If you've been messing around with Monokle or Monokle Cloud, then you've probably grown pretty familiar with YAML and Helm, after all, they are our favorite things! We love YAML, so you don't have to, but why shouldn't you? We're here to make configuring your manifests as easy as possible, and to add to the power that Monokle gives you to catch misconfigurations, we'll fill in any knowledge gaps you have about both YAML and Helm!
So, let's start off with the easy questions first:
Helm Charts are a packaging format used to deploy applications and services onto a Kubernetes cluster. They are essentially templates that describe how to install, configure, and run a set of Kubernetes resources. Helm Charts are written in YAML, just like Kubernetes manifests, but they are organized in a way that makes them easy to manage, version, and share.
YAML stands for "YAML Ain't Markup Language." It is a human-readable data serialization language that is often used for configuration files and data exchange between languages. YAML is often used in Kubernetes to define objects and their properties in a readable and concise way.
To convert a YAML file to a Helm chart, you need to create a Chart.yaml file that describes the chart and its dependencies. Then, you need to create a templates directory and move the YAML files into that directory. Finally, you need to update the YAML files to use Helm's templating syntax and replace any hardcoded values with variables. Once you have done this, you can package the chart using the helm package command and deploy it to your Kubernetes cluster using the helm install command.
By following these steps, you can easily convert a YAML file into a Helm chart and deploy it to your Kubernetes cluster.
