docker-compose 中启动nacos和seata，nacos仅仅作为seata的注册中心，启动抛异常

[orange-form]

• I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

下面是我的docker-compose 文件。
version: '3.2'

services:
nacos:
image: nacos/nacos-server:latest
container_name: nacos-standalone
environment:
- PREFER_HOST_MODE=hostname
- MODE=standalone
volumes:
- ./logs/nacos/:/home/nacos/logs
- ./data/nacos/:/home/nacos/data
ports:
- "8848:8848"
networks:
- zz-test

seata-server:
image: seataio/seata-server:1.2.0
hostname: seata-server
ports:
- "8091:8091"
environment:
- SEATA_PORT=8091
- STORE_MODE=file
- SEATA_CONFIG_NAME=file:/root/seata-config/registry
- SEATA_IP=localhost
volumes:
- ./services/seata/:/root/seata-config
- ./logs/seata:/root/logs
links:
- nacos
depends_on:
- nacos
networks:
- zz-test

networks:
zz-test:
driver: bridge

下面是registry.conf

registry {
type = "nacos"

nacos {
application = "my-seata-server"
serverAddr = "nacos"
namespace = ""
cluster = "default"
username = ""
password = ""
}
}

config {
type = "file"

file {
name = "file:/root/seata-config/file.conf"
}
}

附件文件seata-startup-exception.txt是seata启动抛出的异常。
naming.log是nacos的日志。
BTW，这些配置的缩进都是正确的，只是提交issue之后的显示问题。
seata-startup-exception.txt
naming.log

username = ""
password = ""
应该是nacos 1.2.0的权限控制

[orange-form]

@zjinlei 已经改为下面的应用配置了还是不行。另外，相同的配置如果我不用docker，而是命令行启动，注册nacos是没有问题的。
nacos {
application = "my-seata-server"
serverAddr = "nacos"
namespace = ""
cluster = "default"
username = "nacos"
password = "nacos"
}

[cmonkey]

看日志，看起来是你网络配置的问题，serverAddr = "nacos", nacos 这个别名在容器里面有指向一个具体的ip 吗？

[orange-form]

@cmonkey
没有指向具体的ip，但是我在docker-compose中，用links引用了nacos 容器了。举个例子，我把seata的服务中心改为file，这样就能docker启动了，然后我进入docker容器，是可以ping到nacos这个服务名的。

@orange-form
seata启动的时候 nacos 启动没有完成，注册失败后直接关闭了，需要等nacos启动完成后再启动

version: '2.1'

services:
  nacos:
    image: nacos/nacos-server:latest
    container_name: nacos-server
    healthcheck:
      test: curl localhost:8848/nacos
      interval: 10s
      timeout: 3s
      retries: 3
    environment:
      - PREFER_HOST_MODE=hostname
      - MODE=standalone
    ports:
      - "8848:8848"
    networks:
      - seata_network

  seata-server:
    image: seataio/seata-server:1.2.0
    container_name: seata-server
    hostname: seata-server
    ports:
      - "8091:8091"
    environment:
      - SEATA_PORT=8091
      - SEATA_CONFIG_NAME=file:/root/seata-config/registry
    volumes:
      - ./seata/:/root/seata-config
    links:
      - nacos
    depends_on:
      nacos:
        condition: service_healthy
    networks:
      - seata_network

networks:
  seata_network:
    driver: bridge

docker-compose 延迟启动参考 docker/compose#374

@helloworlde
非常感谢您的建议。我后来又仔细想了一下，确实如您所说。

[hermitcai]

害 就是启动先后顺序的问题了
