To deploy Kubernetes on CloudStack there are several possibilities depending on the Cloud being used and what images are made available. [Exoscale](http://exoscale.ch) for instance makes a [CoreOS](http://coreos.com) template available, therefore instructions to deploy Kubernetes on coreOS can be used. CloudStack also has a vagrant plugin available, hence Vagrant could be used to deploy Kubernetes either using the existing shell provisioner or using new Salt based recipes. 46 47 [CoreOS](http://coreos.com) templates for CloudStack are built [nightly](http://stable.release.core-os.net/amd64-usr/current/). CloudStack operators need to [register](http://docs.cloudstack.apache.org/projects/cloudstack-administration/en/latest/templates.html) this template in their cloud before proceeding with these Kubernetes deployment instructions. 48 49 This guide uses an [Ansible playbook](https://github.com/runseb/ansible-kubernetes). 50 This is a completely automated, a single playbook deploys Kubernetes based on the coreOS [instructions](coreos/coreos_multinode_cluster.md). 51 52 53 This [Ansible](http://ansibleworks.com) playbook deploys Kubernetes on a CloudStack based Cloud using CoreOS images. The playbook, creates an ssh key pair, creates a security group and associated rules and finally starts coreOS instances configured via cloud-init. 54 55 ### Prerequisites 56 57 $ sudo apt-get install -y python-pip 58 $ sudo pip install ansible 59 $ sudo pip install cs 60 61 [_cs_](https://github.com/exoscale/cs) is a python module for the CloudStack API. 62 63 Set your CloudStack endpoint, API keys and HTTP method used. 64 65 You can define them as environment variables: `CLOUDSTACK_ENDPOINT`, `CLOUDSTACK_KEY`, `CLOUDSTACK_SECRET` and `CLOUDSTACK_METHOD`. 66 67 Or create a `~/.cloudstack.ini` file: 68 69 [cloudstack] 70 endpoint = <your cloudstack api endpoint> 71 key = <your api access key> 72 secret = <your api secret key> 73 method = post 74 75 We need to use the http POST method to pass the _large_ userdata to the coreOS instances. 76 77 ### Clone the playbook 78 79 $ git clone --recursive https://github.com/runseb/ansible-kubernetes.git 80 $ cd ansible-kubernetes 81 82 The [ansible-cloudstack](https://github.com/resmo/ansible-cloudstack) module is setup in this repository as a submodule, hence the `--recursive`. 83 84 ### Create a Kubernetes cluster 85 86 You simply need to run the playbook. 87 88 $ ansible-playbook k8s.yml 89 90 Some variables can be edited in the `k8s.yml` file. 91 92 vars: 93 ssh_key: k8s 94 k8s_num_nodes: 2 95 k8s_security_group_name: k8s 96 k8s_node_prefix: k8s2 97 k8s_template: Linux CoreOS alpha 435 64-bit 10GB Disk 98 k8s_instance_type: Tiny 99 100 This will start a Kubernetes master node and a number of compute nodes (by default 2). 101 The `instance_type` and `template` by default are specific to [exoscale](http://exoscale.ch), edit them to specify your CloudStack cloud specific template and instance type (i.e service offering). 102 103 Check the tasks and templates in `roles/k8s` if you want to modify anything. 104 105 Once the playbook as finished, it will print out the IP of the Kubernetes master: 106 107 TASK: [k8s | debug msg='k8s master IP is {{ k8s_master.default_ip }}'] ******** 108 109 SSH to it using the key that was created and using the _core_ user and you can list the machines in your cluster: 110 111 $ ssh -i ~/.ssh/id_rsa_k8s core@<master IP> 112 $ fleetctl list-machines 113 MACHINE IP METADATA 114 a017c422... <node #1 IP> role=node 115 ad13bf84... <master IP> role=master 116 e9af8293... <node #2 IP> role=node 117 118 119 <!-- BEGIN MUNGE: GENERATED_ANALYTICS --> 120 [![Analytics](https://kubernetes-site.appspot.com/UA-36037335-10/GitHub/docs/getting-started-guides/cloudstack.md?pixel)]() 121 <!-- END MUNGE: GENERATED_ANALYTICS -->
