如何在 Kubernetes 中部署 ThingsBoard？
众所周知，Kubernetes（k8s）太火了，太牛了，咱们把部署在 ThingsBoard 上更是理所当然。一句话总结：步骤很简单，过程很艰辛！
- 准备工作
- 安装
- 测试
准备 Docker 和 Kubernetes 环境
安装 Docker Desktop CE 版本
- 笔者使用的老版本 MacBook Pro 13，下载安装 Docker Desktop CE 版本，这个比较简单，官方下载，安装即可完成，启动。
K8S
- 启用 Docker Desktop 中 Kubernetes
启动 K8S
哇塞，是不是太简单了？当然不会那么容易搞定，你会一直出现 “Starting” 的状态，别傻等，要去 Google 一下。关键字：如何成功启动 Docker 自带的 Kubernetes？ 总之，你一定要找到办法解决你的 Kubernetes 成功启动。
安装 Kubenetes 本地版本
- 安装 Kubernetes，就是简单，本地安装搞定
# brew install kubernetes-cli
# kubectl version --client
Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.4", GitCommit:"d360454c9bcd1634cf4cc52d1867af5491dc9c5f", GitTreeState:"clean", BuildDate:"2020-11-12T01:09:16Z", GoVersion:"go1.15.4", Compiler:"gc", Platform:"darwin/amd64"}
- 为了让 Docker Desktop 启动 k8s，需下载相关的 docker images，需要通过一个脚本 docker-images-k8s.sh，然后运行，从 aliyun 下载 docker image 比较快。
#!/bin/bash
set -e
KUBE_VERSION=v1.19.3
KUBE_PAUSE_VERSION=3.2
ETCD_VERSION=3.4.13-0
COREDNS_VERSION=1.7.0
GCR_URL=k8s.gcr.io
ALIYUN_URL=registry.cn-hangzhou.aliyuncs.com/google_containers
# get images
images=(kube-proxy:${KUBE_VERSION}
kube-scheduler:${KUBE_VERSION}
kube-controller-manager:${KUBE_VERSION}
kube-apiserver:${KUBE_VERSION}
pause:${KUBE_PAUSE_VERSION}
etcd:${ETCD_VERSION}
coredns:${COREDNS_VERSION})
for imageName in ${images[@]} ; do
docker pull $ALIYUN_URL/$imageName
docker tag $ALIYUN_URL/$imageName $GCR_URL/$imageName
docker rmi $ALIYUN_URL/$imageName
done
# show images
docker images
- 为了查看 k8s 运行状态，web 管理工具 kubernetes dashboard 自然少不了，新建 docker-images-dashboard.sh，运行
#!/bin/bash
set -e
KUBE_DASHBOARD_VERSION=v2.0.3
METRICS_SCRAPER=v1.0.4
KUBENETESUI_URL=kubernetesui
ALIYUN_KUBENETESUI_URL=registry.cn-hangzhou.aliyuncs.com/kubernetes_ns
# get images (ui)
imagesui=(dashboard:${KUBE_DASHBOARD_VERSION}
metrics-scraper:${METRICS_SCRAPER})
for imageName in ${imagesui[@]} ; do
docker pull $ALIYUN_KUBENETESUI_URL/$imageName
docker tag $ALIYUN_KUBENETESUI_URL/$imageName $KUBENETESUI_URL/$imageName
docker rmi $ALIYUN_KUBENETESUI_URL/$imageName
done
# show images
docker images
- 再去看 Docker Desktop 中已经启动 k8s 了，耐心一点，这个时间比较长，验证一下，发现 Server Version 出现了证明服务器安装成功，且客户端可以连接上
# kubectl version
Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.4", GitCommit:"d360454c9bcd1634cf4cc52d1867af5491dc9c5f", GitTreeState:"clean", BuildDate:"2020-11-12T01:09:16Z", GoVersion:"go1.15.4", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.3", GitCommit:"1e11e4a2108024935ecfcb2912226cedeafd99df", GitTreeState:"clean", BuildDate:"2020-10-14T12:41:49Z", GoVersion:"go1.15.2", Compiler:"gc", Platform:"linux/amd64"}
- 启用 k8s dashboard，需要调用一个 yaml
# kubectl apply -f k8s-dashboard.yaml
namespace/kubernetes-dashboard created
serviceaccount/kubernetes-dashboard created
service/kubernetes-dashboard created
secret/kubernetes-dashboard-certs created
secret/kubernetes-dashboard-csrf created
secret/kubernetes-dashboard-key-holder created
configmap/kubernetes-dashboard-settings created
role.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrole.rbac.authorization.k8s.io/kubernetes-dashboard created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
clusterrolebinding.rbac.authorization.k8s.io/kubernetes-dashboard created
deployment.apps/kubernetes-dashboard created
service/dashboard-metrics-scraper created
deployment.apps/dashboard-metrics-scraper created
# kubectl proxy
Starting to serve on 127.0.0.1:8001
- 启动成功后，打开浏览器，就可以登陆 Dashboard 要么证书登陆，要么 token 登陆，先执行：
TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}')
kubectl config set-credentials docker-desktop --token="${TOKEN}"
echo $TOKEN
显示的内容就是 token
- 证书登陆时，选择 ～/.kube/config
- token 登陆就是上面那串
K8S 仪表板
K8S 登陆成功
登陆成功后
安装 ThingsBoard 到 k8s
安装 ThingsBoard
根据官方文档，照着执行就好：https://github.com/thingsboard/thingsboard/tree/master/k8s
- 保证网络畅通，因为需要从 docker hub 下载 images，建议用国内的镜像地址
- 过程比较麻烦，不好监控，只能不停的刷 docker images 命令查看是不是把镜像拉下来了

好多个 container 在跑，好壮观
这时，你以为可以成功访问 ThingsBoard 主页吗？不行，真的不行，因为还差一个步骤，非常重要，那就是你的机器还没有 ingress ，建议你去好好读一读这个知识点。
安装 Ingress Nginx
- 直接去官方网站看文档，照着执行，但是你需要科学上网：https://github.com/kubernetes/ingress-nginx/blob/master/docs/deploy/index.md
# kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.41.2/deploy/static/provider/cloud/deploy.yaml
想办法把这个文件搞下来，因为这是部署 Ingress Nginx 的配置文件
我提供一个备份： ingress-nginx.yaml，启动：
# kubectl apply -f ingress-nginx.yaml
namespace/ingress-nginx unchanged
serviceaccount/ingress-nginx unchanged
configmap/ingress-nginx-controller configured
clusterrole.rbac.authorization.k8s.io/ingress-nginx unchanged
clusterrolebinding.rbac.authorization.k8s.io/ingress-nginx unchanged
role.rbac.authorization.k8s.io/ingress-nginx unchanged
rolebinding.rbac.authorization.k8s.io/ingress-nginx unchanged
service/ingress-nginx-controller-admission unchanged
service/ingress-nginx-controller unchanged
deployment.apps/ingress-nginx-controller configured
validatingwebhookconfiguration.admissionregistration.k8s.io/ingress-nginx-admission configured
serviceaccount/ingress-nginx-admission unchanged
clusterrole.rbac.authorization.k8s.io/ingress-nginx-admission unchanged
clusterrolebinding.rbac.authorization.k8s.io/ingress-nginx-admission unchanged
role.rbac.authorization.k8s.io/ingress-nginx-admission unchanged
rolebinding.rbac.authorization.k8s.io/ingress-nginx-admission unchanged
job.batch/ingress-nginx-admission-create unchanged
job.batch/ingress-nginx-admission-patch unchanged
- 下载 ingress-nginx 镜像
# docker pull k8s.gcr.io/ingress-nginx/controller:v0.41.2@sha256:1f4f402b9c14f3ae92b11ada1dfe9893a88f0faeb0b2f4b903e2c67a0c3bf0de
因为系统提示，这个镜像无法下载，或这很慢，你需要手动执行。看看有没有成功：
# kubectl get pods -n ingress-nginx -l app.kubernetes.io/name=ingress-nginx --watch
NAME READY STATUS RESTARTS AGE
ingress-nginx-admission-create-sd5zj 0/1 Completed 0 16m
ingress-nginx-admission-patch-pfjhp 0/1 Completed 2 16m
ingress-nginx-controller-c4f944d4d-wcqxv 0/1 Running 0 16m
ingress-nginx-controller-c4f944d4d-wcqxv 1/1 Running 0 16m
- 查看本地是否已经成功监听 80 和 443 端口，如果存在，那就是跑通了
netstat -na |grep LIST
tcp46 0 0 *.1883 *.* LISTEN
tcp46 0 0 *.443 *.* LISTEN
tcp46 0 0 *.80 *.* LISTEN
查看 k8s dashboard 状态
ThingsBoard 登陆界面，出现太重要了
成功登陆，且新建租户正常
建议
最后，不建议在本地跑 k8s，速度太慢了，不如跑 jar 来的方便，调试起来也不方便。开发环境用 mvn spring-boot:run，测试环境直接部署在 CentOS 或 Ubuntu 环境单机跑足够用了，大量数据采集，访问用户数量大，才可以试试 k8s 环境，欢迎大家留言讨论！
