< h3 id = "ip分配" > IP分 配 < / h3 >
< p > 作 为 容 器 网 络 管 理 的 一 部 分 ， CNI插 件 需 要 为 接 口 分 配 （ 并 维 护 ） IP地 址 ， 并 安 装 与 该 接 口 相 关 的 所 有 必 要 路 由 。 这 给 了 CNI插 件 很 大 的 灵 活 性 ， 但 也 给 它 带 来 了 很 大 的 负 担 。 众 多 的 CNI插 件 需 要 编 写 相 同 的 代 码 来 支 持 用 户 需 要 的 多 种 IP管 理 方 案 （ 例 如 dhcp、 host-local） 。 < / p >
< p > 为 了 减 轻 负 担 ， 使 IP管 理 策 略 与 CNI插 件 类 型 解 耦 ， 我 们 定 义 了 IP地 址 管 理 插 件 （ IPAM插 件 ） 。 CNI插 件 的 职 责 是 在 执 行 时 恰 当 地 调 用 IPAM插 件 。 IPAM插 件 必 须 确 定 接 口 IP/subnet， 网 关 和 路 由 ， 并 将 此 信 息 返 回 到 “ 主 ” 插 件 来 应 用 配 置 。 IPAM插 件 可 以 通 过 协 议 （ 例 如 dhcp） 、 存 储 在 本 地 文 件 系 统 上 的 数 据 、 网 络 配 置 文 件 的 “ ipam” 部 分 或 上 述 的 组 合 来 获 得 信 息 。 < / p >
< h4 id = "ipam插件" > IPAM插 件 < / h4 >
< p > 像 CNI插 件 一 样 ， 调 用 IPAM插 件 的 可 执 行 文 件 。 可 执 行 文 件 位 于 预 定 义 的 路 径 列 表 中 ， 通 过 < code > CNI_PATH< / code > 指 示 给 CNI插 件 。 IPAM插 件 必 须 接 收 所 有 传 入 CNI插 件 的 相 同 环 境 变 量 。 就 像 CNI插 件 一 样 ， IPAM插 件 通 过 stdin接 收 网 络 配 置 。 < / p >
