# 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.
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
* 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 minions. (master can be a minion)
|
|
|
|
|
|
|
|
Stick the system information 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:
|
|
|
|
|
|
|
|
$ ansible-playbook -i inventory cluster.yml
|
|
|
|
|
|
|
|
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
|
2015-04-03 16:37:57 +00:00
|
|
|
|
|
|
|
Only flannel:
|
|
|
|
|
|
|
|
$ ansible-playbook -i inventory flannel.yml
|
