The quickstart guide is for new developers to quickly setup the environment and they are unlike to setup additional nodes as part of the quick start. So let's split the multi-node setup session out. Change-Id: I83f7aa61ec0c2681a5b9e79950ebde27879ca961

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
