Helm in Practice

Linting the Chart

Linting is a pre-flight check that many developers skip, but it's an important step to ensure that the chart is well-structured and follows best practices. Helm provides a built-in linter that can be used with the following syntax:

helm lint [CHART_PATH]

We can run the linter against our todo-chart chart:

helm lint $HOME/todo-chart

The output should indicate that the chart is valid:

==> Linting /root/todo-chart
[INFO] Chart.yaml: icon is recommended

1 chart(s) linted, 0 chart(s) failed

The message [INFO] Chart.yaml: icon is recommended is just a recommendation to add an icon to the chart metadata, but it's not a requirement. If you want to add an icon, you can do so by adding the following line to the Chart.yaml
