< / ul >
< p > 除 资 源 不 足 的 情 况 外 ， 大 多 数 用 户 应 该 都 熟 悉 以 下 这 些 情 况 ； 它 们 不 是 特 定 于 Kubernetes 的 。 < / p >
< p > 我 们 称 这 些 情 况 为 ” 自 愿 中 断 “ 。 包 括 由 应 用 程 序 所 有 者 发 起 的 操 作 和 由 集 群 管 理 员 发 起 的 操 作 。 典 型 的 应 用 程 序 所 有 者 操 作 包 括 ： < / p >
< ul >

< li > 从 节 点 中 移 除 一 个 pod， 以 允 许 其 他 pod 使 用 该 节 点 。 < / li >
< / ul >
< p > 这 些 操 作 可 能 由 集 群 管 理 员 直 接 执 行 ， 也 可 能 由 集 群 管 理 员 或 集 群 托 管 提 供 商 自 动 执 行 。 < / p >
< p > 询 问 您 的 集 群 管 理 员 或 咨 询 您 的 云 提 供 商 或 发 行 文 档 ， 以 确 定 是 否 为 您 的 集 群 启 用 了 任 何 自 动 中 断 源 。 如 果 没 有 启 用 ， 您 可 以 跳 过 创 建 Pod Disruption Budget（ Pod 中 断 预 算 ） 。 < / p >

< p > 自 愿 中 断 的 频 率 各 不 相 同 。 在 Kubernetes 集 群 上 ， 根 本 没 有 自 愿 的 中 断 。 但 是 ， 您 的 集 群 管 理 员 或 托 管 提 供 商 可 能 会 运 行 一 些 导 致 自 愿 中 断 的 附 加 服 务 。 例 如 ， 节 点 软 件 更 新 可 能 导 致 自 愿 更 新 。 另 外 ， 集 群 （ 节 点 ） 自 动 缩 放 的 某 些 实 现 可 能 会 导 致 碎 片 整 理 和 紧 缩 节 点 的 自 愿 中 断 。 您 的 集 群 管 理 员 或 主 机 提 供 商 应 该 已 经 记 录 了 期 望 的 自 愿 中 断 级 别 （ 如 果 有 的 话 ） 。 < / p >
< p > Kubernetes 提 供 的 功 能 可 以 满 足 在 频 繁 地 自 动 中 断 的 同 时 运 行 高 可 用 的 应 用 程 序 。 我 们 称 之 为 “ 中 断 预 算 ” 。 < / p >
< h2 id = "中断预算的工作原理" > 中 断 预 算 的 工 作 原 理 < / h2 >
< p > 应 用 程 序 所 有 者 可 以 为 每 个 应 用 程 序 创 建 一 个 < code > PodDisruptionBudget< / code > 对 象 （ PDB） 。 PDB 将 限 制 在 同 一 时 间 自 愿 中 断 的 复 制 应 用 程 序 中 宕 机 的 Pod 的 数 量 。 例 如 ， 基 于 定 额 的 应 用 程 序 希 望 确 保 运 行 的 副 本 数 量 永 远 不 会 低 于 仲 裁 所 需 的 数 量 。 Web 前 端 可 能 希 望 确 保 提 供 负 载 的 副 本 的 数 量 永 远 不 会 低 于 总 数 的 某 个 百 分 比 。 < / p >
< p > 集 群 管 理 器 和 托 管 提 供 商 应 使 用 遵 循 < code > Pod Disruption Budgets< / code > 的 工 具 ， 方 法 是 调 用 < a href = "https://kubernetes.io/docs/tasks/administer-cluster/safely-drain-node/#the-eviction-api" target = "_blank" > Eviction API< / a > 而 不 是 直 接 删 除 Pod。 例 如 < code > kubectl drain< / code > 命 令 和 Kubernetes-on-GCE 集 群 升 级 脚 本 （ < code > cluster/gce/upgrade.sh< / code > ） 。 < / p >
< p > 当 集 群 管 理 员 想 要 排 空 节 点 时 ， 可 以 使 用 < code > kubectl drain< / code > 命 令 。 该 命 令 会 试 图 驱 逐 机 器 上 的 所 有 pod。 驱 逐 请 求 可 能 会 暂 时 被 拒 绝 ， 并 且 该 工 具 会 定 期 重 试 所 有 失 败 的 请 求 ， 直 到 所 有 的 pod 都 被 终 止 ， 或 者 直 到 达 到 配 置 的 超 时 时 间 。 < / p >
< p > PDB 指 定 应 用 程 序 可 以 容 忍 的 副 本 的 数 量 ， 相 对 于 应 该 有 多 少 副 本 。 例 如 ， 具 有 < code > spec.replicas： 5< / code > 的 Deployment 在 任 何 给 定 的 时 间 都 应 该 有 5 个 Pod。 如 果 其 PDB 允 许 在 某 一 时 刻 有 4 个 副 本 ， 那 么 驱 逐 API 将 只 允 许 仅 有 一 个 而 不 是 两 个 Pod 自 愿 中 断 。 < / p >
< p > 使 用 标 签 选 择 器 来 指 定 应 用 程 序 的 一 组 pod， 这 与 应 用 程 序 的 控 制 器 （ Deployment、 StatefulSet 等 ） 使 用 的 相 同 。 < / p >
< p > Pod 控 制 器 的 < code > .spec.replicas< / code > 计 算 “ 预 期 的 ” pod 数 量 。 使 用 对 象 的 < code > .metadata.ownerReferences< / code > 值 从 控 制 器 获 取 。 < / p >
< p > PDB 不 能 阻 止 < a href = "https://kubernetes.io/docs/concepts/workloads/pods/disruptions/#voluntary-and-involuntary-disruptions" target = "_blank" > 非 自 愿 中 断 < / a > 的 发 生 ， 但 是 它 们 确 实 会 影 响 预 算 。 < / p >
< p > 由 于 应 用 程 序 的 滚 动 升 级 而 被 删 除 或 不 可 用 的 Pod 确 实 会 计 入 中 断 预 算 ， 但 控 制 器 （ 如 Deployment 和 StatefulSet） 在 进 行 滚 动 升 级 时 不 受 PDB 的 限 制 — — 在 应 用 程 序 更 新 期 间 的 故 障 处 理 是 在 控 制 器 的 规 格 （ spec） 中 配 置 （ 了 解 < a href = "https://kubernetes.io/docs/concepts/cluster-administration/manage-deployment/#updating-your-application-without-a-service-outage" target = "_blank" > 更 新 Deployment< / a > ） 。 < / p >
2019-03-21 11:23:58 +08:00
< p > 使 用 驱 逐 API 驱 逐 pod 时 ， pod 会 被 优 雅 地 终 止 （ 请 参 阅 PodSpec 中 的 < code > terminationGracePeriodSeconds< / code > ） 。 < / p >

< h2 id = "pdb-示例" > PDB 示 例 < / h2 >
< p > 假 设 集 群 有 3个 节 点 ， < code > node-1< / code > 到 < code > node-3< / code > 。 集 群 中 运 行 了 一 些 应 用 ， 其 中 一 个 应 用 有 3个 副 本 ， 分 别 是 < code > pod-a< / code > 、 < code > pod-b< / code > 和 < code > pod-c< / code > 。 另 外 ， 还 有 一 个 与 它 相 关 的 不 具 有 PDB 的 pod， 我 们 称 为 之 为 < code > pod-x< / code > 。 最 初 ， 所 有 Pod 的 分 布 如 下 ： < / p >

< p > 所 有 的 3个 pod 都 是 Deployment 中 的 一 部 分 ， 并 且 它 们 共 同 拥 有 一 个 PDB， 要 求 至 少 有 3个 pod 中 的 2个 始 终 处 于 可 用 状 态 。 < / p >
< p > 例 如 ， 假 设 集 群 管 理 员 想 要 重 启 系 统 ， 升 级 内 核 版 本 来 修 复 内 核 中 的 错 误 。 集 群 管 理 员 首 先 使 用 < code > kubectl drain< / code > 命 令 尝 试 排 除 < code > node-1< / code > 。 该 工 具 试 图 驱 逐 < code > pod-a< / code > 和 < code > pod-x< / code > 。 这 立 即 成 功 。 两 个 Pod 同 时 进 入 终 止 状 态 。 这 时 的 集 群 处 于 这 种 状 态 ： < / p >

< p > Deployment 注 意 到 其 中 有 一 个 pod 处 于 正 在 终 止 ， 因 此 会 创 建 了 一 个 < code > pod-d< / code > 来 替 换 。 由 于 < code > node-1< / code > 被 封 锁 （ cordon） ， 它 落 在 另 一 个 节 点 上 。 同 时 其 它 控 制 器 也 创 建 了 < code > pod-y< / code > 作 为 < code > pod-x< / code > 的 替 代 品 。 < / p >
< p > （ 注 意 ： 对 于 < code > StatefulSet< / code > ， < code > pod-a< / code > 将 被 称 为 < code > pod-1< / code > ， 需 要 在 替 换 之 前 完 全 终 止 ， 替 代 它 的 也 称 为 < code > pod-1< / code > ， 但 是 具 有 不 同 的 UID， 可 以 创 建 。 否 则 ， 示 例 也 适 用 于 StatefulSet。 ） < / p >

< p > Deployment 将 创 建 一 个 名 为 < code > pod-e< / code > 的 < code > pod-b< / code > 的 替 代 品 。 但 是 ， 集 群 中 没 有 足 够 的 资 源 来 安 排 < code > pod-e< / code > 。 那 么 ， drain 命 令 就 会 被 阻 塞 。 集 群 最 终 可 能 是 这 种 状 态 ： < / p >
