How can I run php-fpm in the default Docker container?

I have a Docker image -

FROM centos:7 MAINTAINER Me <me.me> RUN yum update -y RUN yum install -y git https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm RUN yum install -y ansible RUN git clone https://github.com/.../dockerAnsible.git RUN ansible-playbook dockerFileBootstrap.yml RUN (cd /lib/systemd/system/sysinit.target.wants/; for i in *; do [ $i == systemd-tmpfiles-setup.service ] || rm -f $i; done); \ rm -f /lib/systemd/system/multi-user.target.wants/*;\ rm -f /etc/systemd/system/*.wants/*;\ rm -f /lib/systemd/system/local-fs.target.wants/*; \ rm -f /lib/systemd/system/sockets.target.wants/*udev*; \ rm -f /lib/systemd/system/sockets.target.wants/*initctl*; \ rm -f /lib/systemd/system/basic.target.wants/*;\ rm -f /lib/systemd/system/anaconda.target.wants/*; VOLUME [ "/sys/fs/cgroup" ] EXPOSE 80 443 3306 CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]

Basically, I want php-fpm to start when the docker container starts. I have php-fpm if I manually go into the container and enable it with /usr/sbin/php-fpm .

I tried this inside my file with this command (this did not work). I also tried using the service module, but no luck.

  - name: Start php fpm command: /usr/sbin/php-fpm

How can I run php-fpm with apache?

You must use supervisor to run multiple services

In your docker file, install the dispatcher, then you run

 COPY ./docker/supervisord.conf /etc/supervisord.conf .... CMD ["/usr/bin/supervisord", "-n"]

And your docker/supervisord.conf contains all the services you want to run, so you can have something like this

 [program:php-fpm] command=/opt/remi/php70/root/usr/sbin/php-fpm -c /etc/php-fpm.conf ;command=/usr/sbin/php70-fpm -c /etc/php-fpm.d stdout_logfile=/dev/stdout stdout_logfile_maxbytes=0 stderr_logfile=/dev/stderr stderr_logfile_maxbytes=0 [program:nginx] command=/usr/sbin/nginx stdout_logfile=/dev/stdout stdout_logfile_maxbytes=0 stderr_logfile=/dev/stderr stderr_logfile_maxbytes=0

Of course, you should adapt to your php-fpm paths and versions and your services (nginx in my example, apache for you, etc.), but basically a supervisor is the best way to control the launch of several services from one starting point.

Here you can find the docker white paper on supervisor

https://docs.docker.com/engine/admin/using_supervisord/

I needed a similar thing again. For alpine Linux images, it was enough to run both php-fpm and the web server as a container command. Defined in Dockerfile somewhat like this:
 CMD /usr/bin/php-fpm -D; nginx

i.e. for daemonize php-fpm and then run nginx in the foreground.

In ubuntu / debian images, you must also enable the launch of recently installed packages by running the Dockerfile RUN command as follows:

 RUN echo "exit 0" > /usr/sbin/policy-rc.d

and then restart php-fpm inside php-fpm command

 CMD /etc/init.d/php7.0-fpm restart && nginx -g "daemon off;"

More information about policy-rc.d can be found in this askubuntu question.

I use rc.local to start services inside the container, and then run a command inside this container to execute rc.local. So, here is an example run command:

 sudo docker run --restart=always -itd --name mycontainer -p 80:80 -p 443:443 myimage/name /bin/bash -c "/etc/rc.local && while true; do echo hello world; sleep 100; done"

And this is one of the rc.local files from / etc

 #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. sleep 5 service mysql start sleep 5 service php5-fpm start sleep 5 service nginx start exit 0

What this means is to launch a container called mycontainer using the image "myimage / name" with open ports 80 and 443. After starting it, it calls mysql, php5-fpm and nginx to start, pausing between them for 5 seconds. Thus, you can call any service to start that you want to run inside this container. Remember to add open ports for these services.

This start command will also add “Hello World” to your log file every 100 seconds as a “boost”, which will let you know when it was started and when it was stopped.

I came here to see how to run php-fpm in the foreground so that it can be PID 1 in the docker container. Decision

 php-fpm -F -R

Explanation

We can check the available options with php-fpm --help

 -F, --nodaemonize force to stay in foreground, and ignore daemonize option from config file

If you use php-fpm in the php-fpm container, there is a good chance that you are running the process with root privileges. php-fpm does not start as root without an additional flag:

  -R, --allow-to-run-as-root Allow pool to run as root (disabled by default)

I believe that @ckeeney's answer above can be accepted as the correct answer, but I could not get it to work with my specific case.

use dumb-init

I managed to proxy PID1 via dumb-init and daemonize PHP-FPM with the following command: dumb-init /usr/sbin/php-fpm7.2 -F -R https://engineeringblog.yelp.com/2016/01/dumb- init-an-init-for-docker.html
