Kubernetes - 10.static pod

api서버 없이 특정 노드에 있는 kubelet 데몬에 의해 직접 관리
/etc/kubernetes/manifests/ 디렉토리에 k8s yaml 파일을 저장 시 적용됨

vi /var/lib/kubelet/config.yaml
...
staticPodPath: /etc/kubernetes/manifests

디렉터리 수정시 kubelet 데몬 재실행
systemctl restart kubelet

ssh kube-node1

cat /var/lib/kubelet/config.yaml

cd /etc/kubernetes/manifests/
ls

vi nginx.yaml
apiVersion: v1
kind: Pod
metadata:
  labels:
  name: nginx-pod
spec:
  containers:
  - image: nginx:1.14
    name: nginx-container
    ports:
    - containerPort: 80
:wq!

저장하는 순간 파드가 생성됨

파드 삭제하려면 해당 노드에 있는 yaml파일을 삭제해야함

만약 마스터(control-plane)에 만들게되면 워커노드이나 노드2중에 어딘가에 생성이됨(api이용해서 생성하는것과 같음)
