Redis docker starts/restarts 多次？
Redis in docker starts/restarts multiple times?
我正在尝试 运行 使用 docker 容器中的 redis docker-compose:
docker-compose.yml:
redis:
image: redis:3.0.4
命令：
$ docker-compose up
输出：

出于某种原因，redis 启动多次，有时只启动一次（这是随机的）。在日志中有很多喜欢：
redis_1 | 1:signal-handler (1444144597) Received SIGTERM scheduling shutdown...
环境：
docker-compose version: 1.4.0
Docker version 1.8.0, build 0d03096
docker-machine version 0.4.0 (9d0dc7a)
edit：只有在使用 docker-compose 时才会发生。虽然 运行ning redis 与 docker run redis:304 它工作正常。
这里讨论了类似的问题：https://github.com/docker/compose/issues/2148
将 --force-recreate 添加到 docker-compose 命令似乎可以阻止它。
