2 青云 QingCloud 容器器及 Kubernetes 实践王渊命青云 QingCloud 容器器平台负责人

3 当我们谈论容器器时我们在谈论什什么?

4 容器器的两个视角资源隔离应用封装

5 容器器生态圈现状容器器技术一家独大百花齐放 Docker, Rocket, Mesos Universal container, LXC, Hyper Container 调度系统三足鼎立 Kubernetes, Mesos, Swarm 2016 年年容器器技术思考 :Docker, Kubernetes, Mesos 将走向何方?

6 资源视角应用视角

7 资源视角 QingCloud IaaS 调度系统支持 Container Instance Virtual Instance Container Instance Applica6ons Guest OS Applica6ons Hypervisor Host OS Hardware

8 应用视角 AppCenter 支持 "container": { "type": "docker", "image": "zookeeper" } Docker 镜像

9 应用视角 AppCenter 支持各种容器器编排系统

10 网络存储负载均衡弹性

11 Internet Kubernetes 概览 Firewall kubectl (user commands) Node kubelet Proxy docker APIs scheduling actuator authentication authorization REST (pods,services, rep.contollers) cadvisor cadvisor container cadvisor container cadvisor Node kubelet Proxy Scheduler Scheduler controller manager docker Master components Distributed Watchable Storage (implemented via etcd) cadvisor cadvisor container cadvisor container cadvisor

12 Kubernetes 抽象概念 Service StatefulSet(PetSet) Job PersistentVolume ReplicaSet(ReplicationController) PersistentVolumeClaim Deployment Namespace DaemonSet Label/Selector

13 Kubernetes 网络容器器之间可以直接互通, 不不需要 NAT 节点可以喝喝容器器直接互通, 不不需要 NAT 容器器看到自己的 IP 应该和其他容器器看到的一样 CNI (Container Network Interface) - Flannel - Calico - Contiv ClusterIP - Virtual IP - Iptables

14 Kubernetes 网络之 ClusterIP { "kind": "Service", "apiversion": "v1", "metadata": { "name": "my-service" }, "spec": { "selector": { "app": "MyApp" }, "ports": [ { "protocol": "TCP", "port": 80, "targetport": 9376 } ], "clusterip": " ", "type": LoadBalancer /NodePort" } }

15 Kubernetes 网络之 flannel Discovery etcd kube-subnet-mgr Backend vxlan aws-vpc

19 Kubernetes 存储 Controller Manager scheduler Container(MySQL) X Container(MySQL) Node1 LocalDisk Node2 LocalDisk Controller Manager scheduler Container(MySQL) OK Container(MySQL) Node1 Node2 DistributeDisk

20 Kubernetes 存储 DistributeDisk nfs ceph glusterfs PersistentVolume plugin - gcepersistentdisk - awselasticblockstore - qingcloudstore

21 Kubernetes 存储之 QingCloudStore PersistentVolume Plugin PersistentVolume StorageClass PersistentVolumeClaim

22 Kubernetes 存储之 QingCloudStore kind: PersistentVolume apiversion: v1 metadata: name: qingcloud-pv labels: type: qingcloud spec: capacity: storage: 10Gi accessmodes: - ReadWriteOnce qingcloudstore: volumeid: vol-caoxtgg3 fstype: ext4 kind: PersistentVolumeClaim apiversion: v1 metadata: name: qingcloud-pvc annotations: volume.beta.kubernetes.io/storage-class: qingcloud-storageclass spec: accessmodes: - ReadWriteOnce resources: requests: storage: 3Gi kind: StorageClass apiversion: storage.k8s.io/v1beta1 metadata: name: qingcloud-storageclass provisioner: kubernetes.io/qingcloud-volume parameters: type: "3"

23 Kubernetes 自动伸缩 Deployment kubectl autoscale deployment php-apache --cpu-percent=50 --min=1 --max=10 集群的自动伸缩 (TriggeredScaleUp Event) gcloud container clusters create mytestcluster \ zone=us-central1-b --enable-autoscaling --min-nodes=3 --max-nodes=10 --num-nodes=5

24 网络 (SDN Passthrough) 存储 (PersistentVolumePlugin) 负载均衡 (LB + SDN) 自动伸缩 (Event + IaaS API)

25 计划 7 月份公开试用 AppCenter 支持 Kubernetes 应用规范 Kubernetes 之上的服务
