title: Need guidance for creating temporary docker container for generating file on host machine
body: <p>I'd like to create a docker container that can read file named <em><strong>helloworld.proto</strong></em> and run  command</p>
  <p><code>protoc --dart_out=grpc:lib/src/generated -Iprotos protos/helloworld.proto</code></p>
  <p>The container would start with all the dependencies and generate required file using gRPC which is accessible by the HOST machine. Is this achievable?</p>
