Docker image does not work

[ghost]

I tried to setup a container running letmegrpc, with the following Dockerfile

FROM golang:latest

# install protobuf
RUN apt-get update && apt-get install curl unzip -y 
RUN curl -OL https://github.com/google/protobuf/releases/download/v3.0.0/protoc-3.0.0-linux-x86_64.zip \
  && unzip protoc-3.0.0-linux-x86_64.zip -d protoc3 \
  && mv protoc3/bin/protoc /usr/bin/protoc

# install letmegrpc
RUN cd $GOPATH \
  && mkdir -p ./src/github.com/gogo/letmegrpc \
  && git clone https://github.com/gogo/letmegrpc ./src/github.com/gogo/letmegrpc \
  && git clone https://github.com/gogo/protobuf ./src/github.com/gogo/protobuf \
  && go get google.golang.org/grpc \
  && go get golang.org/x/net/context \
  && (cd ./src/github.com/gogo/letmegrpc && make install)

# install protoc-gen-gogo
RUN go get github.com/gogo/protobuf/protoc-gen-gofast \
  && go get github.com/gogo/protobuf/proto \
  && go get github.com/gogo/protobuf/jsonpb \
  && go get github.com/gogo/protobuf/protoc-gen-gogo \
  && go get github.com/gogo/protobuf/gogoproto

COPY protos /etc/protos

EXPOSE 5000

CMD letmegrpc --addr=localhost:3002 --port=5000 --proto_path=/etc/protos /etc/protos/auth.proto

I tried to run it using docker run -it -p 5000:5000 letmegrpc:auth, The process run without any errors, but http://localhost:5000/MyService/MyMethod still cannot be reached, any idea where the issues are? Thanks in advance!

Hmmm, I should have done this a long time ago. Great idea.

Would you mind trying rather using the customized work flow https://github.com/gogo/letmegrpc#customization

It requires a little extra work, but using the letmegrpc command is just a small hack just to quickly show you have it could work. Here you can see it calling the protoc commands as well https://github.com/gogo/letmegrpc/blob/master/main.go#L92-L93 followed by the hackily generated main.go file to hook everything up.

Maybe you could also first try expose 3002 and maybe make -addr=0.0.0.0:3002? But that is just my noob docker guess.

Thanks for the response! It ends up been an issue on my local machine, the image worked after I restart my local machine

That is great news. Thanks for letting us know and now we have a docker recipe as well. Thanks so much :)
