k8s deployment更新、回滚、扩容

• 更新deployment

 kubectl set image deploy job-deploy -n xiao job-deploy=nginx:v1.0 --record

• deployment查看更新记录

kubectl rollout history deploy job-deploy  -n xiao

• deployment回滚

kubectl rollout undo deploy job-deploy -n xiao

• 查看详细版本信息

kubectl rollout history deploy job-deploy -n xiao --revision=6

• 更新到某个版本

kubectl rollout undo deploy job-deploy -n xiao --to-revision=6

• 暂停更新与恢复更新（当你需要更新deployment的多个地方，但希望deployment的更新只执行一次，可以先暂停更新，等修改完之后再恢复更新，此时deployment才会进行真正的更新操作）

kubectl rollout pause deploy job-deploy -n xiao
kubectl rollout resume deploy job-deploy -n xiao

• 扩容

kubectl scale --replicas=3 deploy job-deploy -n xiao
