Seata Server in k8s

1.部署 seata-server

1.创建seata-server需要的表
具体的 SQL 参考 https://github.com/seata/seata/tree/develop/script/server/db，这里使用的是 MySQL 的脚本，数据库名称为 seata
同时，也需要创建 undo_log 表， 可以参考 https://github.com/seata/seata/tree/develop/script/client/at/db
2.修改seata-server配置
将以下配置添加到 Nacos 配置中心，具体添加方法可以参考 https://github.com/seata/seata/tree/develop/script/config-center
[root@k8s-matser01 ~]# cat config.txt 
ervice.vgroupMapping.my_test_tx_group=default
store.mode=db
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://10.2.1.12:30060/seata?useUnicode=true  # 数据库地址
store.db.user=root # seata数据库的账号
store.db.password=123456 # seata数据库的密码
[root@k8s-matser01 ~]# sh ./nacos/nacos-config.sh -h 10.2.1.12 -p 8848 -g SEATA_GROUP -u nacos -w nacos
参数说明:

-h: Nacos主机地址，默认是localhost

-p: Nacos主机端口，默认是8848

-g: 配置分组, the default value is 'SEATA_GROUP'.

-t: 租户信息, 与Nacos的 "命名空间ID" 字段相对应, the default value is ''.

-u: Nacos用户名, the default value is ''.

-w: Nacos密码, the default value is ''.

[root@k8s-matser01 nacos]# cat nacos-config.sh  
...
   100	count=0
    # 我这里改成了绝对路径
   101	for line in $(cat /root/nacos/config.txt | sed s/[[:space:]]//g); do
   102	    count=`expr $count + 1`
   103		key=${line%%=*}
   104	    value=${line#*=}
···

2.部署 seata-server 到 Kubernetes

[root@k8s-matser01 ~]# cat seata.yaml 
apiVersion: v1
kind: Service
metadata:
  name: seata-ha-server
  namespace: default
  labels:
    app.kubernetes.io/name: seata-ha-server

  ports:
    - port: 8091
      protocol: TCP
      name: http
  selector:
    app.kubernetes.io/name: seata-ha-server

apiVersion: apps/v1

  namespace: default

          env:
            - name: SEATA_CONFIG_NAME
              value: file:/root/seata-config/registry
          ports:
            - name: http
              containerPort: 8091
              protocol: TCP
          volumeMounts:
            - name: seata-config
              mountPath: /root/seata-config
      volumes:
        - name: seata-config
          configMap:
            name: seata-ha-server-config


---
apiVersion: v1
kind: ConfigMap
metadata:
  name: seata-ha-server-config
data:
  registry.conf: |
    registry {
        type = "nacos"
        nacos {
          application = "seata-server"
          serverAddr = "10.2.1.12" #nacos的ip
        }
    }
    config {
      type = "nacos"
      nacos {
        serverAddr = "10.2.1.12" # nacos的ip
        group = "SEATA_GROUP"
      }
    }

3.问题

# 这是我用的最新的seata镜像,换成了seata:1.3.0就ok了，百度说了是jdk的问题
