Enable the second zun host
==========================
Refer to the `Multi-Node lab
<https://docs.openstack.org/developer/devstack/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::
$ export CTRL_IP=<controller's ip>
$ cat > /opt/stack/devstack/local.conf << END
[[local|localrc]]
HOST_IP=$(ip addr | grep 'state UP' -A2 | tail -n1 | awk '{print $2}' | cut -f1 -d'/')
DATABASE_PASSWORD=password
RABBIT_PASSWORD=password
SERVICE_TOKEN=password
SERVICE_PASSWORD=password
ADMIN_PASSWORD=password
enable_plugin zun https://git.openstack.org/openstack/zun
enable_plugin kuryr-libnetwork https://git.openstack.org/openstack/kuryr-libnetwork
# Following is for multi host settings
MULTI_HOST=True
SERVICE_HOST=$CTRL_IP
DATABASE_TYPE=mysql
MYSQL_HOST=$CTRL_IP
RABBIT_HOST=$CTRL_IP
ENABLED_SERVICES=zun-compute,kuryr-libnetwork,q-agt
END
Run devstack::
cd /opt/stack/devstack
./stack.sh
On the controller host, you can see 2 zun-compute hosts available::
