Docker Kubernetes 容器更新与回滚
环境：
创建环境：
更新升级
方案一：管理节点：滚动升级镜像。
kubectl set image deployment nginx-deployment nginx=nginx:1.11
kubectl set image 资源类型/资源名称 容器名称=镜像版本
方案二：管理节点：修改原yaml配置文件重新加载完成滚动升级
kubectl apply -f nginx-deployment.yaml
管理节点：查看升级情况
命令：kubectl describe deployment nginx-deployment # 镜像已更新 Image: nginx:1.11 Type Reason Age From Message ---- ------ ---- ---- ------- # 扩容版本 Normal ScalingReplicaSet 24m deployment-controller Scaled up replica set nginx-deployment-845cfc7fb9 to 3 Normal ScalingReplicaSet 49s deployment-controller Scaled up replica set nginx-deployment-7ff5df4cfb to 1 # 缩容版本 Normal ScalingReplicaSet 34s deployment-controller Scaled down replica set nginx-deployment-845cfc7fb9 to 2 # 扩容版本 Normal ScalingReplicaSet 34s deployment-controller Scaled up replica set nginx-deployment-7ff5df4cfb to 2 # 缩容版本 Normal ScalingReplicaSet 18s deployment-controller Scaled down replica set nginx-deployment-845cfc7fb9 to 1 # 扩容版本 Normal ScalingReplicaSet 18s deployment-controller Scaled up replica set nginx-deployment-7ff5df4cfb to 3 # 缩容版本 Normal ScalingReplicaSet 15s deployment-controller Scaled down replica set nginx-deployment-845cfc7fb9 to 0

版本回滚
管理节点：回滚到上一个版本
kubectl rollout undo deployment nginx-deployment
kubectl rollout undo 资源类型 资源名称
管理节点：指定版本回滚
kubectl rollout undo deployment/nginx-deployment --to-revision=3
kubectl rollout undo 资源类型 资源名称 --to-revision=版本号
注：kubectl rollout history 资源类型 资源名称 查看的版本号。
管理节点：查看回滚情况
命令：kubectl rollout history deployment/nginx-deployment deployments "nginx-deployment" REVISION CHANGE-CAUSE 1 <none> 2 <none> 4 <none> 5 <none> 注：将还原版本覆盖，并生成新的版本号。
