Module "github.com/ZhangZhihuiAAA/zgrpc-go-professionals/proto" doesn't exist in Github.
Solution:
Step 1: Change the import statements, using local packages instead of remote github packages.
Step 2: Merge the three modules server, client and proto into one module.
Step 3:
In todo.proto:
package todo.v2; ...... option go_package = "zgrpc-go-professionals/pb/todo/v2";
In go files:
pb "zgrpc-go-professionals/pb/todo/v2"
In Dockerfile:
# generate code out of proto files
WORKDIR /go
ENV MODULE=zgrpc-go-professionals
RUN protoc --go_out=src \
--go_opt=module=$MODULE \
--go-grpc_out=src \
--go-grpc_opt=module=$MODULE \
src/proto/todo/v2/*.proto
