docker和k8s部署seata-server 配置nacos

1、编写docker-compose.yaml文件

version: "3"
services:
  seata-server:
    image: seataio/seata-server:1.4.2
    hostname: seata-server
    container_name: seata-server
    ports:
      - "8091:8091"
    volumes:
      - ./seata-server:/seata-server
    environment:
      - SEATA_PORT=8091
      - STORE_MODE=file

2、将挂载目录注释后启动

docker-compose up -d

3、将容器镜像里的配置拷贝出来

docker cp seata-server:/seata-server ./seata-server

4、停止容器并修改seata-server/resources/registry.conf配置文件

停止容器

docker-compose down

文件修改

修改为type="nacos"，并填上正确的nacos地址

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "ip:8848"
    group = ""
    namespace = ""
    cluster = "default"
    username = ""
    password = ""
  }

5、nacos添加seata-serveer配置文件

seata.yaml

client:
  rm:
    asyncCommitBufferLimit: 10000
    reportRetryCount: 5
    reportSuccessEnable: false

 6、docker-compose ip -d启动

7、在nacos上查看服务列表

 1、制作镜像并上传到harbor

Dockerfile

FROM seataio/seata-server:1.4.2
ADD registry.conf  /seata-server/resources/registry.conf

docker build -t xxx/seata-server:k8sv1.4.2 .
docker push  xxx/seata-server:k8sv1.4.2

2、编写k8s yaml文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: seata-server #应用名称
  namespace: mbo
  labels:
    app: seata-server
    mbo: seata-server
spec:
  selector:
    matchLabels:
      app: seata-server
  replicas: 1 #开启实例份数
  template:
    metadata:
      labels:
        app: seata-server
        mbo: seata-server
    spec:
      imagePullSecrets:
        - name: docker-pull-images
      containers:
        - name: seata-server  #容器名称
          image: xxx/seata-server:k8sv1.4.2                
          imagePullPolicy: Always 
          ports:
            - name: http
              containerPort: 8091       
          #readinessProbe就绪探测，用于判断容器是否启动完成
          readinessProbe:
            tcpSocket:
              port: 8091
            initialDelaySeconds: 5
            periodSeconds: 10
          #存活探测，用于判断容器是否存活（running状态）
          livenessProbe:
            tcpSocket:
              port: 8091
            initialDelaySeconds: 15
            periodSeconds: 20                

---
    
kind: Service
apiVersion: v1 
metadata:
  name: seata-server-svc #服务名称
  namespace: mbo
spec:
  type: ClusterIP
  selector:
    app: seata-server #应用名称
  ports:
    - name: seata-server-svc
      protocol: TCP
      port: 8091
      targetPort: 8091              

3、启动并查看日志
kubectl apply -f seata-server.yaml
kubectl get pods -nmbo|grep seata-server
kubectl logs seata-server-665cd7bfdf-f9nbc -nmbo
