What is Puppet?
Puppet is an open source configuration management and deployment tool that automate the configuration of servers. When you use Puppet, you define the desired state of the systems in your infrastructure that you want to manage. You do this by writing infrastructure code in Puppet’s Domain-Specific Language (DSL) — Puppet Code — which you can use with a wide array of devices and operating systems. Puppet code is declarative, which means that you describe the desired state of your systems, not the steps needed to get there. Puppet then automates the process of getting these systems into that state and keeping them there. Puppet does this through Puppet primary server and a Puppet agent. The Puppet primary server is the server that stores the code that defines your desired state. The Puppet agent translates your code into commands and then executes it on the systems you specify, in what is called a Puppet run.
What is the use of Puppet?
- Consistency
- Puppet allows you to define distinct configurations for every host.
- The tool allows you to continuously monitor servers to confirm whether the required configuration exists or not and it is not altered. If the config is changed, – Puppet tool will revert to the pre-defined configuration on the host.
- It also provides control over all the configured system, so a centralized change gets automatically effected.
- It is also used as a deployment tool as it automatically deploys software to the system. It implements the infrastructure as a code because policies and configurations are written as code.
