通过 Helm3 在 Kubernetes 上部署 EMQ X

通过 Helm3 在 Kubernetes 上部署 EMQ X

作者: EMQ | 来源:发表于2019-09-29 13:48 被阅读0次

Helm 在 2019 年 11 月发布了 Helm3 , Helm3 相比于 Helm2 增加了不少新特性, 本文介绍如何通过 Helm3 在 Kubernetes 上部署 EMQ X 集群.

Helm3 新特性

  • 移除了 Tiller

  • 不同的 namespace 可以使用相同的 Release Name

  • 简化模板对象 .Capabilities

  • 使用 JSONSchema 验证 charts 的 Values

  • 将 requirements.yaml合并到 Chart.yaml 中

  • helm install 时需要指定 Release Name，开启自动生成需要 --generate-name 参数

  • 支持 push 到远端 registry （如：harbor）

  • 移除 helm serve

  • 命令行变化（将原先的命令保留为别名 Aliases）

    • helm delete --> helm uninstall

    • helm inspect -> helm show

    • helm fetch -> helm pull

  • go 导入路径改变 k8s.io/helm --> helm.sh/helm

具体新特性可以参考 Helm 官方文档

Install Helm3

Helm3 提供了官方脚本简化了安装步骤, 可以执行 curl https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3 | bash 一键安装, 或者查看 Helm 官方文档 的详细说明

快速部署一个简单的 EMQ X 集群

  • 添加 helm 仓库

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n39" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">helm repo add emqx https://repos.emqx.io/charts helm repo update</pre>

  • 查询 EMQ X

  • 启动 EMQ X 集群，设置 service.type=NodePort

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n45" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm install my-emqx emqx/emqx --set service.type=NodePort</pre>

  • 查看 EMQ X 集群情况

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n48" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">kubectl get pods NAME READY STATUS RESTARTS AGE my-emqx-0 1/1 Running 0 56s my-emqx-1 1/1 Running 0 40s my-emqx-2 1/1 Running 0 21s ​ kubectl exec -it my-emqx-0 -- emqx_ctl cluster status
    Cluster status: #{running_nodes =>
    ['my-emqx@my-emqx-0.my-emqx-headless.default.svc.cluster.local',
    'my-emqx@my-emqx-1.my-emqx-headless.default.svc.cluster.local',
    'my-emqx@my-emqx-2.my-emqx-headless.default.svc.cluster.local'],
    stopped_nodes => []}</pre>

  • 查看 EMQ X service

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n51" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ kubectl get svc
    NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
    my-emqx NodePort 10.101.143.92 <none> 1883:32756/TCP,8883:31569/TCP,8081:30585/TCP,8083:31804/TCP,8084:30523/TCP,18083:31253/TCP 4m33s

可以看到 my-emqx 的 18083 端口对应的宿主机 IP 是 31539。（NodePort 在每次部署的时候都会变化，以实际部署时为准。）

  • 访问 Kubernetes 的任意一台节点 IP 的 31539 端口，输入默认用户名：admin，默认密码：public，登陆 EMQ X dashboard。

  • 删除 EMQ X 集群

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n58" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm uninstall my-emqx
    release "my-emqx" uninstalled</pre>

部署一个持久化的 EMQ X 集群

EMQ X 通过 创建 PVC 资源挂载 /opt/emqx/data/mnesia 目录实现持久化 pods，在部署 EMQ X 之前，用户需要部署 Haproxy 或 Nginx-PLUS 等负载均衡器，并自行在 Kubernetes 中创建 PVC 资源或是 Storage Classes 资源

  • 启动 EMQ X 集群

    • 如果用户部署了 PVC 资源，那么设置 persistence.existingClaim=your_pv_name

      <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n67" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm install my-emqx emqx/emqx --set persistence.enabled=true --set persistence.existingClaim=your_pv_name</pre>

    • 如果用户部署了 Storage Classes 资源，那么设置persistence.storageClass=your_storageClass_name

      <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n70" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm install my-emqx emqx/emqx --set persistence.enabled=true --set persistence.storageClass=your_storageClass_name</pre>

  • 查看 EMQ X 集群情况

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n73" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">kubectl get pods NAME READY STATUS RESTARTS AGE my-emqx-0 1/1 Running 0 56s my-emqx-1 1/1 Running 0 40s my-emqx-2 1/1 Running 0 21s ​ kubectl exec -it my-emqx-0 -- emqx_ctl cluster status
    Cluster status: #{running_nodes =>
    ['my-emqx@my-emqx-0.my-emqx-headless.default.svc.cluster.local',
    'my-emqx@my-emqx-1.my-emqx-headless.default.svc.cluster.local',
    'my-emqx@my-emqx-2.my-emqx-headless.default.svc.cluster.local'],
    stopped_nodes => []}</pre>

  • 以 Storage Classes 为例，可以看到 PVC 资源已经成功的建立

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n76" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ kubectl get pvc
    NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
    emqx-data-my-emqx-0 Bound pvc-8094cd75-adb5-11e9-80cc-0697b59e8064 1Gi RWO gp2 2m11s
    emqx-data-my-emqx-1 Bound pvc-9325441d-adb5-11e9-80cc-0697b59e8064 1Gi RWO gp2 99s
    emqx-data-my-emqx-2 Bound pvc-ad425e9d-adb5-11e9-80cc-0697b59e8064 1Gi RWO gp2 56s</pre>

    集群会将 EMQ X 的 /opt/emqx/data/mnesia 目录挂载到 PVC 中，当 Pods 被重新调度之后，EMQ X 会从 /opt/emqx/data/mnesia 目录中获取数据并恢复

  • 查看 EMQ X 的 ClusterIP

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n80" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;">$ kubectl get svc
    NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
    my-emqx ClusterIP 10.100.205.13 <none> 1883/TCP,8883/TCP,8081/TCP,8083/TCP,8084/TCP,18083/TCP 26m
    my-emqx-headless ClusterIP None <none> 1883/TCP,8883/TCP,8081/TCP,8083/TCP,8084/TCP,18083/TCP 26m</pre>

可以看到 my-emqx 的 ClusterIP 为 10.100.205.13 （ClusterIP 在每次部署的时候都会变化，以实际部署时为准。）

  • 将负载均衡监听的 URL 的 1883、8883、8081、8083、8084、18083 端口转发到 my-emqx 的 ClusterIP，如果有 TLS 连接的需要，推荐在负载均衡器终结 SSL 连接。客户端与负载均衡器之间 TLS 安全连接，LB 与 EMQ X 之间普通 TCP 连接。

  • 访问 URL:18083，输入默认用户名：admin，默认密码：public，登陆 EMQ X dashboard。

  • 使用 helm upgrade 命令可以轻松扩展 EMQ X 集群，下面以增加 EMQ X 节点为例展示 helm upgrade 命令

    <pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n90" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; background-position: inherit inherit; background-repeat: inherit inherit;"># 将 EMQ X 的节点数量变更为5个

    注意：EMQ X 的节点数量建议为单数

    $ helm upgrade --set replicaCount=5 my-emqx emqx/emqx
    Release "my-emqx" has been upgraded. Happy Helming!</pre>

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n88" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; background-position: inherit inherit; background-repeat: inherit inherit;"> kubectl get pods NAME READY STATUS RESTARTS AGE my-emqx-0 1/1 Running 0 4m25s my-emqx-1 1/1 Running 0 4m14s my-emqx-2 1/1 Running 0 4m my-emqx-3 1/1 Running 0 31s my-emqx-4 1/1 Running 0 15s ​ kubectl exec -it my-emqx-0 -- emqx_ctl cluster status

EMQ X EE

部署 EMQ X 企业版集群首先需要登陆 emqx.io](https://emqx.io) 申请并下载 License 文件，并将 License 文件创建为 Secret 资源

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n104" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; background-position: inherit inherit; background-repeat: inherit inherit;">$ kubectl create secret generic your-license-secret-name --from-file=/path/to/emqx.lic</pre>

然后在部署时指定 repo 为 emqx/emqx-ee, emqxLicneseSecretName=your-license-secret-name, 其他设置与部署 EMQ X 集群保持一致

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n106" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm install my-emqx-ee emqx/emqx-ee emqxLicneseSecretName=your-license-secret-name</pre>

EMQ X Helm Chart 配置项

参数 描述 Default Value
replicaCount EMQ X 节点数量，建议保持奇数个节点，不然脑裂后无法自动恢复 3
image.repository EMQ X 镜像名称 emqx/emqx
image.pullPolicy 获取镜像的策略 IfNotPresent
persistence.enabled 是否启用 PVC false
persistence.storageClass Storage class 名称 nil
persistence.existingClaim PV 名称 ""
persistence.accessMode PVC 访问模式 ReadWriteOnce
persistence.size PVC 容量 20Mi
resources CPU/ 内存资源 {}
nodeSelector pod 分配的节点标签 {}
tolerations []
affinity {}
service.type Emqx cluster service type ClusterIP
emqxConfig EMQ X 配置项，详情查看文档 {}
emqxLicneseSecretName EMQ X 企业版需要手动将 License 文件创建为 Secret 资源 (仅在 emqx/emqx-e 有效) ""

当需要设置复杂参数的时候，可以使用 Yaml 文件来记录参数

<pre spellcheck="false" class="md-fences md-end-block ty-contain-cm modeLoaded" lang="" cid="n174" mdtype="fences" style="box-sizing: border-box; overflow: visible; font-family: var(--monospace); font-size: 0.9em; display: block; break-inside: avoid; text-align: left; white-space: normal; background-image: inherit; background-size: inherit; background-attachment: inherit; background-origin: inherit; background-clip: inherit; background-color: rgb(248, 248, 248); position: relative !important; border: 1px solid rgb(231, 234, 237); border-top-left-radius: 3px; border-top-right-radius: 3px; border-bottom-right-radius: 3px; border-bottom-left-radius: 3px; padding: 8px 4px 6px; margin-bottom: 15px; margin-top: 15px; width: inherit; caret-color: rgb(51, 51, 51); color: rgb(51, 51, 51); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-indent: 0px; text-transform: none; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; text-decoration: none; background-position: inherit inherit; background-repeat: inherit inherit;">$ helm install my-emqx emqx/emqx -f values.yaml </pre>

你可以从 Github 获取默认的 values.yaml
