|
||||
This page details how to deploy and use an Overcloud once the Undercloud is
|
||||
installed.
|
||||
|
||||
Deploying
|
||||
---------
|
||||
There are 3 scripts for convenience.
|
||||
|
||||
1. In case you're still using the same shell, the install script has to manipulate your $PATH (until we get everything
|
||||
packaged), so you'll need to start a new shell environment.
|
||||
Note that deploy-overcloud can be configured for individual environments via
|
||||
environment variables. The variables you can set are documented below before
|
||||
the calls to the script. For their default values, see the deploy-overcloud
|
||||
script itself.
|
||||
|
||||
bash
|
||||
1. Run the prepare-for-overcloud script to get setup. This script will
|
||||
re-downloading images if they already exist in the current working directory.
|
||||
If you want to force a redownload of the images, delete them first.
|
||||
|
||||
4. Copy the stackrc file to your homedir so that you can use it a normal user.
|
||||
prepare-for-overcloud
|
||||
|
||||
source /etc/sysconfig/stackrc
|
||||
1. If you're testing an all VM setup, copy the ssh key for the virtual power
|
||||
driver user to your authorized keys file. Define $UNDERCLOUD_IP for your
|
||||
environment. Skip this step if you are using all baremetal.
|
||||
|
||||
4. Add your ssh key pair to nova
|
||||
ssh $UNDERCLOUD_IP cat /opt/stack/boot-stack/virtual-power-key.pub >> ~/.ssh/authorized_keys
|
||||
|
||||
1. Run the deploy-overcloud script to actually deploy the overcloud
|
||||
|
||||
user-config
|
||||
# CPU: number of cpus on baremetal nodes
|
||||
# MEM: amount of ram on baremetal nodes, in MB
|
||||
# DISK: amount of disk on baremetal nodes, in GB
|
||||
# ARCH: architecture of baremetal nodes, amd64 or i386
|
||||
# MACS: list of MAC addresses of baremetal nodes
|
||||
# PM_IPS: list of Power Management IP addresses
|
||||
# PM_USERS: list of Power Management Users
|
||||
# PM_PASSWORDS: list of Power Management Passwords
|
||||
# NeutronPublicInterface: Overcloud management interface name
|
||||
# OVERCLOUD_LIBVIRT_TYPE: Overcloud libvirt type, qemu or kvm
|
||||
deploy-overcloud
|
||||
|
||||
5. Download the deployment kernel and ramdisk
|
||||
1. Run the test-overcloud script to launch a cirros image on the overcloud and
|
||||
wait until it pings successfully
|
||||
|
||||
curl -L -O http://file.rdu.redhat.com/~jslagle/tripleo-images-rdo-icehouse/deploy-ramdisk.initramfs
|
||||
curl -L -O http://file.rdu.redhat.com/~jslagle/tripleo-images-rdo-icehouse/deploy-ramdisk.kernel
|
||||
|
||||
5. Download overcloud images
|
||||
|
||||
curl -L -O http://file.rdu.redhat.com/~jslagle/tripleo-images-rdo-icehouse/overcloud-control.qcow2
|
||||
curl -L -O http://file.rdu.redhat.com/~jslagle/tripleo-images-rdo-icehouse/overcloud-compute.qcow2
|
||||
|
||||
5. Load images into glance
|
||||
|
||||
load-image overcloud-control.qcow2
|
||||
load-image overcloud-compute.qcow2
|
||||
|
||||
6. Use the setup-baremetal script to add your baremetal nodes
|
||||
|
||||
# setup-baremetal requires this to be set
|
||||
export TRIPLEO_ROOT=.
|
||||
# $CPU = cpu count per node
|
||||
# $MEM = memory per node in MB
|
||||
# $DISK = disk per node in GB
|
||||
# $ARCH = architecture of each node, i386 or amd64
|
||||
# $MACS = space separated list of node mac addresses
|
||||
# $PM_IPS = space separated list of power management IP addresses
|
||||
# $PM_USERS = space separated list of power management users
|
||||
# $PM_PASSWORDS = space separated list of power management passwords
|
||||
# $MACS and $PM_* variables should be in the same node order, e.g., the
|
||||
# first MAC address should correspond to the first power management
|
||||
# IP, etc.
|
||||
setup-baremetal $CPU $MEM $DISK $ARCH "$MACS" undercloud "$PM_IPS" "$PM_USERS" "$PM_PASSWORDS"
|
||||
|
||||
7. Create your overcloud heat template. You can adjust COMPUTESCALE to launch
|
||||
more than one compute node if you choose to.
|
||||
|
||||
tripleo-heat-merge \
|
||||
--included-template-dir /usr/share/tripleo-heat-templates \
|
||||
--scale NovaCompute=1 \
|
||||
/usr/share/tripleo-heat-templates/overcloud-source.yaml \
|
||||
/usr/share/tripleo-heat-templates/swift-source.yaml \
|
||||
/usr/share/tripleo-heat-templates/ssl-source.yaml \
|
||||
> overcloud.yaml
|
||||
|
||||
|
||||
8. Create and source the overcloud passwords
|
||||
|
||||
setup-overcloud-passwords
|
||||
source tripleo-overcloud-passwords
|
||||
|
||||
9. Deploy the overcloud
|
||||
|
||||
# Define the interface that will be bridged onto the Neutron defined
|
||||
# network.
|
||||
NeutronPublicInterface=eth0
|
||||
# Define the overcloud libvirt type for virtualization. kvm for
|
||||
# baremetal, qemu for an overcloud running in vm's.
|
||||
OVERCLOUD_LIBVIRT_TYPE=kvm
|
||||
|
||||
heat stack-create -f overcloud.yaml \
|
||||
-P AdminToken=${OVERCLOUD_ADMIN_TOKEN} \
|
||||
-P AdminPassword=${OVERCLOUD_ADMIN_PASSWORD} \
|
||||
-P CinderPassword=${OVERCLOUD_CINDER_PASSWORD} \
|
||||
-P GlancePassword=${OVERCLOUD_GLANCE_PASSWORD} \
|
||||
-P HeatPassword=${OVERCLOUD_HEAT_PASSWORD} \
|
||||
-P NeutronPassword=${OVERCLOUD_NEUTRON_PASSWORD} \
|
||||
-P NovaPassword=${OVERCLOUD_NOVA_PASSWORD} \
|
||||
-P NeutronPublicInterface=$NeutronPublicInterface \
|
||||
-P SwiftPassword=${OVERCLOUD_SWIFT_PASSWORD} \
|
||||
-P SwiftHashSuffix=${OVERCLOUD_SWIFT_HASH} \
|
||||
-P NovaComputeLibvirtType=$OVERCLOUD_LIBVIRT_TYPE \
|
||||
overcloud
|
||||
|
||||
Using the Overcloud
|
||||
-------------------
|
||||
The scripted steps for configuring and using the Overcloud by launching a
|
||||
single cirros instance in it are scripted at scripts/overcloud.
|
||||
|
||||
|
||||
You can also use the devtest instructions to walk through it manually. Start off with step 11 from
|
||||
http://docs.openstack.org/developer/tripleo-incubator/devtest_overcloud.html.
|
||||
|
||||
You won't be able to follow the steps exactly. Here's what you need to modify:
|
||||
|
||||
* When source'ing the rc files use the following paths instead of what's shown:
|
||||
|
||||
source /etc/tripleo/overcloudrc
|
||||
source /etc/tripleo/overcloudrc-user
|
||||
|
||||
* When running setup-neutron, correct subnet ranges will need to be used if
|
||||
192.0.2.0/24 is not applicable to the environment.
|
||||
* When loading the user.qcow2 image into glance, I would use a cirros image
|
||||
instead. Download the cirros image from
|
||||
https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img
|
||||
and specify the path to the downloaded file when you run the glance command.
