mkdir workspace && cd $_
kubectl get node

 

kubectl run nginx-pod --image=nginx # pending > ContainerCreating > Running
kubectl get pod

 

그런데 여기서 ip 이슈로 에러가 뜨는 경우가 생김..

# kubectl delete -f https://raw.githubusercontent.com/projectcalico/calico/v3.27.0/manifests/calico.yaml

# yum install -y wget
# wget https://raw.githubusercontent.com/projectcalico/calico/v3.27.0/manifests/calico.yaml

# vi calico.yaml
  imagePullSecrets:
  - name: dockersecret

# kubectl apply -f calico.yaml

# kubectl create secret docker-registry dockersecret --docker-username=<dockerhub id> --docker-password=<dockerhub password> --docker-email=<email>

# kubectl apply -f https://raw.githubusercontent.com/projectcalico/calico/v3.27.0/manifests/calico.yaml
# kubectl get pod --all-namespaces

 

 

 

 

 

 

kubectl get secrets
kubectl edit sa default

 

다시 해보자!!

kubectl run nginx-pod --image=nginx
kubectl get pod

 

 

kubectl get service
kubectl expose pod nginx-pod --name clusterip --type=ClusterIP --port 80
kubectl expose pod nginx-pod --name nodeport --type=NodePort --port 80
kubectl expose pod nginx-pod --name loadbalancer --type=LoadBalancer --external-ip 192.168.0.29 --port 80
