< p > 当 你 使 用 kuberentes的 时 候 ， 有 没 有 遇 到 过 Pod在 启 动 后 一 会 就 挂 掉 然 后 又 重 新 启 动 这 样 的 恶 性 循 环 ？ 你 有 没 有 想 过 kubernetes是 如 何 检 测 pod是 否 还 存 活 ？ 虽 然 容 器 已 经 启 动 ， 但 是 kubernetes如 何 知 道 容 器 的 进 程 是 否 准 备 好 对 外 提 供 服 务 了 呢 ？ 让 我 们 通 过 kuberentes官 网 的 这 篇 文 章 < a href = "https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-probes/" target = "_blank" > Configure Liveness and Readiness Probes< / a > ， 来 一 探 究 竟 。 < / p >
< p > 本 文 将 向 展 示 如 何 配 置 容 器 的 存 活 和 可 读 性 探 针 。 < / p >
< p > Kubelet使 用 liveness probe（ 存 活 探 针 ） 来 确 定 何 时 重 启 容 器 。 例 如 ， 当 应 用 程 序 处 于 运 行 状 态 但 无 法 做 进 一 步 操 作 ， liveness探 针 将 捕 获 到 deadlock， 重 启 处 于 该 状 态 下 的 容 器 ， 使 应 用 程 序 在 存 在 bug的 情 况 下 依 然 能 够 继 续 运 行 下 去 （ 谁 的 程 序 还 没 几 个 bug呢 ） 。 < / p >
< p > Kubelet使 用 readiness probe（ 就 绪 探 针 ） 来 确 定 容 器 是 否 已 经 就 绪 可 以 接 受 流 量 。 只 有 当 Pod中 的 容 器 都 处 于 就 绪 状 态 时 kubelet才 会 认 定 该 Pod处 于 就 绪 状 态 。 该 信 号 的 作 用 是 控 制 哪 些 Pod应 该 作 为 service的 后 端 。 如 果 Pod处 于 非 就 绪 状 态 ， 那 么 它 们 将 会 被 从 service的 load balancer中 移 除 。 < / p >
< h2 id = "定义-liveness命令" > 定 义 liveness命 令 < / h2 >
< p > 许 多 长 时 间 运 行 的 应 用 程 序 最 终 会 转 换 到 broken状 态 ， 除 非 重 新 启 动 ， 否 则 无 法 恢 复 。 Kubernetes提 供 了 liveness probe来 检 测 和 补 救 这 种 情 况 。 < / p >

< p > 如 您 所 见 ， TCP检 查 的 配 置 与 HTTP检 查 非 常 相 似 。 此 示 例 同 时 使 用 了 readiness和 liveness probe。 容 器 启 动 后 5秒 钟 ， kubelet将 发 送 第 一 个 readiness probe。 这 将 尝 试 连 接 到 端 口 8080上 的 goproxy容 器 。 如 果 探 测 成 功 ， 则 该 pod将 被 标 记 为 就 绪 。 Kubelet将 每 隔 10秒 钟 执 行 一 次 该 检 查 。 < / p >
< p > 除 了 readiness probe之 外 ， 该 配 置 还 包 括 liveness probe。 容 器 启 动 15秒 后 ， kubelet将 运 行 第 一 个 liveness probe。 就 像 readiness probe一 样 ， 这 将 尝 试 连 接 到 goproxy容 器 上 的 8080端 口 。 如 果 liveness probe失 败 ， 容 器 将 重 新 启 动 。 < / p >
< h2 id = "使用命名的端口" > 使 用 命 名 的 端 口 < / h2 >
< p > 可 以 使 用 命 名 的 ContainerPort作 为 HTTP或 TCP liveness检 查 ： < / p >
< pre > < code class = "lang-yaml" > < span class = "hljs-attr" > ports:< / span >
< span class = "hljs-attr" > - name:< / span > liveness-port
< span class = "hljs-attr" > containerPort:< / span > < span class = "hljs-number" > 8080< / span >

< span class = "hljs-attr" > port:< / span > liveness-port
< / code > < / pre >
< h2 id = "定义readiness探针" > 定 义 readiness探 针 < / h2 >
< p > 有 时 ， 应 用 程 序 暂 时 无 法 对 外 部 流 量 提 供 服 务 。 例 如 ， 应 用 程 序 可 能 需 要 在 启 动 期 间 加 载 大 量 数 据 或 配 置 文 件 。 在 这 种 情 况 下 ， 你 不 想 杀 死 应 用 程 序 ， 但 你 也 不 想 发 送 请 求 。 Kubernetes提 供 了 readiness probe来 检 测 和 减 轻 这 些 情 况 。 Pod中 的 容 器 可 以 报 告 自 己 还 没 有 准 备 ， 不 能 处 理 Kubernetes服 务 发 送 过 来 的 流 量 。 < / p >
< p > Readiness probe的 配 置 跟 liveness probe很 像 。 唯 一 的 不 同 是 使 用 < code > readinessProbe< / code > 而 不 是 < code > livenessProbe< / code > 。 < / p >
< pre > < code class = "lang-yaml" > < span class = "hljs-attr" > readinessProbe:< / span >
< span class = "hljs-attr" > exec:< / span >

< span class = "hljs-attr" > periodSeconds:< / span > < span class = "hljs-number" > 5< / span >
< / code > < / pre >
< p > Readiness probe的 HTTP和 TCP的 探 测 器 配 置 跟 liveness probe一 样 。 < / p >
< p > Readiness和 livenss probe可 以 并 行 用 于 同 一 容 器 。 使 用 两 者 可 以 确 保 流 量 无 法 到 达 未 准 备 好 的 容 器 ， 并 且 容 器 在 失 败 时 重 新 启 动 。 < / p >
