Tip
You may need to provide custom values to configure your openstack services, for a simple single region or lab deployment you can supply an additional overrides flag using the example found at base-helm-configs/aio-example-openstack-overrides.yaml
.
In other cases such as a multi-region deployment you may want to view the Multi-Region Support guide to for a workflow solution.
Info
The above command derives the OVN north/south bound database from our K8S environment. The insert set
is making the assumption we're using tcp to connect.
Custom Listeners
This step is not needed if all listeners were applied when the Gateway API was deployed
Example listener patch file found in /opt/genestack/etc/gateway-api/listeners
[
{
"op": "add",
"path": "/spec/listeners/-",
"value": {
"name": "neutron-https",
"port": 443,
"protocol": "HTTPS",
"hostname": "neutron.your.domain.tld",
"allowedRoutes": {
"namespaces": {
"from": "All"
}
},
"tls": {
"certificateRefs": [
{
"group": "",
"kind": "Secret",
"name": "neutron-gw-tls-secret"
}
],
"mode": "Terminate"
}
}
}
]
This example changes the placeholder domain to <YOUR_DOMAIN>
. Review the gateway documentation
for more information on listener types.
Modify the Listener Patch
mkdir -p /etc/genestack/gateway-api/listeners
sed 's/your.domain.tld/<YOUR_DOMAIN>/g' \
/opt/genestack/etc/gateway-api/listeners/neutron-https.json \
> /etc/genestack/gateway-api/listeners/neutron-https.json
Apply the Listener Patch
kubectl patch -n nginx-gateway gateway flex-gateway \
--type='json' \
--patch-file /etc/genestack/gateway-api/listeners/neutron-https.json
Custom Neutron Routes
This step is not needed if all routes were applied when the Gateway API was deployed
A custom gateway route can be used when setting up the service. The custom route make it possible to for a domain like your.domain.tld
to be used for the service.
Example routes file found in /opt/genestack/etc/gateway-api/routes
---
apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
name: custom-neutron-gateway-route
namespace: openstack
labels:
application: gateway-api
service: HTTPRoute
route: neutron
spec:
parentRefs:
- name: flex-gateway
sectionName: neutron-https
namespace: nginx-gateway
hostnames:
- "neutron.your.domain.tld"
rules:
- backendRefs:
- name: neutron-server
port: 9696
Modify the Neutron Route
This example changes the placeholder domain to <YOUR_DOMAIN>
. Review the gateway route documentation
for more information on route types.
mkdir -p /etc/genestack/gateway-api/routes
sed 's/your.domain.tld/<YOUR_DOMAIN>/g' \
/opt/genestack/etc/gateway-api/routes/custom-neutron-gateway-route.yaml \
