FROM golang:1.15-alpine
LABEL maintainer="Me"
# Setting up Dev environment
WORKDIR /echo_app/
# note this file, go.mod exists locally. and contain reference
# to direct/indirect dependencies. this step allows to download
# dependencies and speedup build for docker images (if it used
# to build artifacts, and not as dev env).
COPY go.mod /echo_app/go.mod
RUN go mod download
EXPOSE 1323
