我们不使用 Deployment 的滚动更新能力,而是为每个服务的每个版本,都创建不同的 Deployment + HPA + PodDisruptionBudget,这是为了方便做金丝雀/灰度发布 我们的服务可能会使用 IngressController / Service Mesh 来进行服务的负载均衡、流量切分 下面先给出一个 Deployment + HPA + PodDisruptionBudget 的 demo,后面再...
kubectl rollout status deployment/(name of deployment) ->获取部署状态 kubectl set image deployment/helloworld-deployment docker-demo=docker-demo:2 -> 使用版本号为 2 的新镜像运行 docker-demo kubectl edit deployment/helloworld-deployment -> 编辑部署对象 kubectl rollout status deployment/helloworld-deployme...
Doing this instructs Kubernetes to always prevent the drain event from deteriorating availability further when the final state results in less than the number of Pods you’ve specified for that Deployment. Learn more aboutPod Disruption Budgets here. ...
for cloud-native environments. Since Kubernetes plays a critical role in managing who and what could be done with containerized workloads, security should be well-understood and managed. It is therefore essential to use the right deployment architecture and security best practices for all deployments...
kubectlapply-fdeployment.yaml--record 带了这个选项之后,每次升级的时都会保存到部署的日志里面,这样就提供了回滚一个变更的能力。 多使用描述性的标签label 因为标签可以是任意的键值对,其表达力非常强。参考下图,以有名字为'Nifty‘的应用部署到四个容器里面。 通过选择BE标签你可以挑选出后端容器。
in order to recommend how to set your resource requests and limits. (While the VPA can actually set limits for you, it is often best to use the VPA engine only to provide recommendations.) Essentially, the tool creates a VPA for each deployment in a namespace and then queries that VPA ...
2. 相对于Deployment和ReplicaSet的优势 相比于Deployment和ReplicaSet控制器,StatefulSet控制器在部署有状态应用方面有以下优势: 稳定的网络标识:StatefulSet为有状态应用的Pod提供了稳定的网络标识,使得应用内部通信和数据交换更加简单和可靠。 有序部署和扩展:StatefulSet按顺序部署和扩展Pod,保证了应用的有序性和稳定性。

Finally, it’s common to run logging agents on every active node in your cluster. This ubiquitous deployment of logging means the agent can run as aDaemonSetsince it ensures all nodes run copies of a given pod. Unfortunately, these collection daemons do have a resource cost since they’re ...
