@ -4,13 +4,15 @@ This playbook helps you to set up a Kubernetes cluster on machines where you
can't or don't want to use the salt scripts and cluster up/down tools. They
can be real hardware, VMs, things in a public cloud, etc.
## Usage
## Before starting
* Record the IP address of which machine you want to be your master
* Record the IP address of the machine you want to be your etcd server (often same as master)
* Record the IP addresses of the machines you want to be your nodes. (master can be a node)
* Record the IP address/hostname of which machine you want to be your master (only support a single master)
* Record the IP address/hostname of the machine you want to be your etcd server (often same as master, only one)
* Record the IP addresses/hostname of the machines you want to be your nodes. (the master can also be a node)

Now run the setup:
$ ansible-playbook -i inventory cluster.yml
`$ ./setup.sh`
In generel this will work on very recent Fedora, rawhide or F21. Future work to
support RHEL7, CentOS, and possible other distros should be forthcoming.
### You can just set up certain parts instead of doing it all
Only the kubernetes daemons:
$ ansible-playbook -i inventory kubernetes-services.yml
Only etcd:
$ ansible-playbook -i inventory etcd.yml
`$ ./setup.sh --tags=etcd`
Only flannel:
Only the kubernetes master:
$ ansible-playbook -i inventory flannel.yml
`$ ./setup.sh --tags=masters`
Only the kubernetes nodes:
`$ ./setup.sh --tags=nodes`
### You may overwrite the inventory file by doing
`INVENTORY=myinventory ./setup.sh`
