Chef is a configuration management tool that can be used to automate the process of making changes and deploying applications.
To handle changes and deployments with Chef, you can use the chef-client command to deploy the changes to your nodes. The chef-client command will run a series of recipes that are defined in the Chef cookbooks. The recipes can be used to install packages, configure services, and deploy applications.
For example, let’s say you want to deploy a web application to your nodes. You can create a cookbook that contains recipes to install the web server, configure the web server, and deploy the web application. Once the cookbook is ready, you can use the chef-client command to deploy the changes to your nodes. The chef-client command will run the recipes in the cookbook and deploy the web application to the nodes.
