[rancher-compose] Failed to create circular links in services

[JamesBarwell]

RancherOS: v0.4.0-rc2
Rancher: v0.32.0
Cattle: v0.75.0
User Interface: v0.40.0
Rancher Compose: v0.2.5

Description

I have two services that link to each other, described in the docker-compose.yml. I build them using rancher-compose.

Expected

Two services are created with links to each other.

Actual

Only one of the services links to the other, and I receive a warn in the rancher-compose output.

Details

Two services defined:

foo:
  restart: always
  tty: true
  image: tutum/hello-world
  stdin_open: true
  links:
    - bar:bar

bar:
  restart: always
  tty: true
  image: tutum/hello-world
  stdin_open: true
  links:
    - foo:foo

foo:
  scale: 1

bar:
  scale: 1

and I build them:

rancher-compose -f test/docker-compose.yml -r test/rancher-compose.yml create
INFO[0000] Creating environment test
INFO[0000] Creating service foo
WARN[0000] Failed to find service bar to link to
INFO[0000] Creating service bar

The services show up in the GUI with only bar linking to foo, and foo having no links. But the order seems to be random and quite often I see bar linking to foo, and foo linking to nothing. If I add the missing link using the GUI, it does appear successfully.

Is this functionality supported? Cheers.

I've just been pointed towards issue #1851, which perhaps I've duplicated here. If I simply 'up' the service without building, I still get the warn in rancher-compose, however the service does come up with the correct link.

rancher-compose -f test/docker-compose.yml -r test/rancher-compose.yml up
INFO[0000] Creating environment test
INFO[0000] Project [test]: Starting project
INFO[0000] Creating service foo
WARN[0001] Failed to find service bar to link to
INFO[0001] [0/2] [bar]: Starting
INFO[0001] Creating service bar
INFO[0013] [1/2] [bar]: Started
INFO[0023] [2/2] [foo]: Started

Yes that is the same issue; please track it for updates.
