Where Subcharts Come From
Chart.yaml lists a dependency on redis 19.x from a repository URL. helm install app . fails with "found in Chart.yaml, but missing in charts/ directory". What fixes it?
Chart.yaml
redis
helm install app .
Choose one answer
helm repo update, because install downloads dependencies from the repo cache.
helm repo update
helm install app . --dependency-update is the only option. There is no separate command.
helm install app . --dependency-update
helm dependency update ., which downloads the subchart archive into charts/ and writes Chart.lock.
helm dependency update .
charts/
Chart.lock
Copy the redis chart's values into values.yaml.
values.yaml
