k3s 에 cloudflare ddns 업데이터 적용

기존에 dnszi 에서 사용하던 ddns 업데이트 이후 cloudflare 로 옮긴후 적용이 필요했다.

 

먼저 k3s 에 인증키 생성

gglabadmin@k3s-node1:/k8s/common/cloudflare$ cat ddns-secret.yaml 
apiVersion: v1
kind: Secret
metadata:
  name: cloudflare-api-token
  namespace: default
type: Opaque
stringData:
  token: "api토큰"

 

다음으로

proxy 할것과 안할것을 구분해서 두개의 설정 파일 준비

 

[DNS 만 연결]

gglabadmin@k3s-node1:/k8s/common/cloudflare$ cat ddns-direct-deployment.yaml 
apiVersion: apps/v1
kind: Deployment
metadata:
  name: cloudflare-ddns-direct
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      app: cloudflare-ddns
  template:
    metadata:
      labels:
        app: cloudflare-ddns
    spec:
      containers:
      - name: ddns
        image: favonia/cloudflare-ddns:latest
        env:
        - name: CLOUDFLARE_API_TOKEN
          valueFrom:
            secretKeyRef:
              name: cloudflare-api-token
              key: token
        - name: DOMAINS
          value: "도메인주소"
        - name: PROXIED
          value: "false"
        - name: UPDATE_CRON
          value: "@every 1h"
        - name: IP6_PROVIDER
          value: "none"
        - name: DETECTION_TIMEOUT
          value: "15s"
        # 컨테이너 자원 제한 (선택 사항)
        resources:
          limits:
            memory: "64Mi"
            cpu: "100m"

        - name: PROXIED

잘 올라왔나?

gglabadmin@k3s-node1:/k8s/common/cloudflare$ sudo kubectl get pods -l app=cloudflare-ddns
NAME                                      READY   STATUS    RESTARTS   AGE
cloudflare-ddns-direct-689fbfbf9c-nhn5r   1/1     Running   0          7m49s
cloudflare-ddns-proxied-d766fb866-59pk6   1/1     Running   0          7m44s

 

파드는 1개씩만 있으면 되겠지

 

로그를 보자.
