undefined: grpc.SupportPackageIsVersion7 grpc.ServiceRegistrar

Question

Inside docker, it seems that I cannot compile my gRPC micro-service due to this error:

Step 4/9 : RUN make build

However, outside of Docker the thing is run and compile with success.

This is my base Docker image:

RG go_version

FROM golang:${go_version}-buster

ARG pb_version

RUN apt-get update && apt-get install -y build-essential curl git wget unzip && rm -rf /var/lib/apt/lists/*

RUN wget https://github.com/protocolbuffers/protobuf/releases/download/v${pb_version}/protobuf-cpp-${pb_version}.zip && \
        unzip protobuf-cpp-${pb_version}.zip && \
        cd protobuf-${pb_version} && \
        ./configure  && \
        make  && \
        make check  && \
        make install  && \
        ldconfig && \
        cd ../ && \
        rm -rf protobuf-*

RUN go get github.com/githubnemo/CompileDaemon && \
        go get github.com/golang/protobuf/protoc-gen-go && \
        go get github.com/grpc/grpc-go/cmd/protoc-gen-go-grpc && \
        go install github.com/golang/protobuf/protoc-gen-go && \
        go install github.com/grpc/grpc-go/cmd/protoc-gen-go-grpc

This is the Docker image where the compilation is done:

FROM registry.gitlab.com/kuecr/devops/go-protobuf-base:1.14 as base

WORKDIR /app

COPY . .

RUN make build

FROM base as testing

ENTRYPOINT ["make", "test"]

FROM base as production

RUN make build

ENTRYPOINT CompileDaemon -log-prefix=false -build="go build -o notify-service" -command="./notify-service"

My docker and docker-compose and protoc versions:

✖ docker --version && docker-compose --version
Docker version 19.03.12-ce, build 48a66213fe
docker-compose version 1.26.2, build unknown
➜ protoc --version
libprotoc 3.12.4

This is what happens when I ran make build on my machine:

➜ make build
protoc --version
libprotoc 3.12.4
protoc --proto_path=pkg/proto/notify/ --go_out=pkg/proto/notify/ --go-grpc_out=pkg/proto/notify/ --go_opt=paths=source_relative --go-grpc_opt=paths=source_relative notify.proto

plugin versions reported in *.pb.go files:
./pkg/proto/notify/notify.pb.go://  protoc-gen-go v1.25.0
./pkg/proto/notify/notify.pb.go://  protoc        v3.12.4

go build -o notify-service *.go

I'm using Golang 1.15 while the Docker image use 1.14.

Even with go get -u my version for some reason didn't get updated to the last one. I had to update google.golang.org/grpc v1.27.0 to google.golang.org/grpc v1.34.0 (latest version attow) in my go.mod manually. Then it worked.
