The xci/installer/kubespray/files/k8s-cluster.yml is obtained from kubespray. You can change the parameters according to your needs. When starting the deploy, it will be copied to the right directory and will be used by kubespray For example: kube_network_plugin: calico docker_storage_options: -s overlay2 kube_service_addresses: 10.233.0.0/18 Requirements: 1. Performance of hosts The performance settings are not required officially. I recommend the following: - VM_CPU=6 - VM_DISK=80GB - VM_MEMORY_SIZE=16GB 2. Distributions - Ubuntu 16.04 3. Packages: - Ansible v2.4 (or newer) and python-netaddr is installed on the machine that will run Ansible commands - Jinja 2.9 (or newer) is required to run the Ansible Playbooks 4. Others: - The target servers must have access to the Internet in order to pull docker images. - The target servers are configured to allow IPv4 forwarding. - Your ssh key must be copied to all the servers part of your inventory. - The firewalls are not managed, you'll need to implement your own rules the way you used to. In order to avoid any issue during the deployment you should disable your firewall. Flavors: 1. aio: Single host which acts as the deployment host, master and node. 2. mini: One deployment host, 1 master host and 1 node host. 3. noha: One deployment host, 1 master host and 2 node hosts. 4. ha: One deployment host, 3 master hosts and 2 node hosts. Components Installed: 1. etcd 2. network plugins:(one of following, which you can choose. Default is calico) - calico - flannel - contive - weave 3. kubernetes 4. docker How to use: Clone the OPNFV Releng repository git clone https://gerrit.opnfv.org/gerrit/releng-xci.git Change into the directory where the sandbox script is located cd releng-xci/xci Set the variable to run kubespray export XCI_INSTALLER=kubespray export DEPLOY_SCENARIO=k8-nosdn-nofeature export XCI_FLAVOR=mini Execute sandbox script ./xci-deploy.sh
