< p > 在 本 文 中 ， 我 们 将 介 绍 容 器 存 储 的 首 选 以 及 如 何 部 署 它 。 Kusternet和 OpenShift支 持 GlusterFS已 经 有 一 段 时 间 了 。 GlusterFS的 适 用 性 很 好 ， 可 用 于 所 有 的 部 署 场 景 ： 裸 机 、 虚 拟 机 、 内 部 部 署 和 公 共 云 。 在 容 器 中 运 行 GlusterFS的 新 特 性 将 在 本 系 列 后 面 讨 论 。 < / p >
< p > GlusterFS是 一 个 分 布 式 文 件 系 统 ， 内 置 了 原 生 协 议 （ GlusterFS） 和 各 种 其 他 协 议 （ NFS， SMB， ...） 。 为 了 与 OpenShift集 成 ， 节 点 将 通 过 FUSE使 用 原 生 协 议 ， 将 GlusterFS卷 挂 在 到 节 点 本 身 上 ， 然 后 将 它 们 绑 定 到 目 标 容 器 中 。 OpenShift / Kubernetes具 有 实 现 请 求 、 释 放 和 挂 载 、 卸 载 GlusterFS卷 的 原 生 程 序 。 < / p >
< h3 id = "crs概述" > CRS概 述 < / h3 >
< p > 在 存 储 方 面 ， 根 据 OpenShift / Kubernetes的 要 求 ， 还 有 一 个 额 外 的 组 件 管 理 集 群 ， 称 为 “ heketi” 。 这 实 际 上 是 一 个 用 于 GlusterFS的 REST API， 它 还 提 供 CLI版 本 。 在 以 下 步 骤 中 ， 我 们 将 在 3个 GlusterFS节 点 中 部 署 heketi， 使 用 它 来 部 署 GlusterFS存 储 池 ， 将 其 连 接 到 OpenShift， 并 使 用 它 来 通 过 PersistentVolumeClaims为 容 器 配 置 存 储 。 我 们 将 总 共 部 署 4台 虚 拟 机 。 一 个 用 于 OpenShift（ 实 验 室 设 置 ） ， 另 一 个 用 于 GlusterFS。 < / p >

< h3 id = "部署openshift" > 部 署 OpenShift< / h3 >
< p > 首 先 你 需 要 先 部 署 OpenShift。 最 有 效 率 的 方 式 是 直 接 在 虚 拟 机 中 部 署 一 个 All-in-One环 境 ， 部 署 指 南 见 < a href = "https://keithtenzer.com/2017/03/13/openshift-enterprise-3-4-all-in-one-lab-environment/" target = "_blank" > the “ OpenShift Enterprise 3.4 all-in-one Lab Environment” article.< / a > 。 < / p >

< p > What happened in the background was that when the PVC reached the system, our default StorageClass reached out to the GlusterFS Provisioner with the volume specs from the PVC. The provisioner in turn communicates with our heketi instance which facilitates the creation of the GlusterFS volume, which we can trace in it’ s log messages:< / p >
< p > 该 volume是 根 据 PVC中 的 定 义 特 别 创 建 的 。 在 PVC中 ， 我 们 没 有 明 确 指 定 要 使 用 哪 个 StorageClass， 因 为 heketi的 GlusterFS StorageClass已 经 被 定 义 为 系 统 范 围 的 默 认 值 。 < / p >
< p > 在 后 台 发 生 的 情 况 是 ， 当 PVC到 达 系 统 时 ， 默 认 的 StorageClass请 求 具 有 该 PVC中 volume声 明 规 格 的 GlusterFS Provisioner。 Provisioner又 与 我 们 的 heketi实 例 通 信 ， 这 有 助 于 创 建 GlusterFS volume， 我 们 可 以 在 其 日 志 消 息 中 追 踪 ： < / p >

< h3 id = "总结" > 总 结 < / h3 >
< p > 在 这 里 我 们 是 在 OpenShift之 外 创 建 了 一 个 简 单 但 功 能 强 大 的 GlusterFS存 储 池 。 该 池 可 以 独 立 于 应 用 程 序 扩 展 和 收 缩 。 该 池 的 整 个 生 命 周 期 由 一 个 简 单 的 称 为 heketi的 前 端 管 理 ， 你 只 需 要 在 部 署 增 长 时 进 行 手 动 干 预 。 对 于 日 常 配 置 操 作 ， 使 用 它 的 API与 OpenShifts动 态 配 置 器 交 互 ， 无 需 开 发 人 员 直 接 与 基 础 架 构 团 队 进 行 交 互 。 < / p >
< p > o这 就 是 我 们 如 何 将 存 储 带 入 DevOps世 界 - 无 痛 苦 ， 并 在 OpenShift PaaS系 统 的 开 发 人 员 工 具 中 直 接 提 供 。 < / p >
< p > GlusterFS和 OpenShift可 跨 越 所 有 环 境 ： 裸 机 ， 虚 拟 机 ， 私 有 和 公 共 云 （ Azure， Google Cloud， AWS ...） ， 确 保 应 用 程 序 可 移 植 性 ， 并 避 免 云 供 应 商 锁 定 。 < / p >
