Deploy Kubernetes Using OpenStack Ironic

Setup a containerize Ironic environment, and deploy Kubernetes using Ironic.

Requirements:

• GNU make
• Docker

Install Docker engine:

$ curl -fsSL "https://get.docker.com/" | sh

Usage

In order to create the ironic service on Ubuntu16 or Centos7 as follows step.

Deploy Ironic service

Download this repository via git:

$ git clone https://github.com/kairen/ironic-k8s-dev.git
$ cd ironic-k8s-dev/docker

Build standalone ironic containers:

$ make build

Edit config.env file:

# Host ip address
HOST_IP=172.22.132.93

# RabbitMQ credentials
RABBITMQ_DEFAULT_USER=guest
RABBITMQ_DEFAULT_PASS=rabbit_secret

# MariaDB credentials
MYSQL_ROOT_PASSWORD=sql_secret
MYSQL_IRONIC_PASSWORD=ironic_secret

# dnsmasq settings
IPMI_INTERFACE=enp6s0
DATA_INTERFACE=enp7s0
IPMI_RANGE=172.20.3.10,172.20.3.100,12h
DATA_RANGE=172.22.132.10,172.22.132.100,12h
BOOT_IPXE_ENDPOINT="http://${HOST_IP}:8080/boot.ipxe"

# Ironic Settings
IRONIC_DEBUG=false

To run the ironic service:

$ make deploy

(option)To reset the ironic service:

$ make reset

Create boot image

To build the OS images:

$ ssh-keygen -t rsa
$ cd ironic-k8s-dev/docker
$ make dib
root@daq31-ca314# create-k8s-image

Add a baremetal node

To boot a node use:

$  virtualenv .ironic
$ source .ironic/bin/activate
(.ironic)$ pip install -U pip
(.ironic)$ pip install python-ironicclient

# (.ironic)
$ ironic node-create -d agent_ipmitool \
                     -n ironic-bare \
                     -i ipmi_address=172.20.3.194 \
                     -i ipmi_username=maas \
                     -i ipmi_password=NCCflzyX349iJ

$ ironic node-update ironic-bare add driver_info/deploy_ramdisk=http://172.22.132.93:8080/ipa.initramfs \
                               driver_info/deploy_kernel=http://172.22.132.93:8080/ipa.vmlinuz \

                               properties/cpu_arch=x86_64 \

                               instance_info/kernel=http://172.22.132.93:8080/k8s.vmlinuz \

                               instance_info/root_gb=100

$ ironic port-create -n <NODE_UUID> -a <NODE_ETH_MAC>
$ ironic node-validate ironic-bare
$ ironic node-set-provision-state ironic-bare active

To test the IPMI of node:

$ ipmitool -U <USER> -P <PASSWD> -H <HOST_IP> chassis power status
