| # Purpose: Updates Helm chart dependencies and related image tags. | ||
| # Notes: | ||
| # - Automates the process of updating Helm chart dependencies in Chart.yaml and related image tags in values.yaml. | ||
| # - Specifically designed to update the opentelemetry-operator as a subchart and related instrumentation configurations in values.yaml. | ||
| # - Relies on Helm and yq tools for processing Helm charts and YAML files. | ||
| # | ||
| # Parameters: | ||
| # $1: The file path to the Chart.yaml file of the Helm chart (mandatory). | ||
| # $2: The name of the dependency (subchart) to check for updates (mandatory). | ||
| # --debug: (Optional) Activates debug mode for verbose output, aiding in troubleshooting. | ||
| # | ||
| # Usage Examples: | ||
| # ./update-chart-dependency.sh ./path/to/Chart.yaml opentelemetry-operator | ||
| # ./update-chart-dependency.sh ./path/to/Chart.yaml opentelemetry-operator --debug | ||
