flynn-bootstrap's Issues

flynn-bootstrap crash in run-app with default manifest: invalid memory address or nil pointer dereference

Hi,

I've set up a flynn cluster with two (I know, that a stupid size) nodes like that:

I've build flynn-host from my change here: flynn-archive/flynn-host#15 (it's on docker index as fish/flynn-host)
On both systems I ran flynn-host by pointing ETCD_DISCOVERY to discovery endpoint[1]

If I run flynn/bootstrap now (as pull from registry), I get:

$ docker run flynn/bootstrap
14:21:25.819427 run-app postgres
panic: runtime error: invalid memory address or nil pointer dereference

[1] I used ansible to deploy it, not that it matters but for completeness here is the task:


---
- name: run flynn-host
  docker:
    name: flynn-host
    image: fish/flynn-host
    env: "ETCD_DISCOVERY={{ flynn.etcd.discovery_url }}"
    volumes: "/var/run/docker.sock:/var/run/docker.sock"
    ports: "{{ ansible_int.ipv4.address }}:1113:1113"
    command: "-external {{ ansible_int.ipv4.address }} -bind {{ ansible_int.ipv4.address }}"
