无法在 docker 镜像中启动 httpd 服务

  • 772

我有以下应该启动 centos 机器并安装 httpd 的 Dockerfile：

FROM centos:centos6.6
RUN yum install -y httpd
RUN chkconfig httpd on; 
RUN /etc/init.d/httpd start
EXPOSE 80

CMD ["/bin/bash"]

我构建图像：

docker build --no-cache -t centos_http .

构建说：

...
Step 4/6 : RUN /etc/init.d/httpd start
---> Running in 0766e84ec292
Starting httpd: httpd: Could not reliably determine the server's fully  qualified domain name, using 172.17.0.2 for ServerName
[  OK  ]
...
Successfully built 5380a0bacdfb

但是如果我运行图像：

docker run  -p 8090:80 -it  5380
[root@eda7400a46a9 /]# ps -ef | grep httpd | grep -v grep
[root@eda7400a46a9 /]#

httpd 没有运行！如果我在图像内部手动执行 /etc/init.d/httpd start，它工作正常......

    你做错了。RUN命令将仅在构建期间执行。你应该使用类似下面的东西

    FROM centos:6.6

RUN yum install -y httpd

EXPOSE 80

ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]

    你也可以看看官方的 apache Dockerfile
