name: Check for new chart dependency updates | |
# Description: | |
# This workflow automates the process of checking for and updating Helm chart dependencies. | |
# Specifically, it: | |
# 1. Checks for new versions of (subchart) dependencies listed in chart.yaml. | |
# 2. Updates chart.yaml with new versions where applicable. | |
# 3. If the 'opentelemetry-operator' subchart is updated in chart.yaml, it also updates related | |
# image tags in values.yaml. | |
