k8s 部署seata 1.5.0

1、配置依赖nacos的配置

1.1 创建命名空间

1.2 创建seata需要配置

前往seata github的仓库中，找到script/config-center/config.txt

修改配置，配置mysql模式：

#Transaction storage configuration, only for the server. The file, db, and redis configuration values are optional.
store.mode=db
store.lock.mode=db
store.session.mode=db
#Used for password encryption
store.publicKey=

#These configurations are required if the `store mode` is `db`. If `store.mode,store.lock.mode,store.session.mode` are not equal to `db`, you can remove the configuration block.
store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://mysql-brlm.newland:3306/seata?useUnicode=true&useSSL=true&rewriteBatchedStatements=true
store.db.user=seata
store.db.password=seata

2 部署seata

2.1 构建seata镜像

因为官方镜像的driverClassName不支持com.mysql.cj.jdbc.Driver，所以需要添加mysql8的jar支持。

1
2
[root@k8s-master01 seata1]# ls
Dockerfile  mysql-connector-java-8.0.30.jar

添加mysql8的jar支持，创建新的Dockerfile文件

1
2
FROM seataio/seata-server:1.5.0
COPY mysql-connector-java-8.0.30.jar /seata-server/libs

开始构建镜像

[root@k8s-master01 seata1]# nerdctl build -t docker.io/leellun/seata-server:1.5.0 -f ./Dockerfile  .
[root@k8s-master01 seata1]# nerdctl push docker.io/leellun/seata-server:1.5.0
