启动docker镜像报错

[ciwei12]

宿主机版本为CentOS Linux release 7.1.1503 (Core)
用dockerfile build 了一个带有Apache的镜像
镜像系统为Ubuntu 14.04
以下为dockerfile内容

FROM sshd:ubuntu
MAINTAINER chaucer
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get -yq install apache2&&\

run.sh内容
#!/bin/bash
exec apache2 -D FOREGROUND


镜像已build成功
[root@localhost apache_ubuntu]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
apache ubuntu 6cee2e39ea13 9 hours ago 269 MB

但在启动镜像时报错
[root@localhost apache_ubuntu]# docker run -d -P apache:ubuntu
6e2ec3d9c75ac25971944c39d05dc90cd0770f73beb85f17ea5b2d86ec897e08
/usr/bin/docker-current: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"exec: \\\"run.sh\\\": executable file not found in $PATH\"\n".

请问哪位大神知道原因？

感觉像 run.sh的问题，可以进入到镜像里面，然后在里面执行run.sh 看看能否执行成功

[ciwei12]

进入镜像运行run.sh 报错 root@f31f3c76b4da:/# ./run.sh AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message 网上查了一下应该在/etc/apache2/apache2.con最后一行加这句 ServerName localhost:80 修改以后再运行run.sh没有任何输出 退出再次启动容器，成功

重启docker就行了
