创建 Deployment 文件

deploymemt.yaml

namespace：指定命名空间
image：使用 1.5.2 版本的镜像
ports：暴露 8091 和 7091 端口
volumeMounts：容器中的存储
mountPath：存储路径
subPath：指定出具体文件
volumes：pod 存储
configMap.name：对应 configMap 文件的 metadata. name

apiVersion: apps/v1
kind: Deployment
metadata:
  name: seata-server
  namespace: common
  labels:
    k8s-app: seata-server
spec:
  replicas: 1
  selector:
    matchLabels:
      k8s-app: seata-server
  template:
    metadata:
      labels:
        k8s-app: seata-server
    spec:
      containers:
        - name: seata-server
          image: docker.io/seataio/seata-server:1.5.2
          imagePullPolicy: IfNotPresent
          ports:
            - name: http-7091
              containerPort: 7091
              protocol: TCP
            - name: http-8091
              containerPort: 8091
              protocol: TCP
          volumeMounts:
            - name: seata-config
              mountPath: /seata-server/resources/application.yml
              subPath: application.yml
      volumes:
        - name: seata-config
          configMap:
            name: seata-server-config

创建 ConfigMap 文件

configmap.yaml
映射 application.yml 文件，例子使用 seata 原始配置文件

apiVersion: v1
kind: ConfigMap
metadata:
  name: seata-server-config
  namespace: common
data:
  application.yml: |
    server:
      port: 7091

    spring:
      application:
        name: seata-server

    logging:
      config: classpath:logback-spring.xml
      file:
        path: ${user.home}/logs/seata
      extend:
        logstash-appender:
          destination: 127.0.0.1:4560
        kafka-appender:
          bootstrap-servers: 127.0.0.1:9092
          topic: logback_to_logstash

    console:
      user:
        username: seata
        password: seata

    seata:
      config:
        # support: nacos, consul, apollo, zk, etcd3
        type: file
      registry:
        # support: nacos, eureka, redis, zk, consul, etcd3, sofa
        type: file
      store:
        # support: file 、 db 、 redis
        mode: file
    #  server:
    #    service-port: 8091 #If not configured, the default is '${server.port} + 1000'
      security:
        secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
        tokenValidityInMilliseconds: 1800000
        ignore:
          urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

创建 Service 文件

service.yaml
对外暴露 NodePort 端口

apiVersion: v1
kind: Service
metadata:
  name: seata-server
  namespace: common
  labels:
    k8s-app: seata-server
spec:
  type: NodePort
  ports:
    - port: 8091
      nodePort: 30893
      protocol: TCP
      name: seata-8091
    - port: 7091
      nodePort: 30793
      protocol: TCP
      name: seata-7091
  selector:
    k8s-app: seata-server

运行

kubectl apply -f deployment.yaml
kubectl apply -f configmap.yaml
kubectl apply -f service.yaml

访问

访问 ip:30793 即可访问 seata
默认账号：seata
默认密码：seata

高可用部署

修改 configmap 映射的 application.yml 文件

seata.config：配置 seata 配置文件路径
seata.registry：配置 seata 注册地址

seata:
  config:
    type: nacos
    nacos:
      server-addr: nacosIp:port
      namespace: seata
      group: dev
      username: nacos
      password: nacos
      data-id: seata-dev.yml
  registry:
    type: nacos
    nacos:
      application: seata-server
      server-addr: nacosIp:port
      group: dev
      namespace: seata
      cluster: default
      username: nacos
      password: nacos
