i have a tricky problem for a while with the new swarm mode.
I simply try to run a go web server in the first and a mongo db in the second container. Therefor I am using a private test image and the standard mongo image. Calling the mongo service on port 27017 works. The go run main.go command runs in the test service. I Expose: 8080 in the Dockerfile. Additionally ports: "4444:8080" is set for the go service (users, test image).
Dockerfile:
1 FROM crypvert-base:latest

3 ADD . /go/src/test
4 WORKDIR /go/src/test

6 RUN go get -d -v
7 RUN go install test
8 ENTRYPOINT /go/bin/test

10 EXPOSE 8080

11 image: mongo:latest
users/bootstrap.go
8 func Bootstrap() {
10 e := echo.New()
19 e.Logger.Fatal(e.Start(":8080"))
20 }
$ docker service inspect --pretty test_users
