< p > 使 用 案 例 参 考 ： < a href = "https://github.com/kubernetes/contrib/tree/master/statefulsets" target = "_blank" > kubernetes contrib - statefulsets< / a > ， 其 中 包 含 zookeeper和 kakfa的 statefulset设 置 和 使 用 说 明 。 < / p >

< p > StatefulSet是 为 了 解 决 有 状 态 服 务 的 问 题 （ 对 应 Deployments和 ReplicaSets是 为 无 状 态 服 务 而 设 计 ） ， 其 应 用 场 景 包 括 ： < / p >
< ul >
< li > 稳 定 的 持 久 化 存 储 ， 即 Pod重 新 调 度 后 还 是 能 访 问 到 相 同 的 持 久 化 数 据 ， 基 于 PVC来 实 现 < / li >
< li > 稳 定 的 网 络 标 志 ， 即 Pod重 新 调 度 后 其 PodName和 HostName不 变 ， 基 于 Headless Service（ 即 没 有 Cluster IP的 Service） 来 实 现 < / li >
< li > 有 序 部 署 ， 有 序 扩 展 ， 即 Pod是 有 顺 序 的 ， 在 部 署 或 者 扩 展 的 时 候 要 依 据 定 义 的 顺 序 依 次 依 次 进 行 （ 即 从 0到 N-1， 在 下 一 个 Pod运 行 之 前 所 有 之 前 的 Pod必 须 都 是 Running和 Ready状 态 ） ， 基 于 init containers来 实 现 < / li >
< li > 有 序 收 缩 ， 有 序 删 除 （ 即 从 N-1到 0） < / li >
< / ul >
< p > 从 上 面 的 应 用 场 景 可 以 发 现 ， StatefulSet由 以 下 几 个 部 分 组 成 ： < / p >
< ul >
< li > 用 于 定 义 网 络 标 志 （ DNS domain） 的 Headless Service< / li >
< li > 用 于 创 建 PersistentVolumes的 volumeClaimTemplates< / li >
< li > 定 义 具 体 应 用 的 StatefulSet< / li >
< / ul >
< p > StatefulSet中 每 个 Pod的 DNS格 式 为 < code > statefulSetName-{0..N-1}.serviceName.namespace.svc.cluster.local< / code > ， 其 中 < / p >
< ul >
< li > < code > serviceName< / code > 为 Headless Service的 名 字 < / li >
< li > < code > 0..N-1< / code > 为 Pod所 在 的 序 号 ， 从 0开 始 到 N-1< / li >
< li > < code > statefulSetName< / code > 为 StatefulSet的 名 字 < / li >
< li > < code > namespace< / code > 为 服 务 所 在 的 namespace， Headless Servic和 StatefulSet必 须 在 相 同 的 namespace< / li >
< li > < code > .cluster.local< / code > 为 Cluster Domain< / li >
< / ul >
< h2 id = "使用-statefulset" > 使 用 StatefulSet< / h2 >
< p > StatefulSet 适 用 于 有 以 下 某 个 或 多 个 需 求 的 应 用 ： < / p >
< ul >
< li > 稳 定 ， 唯 一 的 网 络 标 志 。 < / li >
< li > 稳 定 ， 持 久 化 存 储 。 < / li >
< li > 有 序 ， 优 雅 地 部 署 和 scale。 < / li >
< li > 有 序 ， 优 雅 地 删 除 和 终 止 。 < / li >
< li > 有 序 ， 自 动 的 滚 动 升 级 。 < / li >
< / ul >
< p > 在 上 文 中 ， 稳 定 是 Pod （ 重 新 ） 调 度 中 持 久 性 的 代 名 词 。 如 果 应 用 程 序 不 需 要 任 何 稳 定 的 标 识 符 、 有 序 部 署 、 删 除 和 scale， 则 应 该 使 用 提 供 一 组 无 状 态 副 本 的 controller 来 部 署 应 用 程 序 ， 例 如 < a href = "https://kubernetes.io/docs/concepts/workloads/controllers/deployment" target = "_blank" > Deployment< / a > 或 < a href = "https://kubernetes.io/docs/concepts/workloads/controllers/replicaset" target = "_blank" > ReplicaSet< / a > 可 能 更 适 合 您 的 无 状 态 需 求 。 < / p >
< h2 id = "限制" > 限 制 < / h2 >
< ul >
< li > StatefulSet 是 beta 资 源 ， Kubernetes 1.5 以 前 版 本 不 支 持 。 < / li >
< li > 对 于 所 有 的 alpha/beta 的 资 源 ， 您 都 可 以 通 过 在 apiserver 中 设 置 < code > --runtime-config< / code > 选 项 来 禁 用 。 < / li >
< li > 给 定 Pod 的 存 储 必 须 由 < a href = "http://releases.k8s.io/%7B%7Bpage.githubbranch%7D%7D/examples/persistent-volume-provisioning/README.md" target = "_blank" > PersistentVolume Provisioner< / a > 根 据 请 求 的 < code > storage class< / code > 进 行 配 置 ， 或 由 管 理 员 预 先 配 置 。 < / li >
< li > 删 除 或 scale StatefulSet 将 < em > 不 会 < / em > 删 除 与 StatefulSet 相 关 联 的 volume。 这 样 做 是 为 了 确 保 数 据 安 全 性 ， 这 通 常 比 自 动 清 除 所 有 相 关 StatefulSet 资 源 更 有 价 值 。 < / li >
< li > StatefulSets 目 前 要 求 < a href = "https://kubernetes.io/docs/concepts/services-networking/service/#headless-services" target = "_blank" > Headless Service< / a > 负 责 Pod 的 网 络 身 份 。 您 有 责 任 创 建 此 服 务 。 < / li >
< / ul >
< h2 id = "组件" > 组 件 < / h2 >
< p > 下 面 的 示 例 中 描 述 了 StatefulSet 中 的 组 件 。 < / p >
< ul >
< li > 一 个 名 为 nginx 的 headless service， 用 于 控 制 网 络 域 。 < / li >
< li > 一 个 名 为 web 的 StatefulSet， 它 的 Spec 中 指 定 在 有 3 个 运 行 nginx 容 器 的 Pod。 < / li >
< li > volumeClaimTemplates 使 用 PersistentVolume Provisioner 提 供 的 < a href = "https://kubernetes.io/docs/concepts/storage/volumes" target = "_blank" > PersistentVolumes< / a > 作 为 稳 定 存 储 。 < / li >

< p > StatefulSet 中 的 每 个 Pod 从 StatefulSet 的 名 称 和 Pod 的 序 数 派 生 其 主 机 名 。 构 造 的 主 机 名 的 模 式 是 < code > $（ statefulset名 称 )-$(序 数 )< / code > 。 上 面 的 例 子 将 创 建 三 个 名 为 < code > web-0， web-1， web-2< / code > 的 Pod。 < / p >
< p > StatefulSet 可 以 使 用 < a href = "https://kubernetes.io/docs/concepts/services-networking/service/#headless-services" target = "_blank" > Headless Service< / a > 来 控 制 其 Pod 的 域 。 此 服 务 管 理 的 域 的 格 式 为 ： < code > $(服 务 名 称 ).$(namespace).svc.cluster.local< / code > ， 其 中 “ cluster.local” 是 < a href = "http://releases.k8s.io/%7B%7Bpage.githubbranch%7D%7D/cluster/addons/dns/README.md" target = "_blank" > 集 群 域 < / a > 。 < / p >

< h3 id = "稳定存储" > 稳 定 存 储 < / h3 >
< p > Kubernetes 为 每 个 VolumeClaimTemplate 创 建 一 个 < a href = "https://kubernetes.io/docs/concepts/storage/volumes" target = "_blank" > PersistentVolume< / a > 。 上 面 的 nginx 的 例 子 中 ， 每 个 Pod 将 具 有 一 个 由 < code > anything< / code > 存 储 类 创 建 的 1 GB 存 储 的 PersistentVolume。 当 该 Pod （ 重 新 ） 调 度 到 节 点 上 ， < code > volumeMounts< / code > 将 挂 载 与 PersistentVolume Claim 相 关 联 的 PersistentVolume。 请 注 意 ， 与 PersistentVolume Claim 相 关 联 的 PersistentVolume 在 产 出 Pod 或 StatefulSet 的 时 候 不 会 被 删 除 。 这 必 须 手 动 完 成 。 < / p >

< li > 对 Pod 执 行 scale 操 作 之 前 ， 它 所 有 的 前 任 必 须 处 于 Running 和 Ready 状 态 。 < / li >
< li > 在 终 止 Pod 前 ， 它 所 有 的 继 任 者 必 须 处 于 完 全 关 闭 状 态 。 < / li >
< / ul >
< p > 不 应 该 将 StatefulSet 的 < code > pod.Spec.TerminationGracePeriodSeconds< / code > 设 置 为 0。 这 样 是 不 安 全 的 且 强 烈 不 建 议 您 这 样 做 。 进 一 步 解 释 ， 请 参 阅 < a href = "https://kubernetes.io/docs/tasks/run-application/force-delete-stateful-set-pod" target = "_blank" > 强 制 删 除 StatefulSet Pod< / a > 。 < / p >
< p > 上 面 的 nginx 示 例 创 建 后 ， 3 个 Pod 将 按 照 如 下 顺 序 创 建 web-0， web-1， web-2。 在 web-0 处 于 < a href = "https://kubernetes.io/docs/user-guide/pod-states" target = "_blank" > 运 行 并 就 绪 < / a > 状 态 之 前 ， web-1 将 不 会 被 部 署 ， 同 样 当 web-1 处 于 运 行 并 就 绪 状 态 之 前 web-2也 不 会 被 部 署 。 如 果 在 web-1 运 行 并 就 绪 后 ， web-2 启 动 之 前 ， web-0 失 败 了 ， web-2 将 不 会 启 动 ， 直 到 web-0 成 果 重 启 并 处 于 运 行 并 就 绪 状 态 。 < / p >
< p > 如 果 用 户 通 过 修 补 StatefulSet 来 scale 部 署 的 示 例 ， 以 使 < code > replicas=1< / code > ， 则 web-2 将 首 先 被 终 止 。 在 web-2 完 全 关 闭 和 删 除 之 前 ， web-1 不 会 被 终 止 。 如 果 web-0 在 web-2 终 止 并 且 完 全 关 闭 之 后 ， 但 是 在 web-1 终 止 之 前 失 败 ， 则 web-1 将 不 会 终 止 ， 除 非 web-0 正 在 运 行 并 准 备 就 绪 。 < / p >
< h3 id = "pod-管理策略" > Pod 管 理 策 略 < / h3 >
< p > 在 Kubernetes 1.7 和 之 后 版 本 ， StatefulSet 允 许 您 放 开 顺 序 保 证 ， 同 时 通 过 < code > .spec.podManagementPolicy< / code > 字 段 保 证 身 份 的 唯 一 性 。 < / p >

< h2 id = "更新策略" > 更 新 策 略 < / h2 >
< p > 在 kubernetes 1.7 和 以 上 版 本 中 ， StatefulSet 的 < code > .spec.updateStrategy< / code > 字 段 允 许 您 配 置 和 禁 用 StatefulSet 中 的 容 器 、 label、 resource request/limit、 annotation 的 滚 动 更 新 。 < / p >
< h3 id = "删除" > 删 除 < / h3 >
< p > < code > OnDelete< / code > 更 新 策 略 实 现 了 遗 留 （ 1.6和 以 前 ） 的 行 为 。 当 < code > spec.updateStrategy< / code > 未 指 定 时 ， 这 是 默 认 策 略 。 当 StatefulSet 的 < code > .spec.updateStrategy.type< / code > 设 置 为 < code > OnDelete< / code > 时 ， StatefulSet 控 制 器 将 不 会 自 动 更 新 < code > StatefulSet< / code > 中 的 Pod。 用 户 必 须 手 动 删 除 Pod 以 使 控 制 器 创 建 新 的 Pod， 以 反 映 对 StatefulSet的 < code > .spec.template< / code > 进 行 的 修 改 。 < / p >
< h3 id = "滚动更新" > 滚 动 更 新 < / h3 >
< p > < code > RollingUpdate< / code > 更 新 策 略 在 StatefulSet 中 实 现 Pod 的 自 动 滚 动 更 新 。 当 StatefulSet的 < code > .spec.updateStrategy.type< / code > 设 置 为 < code > RollingUpdate< / code > 时 ， StatefulSet 控 制 器 将 在 StatefulSet 中 删 除 并 重 新 创 建 每 个 Pod。 它 将 以 与 Pod 终 止 相 同 的 顺 序 进 行 （ 从 最 大 的 序 数 到 最 小 的 序 数 ） ， 每 次 更 新 一 个 Pod。 在 更 新 其 前 身 之 前 ， 它 将 等 待 正 在 更 新 的 Pod 状 态 变 成 正 在 运 行 并 就 绪 。 < / p >
< h4 id = "分区" > 分 区 < / h4 >
< p > 可 以 通 过 指 定 < code > .spec.updateStrategy.rollingUpdate.partition< / code > 来 对 < code > RollingUpdate< / code > 更 新 策 略 进 行 分 区 。 如 果 指 定 了 分 区 ， 则 当 StatefulSet 的 < code > .spec.template< / code > 更 新 时 ， 具 有 大 于 或 等 于 分 区 序 数 的 所 有 Pod 将 被 更 新 。 具 有 小 于 分 区 的 序 数 的 所 有 Pod 将 不 会 被 更 新 ， 即 使 删 除 它 们 也 将 被 重 新 创 建 。 如 果 StatefulSet 的 < code > .spec.updateStrategy.rollingUpdate.partition< / code > 大 于 其 < code > .spec.replicas< / code > ， 则 其 < code > .spec.template< / code > 的 更 新 将 不 会 传 播 到 Pod。 < / p >
< p > 在 大 多 数 情 况 下 ， 您 不 需 要 使 用 分 区 ， 但 如 果 您 想 要 进 行 分 阶 段 更 新 ， 使 用 金 丝 雀 发 布 或 执 行 分 阶 段 发 布 ， 它 们 将 非 常 有 用 。 < / p >
