Add services needed by apps to /etc/hosts #240

Closed jbardin closed 9 years ago

jbardin commented 9 years ago

The docker --add-host option put entries into the /etc/hosts inside the container. Use this instead of the dnsmasq resolver with the *.galaxy zone.

Can this be done dynamically after the container has started? Otherwise it could be an issue if two services are interdependent.

jbardin commented 9 years ago

*.galaxy always resolves to the external IP of the local host (it gets redirected through shuttle), so IPs shouldn't need to change.

I think one could technically exec into the running container and modify /etc/hosts if needed, but apps should generally know what other services they will depend on for the lifetime of that particular version.

no clean way to do this currently, but we can bundle it with replacing the storage backend
