1、假设所有容器都在Docker下。

2、Seata的目录在Docker/Seata路径下。

3、创建目录结构

mkdir -p /Docker/Seata/{seata-server,jars}
cd /Docker/Seata

 

4、从镜像提取 resources 和 libs

# ★ cp 目标写的是父目录 seata-server/（不是 seata-server/resources）：
#   docker cp 会把源目录整个拷到目标目录"里面"——目标若写成已存在的
#   seata-server/resources，就会得到 seata-server/resources/resources，多套一层！
docker create --name seata-tmp apache/seata-server:2.2.0
docker cp seata-tmp:/seata-server/resources seata-server/
docker cp seata-tmp:/seata-server/libs        seata-server/
docker rm seata-tmp

 

5、添加缺少的驱动

cd /Docker/Seata/seata-server/libs
wget https://repo1.maven.org/maven2/com/mysql/mysql-connector-j/8.0.33/mysql-connector-j-8.0.33.jar

 

6、修改 seata-server/resources/application.yml

  seata-server:
    depends_on:
      nacos:
        condition: service_started
    image: apache/seata-server:2.2.0
    container_name: seata-server
    environment:
      - SEATA_IP=192.168.20.139       # ★★ 最容易踩的坑，见下方说明
      - SEATA_PORT=8091               # 遗留写法，2.x 实际不生效（端口由 yaml 的
                                     #   seata.server.service-port 决定），删掉也无影响

    restart: on-failure                # ★★ Nacos 跨 compose 没法 depends_on，靠失败重试兜底
    networks:
      - timeless                       # ★ 换成 139 上 Nacos 的实际网络名

networks:
  timeless:
    name: timeless
