This repository builds a container that includes everything necessary to build a C++ gRPC program. The reason for this is that there are no packages for C++ gRPC, which means it must be built from source. That build can take 15-20 minutes, which is not ideal. In order to work around this, we turn to a container.
After some research, there does not appear to be an up to date containers that provide this functionality. gRPC has some docker images, but they are outdated and deprecated. See the Readme here and also this issue that has not been responded to.
