Nginx + PHP + Docker: How To Get PHP Page Up With Local Domain Name

I will setup a very simple php page with docker and nginx.

Source files can be found here:

https://github.com/ikknd/docker-study in folder recipe-02

1. Create a project folder setup:

• /var/www/docker-study.loc/recipe-02 

•     -> /docker 

•     -> /php

In "php" folder I will create index.php file that executes phpinfo().

2. Create nginx config site.conf in "docker" folder:

fastcgi_pass php:9000;

3. Edit /etc/hosts file on host machine, and add a record:

127.0.0.1       myapp.loc

4. Create docker-compose.yml file in "docker" folder:

Here I do several things:

• I use my own php.ini file, that I copy to php container, so if I need to change some settings, I simply do changes in php.ini and restart container
• If I do changes in php code in index.php file, there is no need to restart container, changes get applied immediately with browser page reload.
• "depends_on" - prevents container to start before other container, on which it depends

5. Go to /var/www/docker-study.loc/recipe-02/docker/ and execute:

docker-compose up -d

If I now try

myapp.loc/
