Multi-host Devstack
|
|
===================
|
|
|
|
This is a guide for developers who want to setup Zun in more than one hosts.
|
|
|
|
Prerequisite
|
|
============
|
|
|
|
You need to deploy Zun in a devstack environment in the first host.
|
|
|
|
Refer the ``Exercising the Services Using Devstack`` session at `Developer
|
|
Quick-Start Guide <https://docs.openstack.org/zun/latest/contributor/quickstart.html#exercising-the-services-using-devstack>`_
|
|
for details.
|
|
|
|
Enable additional zun host
|
|
==========================
|
|
|
|
Refer to the `Multi-Node lab
|
|
<https://docs.openstack.org/devstack/latest/guides/multinode-lab.html>`__
|
|
for more information.
|
|
|
|
On the second host, clone devstack::
|
|
|
|
# Create a root directory for devstack if needed
|
|
$ sudo mkdir -p /opt/stack
|
|
$ sudo chown $USER /opt/stack
|
|
|
|
$ git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
|
|
|
|
The second host will only need zun-compute service along with kuryr-libnetwork
|
|
support. You also need to tell devstack where the SERVICE_HOST is::
|
|
|
|
$ SERVICE_HOST=<controller's ip>
|
|
$ HOST_IP=<your ip>
|
|
$ git clone https://git.openstack.org/openstack/zun /opt/stack/zun
|
|
$ cat /opt/stack/zun/devstack/local.conf.subnode.sample \
|
|
| sed "s/HOST_IP=.*/HOST_IP=$HOST_IP/" \
|
|
| sed "s/SERVICE_HOST=.*/SERVICE_HOST=$SERVICE_HOST/" \
|
|
> /opt/stack/devstack/local.conf
|
|
|
|
Run devstack::
|
|
|
|
$ cd /opt/stack/devstack
|
|
$ ./stack.sh
|
|
|
|
On the controller host, you can see 2 zun-compute hosts available::
|
|
|
|
$ zun service-list
