無法在 docker 映像中啟動 httpd 服務

無法在 docker 映像中啟動 httpd 服務

我有以下 Dockerfile，應該啟動 centos 機器並安裝 httpd：

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

CMD ["/bin/bash"]

我建構圖像：

docker build --no-cache -t centos_http .

建構說：

...
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

但如果我運行圖像：

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

httpd 沒有運作！如果我在圖像內手動執行 /etc/init.d/httpd start ，它工作正常......

你做的完全錯誤。RUN命令僅在建置期間執行。你應該使用類似下面的東西

FROM centos:6.6

RUN yum install -y httpd

EXPOSE 80

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

您也可以看看官方 apache Dockerfile
