Application Deployment + +Your journey begins with deploying your application on Kubernetes. This typically involves: + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: my-app + namespace: my-namespace +spec: + replicas: 1 + selector: + matchLabels: + app: my-app + template: + metadata: + labels: + app: my-app + spec: + containers: + - name: my-app + image: myapp:latest + ports: + - containerPort: 80 +``` + +This creates pods running your application, but they're not yet accessible outside their namespace. + +### 2. Kubernetes Service: Internal Connectivity + +A Kubernetes Service provides a stable endpoint to access your pods: + +```yaml +apiVersion: v1 +kind: Service +metadata: + name: my-app + namespace: my-namespace +spec: + selector: + app: my-app + ports: + - port: 80 + targetPort: 80 + type: ClusterIP +``` + +With this `ClusterIP` service, your application is accessible within the cluster at `my-app.my-namespace.svc.cluster.local`, but not from outside. + +### 3. Ingress: Defining HTTP Routes + +For HTTP/HTTPS traffic, an Ingress resource defines routing rules: + +```yaml +apiVersion: networking.k8s.io/v1 +kind: Ingress +metadata: + name: my-app + namespace: my-namespace + annotations: + kubernetes.io/ingress.class: "traefik" + external-dns.alpha.kubernetes.io/target: "CLOUD_DOMAIN" + external-dns.alpha.kubernetes.io/ttl: "60" +spec: + rules: + - host: my-app.CLOUD_DOMAIN + http: + paths: + - path: / + pathType: Prefix + backend: + service: + name: my-app + port: + number: 80 + tls: + - hosts: + - my-app.CLOUD_DOMAIN + secretName: wildcard-sovereign-cloud-tls +``` + +This Ingress tells the cluster to route requests for `my-app.CLOUD_DOMAIN` to your service. The annotations provide hints to other systems like ExternalDNS. + +### 4. Traefik: The Ingress Controller + +Our cluster uses Traefik as the ingress controller. Traefik watches for Ingress resources and configures itself to handle the routing rules. It acts as a reverse proxy and edge router, handling: + +- HTTP/HTTPS routing +- TLS termination +- Load balancing +- Path-based routing +- Host-based routing + +Traefik runs as a service in the cluster with its own external IP (provided by MetalLB). + +### 5. MetalLB: Assigning External IPs + +Since we're running on-premises (not in a cloud that provides load balancers), we use MetalLB to assign external IPs to services. MetalLB manages a pool of IP addresses from our local network: + +```yaml +apiVersion: metallb.io/v1beta1 +kind: IPAddressPool +metadata: + name: default + namespace: metallb-system +spec: + addresses: + - 192.168.8.240-192.168.8.250 +``` + +This allows Traefik and any other LoadBalancer services to receive a real IP address from our network. + +### 6. ExternalDNS: Automated DNS Management + +ExternalDNS automatically creates and updates DNS records in our CloudFlare DNS zone: + +```yaml +apiVersion: apps/v1 +kind: Deployment +metadata: + name: external-dns + namespace: externaldns +spec: + # ... + template: + spec: + containers: + - name: external-dns + image: registry.k8s.io/external-dns/external-dns + args: + - --source=service + - --source=ingress + - --provider=cloudflare + - --txt-owner-id=sovereign-cloud +``` + +ExternalDNS watches Kubernetes Services and Ingresses with appropriate annotations, then creates corresponding DNS records in CloudFlare, making your applications discoverable by domain name. + +### 7.
