Docker 1.5.0 has issues with iptables

thisgeekza · February 18, 2015, 6:13am

I just upgraded docker to 1.5.0. Since then I have been unable to bootstrap the web container.

$ sudo ./launcher bootstrap web

Downgrading to docker 1.4.1 allows web to bootstrap. Oddly enough, data can bootstrap with 1.5.0, but web won’t.

did you reboot post installation, I have been using docker 1.5 on about 15 machines now and it works just fine.

thisgeekza · February 18, 2015, 10:53am

Yes, I did.
Not sure what the issue is, but have rolled back for the time being.

I even tried removing all the discourse related images, and let launcher re-pull them.

thisgeekza · February 18, 2015, 11:46am

Damnit, sorry. The container is built from web_only.yml, not the standalone, if that makes any difference.

codinghorror · February 18, 2015, 5:49pm

Yeah no issues with Docker 1.5 at all here.

thisgeekza · February 18, 2015, 6:01pm

Damn. Then I don’t know what is different about my system that I’m having issues suddenly. It’s a bog standard ubuntu server 14.04 LTS install.

sam · February 18, 2015, 7:58pm

what does docker info return ?

thisgeekza · February 19, 2015, 3:32pm

The one thing that is non-standard about my docker install, is that I don’t like it opening up my containers to the world, so I have added DOCKER_OPTS="--icc=true --iptables=false" to /etc/default/docker.
I then manually add iptables rules to allow the containers to communicate out. I don’t think this is causing the issue with the container not starting or even bootstrapping on 1.5.0 though. Everything works just fine on 1.4.0.

I’m a bit stumped with what’s going on here.

If nobody can give see any issues with what I’m doing, I’ll try set the daemon to default startup params and see if it’s still having an issue. Last resort will be to upgrade the OS to 14.10 and see if it makes any difference.

This is what happens after upgrading docker to 1.5.0 and rebooting:

There’s your failure. It’s the launcher following this part of the config:

## which TCP/IP ports should this container expose?
expose:
  - "80:80"   # fwd host port 80   to container port 80 (http)
  - "2222:22" # fwd host port 2222 to container port 22 (ssh)

thisgeekza · February 20, 2015, 5:36am

I have 4 containers in total, 3 of them start up and run with no issues. All of them have exposed ports.

riking · February 20, 2015, 6:22am

Well, it’s definitely the automatic iptables causing the issue.

Or maybe you added some forwarding rules yourself?

Quoting the relevant part of the log, one whole Docker API request:

Thanks, you are correct. It is that causing the issue.

I removed my DOCKER_OPTIONS to revert it back to default, upgraded back to lxc-docker-1.5.0 and everything works.

Happily, it seems that docker has fixed the annoyance of messing with iptables and exposing all the containers to the wide world, so I no longer need to mess with the DOCKER_OPTIONS and my own iptables rules!

Thanks for everybody’s time and input in this thread, I really appreciate it.
