How do I publish service's ports?


(Xyuri) #1

I’m trying to do this:

# docker run --rm -itp 4000:80 nginx
# curl localhost:4000
<outputs welcome page>

But with Docker Compose it hangs.

docker-compose.yml:

version: '3'

services:
  nginx:
    image: nginx:stable
    ports:
      - "4001:80"
# docker stack deploy -c docker-compose.yml s1
# curl localhost:4001
<hangs>

But it does work this way:

$ curl 172.17.0.1:4001   # docker0

or

$ curl 172.18.0.1:4001   # docker_gwbridge

Is that expected behavior? Is there a way to make it accessible via localhost?

I’m running Arch Linux.
