devops-consul: A Ruby repository from Cinderhaze

devopsstc consul talk
----------------------

Started by getting Consul running in a few hand-created vagrant instances, bootstrapped using puppet.

I tried to look for a more lightweight way of doing it... docker?

Right now I'm working though
http://jlordiales.me/2015/02/03/registrator/

I'm trying to run docker from inside the VM, and I don't have a route to any registry..

core@host-2 ~ $ docker run --rm progrium/consul cmd:run 172.28.128.3 -d -v /mnt:/data
Unable to find image 'progrium/consul' locally
Pulling repository progrium/consul

Sam looked at it, and was seeing the same issue, it may be a problem with the coreos base image.  I'm going to try replacing the image with the base image used by boot2docker and see if it fixes it.  


I had the same issue manually loading the boot2docker image in.. giving up and following advise here now

So, I stood up a mysql container on dev-1
If I run the command from dev-3 listed in the exale, I get.
