Docker has changed the way of virtualization, allowing developers to directly put their results into Docker for management.
    Convenience and speed are already the biggest advantages of Docker. Tasks that used to take days or even weeks can be completed in just a few seconds under the processing of Docker containers.

  • Avoid choice phobia:
    If you have choice phobia, be a veteran patient. Docker helps you package your troubles!
    The Docker image contains the running environment and configuration, so Docker can simplify the deployment of multiple application instances. For example, web applications, background applications, database applications, big data applications such as Hadoop clusters, message queues, etc. can be packaged into a mirror for deployment.

  • Saving expenses:
    The advent of the cloud computing era frees developers from the need to configure expensive hardware in order to pursue effects. Docker has changed the mindset that high performance must be high price.
    The combination of Docker and the cloud allows the cloud space to be more fully utilized. It not only solves the problem of hardware management, but also changes the way of virtualization.

Vagrant

Vagrant Introduction

Vagrant is a lightweight, highly reusable and portable Development environment tools.

It can be simply understood that Vagrant abandons all the troublesome settings in the development environment, but replaces it with a single configuration file, and can selectively retain the required features.
Vagrant uses Oracle's open source VirtualBox virtualization system by default and uses Chef to create an automated virtual environment.

Functional features of Vagrant

  • Supports quick creation of virtual machines
  • Supports quick setting of port forwarding
  • Supports customization Image packaging (original image method, incremental patch method)
  • Basically all the basic configurations that can be used daily can be quickly set
  • Supports automatic running commands at boot
  • Yes Write your own extension

Compare Docker and Vagrant

Vagrant is based on Virtualbox’s virtual machine to build your development environment, while Docker is based on LXC (LXC) lightweight container virtualization technology.

Vagrant is the deployment tool for your development environment; and docker is the deployment tool for your running environment.

Vagrant is suitable for managing virtual machines, while docker is suitable for managing application environments.
