Deploy Placement

cd /opt/genestack/submodules/openstack-helm

helm upgrade --install placement ./placement --namespace=openstack \
  --namespace=openstack \
    --timeout 120m \
    -f /opt/genestack/base-helm-configs/placement/placement-helm-overrides.yaml \
    --set endpoints.identity.auth.admin.password="$(kubectl --namespace openstack get secret keystone-admin -o jsonpath='{.data.password}' | base64 -d)" \
    --set endpoints.identity.auth.placement.password="$(kubectl --namespace openstack get secret placement-admin -o jsonpath='{.data.password}' | base64 -d)" \
    --set endpoints.oslo_db.auth.admin.password="$(kubectl --namespace openstack get secret mariadb -o jsonpath='{.data.root-password}' | base64 -d)" \
    --set endpoints.oslo_db.auth.placement.password="$(kubectl --namespace openstack get secret placement-db-password -o jsonpath='{.data.password}' | base64 -d)" \
    --set conf.placement.placement_database.slave_connection="mysql+pymysql://placement:$(kubectl --namespace openstack get secret placement-db-password -o jsonpath='{.data.password}' | base64 -d)@mariadb-cluster-secondary.openstack.svc.cluster.local:3306/placement" \
    --set endpoints.oslo_db.auth.nova_api.password="$(kubectl --namespace openstack get secret nova-db-password -o jsonpath='{.data.password}' | base64 -d)" \
    --post-renderer /opt/genestack/base-kustomize/kustomize.sh \
    --post-renderer-args placement/base

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": "placement-https",
            "port": 443,
            "protocol": "HTTPS",
            "hostname": "placement.your.domain.tld",
            "allowedRoutes": {
                "namespaces": {
                    "from": "All"
                }
            },
            "tls": {
                "certificateRefs": [
                    {
                        "group": "",
                        "kind": "Secret",
                        "name": "placement-gw-tls-secret"
                    }
                ],
                "mode": "Terminate"
            }
        }
    }
]

Modify the Listener Patch

This example changes the placeholder domain to <YOUR_DOMAIN>. Review the gateway documentation for more information on listener types.

mkdir -p /etc/genestack/gateway-api/listeners
sed 's/your.domain.tld/<YOUR_DOMAIN>/g' \
    /opt/genestack/etc/gateway-api/listeners/placement-https.json \
    > /etc/genestack/gateway-api/listeners/placement-https.json

Apply the Listener Patch

kubectl patch -n nginx-gateway gateway flex-gateway \
              --type='json' \
              --patch-file /etc/genestack/gateway-api/listeners/placement-https.json

Custom Placement 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-placement-gateway-route
  namespace: openstack
  labels:
    application: gateway-api
    service: HTTPRoute
    route: placement
spec:
  parentRefs:
  - name: flex-gateway
    sectionName: placement-https
    namespace: nginx-gateway
  hostnames:
  - "placement.your.domain.tld"
  rules:
    - backendRefs:
      - name: placement-api
        port: 8778

Modify the Placement 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-placement-gateway-route.yaml \
    > /etc/genestack/gateway-api/routes/custom-placement-gateway-route.yaml

Apply the Placement Route

kubectl --namespace openstack apply -f /etc/genestack/gateway-api/routes/custom-placement-gateway-route.yaml
