< p > Pod是 kubernetes中 可 以 创 建 的 最 小 部 署 单 元 。 < / p >
< p > V1 core版 本 的 Pod的 配 置 模 板 见 < a href = "../manifests/template/pod-v1-template.yaml" > Pod template< / a > 。 < / p >
< h2 id = "什么是pod?" > 什 么 是 Pod? < / h2 >
< p > Pod就 像 是 豌 豆 荚 一 样 , 它 由 一 个 或 者 多 个 容 器 组 成 ( 例 如 Docker容 器 ) , 它 们 共 享 容 器 存 储 、 网 络 和 容 器 运 行 配 置 项 。 Pod中 的 容 器 总 是 被 同 时 调 度 , 有 共 同 的 运 行 环 境 。 你 可 以 把 单 个 Pod想 象 成 是 运 行 独 立 应 用 的 “ 逻 辑 主 机 ” — — 其 中 运 行 着 一 个 或 者 多 个 紧 密 耦 合 的 应 用 容 器 — — 在 有 容 器 之 前 , 这 些 应 用 都 是 运 行 在 几 个 相 同 的 物 理 机 或 者 虚 拟 机 上 。 < / p >
2017-11-22 18:43:03 +08:00
< p > 尽 管 kubernetes支 持 多 种 容 器 运 行 时 , 但 是 Docker依 然 是 最 常 用 的 运 行 时 环 境 , 我 们 可 以 使 用 Docker的 术 语 和 规 则 来 定 义 Pod。 < / p >
< p > Pod中 共 享 的 环 境 包 括 Linux的 namespace, cgroup和 其 他 可 能 的 隔 绝 环 境 , 这 一 点 跟 Docker容 器 一 致 。 在 Pod的 环 境 中 , 每 个 容 器 中 可 能 还 有 更 小 的 子 隔 离 环 境 。 < / p >
2017-08-21 17:44:43 +08:00
< p > Pod中 的 容 器 共 享 IP地 址 和 端 口 号 , 它 们 之 间 可 以 通 过 < code > localhost< / code > 互 相 发 现 。 它 们 之 间 可 以 通 过 进 程 间 通 信 , 例 如 < a href = "https://en.wikipedia.org/wiki/UNIX_System_V" target = "_blank" > SystemV< / a > 信 号 或 者 POSIX共 享 内 存 。 不 同 Pod之 间 的 容 器 具 有 不 同 的 IP地 址 , 不 能 直 接 通 过 IPC通 信 。 < / p >
< p > Pod中 的 容 器 也 有 访 问 共 享 volume的 权 限 , 这 些 volume会 被 定 义 成 pod的 一 部 分 并 挂 载 到 应 用 容 器 的 文 件 系 统 中 。 < / p >
2017-11-22 18:43:03 +08:00
< p > 根 据 Docker的 结 构 , Pod中 的 容 器 共 享 namespace和 volume, 不 支 持 共 享 PID的 namespace。 < / p >
< p > 就 像 每 个 应 用 容 器 , pod被 认 为 是 临 时 ( 非 持 久 的 ) 实 体 。 在 Pod的 生 命 周 期 中 讨 论 过 , pod被 创 建 后 , 被 分 配 一 个 唯 一 的 ID( UID) , 调 度 到 节 点 上 , 并 一 致 维 持 期 望 的 状 态 直 到 被 终 结 ( 根 据 重 启 策 略 ) 或 者 被 删 除 。 如 果 node死 掉 了 , 分 配 到 了 这 个 node上 的 pod, 在 经 过 一 个 超 时 时 间 后 会 被 重 新 调 度 到 其 他 node节 点 上 。 一 个 给 定 的 pod( 如 UID定 义 的 ) 不 会 被 “ 重 新 调 度 ” 到 新 的 节 点 上 , 而 是 被 一 个 同 样 的 pod取 代 , 如 果 期 望 的 话 甚 至 可 以 是 相 同 的 名 字 , 但 是 会 有 一 个 新 的 UID( 查 看 replication controller获 取 详 情 ) 。 ( 未 来 , 一 个 更 高 级 别 的 API将 支 持 pod迁 移 ) 。 < / p >
2017-08-21 17:44:43 +08:00
< p > Volume跟 pod有 相 同 的 生 命 周 期 ( 当 其 UID存 在 的 时 候 ) 。 当 Pod因 为 某 种 原 因 被 删 除 或 者 被 新 创 建 的 相 同 的 Pod取 代 , 它 相 关 的 东 西 ( 例 如 volume) 也 会 被 销 毁 和 再 创 建 一 个 新 的 volume。 < / p >

< p > Pod是 一 个 服 务 的 多 个 进 程 的 聚 合 单 位 , pod提 供 这 种 模 型 能 够 简 化 应 用 部 署 管 理 , 通 过 提 供 一 个 更 高 级 别 的 抽 象 的 方 式 。 Pod作 为 一 个 独 立 的 部 署 单 位 , 支 持 横 向 扩 展 和 复 制 。 共 生 ( 协 同 调 度 ) , 命 运 共 同 体 ( 例 如 被 终 结 ) , 协 同 复 制 , 资 源 共 享 , 依 赖 管 理 , Pod都 会 自 动 的 为 容 器 处 理 这 些 问 题 。 < / p >

< p > Pod中 的 应 用 可 以 共 享 网 络 空 间 ( IP地 址 和 端 口 ) , 因 此 可 以 通 过 < code > localhost< / code > 互 相 发 现 。 因 此 , pod中 的 应 用 必 须 协 调 端 口 占 用 。 每 个 pod都 有 一 个 唯 一 的 IP地 址 , 跟 物 理 机 和 其 他 pod都 处 于 一 个 扁 平 的 网 络 空 间 中 , 它 们 之 间 可 以 直 接 连 通 。 < / p >

< h2 id = "pod的使用" > Pod的 使 用 < / h2 >
< p > Pod也 可 以 用 于 垂 直 应 用 栈 ( 例 如 LAMP) , 这 样 使 用 的 主 要 动 机 是 为 了 支 持 共 同 调 度 和 协 调 管 理 应 用 程 序 , 例 如 : < / p >

< p > 通 常 单 个 pod中 不 会 同 时 运 行 一 个 应 用 的 多 个 实 例 。 < / p >

< p > < strong > 为 什 么 不 直 接 在 一 个 容 器 中 运 行 多 个 应 用 程 序 呢 ? < / strong > < / p >
< ol >
< li > 透 明 。 让 Pod中 的 容 器 对 基 础 设 施 可 见 , 以 便 基 础 设 施 能 够 为 这 些 容 器 提 供 服 务 , 例 如 进 程 管 理 和 资 源 监 控 。 这 可 以 为 用 户 带 来 极 大 的 便 利 。 < / li >
< li > 解 耦 软 件 依 赖 。 每 个 容 器 都 可 以 进 行 版 本 管 理 , 独 立 的 编 译 和 发 布 。 未 来 kubernetes甚 至 可 能 支 持 单 个 容 器 的 在 线 升 级 。 < / li >
< li > 使 用 方 便 。 用 户 不 必 运 行 自 己 的 进 程 管 理 器 , 还 要 担 心 错 误 信 号 传 播 等 。 < / li >
< li > 效 率 。 因 为 由 基 础 架 构 提 供 更 多 的 职 责 , 所 以 容 器 可 以 变 得 更 加 轻 量 级 。 < / li >
< / ol >
< p > < strong > 为 什 么 不 支 持 容 器 的 亲 和 性 的 协 同 调 度 ? < / strong > < / p >
< p > 这 种 方 法 可 以 提 供 容 器 的 协 同 定 位 , 能 够 根 据 容 器 的 亲 和 性 进 行 调 度 , 但 是 无 法 实 现 使 用 pod带 来 的 大 部 分 好 处 , 例 如 资 源 共 享 , IPC, 保 持 状 态 一 致 性 和 简 化 管 理 等 。 < / p >
< h2 id = "pod的持久性(或者说缺乏持久性)" > Pod的 持 久 性 ( 或 者 说 缺 乏 持 久 性 ) < / h2 >
< p > Pod在 设 计 支 持 就 不 是 作 为 持 久 化 实 体 的 。 在 调 度 失 败 、 节 点 故 障 、 缺 少 资 源 或 者 节 点 维 护 的 状 态 下 都 会 死 掉 会 被 驱 逐 。 < / p >
2017-11-21 12:01:09 +08:00
< p > 通 常 , 用 户 不 需 要 手 动 直 接 创 建 Pod, 而 是 应 该 使 用 controller( 例 如 < a href = "deployment.html" > Deployments< / a > ) , 即 使 是 在 创 建 单 个 Pod的 情 况 下 。 Controller可 以 提 供 集 群 级 别 的 自 愈 功 能 、 复 制 和 升 级 管 理 。 < / p >
2017-08-21 17:44:43 +08:00
< p > The use of collective APIs as the primary user-facing primitive is relatively common among cluster scheduling systems, including < a href = "https://research.google.com/pubs/pub43438.html" target = "_blank" > Borg< / a > , < a href = "https://mesosphere.github.io/marathon/docs/rest-api.html" target = "_blank" > Marathon< / a > , < a href = "http://aurora.apache.org/documentation/latest/reference/configuration/#job-schema" target = "_blank" > Aurora< / a > , and < a href = "http://www.slideshare.net/Docker/aravindnarayanan-facebook140613153626phpapp02-37588997" target = "_blank" > Tupperware< / a > .< / p >
< p > Pod is exposed as a primitive in order to facilitate:< / p >
< ul >
< li > scheduler and controller pluggability< / li >
< li > support for pod-level operations without the need to " proxy" them via controller APIs< / li >
< li > decoupling of pod lifetime from controller lifetime, such as for bootstrapping< / li >
< li > decoupling of controllers and services — the endpoint controller just watches pods< / li >
< li > clean composition of Kubelet-level functionality with cluster-level functionality — Kubelet is effectively the " pod controller" < / li >
< li > high-availability applications, which will expect pods to be replaced in advance of their termination and certainly in advance of deletion, such as in the case of planned evictions, image prefetching, or live pod migration < a href = "http://issue.k8s.io/3949" target = "_blank" > #3949< / a > < / li >
< / ul >
< p > < a href = "statefulset.html" > StatefulSet< / a > controller( 目 前 还 是 beta状 态 ) 支 持 有 状 态 的 Pod。 在 1.4版 本 中 被 称 为 PetSet。 在 kubernetes之 前 的 版 本 中 创 建 有 状 态 pod的 最 佳 方 式 是 创 建 一 个 replica为 1的 replication controller。 < / p >
< h2 id = "pod的终止" > Pod的 终 止 < / h2 >
< p > 因 为 Pod作 为 在 集 群 的 节 点 上 运 行 的 进 程 , 所 以 在 不 再 需 要 的 时 候 能 够 优 雅 的 终 止 掉 是 十 分 必 要 的 ( 比 起 使 用 发 送 KILL信 号 这 种 暴 力 的 方 式 ) 。 用 户 需 要 能 够 放 松 删 除 请 求 , 并 且 知 道 它 们 何 时 会 被 终 止 , 是 否 被 正 确 的 删 除 。 用 户 想 终 止 程 序 时 发 送 删 除 pod的 请 求 , 在 pod可 以 被 强 制 删 除 前 会 有 一 个 优 雅 删 除 的 时 间 , 会 发 送 一 个 TERM请 求 到 每 个 容 器 的 主 进 程 。 一 旦 超 时 , 将 向 主 进 程 发 送 KILL信 号 并 从 API server中 删 除 。 如 果 kubelet或 者 container manager在 等 待 进 程 终 止 的 过 程 中 重 启 , 在 重 启 后 仍 然 会 重 试 完 整 的 优 雅 删 除 阶 段 。 < / p >
< p > 示 例 流 程 如 下 : < / p >
< ol >
< li > 用 户 发 送 删 除 pod的 命 令 , 默 认 优 雅 删 除 时 期 是 30秒 ; < / li >
< li > 在 Pod超 过 该 优 雅 删 除 期 限 后 API server就 会 更 新 Pod的 状 态 为 “ dead” ; < / li >
< li > 在 客 户 端 命 令 行 上 显 示 的 Pod状 态 为 “ terminating” ; < / li >
< li > 跟 第 三 步 同 时 , 当 kubelet发 现 pod被 标 记 为 “ terminating” 状 态 时 , 开 始 停 止 pod进 程 : < ol >
< li > 如 果 在 pod中 定 义 了 preStop hook, 在 停 止 pod前 会 被 调 用 。 如 果 在 优 雅 删 除 期 限 过 期 后 , preStop hook依 然 在 运 行 , 第 二 步 会 再 增 加 2秒 的 优 雅 时 间 ; < / li >
< li > 向 Pod中 的 进 程 发 送 TERM信 号 ; < / li >
< / ol >
< / li >
< li > 跟 第 三 步 同 时 , 该 Pod将 从 该 service的 端 点 列 表 中 删 除 , 不 再 是 replication controller的 一 部 分 。 关 闭 的 慢 的 pod将 继 续 处 理 load balancer转 发 的 流 量 ; < / li >
< li > 过 了 优 雅 周 期 后 , 将 向 Pod中 依 然 运 行 的 进 程 发 送 SIGKILL信 号 而 杀 掉 进 程 。 < / li >
< li > Kublete会 在 API server中 完 成 Pod的 的 删 除 , 通 过 将 优 雅 周 期 设 置 为 0( 立 即 删 除 ) 。 Pod在 API中 消 失 , 并 且 在 客 户 端 也 不 可 见 。 < / li >
< / ol >
< p > 删 除 优 雅 周 期 默 认 是 30秒 。 < code > kubectl delete< / code > 命 令 支 持 < code > — grace-period=< seconds> < / code > 选 项 , 允 许 用 户 设 置 自 己 的 优 雅 周 期 时 间 。 如 果 设 置 为 0将 强 制 删 除 pod。 在 kubectl> =1.5版 本 的 命 令 中 , 你 必 须 同 时 使 用 < code > --force< / code > 和 < code > --grace-period=0< / code > 来 强 制 删 除 pod。 < / p >
< h3 id = "强制删除pod" > 强 制 删 除 Pod< / h3 >
< p > Pod的 强 制 删 除 是 通 过 在 集 群 和 etcd中 将 其 定 义 为 删 除 状 态 。 当 执 行 强 制 删 除 命 令 时 , API server不 会 等 待 该 pod所 运 行 在 节 点 上 的 kubelet确 认 , 就 会 立 即 将 该 pod从 API server中 移 除 , 这 时 就 可 以 创 建 跟 原 pod同 名 的 pod了 。 这 时 , 在 节 点 上 的 pod会 被 立 即 设 置 为 terminating状 态 , 不 过 在 被 强 制 删 除 之 前 依 然 有 一 小 段 优 雅 删 除 周 期 。 < / p >
< p > 强 制 删 除 对 于 某 些 pod具 有 潜 在 危 险 性 , 请 谨 慎 使 用 。 使 用 StatefulSet pod的 情 况 下 , 请 参 考 删 除 StatefulSet中 的 pod文 章 。 < / p >

2017-11-22 18:43:03 +08:00
< p > 从 kubernetes1.1版 本 开 始 , pod中 的 容 器 就 可 以 开 启 previleged模 式 , 在 容 器 定 义 文 件 的 < code > SecurityContext< / code > 下 使 用 < code > privileged< / code > flag。 这 在 使 用 Linux的 网 络 操 作 和 访 问 设 备 的 能 力 时 是 很 用 的 。 同 时 开 启 的 特 权 模 式 的 Pod中 的 容 器 也 可 以 访 问 到 容 器 外 的 进 程 和 应 用 。 在 不 需 要 修 改 和 重 新 编 译 kubelet的 情 况 下 就 可 以 使 用 pod来 开 发 节 点 的 网 络 和 存 储 插 件 。 < / p >
< p > 如 果 master节 点 运 行 的 是 kuberentes1.1或 更 高 版 本 , 而 node节 点 的 版 本 低 于 1.1版 本 , 则 API server将 也 可 以 接 受 新 的 特 权 模 式 的 pod, 但 是 无 法 启 动 , pod将 处 于 pending状 态 。 < / p >
2017-08-21 17:44:43 +08:00
< p > 执 行 < code > kubectl describe pod FooPodName< / code > , 可 以 看 到 为 什 么 pod处 于 pending状 态 。 输 出 的 event列 表 中 将 显 示 :
< code > Error validating pod " FooPodName" ." FooPodNamespace" from api, ignoring: spec.containers[0].securityContext.privileged: forbidden ' < *> (0xc2089d3248)true' < / code > < / p >
< p > 如 果 master节 点 的 版 本 低 于 1.1, 无 法 创 建 特 权 模 式 的 pod。 如 果 你 仍 然 试 图 去 创 建 的 话 , 你 得 到 如 下 错 误 : < / p >
