前言
最近在应用 k8s 搭建微服务时，发现须要手动批改 yaml 文件外面的 pod name、pod image、svc name、ingress tls 等等，十分麻烦，然而有了 helm 之后状况就不一样了，helm 是 k8s 的包管理器，相似 ubuntu 的 apt-get，centos 的 yum 一样，有了 helm 安装包就十分不便了，上面就解说通过 helm 来装置 rabbitmq。
筹备工作
- 装置 k8s
我应用的是阿里云的 ACK k8s 服务。 - 装置 k8s 客户端:kubectl
kubectl 装置地址 - 装置 helm 客户端
装置 helm -
配置 helm repo 源
上面是我增加的三个源：stable、bitnami 和 alihelm repo add stable https://charts.helm.sh/stable helm repo add bitnami https://charts.helm.sh/stable helm repo add ali https://charts.helm.sh/stable查看曾经装置好的 repo 源
$ helm repo list NAME URL stable https://charts.helm.sh/stable bitnami https://charts.bitnami.com/bitnami ali https://apphub.aliyuncs.com/stable/
rabbitmq 装置形式
装置 rabbitmq 办法有很多上面列举几个惯例装置办法：
- centos 7/ 8 装置 rabbitmq 阿里云 ECS CentOS 提供装置
- k8s 装置 rabbitmq 官网文档提供装置
- helm 装置 rabbitmq 社区大佬提供装置
helm 装置 rabbitmq
这里咱们应用 helm 来装置 rabbitmq，首先咱们看看 helm 外面有没有 rabbitmq 的 chart，
$ helm search repo rabbitmq

stable/rabbitmq-ha 1.47.1 3.8.7 DEPRECATED - Highly available RabbitMQ cluster,...能够看到不同的 repo 源提供的 rabbitmq 的 chart 的版本也不同，咱们选用的是 stable/rabbitmq，chart 版本：6.18.2，APP 版本：3.8.2。
接着，咱们要把 stable/rabbitmq 的 chart 文件下载下来，下载下来的 chart 文件是.tgz 的压缩文件，解压一下即可，
helm pull stable/rabbitmq
tar zxf rabbitmq-6.18.2.tgz$ cd rabbitmq && ls -ls

## because the first RabbitMQ of the statefulset always will be last of the cluster.

values.yaml 文件是 helm chart 对外公开的配置信息，可依据须要自行批改，因为咱们应用的是阿里云，所以存储应用 alicloud-disk-ssd，留神 alicloud-disk-ssd 最低要求 ssd 为 20G：
storageClass: "alicloud-disk-ssd"
size: 20Gi因为咱们要通过域名拜访所以要启用 ingress 及域名配置：
ingress:
enabled: true
annotations:
kubernetes.io/ingress.class: nginx
hostName: rabbitmq.baidu.com最初就是要通过 https 拜访，咱们要启用 tls：
tls: true
tlsSecret: tls-secret-name这里咱们留神一下，因为我应用的是 cert-manager.io/cluster-issuer 注解(我曾经在 k8s 中曾经生成了)，所以能够间接生成了 tls 证书，十分不便，感兴趣的能够看看应用 cert-manager 申请收费的 HTTPS 证书
annotations:
cert-manager.io/cluster-issuer: your-cert-manager-name最终残缺的 values.yaml 文件如下：

NOTES:
This Helm chart is deprecated
Given the `stable` deprecation timeline (https://github.com/helm/charts#deprecation-timeline), the Bitnami maintained RabbitMQ Helm chart is now located at bitnami/charts (https://github.com/bitnami/charts/).
The Bitnami repository is already included in the Hubs and we will continue providing the same cadence of updates, support, etc that we've been keeping here these years. Installation instructions are very similar, just adding the _bitnami_ repo and using it during the installation (`bitnami/<chart>` instead of `stable/<chart>`)
$ helm repo add bitnami https://charts.bitnami.com/bi…
$ helm install my-release bitnami/<chart> # Helm 3
$ helm install –name my-release bitnami/<chart> # Helm 2
To update an exisiting _stable_ deployment with a chart hosted in the bitnami repository you can execute$ helm upgrade my-release bitnami/<chart>
Issues and PRs related to the chart itself will be redirected to `bitnami/charts` GitHub repository. In the same way, we'll be happy to answer questions related to this migration process in this issue (https://github.com/helm/charts/issues/20969) created as a common place for discussion.

statefulset.apps/test-rabbitmq 1/1 3h56m期待一段时间会发现 pod、svc、ingress、pvc、pv、statefulset 全副创立实现，即可拜访 rabbitmq 了！
问题
- 拜访 rabbitmq 报：503
如果你配置的域名门路如：baidu.com/rabbitmq，这样的域名，那么你要配置成上面这样，能力正确拜访，参考这篇文章：
rabbitmq:
extraConfiguration: |-
management.path_prefix = /rabbitmq/
ingress:
...
hostName: baidu.com
path: /rabbitmq/
...kubectl describe svc your-service-name -n rabbit发现 service endpoint 为空
- 起因：pvc 没有删除参考这篇文章理解
-
解决：
kubectl get pvc kubectl delete pvc <name>
- running “VolumeBinding” filter plugin for pod “test-rabbitmq-0”: pod has unbound immediate PersistentVolumeClaims
- 起因：要设置 storageClass 以及阿里云盘最低要求 20Gi
-
解决：
persistence: storageClass: "alicloud-disk-ssd" size: 20Gi
- PersistentVolumeClaim “data-test-rabbitmq-0” is invalid: spec: Forbidden: is immutable after creation except resources.requests for bound claims
- 起因：pvc 的容器不反对在线批改的
- 解决：删除 pvc 从新创立
- Warning ProvisioningFailed 6s (x4 over 14m) diskplugin.csi.alibabacloud.com_iZbp1d2cbgi4jt9oty4m9iZ_3408e051-98e8-4295-8a21-7f1af0807958 (combined from similar events): failed to provision volume with StorageClass “alicloud-disk-ssd”: rpc error: code = Internal desc = SDK.ServerError
ErrorCode: InvalidAccountStatus.NotEnoughBalance
- 起因：阿里云账户余额最低 100 元能力创立 ssd 云盘
- 解决：阿里云账户充值
- 登录 rabbitmq 报 401
起因：明码谬误
解决：运行上面命令获取明码
echo "Password : $(kubectl get secret --namespace rabbit test-rabbitmq -o jsonpath="{.data.rabbitmq-password}"| base64 --decode)"
总结
1、kubectl 要配置 k8s 的连贯配置信息能力应用，而 helm 默认就拿到了连贯信息，默认是在~/.kube/config
2、helm3 曾经移除了 helm tillers 和 helm init 命令，所以就不要探讨 helm2 了。
3、如果装置过程中或者之后呈现谬误，能够通过阿里云 ack 管制台下的利用 ->helm release 列表删除即可。
4、不须要配置rabbitmq-plugins enable rabbitmq_management，因为 helm 装置 rabbitmq 后默认启动了。
5、如果不是阿里云的 rabbitmq 太贵，我才不违心本人装呢，唉，被逼的。
