< p > Cilium是 一 个 纯 开 源 软 件 ， 没 有 哪 家 公 司 提 供 商 业 化 支 持 ， 也 不 是 由 某 一 公 司 开 源 ， 该 软 件 用 于 透 明 地 保 护 使 用 Linux容 器 管 理 平 台 （ 如 Docker和 Kubernetes） 部 署 的 应 用 程 序 服 务 之 间 的 网 络 连 接 。 < / p >
< p > Cilium的 基 础 是 一 种 名 为 BPF的 新 Linux内 核 技 术 ， 它 可 以 在 Linux本 身 动 态 插 入 强 大 的 安 全 可 见 性 和 控 制 逻 辑 。 由 于 BPF在 Linux内 核 中 运 行 ， 因 此 可 以 应 用 和 更 新 Cilium安 全 策 略 ， 而 无 需 对 应 用 程 序 代 码 或 容 器 配 置 进 行 任 何 更 改 。 < / p >

< p > 基 于 微 服 务 的 应 用 程 序 分 为 小 型 独 立 服 务 ， 这 些 服 务 使 用 < strong > HTTP< / strong > 、 < strong > gRPC< / strong > 、 < strong > Kafka< / strong > 等 轻 量 级 协 议 通 过 API相 互 通 信 。 但 是 ， 现 有 的 Linux网 络 安 全 机 制 （ 例 如 iptables） 仅 在 网 络 和 传 输 层 （ 即 IP地 址 和 端 口 ） 上 运 行 ， 并 且 缺 乏 对 微 服 务 层 的 可 见 性 。 < / p >
< p > Cilium为 Linux容 器 框 架 （ 如 < a href = "https://www.docker.com/" target = "_blank" > < strong > Docker< / strong > < / a > 和 < a href = "https://kubernetes.io/" target = "_blank" > < strong > Kubernetes） < / strong > < / a > 带 来 了 API感 知 网 络 安 全 过 滤 。 使 用 名 为 < strong > BPF< / strong > 的 新 Linux内 核 技 术 ， Cilium提 供 了 一 种 基 于 容 器 /容 器 标 识 定 义 和 实 施 网 络 层 和 应 用 层 安 全 策 略 的 简 单 而 有 效 的 方 法 。 < / p >
< p > < strong > 注 < / strong > ： Cilium中 文 意 思 是 “ 纤 毛 “ ， 它 十 分 细 小 而 又 无 处 不 在 。 < / p >

< h2 id = "特性" > 特 性 < / h2 >
< p > 以 下 是 Cilium的 特 性 。 < / p >
< p > < strong > 基 于 身 份 的 安 全 性 < / strong > < / p >
< p > Cilium可 见 性 和 安 全 策 略 基 于 容 器 编 排 系 统 的 标 识 （ 例 如 ， Kubernetes中 的 Label） 。 在 编 写 安 全 策 略 、 审 计 和 故 障 排 查 时 ， 再 也 不 用 担 心 网 络 子 网 或 容 器 IP地 址 了 。 < / p >
< p > < strong > 卓 越 的 性 能 < / strong > < / p >
< p > BPF利 用 Linux底 层 的 强 大 能 力 ， 通 过 提 供 Linux内 核 的 沙 盒 可 编 程 性 来 实 现 数 据 路 径 ， 从 而 提 供 卓 越 的 性 能 。 < / p >
< p > < strong > API协 议 可 见 性 +安 全 性 < / strong > < / p >
< p > 传 统 防 火 墙 仅 根 据 IP地 址 和 端 口 等 网 络 标 头 查 看 和 过 滤 数 据 包 。 Cilium也 可 以 这 样 做 ， 但 也 可 以 理 解 并 过 滤 单 个 HTTP、 gRPC和 Kafka请 求 ， 这 些 请 求 将 微 服 务 拼 接 在 一 起 。 < / p >
< p > < strong > 专 为 扩 展 而 设 计 < / strong > < / p >
< p > Cilium是 为 扩 展 而 设 计 的 ， 在 部 署 新 pod时 不 需 要 节 点 间 交 互 ， 并 且 通 过 高 度 可 扩 展 的 键 值 存 储 进 行 所 有 协 调 。 < / p >
< h2 id = "为什么选择cilium？" > 为 什 么 选 择 Cilium？ < / h2 >
< p > 现 代 数 据 中 心 应 用 程 序 的 开 发 已 经 转 向 面 向 服 务 的 体 系 结 构 （ SOA） ， 通 常 称 为 < em > 微 服 务 < / em > ， 其 中 大 型 应 用 程 序 被 分 成 小 型 独 立 服 务 ， 这 些 服 务 使 用 HTTP等 轻 量 级 协 议 通 过 API相 互 通 信 。 微 服 务 应 用 程 序 往 往 是 高 度 动 态 的 ， 作 为 持 续 交 付 的 一 部 分 部 署 的 滚 动 更 新 期 间 单 个 容 器 启 动 或 销 毁 ， 应 用 程 序 扩 展 /缩 小 以 适 应 负 载 变 化 。 < / p >
< p > 这 种 向 高 度 动 态 的 微 服 务 的 转 变 过 程 ， 给 确 保 微 服 务 之 间 的 连 接 方 面 提 出 了 挑 战 和 机 遇 。 传 统 的 Linux网 络 安 全 方 法 （ 例 如 iptables） 过 滤 IP地 址 和 TCP/UDP端 口 ， 但 IP地 址 经 常 在 动 态 微 服 务 环 境 中 流 失 。 容 器 的 高 度 不 稳 定 的 生 命 周 期 导 致 这 些 方 法 难 以 与 应 用 程 序 并 排 扩 展 ， 因 为 负 载 均 衡 表 和 访 问 控 制 列 表 要 不 断 更 新 ， 可 能 增 长 成 包 含 数 十 万 条 规 则 。 出 于 安 全 目 的 ， 协 议 端 口 （ 例 如 ， 用 于 HTTP流 量 的 TCP端 口 80） 不 能 再 用 于 区 分 应 用 流 量 ， 因 为 该 端 口 用 于 跨 服 务 的 各 种 消 息 。 < / p >
< p > 另 一 个 挑 战 是 提 供 准 确 的 可 见 性 ， 因 为 传 统 系 统 使 用 IP地 址 作 为 主 要 识 别 工 具 ， 其 在 微 服 务 架 构 中 的 寿 命 可 能 才 仅 仅 几 秒 钟 ， 被 大 大 缩 短 。 < / p >
< p > 利 用 Linux BPF， Cilium保 留 了 透 明 地 插 入 安 全 可 视 性 +强 制 执 行 的 能 力 ， 但 这 种 方 式 基 于 服 务 /pod/容 器 标 识 （ 与 传 统 系 统 中 的 IP地 址 识 别 相 反 ） ， 并 且 可 以 根 据 应 用 层 进 行 过 滤 （ 例 如 HTTP） 。 因 此 ， 通 过 将 安 全 性 与 寻 址 分 离 ， Cilium不 仅 可 以 在 高 度 动 态 的 环 境 中 应 用 安 全 策 略 ， 而 且 除 了 提 供 传 统 的 第 3层 和 第 4层 分 割 之 外 ， 还 可 以 通 过 在 HTTP层 运 行 来 提 供 更 强 的 安 全 隔 离 。 。 < / p >
< p > BPF的 使 用 使 得 Cilium能 够 以 高 度 可 扩 展 的 方 式 实 现 以 上 功 能 ， 即 使 对 于 大 规 模 环 境 也 不 例 外 。 < / p >
< h2 id = "功能概述" > 功 能 概 述 < / h2 >
< h3 id = "透明的保护api" > 透 明 的 保 护 API< / h3 >
< p > 能 够 保 护 现 代 应 用 程 序 协 议 ， 如 REST/HTTP、 gRPC和 Kafka。 传 统 防 火 墙 在 第 3层 和 第 4层 运 行 ， 在 特 定 端 口 上 运 行 的 协 议 要 么 完 全 受 信 任 ， 要 么 完 全 被 阻 止 。 Cilium提 供 了 过 滤 各 个 应 用 程 序 协 议 请 求 的 功 能 ， 例 如 ： < / p >
< ul >
< li > 允 许 所 有 带 有 方 法 < code > GET< / code > 和 路 径 < code > /public/.*< / code > 的 HTTP请 求 。 拒 绝 所 有 其 他 请 求 。 < / li >
< li > 允 许 < code > service1< / code > 在 Kafka topic上 生 成 < code > topic1< / code > ， < code > service2< / code > 消 费 < code > topic1< / code > 。 拒 绝 所 有 其 他 Kafka消 息 。 < / li >
< li > 要 求 HTTP标 头 < code > X-Token: [0-9]+< / code > 出 现 在 所 有 REST调 用 中 。 < / li >
< / ul >
< p > 详 情 请 参 考 < a href = "http://docs.cilium.io/en/stable/policy/#layer-7" target = "_blank" > 7层 协 议 < / a > 。 < / p >
< h3 id = "基于身份来保护服务间通信" > 基 于 身 份 来 保 护 服 务 间 通 信 < / h3 >
< p > 现 代 分 布 式 应 用 程 序 依 赖 于 诸 如 容 器 之 类 的 技 术 来 促 进 敏 捷 性 并 按 需 扩 展 。 这 将 导 致 在 短 时 间 内 启 动 大 量 应 用 容 器 。 典 型 的 容 器 防 火 墙 通 过 过 滤 源 IP地 址 和 目 标 端 口 来 保 护 工 作 负 载 。 这 就 要 求 不 论 在 集 群 中 的 哪 个 位 置 启 动 容 器 时 都 要 操 作 所 有 服 务 器 上 的 防 火 墙 。 < / p >
< p > 为 了 避 免 受 到 规 模 限 制 ， Cilium为 共 享 相 同 安 全 策 略 的 应 用 程 序 容 器 组 分 配 安 全 标 识 。 然 后 ， 该 标 识 与 应 用 程 序 容 器 发 出 的 所 有 网 络 数 据 包 相 关 联 ， 从 而 允 许 验 证 接 收 节 点 处 的 身 份 。 使 用 键 值 存 储 执 行 安 全 身 份 管 理 。 < / p >
< h3 id = "安全访问外部服务" > 安 全 访 问 外 部 服 务 < / h3 >
< p > 基 于 标 签 的 安 全 性 是 集 群 内 部 访 问 控 制 的 首 选 工 具 。 为 了 保 护 对 外 部 服 务 的 访 问 ， 支 持 入 口 （ ingress） 和 出 口 （ egress） 的 传 统 基 于 CIDR的 安 全 策 略 。 这 允 许 限 制 对 应 用 程 序 容 器 的 访 问 以 及 对 特 定 IP范 围 的 访 问 。 < / p >
< h3 id = "简单网络" > 简 单 网 络 < / h3 >
< p > 一 个 简 单 的 扁 平 第 3层 网 络 能 够 跨 越 多 个 集 群 连 接 所 有 应 用 程 序 容 器 。 使 用 主 机 范 围 分 配 器 可 以 简 化 IP分 配 。 这 意 味 着 每 个 主 机 可 以 在 主 机 之 间 没 有 任 何 协 调 的 情 况 下 分 配 IP。 < / p >
< p > 支 持 以 下 多 节 点 网 络 模 型 ： < / p >
< ul >
< li > < p > < strong > Overlay< / strong > ： 基 于 封 装 的 虚 拟 网 络 产 生 所 有 主 机 。 目 前 VXLAN和 Geneve已 经 完 成 ， 但 可 以 启 用 Linux支 持 的 所 有 封 装 格 式 。 < / p >
< p > 何 时 使 用 此 模 式 ： 此 模 式 具 有 最 小 的 基 础 架 构 和 集 成 要 求 。 它 几 乎 适 用 于 任 何 网 络 基 础 架 构 ， 唯 一 的 要 求 是 主 机 之 间 可 以 通 过 IP连 接 。 < / p >
< / li >
< li > < p > < strong > 本 机 路 由 < / strong > ： 使 用 Linux主 机 的 常 规 路 由 表 。 网 络 必 须 能 够 路 由 应 用 程 序 容 器 的 IP地 址 。 < / p >
< p > 何 时 使 用 此 模 式 ： 此 模 式 适 用 于 高 级 用 户 ， 需 要 了 解 底 层 网 络 基 础 结 构 。 此 模 式 适 用 于 ： < / p >
< ul >
< li > 本 地 IPv6网 络 < / li >
< li > 与 云 网 络 路 由 器 配 合 使 用 < / li >
< li > 如 果 您 已 经 在 运 行 路 由 守 护 进 程 < / li >
< / ul >
< / li >
< / ul >
< h3 id = "负载均衡" > 负 载 均 衡 < / h3 >
< p > 应 用 程 序 容 器 和 外 部 服 务 之 间 的 流 量 的 分 布 式 负 载 均 衡 。 负 载 均 衡 使 用 BPF实 现 ， 允 许 几 乎 无 限 的 规 模 ， 并 且 如 果 未 在 源 主 机 上 执 行 负 载 均 衡 操 作 ， 则 支 持 直 接 服 务 器 返 回 （ DSR） 。 < / p >
< p > < strong > 注 意 < / strong > ： 负 载 均 衡 需 要 启 用 连 接 跟 踪 。 这 是 默 认 值 。 < / p >
< h3 id = "监控和故障排除" > 监 控 和 故 障 排 除 < / h3 >
< p > 可 见 性 和 故 障 排 查 是 任 何 分 布 式 系 统 运 行 的 基 础 。 虽 然 我 们 喜 欢 用 < code > tcpdump< / code > 和 < code > ping< / code > ， 它 们 很 好 用 ， 但 我 们 努 力 为 故 障 排 除 提 供 更 好 的 工 具 。 包 括 以 下 工 具 ： < / p >
< ul >
< li > 使 用 元 数 据 进 行 事 件 监 控 ： 当 数 据 包 被 丢 弃 时 ， 该 工 具 不 仅 仅 报 告 数 据 包 的 源 IP和 目 标 IP， 该 工 具 还 提 供 发 送 方 和 接 收 方 的 完 整 标 签 信 息 等 。 < / li >
< li > 策 略 决 策 跟 踪 ： 为 什 么 丢 弃 数 据 包 或 拒 绝 请 求 。 策 略 跟 踪 框 架 允 许 跟 踪 运 行 工 作 负 载 和 基 于 任 意 标 签 定 义 的 策 略 决 策 过 程 。 < / li >
< li > 通 过 Prometheus导 出 指 标 ： 通 过 Prometheus导 出 关 键 指 标 ， 以 便 与 现 有 仪 表 板 集 成 。 < / li >
