OPENSTACK Setup instructions

Requirements

The OpenStack instance must have Neutron and Heat enabled.

On RHEL / CentOS / Fedora:

  yum install -y ansible python-novaclient python-neutronclient python-heatclient

The following options can be passed via the -o flag of the create command:

infra_heat_stack (default to playbooks/openstack/openshift-cluster/files/heat_stack.yaml): filename of the HEAT template to use to create the cluster infrastructure

The following options are used only by heat_stack.yaml. They are so used only if the infra_heat_stack option is left with its default value.

image_name: Name of the image to use to spawn VMs
public_key (default to ~/.ssh/id_rsa.pub): filename of the ssh public key
master_flavor (default to m1.small): The ID or name of the flavor for the master
node_flavor (default to m1.medium): The ID or name of the flavor for the compute nodes
infra_flavor (default to m1.small): The ID or name of the flavor for the infrastructure nodes
network_prefix (default to openshift-ansible-<cluster_id>): prefix prepended to all network objects (net, subnet, router, security groups)
dns (default to 8.8.8.8,8.8.4.4): comma separated list of DNS to use
net_cidr (default to 192.168.<rand()>.0/24): CIDR of the network created by heat_stack.yaml
external_net (default to external): Name of the external network to connect to
floating_ip_pool (default to external): comma separated list of floating IP pools
ssh_from (default to 0.0.0.0/0): IPs authorized to connect to the VMs via ssh

  bin/cluster create openstack <cluster-id>

To create a cluster with one master and three nodes, a custom VM image and custom DNS:

  bin/cluster create -n 3 -o image_name=rhel-7.1-openshift-2015.05.21 -o dns=172.16.50.210,172.16.50.250 openstack lenaic

  bin/cluster update openstack <cluster-id>

  bin/cluster terminate openstack <cluster-id>
