初试 Kubernetes -集群搭建

bash gcr-mirror-install.sh

kubeadm init --pod-network-cidr=192.168.0.0/16 --kubernetes-version=v1.11.2

You can now join any number of machines by running the following on each node
as root:
kubeadm join --token <token> <master-ip>:<master-port> --discovery-token-ca-cert-hash sha256:<hash>

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

export KUBECONFIG=/etc/kubernetes/admin.conf

bash quay-mirror-install.sh

kubectl apply -f https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/rbac-kdd.yaml
kubectl apply -f https://docs.projectcalico.org/v3.1/getting-started/kubernetes/installation/hosted/kubernetes-datastore/calico-networking/1.7/calico.yaml

bash quay-mirror-install.sh

kubeadm join --token <token> <master-ip>:<master-port> --discovery-token-ca-cert-hash 

#查看集群节点
kubectl get nodes
#列出服务
kubectl get services
#列出 pods
kubectl get pods --all-namespaces            
kubectl get pods -o wide
kubectl get pods --include-uninitialized
kubectl get pods --sort-by='.status.containerStatuses[0].restartCount'
#列出 deployment
kubectl get deployment my-dep
#应用manifest
kubectl create -f ./my-manifest.yaml 
kubectl delete -f ./my-manifest.yaml 
#获取manifests文档
kubectl explain pods,svc
#获取nodes pods信息
kubectl describe nodes my-node
kubectl describe pods my-pod
