I have a Dockerfile which I can successfully build an image from:
FROM iron/go:dev
RUN mkdir /app
COPY src/main/main.go /app/.
# Set an env var that matches your github repo name, replace treeder/dockergo here with your repo name
ENV SRC_DIR=/app
# Add the source code:
ADD . $SRC_DIR
# Build it:
RUN go get goji.io
RUN go get gopkg.in/mgo.v2
RUN cd $SRC_DIR; go build -o main
ENTRYPOINT ["/app/main"]
However, when I attempt to build the following docker-compose.yml file:
version: "3.3"
services:
api:
build: ./api
expose:
- '8080'
container_name: 'api'
ports:
- "8082:8080"
depends_on:
- db
networks:
- api-net
db:
build: ./db
expose:
- '27017'
container_name: 'mongo'
ports:
- "27017:27017"
networks:
- api-net
networks:
api-net:
driver: bridge
I get:
Removing api mongo is up-to-date Recreating

I suspect that docker-compose is introducing some nuance when it comes to directory build paths, however, I'm at a loss as to why my image is building from the docker file when using docker build ., but failing when I try to incorporate this into docker-compose.
Can someone point me in the right direction as to what I am doing wrong?
I've upgraded to the latest version of Docker CE (18.03.1-ce, build 9ee9f40) and this appears to have resolved the issue.
