I'm trying to run a simple Docker image with Apache and a PHP program. It works fine if I run
docker run -t -i -p 80:80 my/httpd /bin/bash
then manually start Apache
service httpd start
however I cant get httpd to start automatically when running
docker run -d -p 80:80 my/httpd
Apache will startup then container exists. I have tried a bunch of different CMD
s in my docker file
CMD /etc/init.d/httpd start
CMD ["service" "httpd" "start"]
CMD ["/bin/bash", "/etc/init.d/httpd start"]
ENTRYPOINT /etc/init.d/httpd CMD start
CMD ./start.sh
start.sh is
#!/bin/bash
/etc/init.d/httpd start
However every-time docker instance will exist after apache starts
Am I missing something really obvious?
You need to run apache (httpd) directly - you should not use init.d script.
Two options:
/usr/sbin/apache2 -DFOREGROUND ...
(or /usr/sbin/httpd in CentOS)/sbin/init
as entrypoint.将此行添加到Dockerfile
的底部以在 CentOS 的前台运行 Apache
ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]
Simple Dockerfile to run httpd on centOS
FROM centos:latest
RUN yum update -y
RUN yum install httpd -y
ENTRYPOINT ["/usr/sbin/httpd","-D","FOREGROUND"]
Commands for building images and running container
Build
docker build . -t chttpd:latest
Running container using new image
docker container run -d -p 8000:80 chttpd:latest
In the end of Dockerfile, insert below command to start httpd
# Start httpd
ENTRYPOINT ["/usr/sbin/httpd", "-D", "FOREGROUND"]
This works for me
ENTRYPOINT /usr/sbin/httpd -D start && /bin/bash
