< p > Kubernetes最 初 源 于 谷 歌 内 部 的 Borg， 提 供 了 面 向 应 用 的 容 器 集 群 部 署 和 管 理 系 统 。 Kubernetes的 目 标 旨 在 消 除 编 排 物 理 /虚 拟 计 算 ， 网 络 和 存 储 基 础 设 施 的 负 担 ， 并 使 应 用 程 序 运 营 商 和 开 发 人 员 完 全 将 重 点 放 在 以 容 器 为 中 心 的 原 语 上 进 行 自 助 运 营 。 Kubernetes 也 提 供 稳 定 、 兼 容 的 基 础 （ 平 台 ） ， 用 于 构 建 定 制 化 的 workflows 和 更 高 级 的 自 动 化 任 务 。
Kubernetes 具 备 完 善 的 集 群 管 理 能 力 ， 包 括 多 层 次 的 安 全 防 护 和 准 入 机 制 、 多 租 户 应 用 支 撑 能 力 、 透 明 的 服 务 注 册 和 服 务 发 现 机 制 、 内 建 负 载 均 衡 器 、 故 障 发 现 和 自 我 修 复 能 力 、 服 务 滚 动 升 级 和 在 线 扩 容 、 可 扩 展 的 资 源 自 动 调 度 机 制 、 多 粒 度 的 资 源 配 额 管 理 能 力 。
Kubernetes 还 提 供 完 善 的 管 理 工 具 ， 涵 盖 开 发 、 部 署 测 试 、 运 维 监 控 等 各 个 环 节 。 < / p >
< h2 id = "borg简介" > Borg简 介 < / h2 >
< p > Borg是 谷 歌 内 部 的 大 规 模 集 群 管 理 系 统 ， 负 责 对 谷 歌 内 部 很 多 核 心 服 务 的 调 度 和 管 理 。 Borg的 目 的 是 让 用 户 能 够 不 必 操 心 资 源 管 理 的 问 题 ， 让 他 们 专 注 于 自 己 的 核 心 业 务 ， 并 且 做 到 跨 多 个 数 据 中 心 的 资 源 利 用 率 最 大 化 。 < / p >
< p > Borg主 要 由 BorgMaster、 Borglet、 borgcfg和 Scheduler组 成 ， 如 下 图 所 示 < / p >
< figure id = "fig1.2.1" > < img src = "../images/borg.png" alt = "Borg架构" > < figcaption > Figure: Borg架 构 < / figcaption > < / figure >
< ul >
< li > BorgMaster是 整 个 集 群 的 大 脑 ， 负 责 维 护 整 个 集 群 的 状 态 ， 并 将 数 据 持 久 化 到 Paxos存 储 中 ； < / li >
< li > Scheduer负 责 任 务 的 调 度 ， 根 据 应 用 的 特 点 将 其 调 度 到 具 体 的 机 器 上 去 ； < / li >
< li > Borglet负 责 真 正 运 行 任 务 （ 在 容 器 中 ） ； < / li >
< li > borgcfg是 Borg的 命 令 行 工 具 ， 用 于 跟 Borg系 统 交 互 ， 一 般 通 过 一 个 配 置 文 件 来 提 交 任 务 。 < / li >
< / ul >
< h2 id = "kubernetes架构" > Kubernetes架 构 < / h2 >
< p > Kubernetes借 鉴 了 Borg的 设 计 理 念 ， 比 如 Pod、 Service、 Labels和 单 Pod单 IP等 。 Kubernetes的 整 体 架 构 跟 Borg非 常 像 ， 如 下 图 所 示 < / p >
< figure id = "fig1.2.2" > < img src = "../images/architecture.png" alt = "Kubernetes架构" > < figcaption > Figure: Kubernetes架 构 < / figcaption > < / figure >
< p > Kubernetes主 要 由 以 下 几 个 核 心 组 件 组 成 ： < / p >
< ul >
< li > etcd保 存 了 整 个 集 群 的 状 态 ； < / li >
< li > apiserver提 供 了 资 源 操 作 的 唯 一 入 口 ， 并 提 供 认 证 、 授 权 、 访 问 控 制 、 API注 册 和 发 现 等 机 制 ； < / li >
< li > controller manager负 责 维 护 集 群 的 状 态 ， 比 如 故 障 检 测 、 自 动 扩 展 、 滚 动 更 新 等 ； < / li >
< li > scheduler负 责 资 源 的 调 度 ， 按 照 预 定 的 调 度 策 略 将 Pod调 度 到 相 应 的 机 器 上 ； < / li >
< li > kubelet负 责 维 护 容 器 的 生 命 周 期 ， 同 时 也 负 责 Volume（ CVI） 和 网 络 （ CNI） 的 管 理 ； < / li >
< li > Container runtime负 责 镜 像 管 理 以 及 Pod和 容 器 的 真 正 运 行 （ CRI） ； < / li >
< li > kube-proxy负 责 为 Service提 供 cluster内 部 的 服 务 发 现 和 负 载 均 衡 ； < / li >
< / ul >
< p > 除 了 核 心 组 件 ， 还 有 一 些 推 荐 的 Add-ons： < / p >
< ul >
< li > kube-dns负 责 为 整 个 集 群 提 供 DNS服 务 < / li >
< li > Ingress Controller为 服 务 提 供 外 网 入 口 < / li >
< li > Heapster提 供 资 源 监 控 < / li >
< li > Dashboard提 供 GUI< / li >
< li > Federation提 供 跨 可 用 区 的 集 群 < / li >
