example-chart

Sample Helm chart for an application with one HTTP interface (e.g., a website).

Copy chart and change:

• In Chart.yaml, edit metadata such as name, description, keywords, sources, and maintainers.
• In values.yaml, edit at least image.repository and image.tag.
• Optionally, if the image is listening on a port other than 80, edit the container port.

All defined template names start with app. which should be changed to a unique name (app name) with:

find chart/templates/ -type f -exec sed -i s/\"app\\./\"UNIQUE_NAME./g {} +

Features:

• Templating with toYaml, always. Prevents confusion of variable types.
• Alphabetical order of keys, but name always comes first.
