Hi there 👋

This blog post talks about Automation using Puppet, which are generally used to fetch the status of the app servers before the actual deployment.
Puppet is a pull-based automation tool and an end-to-end configuration management tool that communicates via SSL encrypted connection between the server and client. Puppetarchitecture mainly consistsof a Puppet server and Puppet client. When we run a configuration in the Puppet server, we can deploy that configuration to multiple Puppet agent servers.
Puppet server Includes:-
Puppet client Includes:-
Modules are used for end-to-end configuration to specify all things the agent server has to deploy.
The Puppet server is the place where we store manifests and the modules. Manifests are the end state server description.
Hiera is the key-value store that we can feed into the module later. It contains the catalog, which is the mapping of the manifests.
The Puppet agent collects the information of the Puppet agent itself and sends that to the Puppet server. Then it requests a catalog that specifies which module needs to implement on which server. When the catalog is received, the agent ensures the server is in the matching state particularized in the catalog. After implementing the modules in the agent server, it sends back a report to the Puppet server that describes all the applied settings.
It is a PostgreSQL database that collects additional data-consuming Puppet setup and any of the running Puppet nodes. It is available in both Puppet open source edition and Puppet enterprise edition.
However, the Puppet enterprise edition is featured more than the Puppet open source edition.
DB usually fetches the matrix about the nodes running the Puppet agent in the Puppet. Using this Puppet DB, we can store the reports about the deployment of the modules and the manifests and the configurations applied to the node.
