I am learning to implement microservices in go from @EwanValentine website, and as such Dockerizing a set of go apps that are supposed to work like microservices connected to each other (2 at the moment). So here's my Dockerfile content:
FROM golang:1.9.0 as builder
WORKDIR /go/src/gotut/consignment-service
COPY . .
RUN go get -v -u github.com/golang/dep/cmd/dep
RUN dep init -v && dep ensure -v
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -a -installsuffix cgo .
FROM alpine:latest
RUN apk --no-cache add ca-certificates
RUN mkdir /app
WORKDIR /app
COPY --from=builder /go/src/gotut/consignment-service .
CMD ["./consignment-service"]
In the line that I'm trying to run cgo, I confront the following error. I'm not sure if it's a dep error or not, but it felt like a starting point to figure it out anyway.
Step 5/12 : RUN dep init -v && dep ensure -v

@meysam81 This comment might give some insight into solving your issue: https://github.com/golang/protobuf/issues/763#issuecomment-442767135 (You need to have the same version vendored as what is compiled into your protoc-gen-go)

You're also going to run into issues here:

strings.Builder was introduced in Go 1.10 IIRC, it's not available in Go 1.9. At the top of the Dockerfile you are using Go 1.9. Maybe try upgrading to Go 1.11.x to resolve the compile failure there.

@kevinburke Thanks man, it was helpful; and was a pain in the butt for some time.
The workaround was this:
from golang:latest as builder
Which has to be replaced in the beginning of the Dockerfile.
