docker-compose image 段下载私有仓库（需要认证）中的镜像失败

[Kronos]

本人还在学习 docker 中，今天遇到一个问题，请大家帮我看一下下：
私有仓库搭建成功，能登陆，能下载上传

登陆：
[root@dockerma1 identidock]# docker login -u testuser -p testpassword registryv2:5043
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded

下载：
[root@dockerma1 identidock]# docker pull registryv2:5043/dnmonster:1.0
1.0: Pulling from dnmonster
.......

[root@dockerma1 identidock]# curl -u testuser:testpassword https://registryv2:5043/v2/_catalog
{"repositories":["busybox","dnmonster","identidock","redis"]}

用 docker pull 都成功拉取，但是一用 docker-compose 拉镜像就失败
[root@dockerma1 identidock]# docker-compose up -d
Creating identidock_dnmonster_1...
Pulling redis (registryv2:5043/redis:3.0)...

docker-compose.yml 文本内容:
[root@dockerma1 identidock]# cat docker-compose.yml
identidock:
image: registryv2:5043/identidock:1.0
ports:
- "5000:5000"
- "9000:9000"
environment:
ENV: DEV
links:
- dnmonster
- redis

dnmonster:
image: registryv2:5043/dnmonster:1.0

redis:
image: registryv2:5043/redis:3.0

请问 docker-compose 拉私有镜像要在 yml 里提供认证发式吗？还是我搭建认证的私有仓库有问题？（我就想用 docker-compose 来构建，不太想用 shell 脚本）
