semantic-release-helm

This is a plugin for semantic-release. It updates version and appVersion of a Helm chart's Chart.yaml.

The version is increased according to nextRelease.type, which can be one of

• major
• premajor
• minor
• preminor
• patch
• prepatch
• prerelease

or null if it's not valid.

The appVersion is set to nextRelease.version.

Examples:

version 0.1.0  
appVersion 1.16.0

1. patch (1.16.0 -> 1.16.1)
   New chart version is 0.1.1

2. minor (1.16.0 -> 1.17.0)
   New chart version is 0.2.0

3. major (1.16.0 -> 2.0.0)
   New chart version is 1.0.0

Configuration

• path (required)
  Chart directory, where the Chart.yaml is located.

• registry (optional)
  URI of a container registry.

Pass credentials through environment variables accordingly:

export REGISTRY_USERNAME=<USERNAME>
export REGISTRY_PASSWORD=<PASSWORD>

Example

This will update versions in ./chart/Chart.yaml and push the chart to localhost:5000/repo/chart. The image will be tagged with the value of version from Chart.yaml.
