一、快速入门 1、关闭防火墙 systemctl disable firewalld systemctl stop firewalld 2、安装etcd和kubernetes软件 yum update yum install -y etcd kubernetes 3、启动服务 systemctl start etcd systemctl start docker systemctl start kube-apiserver systemctl start kube-controller-manager systemctl start kube-scheduler systemctl start kubelet systemctl start kube-proxy 4、配置 A、tomcat配置 a、mkdir /usr/local/k8s b、cd /usr/local/k8s c、vim mytomcat.rc.yaml d、kubectl create -f mytomcat.rc.yaml e、vim mytomcat.svc.yaml f、kubectl create -f mytomcat.svc.yaml g、kubectl get pods h、kubectl get svc 5、问题解决 A、kubectl get pods(ContainerCreating问题解决) B、kubectl get pods(No resources found问题解决) vim /etc/kubernetes/apiserver KUBE_ADMISSION_CONTROL删除ServiceAccount,选项 systemctl restart kube-apiserver 备注: 1、mytomcat.rc.yaml apiVersion: v1 kind: ReplicationController metadata: name: mytomcat spec: replicas: 2 selector: app: mytomcat template: metadata: labels: app: mytomcat spec: containers: - name: mytomcat image: tomcat:8-jre8 ports: - containerPort: 8080 2、mytomcat.svc.yaml apiVersion: v1 kind: Service metadata: name: mytomcat spec: type: NodePort ports: - port: 8080 nodePort: 30001 selector: app: mytomcat
