创建大规模集群 |
支持规格
在 {{< param "version" >}},Kubernetes 支持最多 5000 节点规模的集群。 更具体地说,我们支持满足以下 所有 标准的配置:
- 不超过 5000 节点
- 总共不超过 15000 个 pod
- 总共不超过 300000 个容器
- 每个节点不超过 100 个 pod
- TOC {{< toc >}}
创建
集群是一组运行 Kubernetes 代理组件的节点(物理或虚拟机),它们被 master(集群管理平面)所管理。
一般来说,集群的节点数量通过平台相关的 config-default.sh 文件中的 NUM_NODES 值来控制,(例如,详见 [GCE's config-default.sh](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/gce/config-default.sh))。
对很多云提供商来说,单纯地修改 NUM_NODES 为一个非常大的值,可能会导致集群的创建脚本失败。 例如,在 GCE 中部署时,会因配额不足,导致集群启动失败。
当建立一个大型的 Kubernetes 集群,以下几个问题必须考虑。
配额问题
为了避免出现配额问题,当创建包含大量节点的集群时,考虑:
- 提高相关配额,如 CPU,IP 等。
- 如,在 GCE 中,你可能需要提高以下资源的配额:
- CPU
- 虚机实例
- 磁盘
- 使用的 IP 地址
- 防火墙规则
- 转发规则
- 路由
- 对象池
- 如,在 GCE 中,你可能需要提高以下资源的配额:
- 设置创建脚本,使其以较小的规模分批次拉起新的节点,并在其间设置一定的等待时间,因为一些云供应商可能对虚机的创建速率进行了限制。
Etcd 存储
为了提升大规模集群的性能,我们将事件对象存储到独立的 etcd 实例中。
创建集群时,当前的 salt 脚本:
- 启动并配置额外的 etcd 实例
- 配置 api-server,将该 etcd 实例用于事件对象的存储
管理节点和组件的规格
在 GCE/Google Kubernetes Engine 或 AWS 平台中, kube-up 会根据集群的节点规模合理地设置管理节点的规格。 在其他云平台上,用户需要手动配置。 作为参考,GCE 使用的规格为:
- 1-5 节点: n1-standard-1
- 6-10 节点: n1-standard-2
- 11-100 节点: n1-standard-4
- 101-250 节点: n1-standard-8
- 251-500 节点: n1-standard-16
- 500 节点以上: n1-standard-32
AWS 使用的规格为:
- 1-5 节点: m3.medium
- 6-10 节点: m3.large
- 11-100 节点: m3.xlarge
- 101-250 节点: m3.2xlarge
- 251-500 节点: c4.4xlarge
- 500 节点以上: c4.8xlarge
注意,管理节点的规格只会在集群创建时进行设置,后续集群规模发生变化(如手动增删节点或集群自动扩缩容)后不会再调整。
插件的资源占用
为防止[集群插件](https://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons)耗尽节点资源引起内存泄漏或其他资源问题, Kubernetes 设置了插件容器资源的上限,来限制其对 CPU 和内存资源的占用(参考 PR #10653 和 #10778)。
例如:
containers:
- name: fluentd-cloud-logging
image: k8s.gcr.io/fluentd-gcp:1.16
resources:
limits:
cpu: 100m
memory: 200Mi
除 Heapster 外,这些限制是静态的,基于 4 个节点规模的集群上运行的插件所采集的数据(详见 #10335)。 而实际大规模集群中插件所消耗的资源要多得多(详见 #5880)。 所以如果部署大规模集群时不对这些值进行调整,插件可能会因为资源占用达到上限而不断被杀死。
为了避免集群插件的资源问题,创建多节点的集群时,考虑以下几点:
- 当扩大集群规模时,如果涉及,相应扩大以下插件的内存和 CPU 限制(通过一个实例处理整个集群,因此其内存和 CPU 使用量往往与集群的大小/负载成比例增长):
- [InfluxDB 和 Grafana](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/cluster-monitoring/influxdb/influxdb-grafana-controller.yaml)
- [kubedns, dnsmasq, 和 sidecar](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/dns/kubedns-controller.yaml.in)
- [Kibana](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/fluentd-elasticsearch/kibana-controller.yaml)
- 当扩大集群规模时,如果涉及,相应扩大以下插件副本数(每个组件有多个副本,因此增加副本将有助于处理增加的负载,但是,由于每个副本的负载也略有增加,也应考虑提高 CPU / 内存上限):
- [elasticsearch](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/fluentd-elasticsearch/es-controller.yaml)
- 当扩大集群规模时,如果涉及,略微扩大以下插件的内存和 CPU 限制(每个节点一个副本, 但是 CPU / 内存使用随集群的大小/负载增长变化不明显):
- [FluentD with ElasticSearch Plugin](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/fluentd-elasticsearch/fluentd-es-ds.yaml)
- [FluentD with GCP Plugin](http://releases.k8s.io/{{< param "githubbranch" >}}/cluster/addons/fluentd-gcp/fluentd-gcp-ds.yaml)
Heapster 的资源限制是基于集群的初始规模动态设置的 ( 参考 #16185 和 #22940)。 当发现 Heapster 资源耗尽,应考虑调整计算 Heapster 内存请求的公式(参考上述 PR)。
关于如何检测插件是否达到资源上限 参考 计算资源的故障排除章节。
将来,我们期望基于集群规模来设置集群插件的资源限制,并且在集群规模增长或缩小时能够动态调整。 欢迎提出 PR 来实现这些特性。
启动时允许部分失败
因为种种原因(详见 #18969),在 NUM_NODES 值很大的情况下执行
kube-up.sh, 可能因为其中一小部分节点没有正常启动而失败。
这时我们有两种选择:重启集群(kube-down.sh 然后再 kube-up.sh),或者在执行 kube-up.sh 之前,
将环境变量 ALLOWED_NOTREADY_NODES 设置为合适的值。 这将允许 kube-up.sh 以少于 NUM_NODES 的节点数量启动集群。 依据失败的具体原因,另外的节点可能在后面加入集群,或者集群节点数量将保持在 NUM_NODES - ALLOWED_NOTREADY_NODES。
