Deploy Openshift v3.1 on OpenStack

The purpose of this project is to minimize as much manual setup as possible

A complete howto for a manual setup of openshift on openstack can be found here https://blog.openshift.com/setting-openshift-3-openstack/ by Veer Muchandi

Steps

• We make use of the nova client for access to openstack

• If not installed please install it

• A comprehensive guide can be found here http://docs.openstack.org/user-guide/common/cli_install_openstack_command_line_clients.html

• A quick guide to install novaclient on your local machine (assuming you have python installed)

  • pip install python-novaclient
  • pip install python-barbicanclient
  • pip install python-ceilometerclient
  • pip install python-cinderclient
  • pip install python-glanceclient
  • pip install python-gnocchiclient
  • pip install python-heatclient
  • pip install python-magnumclient
  • pip install python-manilaclient
  • pip install python-mistralclient
  • pip install python-muranoclient
  • pip install python-neutronclient
  • pip install python-novaclient
  • pip install python-saharaclient
  • pip install python-swiftclient
  • pip install python-troveclient
  • pip install python-tuskarclient
  • pip install python-openstackclient

• Ensure you have access to openstack and the RHMAP tenant (if not create a service request to allow you access to public openstack RHMAP tenant)

• Login and go to the Access&Security tab then navigate to the API Access sub tab

• Click on the 'Download OpenStack RC File'

• This file will be used in the nova-create.sh script

• The nova-create script will do the following :-

  • Initialise the nova client access (it will ask you for a password)
  • Create a key-pair pem file for access into each instance that is created
  • Create a security group
  • Add rules to this group
  • Launch 4 instances using m1.large flavor and Rhel7.1 guest image (master and 3 nodes)
  • The command nova-list can be used to obtain ip addresses which should be used to update the host file
  • TBD - create floating ip
  • TBD - associate floating ip to instance
  • TBD - create volume (size 15G)
  • TBD - associate volume to instance (use /dev/vdb as device)
  • TBD - check subscription manager (might have to add nameserver 8.8.8.8 nameserver 8.8.4.4 to /etc/resolv.conf)
  • TBD - docker setup (cat < /etc/sysconfig/docker-storage-setup DEVS=/dev/vdb VG=docker-vg EOF
  • TBD - execute docker-storage-setup and verify cat /etc/sysconfig/docker-storage
  • TBD - systemctl restart docker
  • TBD - sudo lvextend -r -l +100%FREE /dev/docker-vg/docker-pool

• Once this is completed the xpaas script will execute doing :-

  • Subscription registration

  • Update repositories

  • Install the relevant software

  • Update hostnames

  • Remove NetworkManagr

  • Install and start docker

  • Generate ssh keys

  • Install ansible

  • Clone the openshift ansible git repo

  • Install openshift

  • Configure openshift

  • TBD - sudo su yum -y install httpd-tools touch /etc/origin/htpasswd htpasswd -c /etc/origin/htpasswd test # enter test as the password
