六、从零实战企业级K8S本地部署ThingsBoard专业版集群-编程知识

1、从 docker hub 拉取 ThingsBoard PE 映像（所有节点）

1.1、查看k8s信息（主节点）

kubectl cluster-info       #查看k8s集群信息
kubectl get node           #查看节点信息
kubectl get pod -A         #查看内部组件

1.2、从 docker hub 拉取 ThingsBoard PE 映像（所有节点）

运行以下命令从 Docker 中心拉取映像。

docker pull thingsboard/tb-pe-node:3.6.3PE
docker pull thingsboard/tb-pe-web-report:3.6.3PE
docker pull thingsboard/tb-pe-web-ui:3.6.3PE
docker pull thingsboard/tb-pe-js-executor:3.6.3PE
docker pull thingsboard/tb-pe-http-transport:3.6.3PE
docker pull thingsboard/tb-pe-mqtt-transport:3.6.3PE
docker pull thingsboard/tb-pe-coap-transport:3.6.3PE
docker pull thingsboard/tb-pe-lwm2m-transport:3.6.3PE
docker pull thingsboard/tb-pe-snmp-transport:3.6.3PE

2、创建K8S集群PV存储库（主节点）

2.1、创建数据资源PV存储库：thingsboard-db-pv.yml

vi thingsboard-db-pv.yml

复制添加以下内容到thingsboard-db-pv.yml文件中：

#postgres
apiVersion: v1
kind: PersistentVolume
metadata:name: postgres-pv-claimnamespace: thingsboardlabels:app: postgrestype: local
spec:capacity:storage: 5GiaccessModes:- ReadWriteOncehostPath:path: /tmp/data/postgrespersistentVolumeReclaimPolicy: Recycle

metadata:name: cassandra-data-cassandra-2labels:type: localapp: cassandra
spec:capacity:storage: 8GiaccessModes:- ReadWriteOncehostPath:path: /tmp/data/cassandra-2persistentVolumeReclaimPolicy: Recycle

创建目录：

mkdir -p /tmp/data/postgres
mkdir -p /tmp/data/cassandra-0
mkdir -p /tmp/data/cassandra-1
mkdir -p /tmp/data/cassandra-2

2.2、创建第三方资源PV存储库：thingsboard-third-pv.yml

vi thingsboard-third-pv.yml

复制添加以下内容到thingsboard-third-pv.yml文件中：

#zookeeper
apiVersion: v1
kind: PersistentVolume
metadata:name: zookeeper-data-0labels:type: localapp: zookeeper
spec:capacity:storage: 100MiaccessModes:- ReadWriteOncehostPath:path: /tmp/data/zookeeper/data-0persistentVolumeReclaimPolicy: Recycle

#kafka
apiVersion: v1
