In a Helm chart, how would you define a dependency on mysql version 5.6 from the repository https://mysql.helm.com/charts?

• A. - name: dependencies version: 5.6 repository: https://mysql.helm.com/charts
• B. - name: mysql version: 5.6 repository: https://mysql.helm.com/charts
• C. dependencies: - name: mysql version: 5.6 repository: https://mysql.helm.com/charts
• D. dependencies: - name: mysql version: 5.6 repository: https://charts.helm.sh/stable

Answer: (D)

Defining dependencies in a Helm chart is about listing other charts your chart relies on, inside Chart.yaml under a dependencies section. Each dependency is a YAML item that specifies the chart name, the version you want, and the repository where that chart is hosted. This structure lets Helm locate and fetch the exact dependency during installation or when you run helm dependency update.

The reason this option is the best fit is that it shows the correct dependencies block at the top level, then a single dependency entry with three fields: name set to mysql, version set to 5.6, and repository pointing to the chart repository that hosts that mysql chart. This is the proper way to declare a dependent chart: you specify which chart you want, which version of that chart, and where to find it. After adding this, you would typically run helm repo update and then helm dependency update to fetch the dependency into your chart’s charts/ directory.

Context: in Helm 3, dependencies are declared in Chart.yaml (not requirements.yaml), and the repository must be a reachable chart repository URL. The version is the version of the mysql chart you want, not the version of MySQL itself. If you need to pull from a different repository, you would replace the repository URL with the correct host and then update the repo so Helm can locate the chart.
