< p > 该 特 性 在 1.6 版 本 已 经 推 出 beta 版 本 。 Init 容 器 可 以 在 PodSpec 中 同 应 用 程 序 的 < code > containers< / code > 数 组 一 起 来 指 定 。 beta 注 解 的 值 将 仍 需 保 留 ， 并 覆 盖 PodSpec 字 段 值 。 < / p >
2017-08-31 23:28:33 +08:00
< p > 本 文 讲 解 Init 容 器 的 基 本 概 念 ， 它 是 一 种 专 用 的 容 器 ， 在 应 用 程 序 容 器 启 动 之 前 运 行 ， 并 包 括 一 些 应 用 镜 像 中 不 存 在 的 实 用 工 具 和 安 装 脚 本 。 < / p >
< h2 id = "理解-init-容器" > 理 解 Init 容 器 < / h2 >
< p > < a href = "https://kubernetes.io/docs/concepts/abstractions/pod/" target = "_blank" > Pod< / a > 能 够 具 有 多 个 容 器 ， 应 用 运 行 在 容 器 里 面 ， 但 是 它 也 可 能 有 一 个 或 多 个 先 于 应 用 容 器 启 动 的 Init 容 器 。 < / p >
< p > Init 容 器 与 普 通 的 容 器 非 常 像 ， 除 了 如 下 两 点 ： < / p >
< ul >
< li > Init 容 器 总 是 运 行 到 成 功 完 成 为 止 。 < / li >
< li > 每 个 Init 容 器 都 必 须 在 下 一 个 Init 容 器 启 动 之 前 成 功 完 成 。 < / li >
< / ul >
< p > 如 果 Pod 的 Init 容 器 失 败 ， Kubernetes 会 不 断 地 重 启 该 Pod， 直 到 Init 容 器 成 功 为 止 。 然 而 ， 如 果 Pod 对 应 的 < code > restartPolicy< / code > 为 Never， 它 不 会 重 新 启 动 。 < / p >
< p > 指 定 容 器 为 Init 容 器 ， 在 PodSpec 中 添 加 < code > initContainers< / code > 字 段 ， 以 < a href = "https://kubernetes.io/docs/api-reference/v1.6/#container-v1-core" target = "_blank" > v1.Container< / a > 类 型 对 象 的 JSON 数 组 的 形 式 ， 还 有 app 的 < code > containers< / code > 数 组 。 Init 容 器 的 状 态 在 < code > status.initContainerStatuses< / code > 字 段 中 以 容 器 状 态 数 组 的 格 式 返 回 （ 类 似 < code > status.containerStatuses< / code > 字 段 ） 。 < / p >
< h3 id = "与普通容器的不同之处" > 与 普 通 容 器 的 不 同 之 处 < / h3 >
< p > Init 容 器 支 持 应 用 容 器 的 全 部 字 段 和 特 性 ， 包 括 资 源 限 制 、 数 据 卷 和 安 全 设 置 。 然 而 ， Init 容 器 对 资 源 请 求 和 限 制 的 处 理 稍 有 不 同 ， 在 下 面 < a href = "https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources" target = "_blank" > 资 源 < / a > 处 有 说 明 。 而 且 Init 容 器 不 支 持 Readiness Probe， 因 为 它 们 必 须 在 Pod 就 绪 之 前 运 行 完 成 。 < / p >
< p > 如 果 为 一 个 Pod 指 定 了 多 个 Init 容 器 ， 那 些 容 器 会 按 顺 序 一 次 运 行 一 个 。 每 个 Init 容 器 必 须 运 行 成 功 ， 下 一 个 才 能 够 运 行 。 当 所 有 的 Init 容 器 运 行 完 成 时 ， Kubernetes 初 始 化 Pod 并 像 平 常 一 样 运 行 应 用 容 器 。 < / p >
< h2 id = "init-容器能做什么？" > Init 容 器 能 做 什 么 ？ < / h2 >
< p > 因 为 Init 容 器 具 有 与 应 用 程 序 容 器 分 离 的 单 独 镜 像 ， 所 以 它 们 的 启 动 相 关 代 码 具 有 如 下 优 势 ： < / p >
< ul >
< li > 它 们 可 以 包 含 并 运 行 实 用 工 具 ， 但 是 出 于 安 全 考 虑 ， 是 不 建 议 在 应 用 程 序 容 器 镜 像 中 包 含 这 些 实 用 工 具 的 。 < / li >
< li > 它 们 可 以 包 含 使 用 工 具 和 定 制 化 代 码 来 安 装 ， 但 是 不 能 出 现 在 应 用 程 序 镜 像 中 。 例 如 ， 创 建 镜 像 没 必 要 < code > FROM< / code > 另 一 个 镜 像 ， 只 需 要 在 安 装 过 程 中 使 用 类 似 < code > sed< / code > 、 < code > awk< / code > 、 < code > python< / code > 或 < code > dig< / code > 这 样 的 工 具 。 < / li >
< li > 应 用 程 序 镜 像 可 以 分 离 出 创 建 和 部 署 的 角 色 ， 而 没 有 必 要 联 合 它 们 构 建 一 个 单 独 的 镜 像 。 < / li >
< li > Init 容 器 使 用 Linux Namespace， 所 以 相 对 应 用 程 序 容 器 来 说 具 有 不 同 的 文 件 系 统 视 图 。 因 此 ， 它 们 能 够 具 有 访 问 Secret 的 权 限 ， 而 应 用 程 序 容 器 则 不 能 。 < / li >
< li > 它 们 必 须 在 应 用 程 序 容 器 启 动 之 前 运 行 完 成 ， 而 应 用 程 序 容 器 是 并 行 运 行 的 ， 所 以 Init 容 器 能 够 提 供 了 一 种 简 单 的 阻 塞 或 延 迟 应 用 容 器 的 启 动 的 方 法 ， 直 到 满 足 了 一 组 先 决 条 件 。 < / li >
< / ul >
< h3 id = "示例" > 示 例 < / h3 >
< p > 下 面 是 一 些 如 何 使 用 Init 容 器 的 想 法 ： < / p >
< ul >
< li > < p > 等 待 一 个 Service 创 建 完 成 ， 通 过 类 似 如 下 shell 命 令 ： < / p >
< pre > < code > for i in {1..100}; do sleep 1; if dig myservice; then exit 0; fi; exit 1
< / code > < / pre > < / li >
< li > < p > 将 Pod 注 册 到 远 程 服 务 器 ， 通 过 在 命 令 中 调 用 API， 类 似 如 下 ： < / p >
< pre > < code > curl -X POST http://$MANAGEMENT_SERVICE_HOST:$MANAGEMENT_SERVICE_PORT/register -d ' instance=$(< POD_NAME> )& ip=$(< POD_IP> )'
< / code > < / pre > < / li >
< li > < p > 在 启 动 应 用 容 器 之 前 等 一 段 时 间 ， 使 用 类 似 < code > sleep 60< / code > 的 命 令 。 < / p >
< / li >
< li > < p > 克 隆 Git 仓 库 到 数 据 卷 。 < / p >
< / li >
< li > < p > 将 配 置 值 放 到 配 置 文 件 中 ， 运 行 模 板 工 具 为 主 应 用 容 器 动 态 地 生 成 配 置 文 件 。 例 如 ， 在 配 置 文 件 中 存 放 POD_IP 值 ， 并 使 用 Jinja 生 成 主 应 用 配 置 文 件 。 < / p >
< / li >
< / ul >
< p > 更 多 详 细 用 法 示 例 ， 可 以 在 < a href = "https://kubernetes.io/docs/concepts/abstractions/controllers/statefulsets/" target = "_blank" > StatefulSet 文 档 < / a > 和 < a href = "https://kubernetes.io/docs/user-guide/production-pods.md#handling-initialization" target = "_blank" > 生 产 环 境 Pod 指 南 < / a > 中 找 到 。 < / p >
< h3 id = "使用-init-容器" > 使 用 Init 容 器 < / h3 >
< p > 下 面 是 Kubernetes 1.5 版 本 yaml 文 件 ， 展 示 了 一 个 具 有 2 个 Init 容 器 的 简 单 Pod。 第 一 个 等 待 < code > myservice< / code > 启 动 ， 第 二 个 等 待 < code > mydb< / code > 启 动 。 一 旦 这 两 个 Service 都 启 动 完 成 ， Pod 将 开 始 启 动 。 < / p >

< p > 1.5 版 本 的 语 法 在 1.6 版 本 仍 然 可 以 使 用 ， 但 是 我 们 推 荐 使 用 1.6 版 本 的 新 语 法 。 在 Kubernetes 1.6 版 本 中 ， Init 容 器 在 API 中 新 建 了 一 个 字 段 。 虽 然 期 望 使 用 beta 版 本 的 annotation， 但 在 未 来 发 行 版 将 会 被 废 弃 掉 。 < / p >

< p > 这 个 例 子 非 常 简 单 ， 但 是 应 该 能 够 为 我 们 创 建 自 己 的 Init 容 器 提 供 一 些 启 发 。 < / p >
< h2 id = "具体行为" > 具 体 行 为 < / h2 >
< p > 在 Pod 启 动 过 程 中 ， Init 容 器 会 按 顺 序 在 网 络 和 数 据 卷 初 始 化 之 后 启 动 。 每 个 容 器 必 须 在 下 一 个 容 器 启 动 之 前 成 功 退 出 。 如 果 由 于 运 行 时 或 失 败 退 出 ， 导 致 容 器 启 动 失 败 ， 它 会 根 据 Pod 的 < code > restartPolicy< / code > 指 定 的 策 略 进 行 重 试 。 然 而 ， 如 果 Pod 的 < code > restartPolicy< / code > 设 置 为 Always， Init 容 器 失 败 时 会 使 用 < code > RestartPolicy< / code > 策 略 。 < / p >
< p > 在 所 有 的 Init 容 器 没 有 成 功 之 前 ， Pod 将 不 会 变 成 < code > Ready< / code > 状 态 。 Init 容 器 的 端 口 将 不 会 在 Service 中 进 行 聚 集 。 正 在 初 始 化 中 的 Pod 处 于 < code > Pending< / code > 状 态 ， 但 应 该 会 将 条 件 < code > Initializing< / code > 设 置 为 true。 < / p >
< p > 如 果 Pod < a href = "https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#pod-restart-reasons" target = "_blank" > 重 启 < / a > ， 所 有 Init 容 器 必 须 重 新 执 行 。 < / p >
< p > 对 Init 容 器 spec 的 修 改 ， 被 限 制 在 容 器 image 字 段 中 。 更 改 Init 容 器 的 image 字 段 ， 等 价 于 重 启 该 Pod。 < / p >
< p > 因 为 Init 容 器 可 能 会 被 重 启 、 重 试 或 者 重 新 执 行 ， 所 以 Init 容 器 的 代 码 应 该 是 幂 等 的 。 特 别 地 ， 被 写 到 < code > EmptyDirs< / code > 中 文 件 的 代 码 ， 应 该 对 输 出 文 件 可 能 已 经 存 在 做 好 准 备 。 < / p >
< p > Init 容 器 具 有 应 用 容 器 的 所 有 字 段 。 除 了 < code > readinessProbe< / code > ， 因 为 Init 容 器 无 法 定 义 不 同 于 完 成 （ completion） 的 就 绪 （ readiness） 的 之 外 的 其 他 状 态 。 这 会 在 验 证 过 程 中 强 制 执 行 。 < / p >
< p > 在 Pod 上 使 用 < code > activeDeadlineSeconds< / code > ， 在 容 器 上 使 用 < code > livenessProbe< / code > ， 这 样 能 够 避 免 Init 容 器 一 直 失 败 。 这 就 为 Init 容 器 活 跃 设 置 了 一 个 期 限 。 < / p >
< p > 在 Pod 中 的 每 个 app 和 Init 容 器 的 名 称 必 须 唯 一 ； 与 任 何 其 它 容 器 共 享 同 一 个 名 称 ， 会 在 验 证 时 抛 出 错 误 。 < / p >
< h3 id = "资源" > 资 源 < / h3 >
< p > 为 Init 容 器 指 定 顺 序 和 执 行 逻 辑 ， 下 面 对 资 源 使 用 的 规 则 将 被 应 用 ： < / p >
< ul >
< li > 在 所 有 Init 容 器 上 定 义 的 ， 任 何 特 殊 资 源 请 求 或 限 制 的 最 大 值 ， 是 < em > 有 效 初 始 请 求 /限 制 < / em > < / li >
< li > < p > Pod 对 资 源 的 有 效 请 求 /限 制 要 高 于 ： < / p >
< ul >
< li > 所 有 应 用 容 器 对 某 个 资 源 的 请 求 /限 制 之 和 < / li >
< li > 对 某 个 资 源 的 有 效 初 始 请 求 /限 制 < / li >
< / ul >
< / li >
< li > < p > 基 于 有 效 请 求 /限 制 完 成 调 度 ， 这 意 味 着 Init 容 器 能 够 为 初 始 化 预 留 资 源 ， 这 些 资 源 在 Pod 生 命 周 期 过 程 中 并 没 有 被 使 用 。 < / p >
< / li >
< li > < p > Pod 的 < em > 有 效 QoS 层 < / em > ， 是 Init 容 器 和 应 用 容 器 相 同 的 QoS 层 。 < / p >
< / li >
< / ul >
< p > 基 于 有 效 Pod 请 求 和 限 制 来 应 用 配 额 和 限 制 。 Pod 级 别 的 cgroups 是 基 于 有 效 Pod 请 求 和 限 制 ， 和 调 度 器 相 同 。 < / p >
< h3 id = "pod-重启的原因" > Pod 重 启 的 原 因 < / h3 >
< p > Pod 能 够 重 启 ， 会 导 致 Init 容 器 重 新 执 行 ， 主 要 有 如 下 几 个 原 因 ： < / p >
< ul >
< li > 用 户 更 新 PodSpec 导 致 Init 容 器 镜 像 发 生 改 变 。 应 用 容 器 镜 像 的 变 更 只 会 重 启 应 用 容 器 。 < / li >
< li > Pod 基 础 设 施 容 器 被 重 启 。 这 不 多 见 ， 但 某 些 具 有 root 权 限 可 访 问 Node 的 人 可 能 会 这 样 做 。 < / li >
2017-11-22 18:43:03 +08:00
< li > 当 < code > restartPolicy< / code > 设 置 为 Always， Pod 中 所 有 容 器 会 终 止 ， 强 制 重 启 ， 由 于 垃 圾 收 集 导 致 Init 容 器 完 整 的 记 录 丢 失 。 < / li >
