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,seata-namingserver,jars}
cd /Docker/Seata

 

4、从镜像提取 resources 和 libs

docker create --name seata-tmp apache/seata-server:2.6.0
docker cp seata-tmp:/seata-server/resources seata-server/
docker cp seata-tmp:/seata-server/libs        seata-server/
docker rm seata-tmp

docker create --name ns-tmp apache/seata-naming-server:2.6.0.jdk25
docker cp ns-tmp:/seata-naming-server/resources/application.yml seata-namingserver/
docker rm ns-tmp

 

5、修改 seata-server/resources/application.yml配置文件

6、修改 seata-namingserver/application.yml配置文件

7、改造 seata-server/libs

cd /Docker/Seata/seata-server/libs

# ===== 改动 1：移出老 nacos-client（移到 jars/ 备份，别改名留在原地） =====
mv nacos-client-1.4.6.jar /Docker/Seata/jars/

# ===== 改动 2：放入 nacos-client 2.0.4 + 它的两个依赖 =====
# （Seata 2.6.0 自带的 1.4.6 只会调 Nacos v1 HTTP API，而 Nacos 3.x 彻底删除了 v1 API）
wget https://repo1.maven.org/maven2/com/alibaba/nacos/nacos-client/2.0.4/nacos-client-2.0.4.jar
wget https://repo1.maven.org/maven2/org/reflections/reflections/0.9.11/reflections-0.9.11.jar
wget https://repo1.maven.org/maven2/org/javassist/javassist/3.29.2-GA/javassist-3.29.2-GA.jar

# ===== 改动 3：放入 MySQL 驱动（放 libs 根目录！） =====
wget https://repo1.maven.org/maven2/com/mysql/mysql-connector-j/8.0.33/mysql-connector-j-8.0.33.jar

# ===== 确认 =====
ls -lh nacos-client* reflections* javassist* mysql-connector*
# nacos-client-2.0.4 约 14MB（gRPC+protobuf 打包在内，大是正常的）
# reflections 约 130KB，javassist 约 500KB，mysql-connector-j 约 2.4MB

 

8、修改docker-compose.yml文件

services:
  seata-namingserver:
    image: apache/seata-naming-server:2.6.0.jdk25
    container_name: seata-namingserver
    environment:
      - TZ=Asia/Shanghai
    ports:
      - "8081:8081"    # Web Console + MCP（/mcp）
    volumes:
      # 冒号左边是宿主机目录名（我们自己起的，与原生安装命名一致），
      # 右边是镜像内置的容器内路径 /seata-naming-server/...（改不了，照抄）
      - ./Seata/seata-namingserver/application.yml:/seata-naming-server/resources/application.yml
    restart: always
    networks:
      - timeless

  # ==================== seata-server（TC 主程序） ====================
  seata-server:
    image: apache/seata-server:2.6.0
    container_name: seata-server
    environment:
      - SEATA_IP=192.168.20.140       # ★★ 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
      - STORE_MODE=db
      - TZ=Asia/Shanghai
    ports:
      - "8091:8091"    # TC 事务端口（TM/RM 客户端连这个）
    volumes:
      - ./Seata/seata-server/resources:/seata-server/resources   # 配置（4.3 改好的）
      - ./Seata/seata-server/libs:/seata-server/libs             # 依赖（4.5 改好的）
    depends_on:                        # ★ 只管同 compose 内的 namingserver
      seata-namingserver:
        condition: service_started     # jib 镜像无健康检查，只等"启动"
    restart: on-failure                # ★★ 主力：Nacos 跨 compose 没法 depends_on，靠失败重试兜底
    networks:
      - timeless

networks:
  timeless:
    name: timeless
    driver: bridge
