配置ingress访问。

Prometheus ingress-NGINX配置文件

cat alertmanager-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: prometheus-ingress
  namespace: kube-system
  annotations:
    nginx.ingress.kubernetes.io/affinity: cookie
    nginx.ingress.kubernetes.io/session-cookie-name: "prometheus-cookie"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: "letsencrypt-local"
    kubernetes.io/tls-acme: "false"
spec:
  rules:
  - host: prom.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: prometheus
          servicePort: 9090
  tls:
  - hosts:
      - prom.example.com

Alertmanager ingress-NGINX配置文件

cat alertmanager-ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: alertmanager-ingress
  namespace: kube-system
  annotations:
    nginx.ingress.kubernetes.io/affinity: cookie
    nginx.ingress.kubernetes.io/session-cookie-name: "alert-cookie"
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
    kubernetes.io/ingress.class: nginx
    certmanager.k8s.io/cluster-issuer: "letsencrypt-local"
    kubernetes.io/tls-acme: "false"
spec:
  rules:
  - host: alert.example.com
    http:
      paths:
      - path: /
        backend:
          serviceName: alertmanager-operated
          servicePort: 9093
  tls:
  - hosts:
      - alert.example.com

Grafana ingress-NGINX配置文件

部署

cat grafana-ingress.yaml apiVersion: extensions/v1beta1 kind: Ingress metadata: name: grafana-ingress namespace: kube-system annotations: nginx.ingress.kubernetes.io/affinity: cookie nginx.ingress.kubernetes.io/session-cookie-name: "grafana-cookie" nginx.ingress.kubernetes.io/ssl-redirect: "false" kubernetes.io/ingress.class: nginx certmanager.k8s.io/cluster-issuer: "letsencrypt-local" kubernetes.io/tls-acme: "false" spec: rules: - host: grafana.example.com http: paths: - path: / backend: serviceName: grafana servicePort: http tls: - hosts: - grafana.example.com

cd /data/manual-deploy/ingress-nginx
alertmanager-ingress.yaml
grafana-ingress.yaml
prometheus-ingress.yaml
kubectl apply -f alertmanager-ingress.yaml
kubectl apply -f prometheus-ingress.yaml
kubectl apply -f grafana-ingress.yaml

验证

kubectl -n kube-system get ingresses
NAME                   HOSTS                 ADDRESS         PORTS     AGE
alertmanager-ingress   alert.example.com     10.110.106.22   80, 443   15h
grafana-ingress        grafana.example.com   10.110.106.22   80, 443   30h
prometheus-ingress     prom.example.com      10.110.106.22   80, 443   15h

然后可以在在本地dns服务器或者host中绑定域名跟主机关系访问，我这里没有配置SSL证书，如果你有这个需求，需要自己单独配置。

到此，针对手动部署的全部过程就此结束，本次搭建的服务是比较新的版本，可能相互依赖中会有未知问题，尽量版本保持一致。
