2015.5月份新課程​Learning DevOps by Puppet/Vagrant: Rapid environment deployment and configuration management

​The key challenge of system deployment and configuration are –

• Setup and configure your production environment and keep system changes consistency among all servers is a nightmare?
• Sharing VM image to stakeholders for testing can be time-consuming to copy the VM file whenever there is little change in the VM.
• Production environment configurations changes or module installation for 10+ nodes. Any more efficient way?
• How to keep change history of what configuration changes, installed modules, what service or files changes?
• l   You have a new team member. It takes time for all the software and services needed to run the project on their machine?
• “It works on my machine!.” You encounter the issue which can’t reproduce on other environment while you don’t know how to keep the testing/developing and production environment consistency?

Puppet/vagrant can do –

• Maintain system configuration changes in simple plain text
• Automatically install multiple servers with the expected configuration/installed service from scratch automatically within 30 min.
• Puppet can automate the installing and configuring MySQL or Apache and so on with pre-defined plain text system changes file.
• Keep Virtualized environment update-to-date as project changes and to share with colleagues easily.
• What you will learn?
• We will learn from scratch to be familiar with how the tools (puppet/vagrant) can help.
• Hands-on tutorials by several case study
• Define your own system configuration/installation changes file (puppet scripts called manifests).
