My current situation is that there are multiple APIs and frontends as part of one package. Currently, the CI pipeline builds the docker container and pushes it to a repository, tagged with the build number.

I am currently trying to produce a Helm chart as part of each build. When packaging the chart, I can use "helm package --app-version XXXX" to use the build number for this chart but I don't know how I'd change the value of the tag to use based on the build number.

My end goal is to have a separate repository which contains just a Helm chart to encompass the subcharts with the build numbers of each of the components and release that as a specific version. So the main chart would be 1.0.0 and the subcharts would be versioned based on their builds.

My questions are: 1. Is it possible to change the values in a chart before publishing it? If so, how would I go about doing it? 2. Does this approach sound good for CI/CD and a Microservice style architecture?

Thanks, James
