I’m new to Ansible, and trying to write a state to set up and bootstrap a Consul cluster. I seem to have the basics down (downloading packages, and all.) However, I’m stuck on the components of the bootstrap process ([http://www.consul.io/docs/guides/bootstrapping.html](http://www.consul.io/docs/guides/bootstrapping.html)). Specifically: - How can I ensure that a given set of tasks only executes if a command succeeds/fails on _all_ the target servers? - How can I run a command on only one server, followed by all the rest? Starting servers in consul is pretty easy. But the bootstrap process is a delicate little dance right now, one which I feel Ansible could deal with pretty well. But without these two things, is there any way it could be done? ---

Basically installing any arbitrary application with Ansible (how to write a playbook) is a bit out of scope for this list. I’d take a look at [github.com/ansible/ansible-examples](http://github.com/ansible/ansible-examples) and more importantly [galaxy.ansible.com](http://galaxy.ansible.com) for some starters on playbook construction, review module docs, and go from there. If Consul is hard to install, that is somewhat of Consul’s problem, alas 🙂
