Vagrant and docker

This document discusses Vagrant and Docker as choices for development environments. It covers why virtualization is needed for development environments, how Vagrant and Docker each work, and how each can be used. Vagrant allows creating and managing virtual machines, while Docker uses containers. Both can standardize environments and development workflows. Vagrant may be better for standardizing full development environments, while Docker is better suited to standardizing app deployment in CI/CD pipelines and production.
Vagrant and docker
- 1. Vagrant or Docker Choice for development environment
- 2. Agenda • Why • Vagrant Usage • Docker Usage • Next step
- 3. 为什什么研发环境虚拟化 • 痛点 • 操作系统不不⼀一致 • 编译环境不不⼀一致 • 运⾏行行的容器器等不不⼀一致 • 外部依赖 • It works on my PC • 理理想的研发流程 • 获取源代码 • 运⾏行行代码 • 修改代码 • 运⾏行行／调试代码
- 4. 研发虚拟化选择 • Vagrant • A Virtual Machine • All in one VM • Share Code Folder • Ports forward • Edit Code outside • Run app in box • Docker • A Container • one container for one app • git style modification • Docker compose • Copy on volume share • Ports forward
- 5. VM vs Docker
- 6. Vagrant usage • Building box • Building an VM by Virtualbox/VMWare • Convert to vagrant box: vagrant package • Set the vagrant env: Vagrant init • Customize VagrantFile • start the VM: vagrant up • SSH to the VM: vagrant ssh • Explore the code …
- 7. Docker Usage • Build images • DockerFile/Docker Pull • Docker commit • Docker push • Docker run • docker images • docker ps / docker kill
- 8. Next Step • 标准化／虚拟化研发环境两者都可⽤用 • Vagrant box可以防在任意http服务器器上 • Docker Image需要上传到Docker Hub（public／internal） • Vagrant 在标准化研发环境更更适合 • Docker更更适合标准化发布(CI & Production) • 两者可以结合起来使⽤用
- 9. Let’s try and make your choice
