Summary

Dependencies can greatly reduce the effort required to deploy complex applications in Kubernetes. As we saw with our guestbook chart, to deploy a Redis backend, we only needed to add five lines of YAML to our Chart.yaml file. Compare this to the effort required to write an entirely separate Redis chart from scratch, which would have required both a high level of Kubernetes and Redis expertise.

Helm dependency management supports several different configurations to declare, as well as configure dependencies. To declare a dependency, you can specify the chart’s name, version, and repository under the dependencies map in the Chart.yaml file. You can allow users to toggle whether to enable or disable each dependency using the condition and tags properties. When incorporating multiple instances of the same dependency, you can use alias to provide each with a unique identifier, and when working with dependencies with complex values, you can use import-values to simplify...
