Overview
The requirements.yaml file was deprecated in Helm 3 and replaced with the Chart.yaml 'dependencies' element.
requirements.yaml is an optional metadata file that contains the immediate dependencies for the chart, expressed as a list of chart "coordinates": name, version and repository URL. Note that the immediate dependencies might have dependencies on their own, which are not explicitly specified in the chart's requirements.yaml file, but implied. For an in-depth discussion on how Helm dependencies work, see:
Structure
dependencies: - name: blue version: 1.2.3 repository: http://example.com/charts alias: something condition: something.enabled, global. something.enabled tags: - front-end - big - name: green version 3.2.1 repository: http://another.example.com/charts
Example
dependencies:
- name: postgresql
version: 6.3.2
repository: https://kubernetes-charts.storage.googleapis.com
requirements.lock
Fields
name
The dependency chart name. The name must match the name in the chart's Chart.yaml file.
version
The dependency chart version. It could be a version or a version range.
repository
The dependency chart repository full URL.
The most common case is to specify an on-line repository, as such:
- name: postgresql
version: 6.3.2
repository: https://kubernetes-charts.storage.googleapis.com
In this case, helm repo add must be used to add the repository locally before using the dependent chart.
However, we can refer to dependencies that exist on the local filesystem, using an absolute path file URL or a relative path URL, as such:
- name: my-chart
version: 1.0.0
repository: file:///tmp/charts/my-chart
- name: my-chart
version: 1.0.0
repository: file://../my-chart
Note that when a relative path is used, it is considered relative to the dependent chart root directory.
In case the dependency chart is not archived, but exist as an exploded directory on the file system, the file:// URL must point to the root directory of the chart - the one that contains Chart.yaml.
If the dependency chart is retrieved locally, it is not required to have the repository added to helm by helm repo add.
