< p > 其 实 ConfigMap功 能 在 Kubernetes1.2版 本 的 时 候 就 有 了 , 许 多 应 用 程 序 会 从 配 置 文 件 、 命 令 行 参 数 或 环 境 变 量 中 读 取 配 置 信 息 。 这 些 配 置 信 息 需 要 与 docker image解 耦 , 你 总 不 能 每 修 改 一 个 配 置 就 重 做 一 个 image吧 ? ConfigMap API给 我 们 提 供 了 向 容 器 中 注 入 配 置 信 息 的 机 制 , ConfigMap可 以 被 用 来 保 存 单 个 属 性 , 也 可 以 用 来 保 存 整 个 配 置 文 件 或 者 JSON二 进 制 大 对 象 。 < / p >
