docker-compose的yml文件配置deploy参数失效use the ‘deploy‘ key, which will be ignored.

 1.遇到问题配置deploy失效

报错:Some services (hsb_mq_bid) use the 'deploy' key, which will be ignored. Compose does not support 'deploy' configuration - use `docker stack deploy` to deploy to a swarm.

在yml中配置replicas启动,然后打印日志查看发现,实例只启动了一个

[root@node1 hsb_yaml]# docker-compose logs -f

2.解决办法

查询资料得知,Swarm集群不支持在yml中配置replicas,具体操作如下

# 如果需要在 Swarm 集群中部署：
# 先初始化集群
docker swarm init
# 执行操作
docker stack deploy -c docker-compose.yml hsb_cookies

查看日志

# 查看日志
docker service logs -f hsb_cookies_hsb_mq_bid

[root@node1 hsb_yaml]# docker service logs -f hsb_cookies_hsb_mq_bid

可以看到实例化已经正常,启动个数和yml配置个数相同

如果你需要同时支持单机和 Swarm 模式，可以将 deploy 保留在文件中，但通过不同的命令区分：
单机：docker-compose up（忽略 deploy）
Swarm：docker stack deploy（使用 deploy）
