Helm — How to Create Your Own Chart

In my last Helm article, I talked about some common helm operations and showed you how to deploy an existing sample Helm chart, this time let’s create our own Helm Chart .

At one point, you will need to create your own customized Helm Chart , because you may always find what you need in the public Helm repository.

Let’s recap the structure of a Helm Chart . The structure of a common Helm Chart looks like:

mychart/
  Chart.yaml
  LICENSE
  README.md
  values.yaml
  charts/
  crds/
  templates/
  ...

A Chart is a collection organized in file directories, where the directory name is the Chart name (without version information).

• Chart.yaml: The file contains the description of the chart
• LICENSE: Chart license file
• README.md : Readme file with additional chart information
• charts : Directories may contain other charts (sub-charts).
• templates/:A directory is used to place template files. When helm is executed, it will render all the files in this directory through the template rendering engine
• values.yaml : This file contains chart default values
