Ansible playbook to keep a Rancher container running on a docker host

I am merely following the instructions at this [link] (https://github.com/rancherio/rancher) , and ensuring the rancher/server container is started properly you can then use ansible to maintain containers, ansible docs here

Quick Start from installing RancherOS

Append the example hosts to your ansible hosts file

cat hosts>>/etc/ansible/hosts

Now replace $IPADDRESS and $PORT in that file as necessary

now enable the ubuntu-console, if you did not do so in cloud-config

make console

then bootstrap python for ansible to function:

make bootstrap

Note: this may hang, ctrl-C if it does, and test:

make ping

Then you can

make server

and

make agent

detailed usage

add these lines to /etc/ansible/hosts or wherever you keep your inventory similar to: For the host that runs the rancher server

[rancherserver]
rancherserver ansible_ssh_port=$PORT ansible_ssh_host=$IP_ADDRESS ansible_ssh_user=root

For the hosts that run the rancher agents

[rancheragent]
rancheragent ansible_ssh_port=$PORT ansible_ssh_host=$IP_ADDRESS ansible_ssh_user=root

For the hosts that run the rancherOS,

[rancheros]
rancheros ansible_ssh_port=$PORT ansible_ssh_host=$IP_ADDRESS ansible_ssh_user=root

you need to get each of the RancherOS VMs them running the ubuntu-console, log into each and sudo ros service enable ubuntu-console; or you can call the console playbook directly like so

ansible-playbook rancherOSubuntuconsole.yml

or make console to set the ubuntu console in all your rancherOS images (needed for ansible to run)

and then you’ll need to install python, make bootstrap, then get the server up

ansible-playbook rancherServer.yml

or use make server, once the server is running get auth setup and add a host you’ll get something like:

sudo docker run -d --privileged -v /var/run/docker.sock:/var/run/docker.sock rancher/agent:v0.7.8 $URL

where $URL is a big long url that points at your rancher server, run make agent and you will be prompted for your url, or make a file url and place your URL in this file, now run the playbook and your agents should come online

ansible-playbook rancherAgent.yml

stick a line in cron that runs it every five minutes and you’ll ensure their up and running
