Just a note here - this does NOT work if you are using a chart museum / packaged chart repo. There is no way to tell Helm "use the QA values file" natively using the Helm binary. You'd have to fetch, unpack and install using the -f flag to specify which environment config you want. One way around this is library charts and a separate artifact for each environment. Neither is ideal, but we went for the latter approach as it provided a bit more flexibility.
