< pre > < code class = "lang-bash" > kubectl autoscale deployment foo --min=2 --max=5 --cpu-percent=80
< / code > < / pre >
< p > 为 Deployment foo创 建 一 个 autoscaler， 当 Pod的 CPU利 用 率 达 到 80%的 时 候 ， RC的 replica数 在 2到 5之 间 。 该 命 令 的 详 细 使 用 文 档 见 < a href = "https://kubernetes.io/docs/user-guide/kubectl/v1.6/#autoscale" target = "_blank" > https://kubernetes.io/docs/user-guide/kubectl/v1.6/#autoscale< / a > 。 < / p >

< p > < strong > 注 意 < / strong > ： 如 果 为 ReplicationController创 建 HPA的 话 ， 无 法 使 用 rolling update， 但 是 对 于 Deployment来 说 是 可 以 的 ， 因 为 Deployment在 执 行 rolling update的 时 候 会 自 动 创 建 新 的 ReplicationController。 < / p >
< h2 id = "什么是-horizontal-pod-autoscaling？" > 什 么 是 Horizontal Pod Autoscaling？ < / h2 >
< p > 利 用 Horizontal Pod Autoscaling， kubernetes 能 够 根 据 监 测 到 的 CPU 利 用 率 （ 或 者 在 alpha 版 本 中 支 持 的 应 用 提 供 的 metric） 自 动 的 扩 容 replication controller， deployment 和 replica set。 < / p >
< p > Horizontal Pod Autoscaler 作 为 kubernetes API resource 和 controller 的 实 现 。 Resource 确 定 controller 的 行 为 。 Controller 会 根 据 监 测 到 用 户 指 定 的 目 标 的 CPU 利 用 率 周 期 性 得 调 整 replication controller 或 deployment 的 replica 数 量 。 < / p >
< h2 id = "horizontal-pod-autoscaler-如何工作？" > Horizontal Pod Autoscaler 如 何 工 作 ？ < / h2 >
< p > Horizontal Pod Autoscaler 由 一 个 控 制 循 环 实 现 ， 循 环 周 期 由 controller manager 中 的 < code > --horizontal-pod-autoscaler-sync-period< / code > 标 志 指 定 （ 默 认 是 30 秒 ） 。 < / p >
< p > 在 每 个 周 期 内 ， controller manager 会 查 询 HorizontalPodAutoscaler 中 定 义 的 metric 的 资 源 利 用 率 。 Controller manager 从 resource metric API（ 每 个 pod 的 resource metric） 或 者 自 定 义 metric API（ 所 有 的 metric） 中 获 取 metric。 < / p >
< ul >
< li > 每 个 Pod 的 resource metric（ 例 如 CPU） ， controller 通 过 resource metric API 获 取 HorizontalPodAutoscaler 中 定 义 的 每 个 Pod 中 的 metric。 然 后 ， 如 果 设 置 了 目 标 利 用 率 ， controller 计 算 利 用 的 值 与 每 个 Pod 的 容 器 里 的 resource request 值 的 百 分 比 。 如 果 设 置 了 目 标 原 始 值 ， 将 直 接 使 用 该 原 始 metric 值 。 然 后 controller 计 算 所 有 目 标 Pod 的 利 用 率 或 原 始 值 （ 取 决 于 所 指 定 的 目 标 类 型 ） 的 平 均 值 ， 产 生 一 个 用 于 缩 放 所 需 replica 数 量 的 比 率 。 请 注 意 ， 如 果 某 些 Pod 的 容 器 没 有 设 置 相 关 的 resource request ， 则 不 会 定 义 Pod 的 CPU 利 用 率 ， 并 且 Aucoscaler 也 不 会 对 该 metric 采 取 任 何 操 作 。 有 关 自 动 缩 放 算 法 如 何 工 作 的 更 多 细 节 ， 请 参 阅 < a href = "https://git.k8s.io/community/contributors/design-proposals/horizontal-pod-autoscaler.md#autoscaling-algorithm" target = "_blank" > 自 动 缩 放 算 法 设 计 文 档 < / a > 。 < / li >
< li > 对 于 每 个 Pod 自 定 义 的 metric， controller 功 能 类 似 于 每 个 Pod 的 resource metric， 只 是 它 使 用 原 始 值 而 不 是 利 用 率 值 。 < / li >
< li > 对 于 object metric， 获 取 单 个 度 量 （ 描 述 有 问 题 的 对 象 ） ， 并 与 目 标 值 进 行 比 较 ， 以 产 生 如 上 所 述 的 比 率 。 < / li >
< / ul >
< p > HorizontalPodAutoscaler 控 制 器 可 以 以 两 种 不 同 的 方 式 获 取 metric ： 直 接 的 Heapster 访 问 和 REST 客 户 端 访 问 。 < / p >
< p > 当 使 用 直 接 的 Heapster 访 问 时 ， HorizontalPodAutoscaler 直 接 通 过 API 服 务 器 的 服 务 代 理 子 资 源 查 询 Heapster。 需 要 在 集 群 上 部 署 Heapster 并 在 kube-system namespace 中 运 行 。 < / p >
< p > 有 关 REST 客 户 端 访 问 的 详 细 信 息 ， 请 参 阅 < a href = "https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale.md#prerequisites" target = "_blank" > 支 持 自 定 义 度 量 < / a > 。 < / p >
< p > Autoscaler 访 问 相 应 的 replication controller， deployment 或 replica set 来 缩 放 子 资 源 。 < / p >
< p > Scale 是 一 个 允 许 您 动 态 设 置 副 本 数 并 检 查 其 当 前 状 态 的 接 口 。 < / p >
< p > 有 关 缩 放 子 资 源 的 更 多 细 节 可 以 在 < a href = "https://git.k8s.io/community/contributors/design-proposals/horizontal-pod-autoscaler.md#scale-subresource" target = "_blank" > 这 里 < / a > 找 到 。 < / p >
< h2 id = "api-object" > API Object< / h2 >
< p > Horizontal Pod Autoscaler 是 kubernetes 的 < code > autoscaling< / code > API 组 中 的 API 资 源 。 当 前 的 稳 定 版 本 中 ， 只 支 持 CPU 自 动 扩 缩 容 ， 可 以 在 < code > autoscaling/v1< / code > API 版 本 中 找 到 。 < / p >
< p > 在 alpha 版 本 中 支 持 根 据 内 存 和 自 定 义 metric 扩 缩 容 ， 可 以 在 < code > autoscaling/v2alpha1< / code > 中 找 到 。 < code > autoscaling/v2alpha1< / code > 中 引 入 的 新 字 段 在 < code > autoscaling/v1< / code > 中 是 做 为 annotation 而 保 存 的 。 < / p >
< p > 关 于 该 API 对 象 的 更 多 信 息 ， 请 参 阅 < a href = "https://git.k8s.io/community/contributors/design-proposals/horizontal-pod-autoscaler.md#horizontalpodautoscaler-object" target = "_blank" > HorizontalPodAutoscaler Object< / a > 。 < / p >
< h2 id = "在-kubectl-中支持-horizontal-pod-autoscaling" > 在 kubectl 中 支 持 Horizontal Pod Autoscaling< / h2 >
< p > Horizontal Pod Autoscaler 和 其 他 的 所 有 API 资 源 一 样 ， 通 过 < code > kubectl< / code > 以 标 准 的 方 式 支 持 。 < / p >
< p > 我 们 可 以 使 用 < code > kubectl create< / code > 命 令 创 建 一 个 新 的 autoscaler。 < / p >
< p > 我 们 可 以 使 用 < code > kubectl get hpa< / code > 列 出 所 有 的 autoscaler， 使 用 < code > kubectl describe hpa< / code > 获 取 其 详 细 信 息 。 < / p >
< p > 最 后 我 们 可 以 使 用 < code > kubectl delete hpa< / code > 删 除 autoscaler。 < / p >
< p > 另 外 ， 可 以 使 用 < code > kubectl autoscale< / code > 命 令 ， 很 轻 易 的 就 可 以 创 建 一 个 Horizontal Pod Autoscaler。 < / p >
< p > 例 如 ， 执 行 < code > kubectl autoscale rc foo — min=2 — max=5 — cpu-percent=80< / code > 命 令 将 为 replication controller < em > foo< / em > 创 建 一 个 autoscaler， 目 标 的 CPU 利 用 率 是 < code > 80%< / code > ， replica 的 数 量 介 于 2 和 5 之 间 。 < / p >
< p > 关 于 < code > kubectl autoscale< / code > 的 更 多 信 息 请 参 阅 < a href = "https://kubernetes.io/docs/user-guide/kubectl/v1.6/#autoscale" target = "_blank" > 这 里 < / a > 。 < / p >
< h2 id = "滚动更新期间的自动扩缩容" > 滚 动 更 新 期 间 的 自 动 扩 缩 容 < / h2 >
< p > 目 前 在 Kubernetes中 ， 可 以 通 过 直 接 管 理 replication controller 或 使 用 deployment 对 象 来 执 行 < a href = "https://kubernetes.io/docs/tasks/run-application/rolling-update-replication-controller" target = "_blank" > 滚 动 更 新 < / a > ， 该 deployment 对 象 为 您 管 理 基 础 replication controller。 < / p >
< p > Horizontal Pod Autoscaler 仅 支 持 后 一 种 方 法 ： Horizontal Pod Autoscaler 被 绑 定 到 deployment 对 象 ， 它 设 置 deployment 对 象 的 大 小 ， deployment 负 责 设 置 底 层 replication controller 的 大 小 。 < / p >
< p > Horizontal Pod Autoscaler 不 能 使 用 直 接 操 作 replication controller 进 行 滚 动 更 新 ， 即 不 能 将 Horizontal Pod Autoscaler 绑 定 到 replication controller， 并 进 行 滚 动 更 新 （ 例 如 使 用 < code > kubectl rolling-update< / code > ） 。 < / p >
< p > 这 不 行 的 原 因 是 ， 当 滚 动 更 新 创 建 一 个 新 的 replication controller 时 ， Horizontal Pod Autoscaler 将 不 会 绑 定 到 新 的 replication controller 上 。 < / p >
< h2 id = "支持多个-metric" > 支 持 多 个 metric< / h2 >
< p > Kubernetes 1.6 中 增 加 了 支 持 基 于 多 个 metric 的 扩 缩 容 。 您 可 以 使 用 < code > autoscaling/v2alpha1< / code > API 版 本 来 为 Horizontal Pod Autoscaler 指 定 多 个 metric。 然 后 Horizontal Pod Autoscaler controller 将 权 衡 每 一 个 metric， 并 根 据 该 metric 提 议 一 个 新 的 scale。 在 所 有 提 议 里 最 大 的 那 个 scale 将 作 为 最 终 的 scale。 < / p >
< h2 id = "支持自定义-metric" > 支 持 自 定 义 metric< / h2 >
< p > < strong > 注 意 ： < / strong > Kubernetes 1.2 根 据 特 定 于 应 用 程 序 的 metric ， 通 过 使 用 特 殊 注 释 的 方 式 ， 增 加 了 对 缩 放 的 alpha 支 持 。 < / p >
< p > 在 Kubernetes 1.6中 删 除 了 对 这 些 注 释 的 支 持 ， 有 利 于 < code > autoscaling/v2alpha1< / code > API。 虽 然 旧 的 收 集 自 定 义 metric 的 旧 方 法 仍 然 可 用 ， 但 是 这 些 metric 将 不 可 供 Horizontal Pod Autoscaler 使 用 ， 并 且 用 于 指 定 要 缩 放 的 自 定 义 metric 的 以 前 的 注 释 也 不 在 受 Horizontal Pod Autoscaler 认 可 。 < / p >
< p > Kubernetes 1.6增 加 了 在 Horizontal Pod Autoscale r中 使 用 自 定 义 metric 的 支 持 。 < / p >
< p > 您 可 以 为 < code > autoscaling/v2alpha1< / code > API 中 使 用 的 Horizontal Pod Autoscaler 添 加 自 定 义 metric 。 < / p >
< p > Kubernetes 然 后 查 询 新 的 自 定 义 metric API 来 获 取 相 应 自 定 义 metric 的 值 。 < / p >
< h2 id = "前提条件" > 前 提 条 件 < / h2 >
< p > 为 了 在 Horizontal Pod Autoscaler 中 使 用 自 定 义 metric， 您 必 须 在 您 集 群 的 controller manager 中 将 < code > --horizontal-pod-autoscaler-use-rest-clients< / code > 标 志 设 置 为 true。 然 后 ， 您 必 须 通 过 将 controller manager 的 目 标 API server 设 置 为 API server aggregator（ 使 用 < code > --apiserver< / code > 标 志 ） ， 配 置 您 的 controller manager 通 过 API server aggregator 与 API server 通 信 。 Resource metric API和 自 定 义 metric API 也 必 须 向 API server aggregator 注 册 ， 并 且 必 须 由 集 群 上 运 行 的 API server 提 供 。 < / p >
< p > 您 可 以 使 用 Heapster 实 现 resource metric API， 方 法 是 将 < code > --api-server< / code > 标 志 设 置 为 true 并 运 行 Heapster。 单 独 的 组 件 必 须 提 供 自 定 义 metric API（ 有 关 自 定 义 metric API的 更 多 信 息 ， 可 从 < a href = "https://github.com/kubernetes/metrics" target = "_blank" > k8s.io/metrics repository< / a > 获 得 ） 。 < / p >
