Upgrade to Docker 1.8.x

[lox]

It seems like the amazon-ecs-agent is relying on Docker 1.6.2 (although recommends 1.7.1??).

Are there any roadblocks to upgrading to a more recent version?

Hi @lox, where are you seeing a reliance on Docker 1.6.2? The Agent should work well with Docker 1.5.0 through Docker 1.7.1. I'd expect that it will work fine with Docker 1.8.2 as well, but we have not completed testing with that version.

In terms of the dependency, I was just talking about the fact that the docker 1.6.2 libraries are linked against. Trying running it from source now.

Ugh, apologies, this is a systemd-docker issue. ibuildthecloud/systemd-docker#33
