< h2 id = "sidecar-注入及流量劫持步骤概述" > Sidecar 注 入 及 流 量 劫 持 步 骤 概 述 < / h2 >
< p > 下 面 是 从 Sidecar 注 入 、 Pod 启 动 到 Sidecar proxy 拦 截 流 量 及 Envoy 处 理 路 由 的 步 骤 概 览 。 < / p >
< p > < strong > 1.< / strong > Kubernetes 通 过 Admission Controller 自 动 注 入 ， 或 者 用 户 使 用 < code > istioctl< / code > 命 令 手 动 注 入 sidecar 容 器 。 < / p >
< p > < strong > 2.< / strong > 应 用 YAML 配 置 部 署 应 用 ， 此 时 Kubernetes API server 接 收 到 的 服 务 创 建 配 置 文 件 中 已 经 包 含 了 Init 容 器 及 sidecar proxy。 < / p >
< p > < strong > 3.< / strong > 在 sidecar proxy 容 器 和 应 用 容 器 启 动 之 前 ， 首 先 运 行 Init 容 器 ， Init 容 器 用 于 设 置 iptables（ Istio 中 默 认 的 流 量 拦 截 方 式 ， 还 可 以 使 用 BPF、 IPVS 等 方 式 ） 将 进 入 pod 的 流 量 劫 持 到 Envoy sidecar proxy。 所 有 TCP 流 量 （ Envoy 目 前 只 支 持 TCP 流 量 ） 将 被 sidecar 劫 持 ， 其 他 协 议 的 流 量 将 按 原 来 的 目 的 地 请 求 。 < / p >
< p > < strong > 4.< / strong > 启 动 Pod 中 的 Envoy sidecar proxy 和 应 用 程 序 容 器 。 这 一 步 的 过 程 请 参 考 < a href = "https://zhaohuabing.com/post/2018-09-25-istio-traffic-management-impl-intro/#%E9%80%9A%E8%BF%87%E7%AE%A1%E7%90%86%E6%8E%A5%E5%8F%A3%E8%8E%B7%E5%8F%96%E5%AE%8C%E6%95%B4%E9%85%8D%E7%BD%AE" target = "_blank" > 通 过 管 理 接 口 获 取 完 整 配 置 < / a > 。 < / p >
< blockquote >
< p > < strong > Sidecar proxy 与 应 用 容 器 的 启 动 顺 序 问 题 < / strong > < / p >
< p > 启 动 sidecar proxy 和 应 用 容 器 ， 究 竟 哪 个 容 器 先 启 动 呢 ？ 正 常 情 况 是 Envoy Sidecar 和 应 用 程 序 容 器 全 部 启 动 完 成 后 再 开 始 接 收 流 量 请 求 。 但 是 我 们 无 法 预 料 哪 个 容 器 会 先 启 动 ， 那 么 容 器 启 动 顺 序 是 否 会 对 Envoy 劫 持 流 量 有 影 响 呢 ？ 答 案 是 肯 定 的 ， 不 过 分 为 以 下 两 种 情 况 。 < / p >
< p > < strong > 情 况 1： 应 用 容 器 先 启 动 ， 而 sidecar proxy 仍 未 就 绪 < / strong > < / p >
< p > 这 种 情 况 下 ， 流 量 被 iptables 转 移 到 15001 端 口 ， 而 Pod 中 没 有 监 听 该 端 口 ， TCP 链 接 就 无 法 建 立 ， 请 求 失 败 。 < / p >
< p > < strong > 情 况 2： Sidecar 先 启 动 ， 请 求 到 达 而 应 用 程 序 仍 未 就 绪 < / strong > < / p >
< p > 这 种 情 况 下 请 求 也 肯 定 会 失 败 ， 至 于 是 在 哪 一 步 开 始 失 败 的 ， 留 给 读 者 来 思 考 。 < / p >
< / blockquote >
< p > < strong > 问 题 < / strong > ： 如 果 为 sidecar proxy 和 应 用 程 序 容 器 添 加 < a href = "https://jimmysong.io/kubernetes-handbook/guide/configure-liveness-readiness-probes.html" target = "_blank" > 就 绪 和 存 活 探 针 < / a > 是 否 可 以 解 决 该 问 题 呢 ？ < / p >
< p > < strong > 5.< / strong > 不 论 是 进 入 还 是 从 Pod 发 出 的 TCP 请 求 都 会 被 iptables 劫 持 ， inbound 流 量 被 劫 持 后 经 Inbound Handler 处 理 后 转 交 给 应 用 程 序 容 器 处 理 ， outbound 流 量 被 iptables 劫 持 后 转 交 给 Outbound Handler 处 理 ， 并 确 定 转 发 的 upstream 和 Endpoint。 < / p >
< p > < strong > 6.< / strong > Sidecar proxy 请 求 Pilot 使 用 xDS 协 议 同 步 Envoy 配 置 ， 其 中 包 括 LDS、 EDS、 CDS 等 ， 不 过 为 了 保 证 更 新 的 顺 序 ， Envoy 会 直 接 使 用 ADS 向 Pilot 请 求 配 置 更 新 。 < / p >
