问题

遇到一个问题,我自己用Dockerfile创建了一个nginxphp-fpm一体的镜像,但是使用docker run加上一些参数可以正常启动,但是使用docker-compose配置成服务却无法正常启动,这就很奇怪了,于是,Google了一番,找到了解决办法。

以下是我的Dockerfile

原因

找了半天才发现是我的配置文件少写了配置
原来:
Docker镜像的缺省命令是bash,如果不加 -itbash命令执行了自动会退出,加-itdocker命令会为容器分配一个伪终端,并接管其stdin/stdout支持交互操作,这时候bash命令不会自动退出
像不使用docker-compose,我们会执行类似如下的命令
docker run -d -it mmm /bin/bash
docker-compose需要额外配置下
需要在docker-compose.yml中包含以下行:

1
2
stdin_open: true
tty: true

第一个对应于docker run中的 -i ,第二个对应于 -t .

修改完的docker-compose.yaml
