# To run properly, the directory containing the proto files Truss will read to
# generate a service must be mounted into the container, so that the output
# generated by Truss escapes the container.

# Using scratch as a base image would result in a slightly smaller image,
# which would be fine if Truss were a self-contained executable, but protoc
# has difficulty running on a scratch image. Using Alpine Linux alleviates
# these issues and only increases image size by about 5 MB.
