Helm in Practice

Using a Chart with a Custom Configuration File

If you have one or two configurations to define, using the --set flag is a good option. However, if you have tens of values to change, the --set flag can become cumbersome and error-prone. In such cases, it's better to create a custom configuration file (e.g., values.yaml) and use the --values flag to specify it during installation.

helm upgrade -i [RELEASE_NAME] [CHART] --values values.yaml

In our case, if we want to achieve the same configuration as before using a custom values.yaml file, we can create the file with the following content:

cd $HOME && cat < values.yaml
service:
  type: LoadBalancer
  ports:
    http: 8000
