static pod 만들기

API 서버 없이 트정 노드에 있는 kubelet 데몬에 의해 직접관리  /etc/kubernetes/manifests/ 디렉토리에 k8s yaml 파일을 저장 시 적용됨 static pod 디렉토리 구성 # vi /var/lib/kubelet/config.yaml ... staticPodPath: /etc/kuburnetes/manifests 디렉토리 수정시 kubelet 데몬 재실행  # systemctl restart kubelet

 

# cat /var/lib/kubelet/config.yaml  apiVersion: kubelet.config.k8s.io/v1beta1 authentication:   anonymous:     enabled: false   webhook:     cacheTTL: 0s     enabled: true   x509:     clientCAFile: /etc/kubernetes/pki/ca.crt authorization:   mode: Webhook   webhook:     cacheAuthorizedTTL: 0s     cacheUnauthorizedTTL: 0s cgroupDriver: systemd clusterDNS: - 10.96.0.10 clusterDomain: cluster.local containerRuntimeEndpoint: "" cpuManagerReconcilePeriod: 0s evictionPressureTransitionPeriod: 0s fileCheckFrequency: 0s healthzBindAddress: 127.0.0.1 healthzPort: 10248 httpCheckFrequency: 0s imageMinimumGCAge: 0s kind: KubeletConfiguration logging:   flushFrequency: 0   options:     json:       infoBufferSize: "0"   verbosity: 0 memorySwap: {} nodeStatusReportFrequency: 0s nodeStatusUpdateFrequency: 0s resolvConf: /run/systemd/resolve/resolv.conf rotateCertificates: true runtimeRequestTimeout: 0s shutdownGracePeriod: 0s shutdownGracePeriodCriticalPods: 0s staticPodPath: /etc/kubernetes/manifests       <<<<  streamingConnectionIdleTimeout: 0s syncFrequency: 0s volumeStatsAggPeriod: 0s

worker1 에서 

# cd /etc/kubernetes/manifests/ # vi nginx.yaml

 

apiVersion: v1 kind: Pod metadata:   creationTimestamp: null   labels:     run: pod-nginx   name: pod-nginx spec:   containers:   - image: nginx:1.14     name: pod-nginx     ports:     - containerPort: 80       protocol: TCP

저장만 하고 나와도 

Every 2.0s: kubectl get pods -n default -o wide                                                          master: Wed Sep  6 09:55:30 2023

NAME                READY   STATUS    RESTARTS   AGE     IP            NODE      NOMINATED NODE   READINESS GATES
pod-nginx-worker1   1/1     Running   0          4m24s   10.101.1.76   worker1   <none>           <none>
생성된걸 볼수있다.

 

master에도 

# cd /etc/kubernetes/manifests/ 똑같은 nginx.yaml  파일을 생성만 해줘도

Every 2.0s: kubectl get pods -n default -o wide                                                          master: Wed Sep  6 09:56:28 2023 NAME                READY   STATUS    RESTARTS   AGE     IP            NODE      NOMINATED NODE   READINESS GATES pod-nginx-master    1/1     Running   0          3m21s   10.101.1.3    master                pod-nginx-worker1   1/1     Running   0          5m21s   10.101.1.76   worker1

생성된걸 확인할수 있다 .
