I followed this guide. (I’m on CentOS 7.): http://www.howtoinstalldiscourse.com/how-to-install-discourse-on-centos/ When I try and run the command /var/docker/launcher start app I get this error: which: no docker.io in (/sbin:/bin:/usr/sbin:/usr/bin) Device "docker0" does not exist. 2014/12/12 14:41:50 Cannot connect to the Docker daemon. Is 'docker -d' running on this host? Cannot connect to the docker daemon - verify it is running and you have access PLEASE HELP! Miles

Welcome to my world. I had the same issue when trying to do a local setup. I forgot how I got passed this one, but in my case (I was doing an Ubuntu install) I ultimately gave up and downloaded an ISO with Docker and Discourse pre-installed for a local test than got a Digtialocean droplet to run a real test on. The guys here are pretty helpful so hopefully someone can get you going where I failed, but let me know if you need that image :smile:

I hope so. And I hope soon. I have to go in a few minutes here, and I was going to let it run whilst I’m gone.

Can you walk me through it? Like how to install it properly? (Thanks in advance.)

I know. But I have Centos 7, and I can’t find a tutorial that works without an error. ;p.

Ok, so now I’m getting this error. which: no docker.io in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/ bin) which: no docker in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin ) Device "docker0" does not exist. info: Writing node (dir)Top... info: Done. Your Docker installation is not using the recommended AuFS (union filesystem) an d may be unstable. If you are unable to bootstrap / stop your image please report the issue at: https://meta.discourse.org/t/discourse-docker-installation-without-aufs/15639 ./launcher: line 99: --version: command not found ERROR: Docker version not supported, please upgrade to at least 1.2.0, or recom mended 1.2.0 All I did was yum install docker (I’m on Centos 7) Can you just send a link to a tutorial?

I don’t have one.. my recommendation is to drop CentOS and use Ubuntu Server, following our standard install guide. It’s all the same Linux underneath anyway. Here is how you install Docker (logged in as root) in our guide: wget -qO- https://get.docker.io/ | sh

Error when I do wget -qO- https://get.docker.io/ | sh Either your platform is not easily detectable, is not supported by this installer script (yet - PRs welcome! [hack/install.sh]), or does not yet have a package for Docker. Please visit the following URL for more detailed installation instructions: https://docs.docker.com/en/latest/installation/ y u no work launcher

And I can’t. My other dev uses it. Probably gonna buy the $5/mo here. If I just run Discourse on that, (with all of it’s requirements) and Ubuntu, will it work smoothly? Budget-Friendly Cloud Server Pricing | DigitalOcean

Docker isn’t properly installed on your OS.
