Dockerfile for CentOS 7 with Apache and pyenv

This is a working dockerfile to use CentOS 7 with pyenv and Apache2 installed.

It's good to use this Docerfile to test some settings and manipulations similar to the cPanel's environment, for example. You are welcome to add MySQL/PostgreSQL or any other DB, RabbiMQ/Kafka, nGinx, etc.

Please, read full set of pyenv commands here: pyenv Commands

This Dockerfile, by default, exposes ports 80 and 8080. You can call it like this:

$ docker build -t pyenv_on_co7 .

Then: $ docker run -itd -p 8899:80 --rm --name=pyenv_on_co7 pyenv_on_co7 bash - if you want access to bash on the docker container.

A few tips for you.

• If you need expose ports to the local machine add -p 8899:80 command into the run, where 8899 is a port where you will be able to access to the container from your local machine, and 80 is a port in the container. So, if you opern a browser on your local machine and type http://localhost:8899/ you will see the output of the server inside the container.
• Use -v to add some volumes (read about volumes in the Docker manpages) to keep your data persistent even after you stop the container. You can use a few volumes: for system user files, for webserver files, for DB files, for configuration etc.
• you can detach the container, by the -d flag, so you will be able to close terminal and the container will be alive anyway. You can then enter it at anytime you want by $ docker attach pyenv_on_co7. But note: if you have no service, that remaining alive in the container it will not be alive. Your app must spin as a process to make the container alive. For this purpose I suppose you to have bash at the end of your run command, as this shell will be always alive.
• Use --detach-keys="ctrl-d" (set any combination you want) within attach command to specify the hotkey for detaching the container (instead of exiting it). So, the copmlete command will look like: $ docker attach --detach-keys="ctrl-d" pyenv_on_co7.
• Add --rm to autoremove container on exit to make the name available again.
• Do not forget to set a proper configuration in the /etc/httpd/conf/httpd.conf to make your server working.
• Commands for Starting/restarting/stopping the Apache2 server in the CentOS 7 is $ apachectl -k start, $ apachectl -k stop, $ apachectl -k restart.
