# Kubernetes Ansible
|
|
|
|
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.
|
|
|
|
## Before starting
|
|
|
|
* 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)
|
|
|
|
### Configure the inventory file
|
|
|
|
Stick the system information gathered above into the 'inventory' file.
|
|
|
|
### Configure your cluster
|
|
|
|
You will want to look though all of the options in `group_vars/all.yml` and
|
|
set the variables to reflect your needs. The options should be described there
|
|
in full detail.
|
|
|
|
### Set up the actual kubernetes cluster
|
|
|
|
Now run the setup:
|
|
|
|
`$ ./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 etcd:
|
|
|
|
`$ ./setup.sh --tags=etcd`
|
|
|
|
Only the kubernetes master:
|
|
|
|
`$ ./setup.sh --tags=masters`
|
|
|
|
Only the kubernetes nodes:
|
|
|
|
`$ ./setup.sh --tags=nodes`
|
|
|
|
### You may overwrite the inventory file by doing
|
|
|
|
`INVENTORY=myinventory ./setup.sh`
|
|
|
|
Only flannel:
|
|
|
|
$ ./setup.sh --tags=flannel
|
|
