The most simple php 8, mysql 8, nginx docker setup.

README.md

Notes

• You can replace dockerproject with whatever project namespace you are using.
• Be sure to use same value for network in docker-compose.
• In docker-compose files are referenced in an existing directory docker.
  • Make sure to create these files inside docker directory on same level of docker-compose.yml file and replace - with subdirectory from this gist. For exmaple:
    • Create docker/nginx/dockerproject.conf file to use docker-nginx-dockerproject.conf.
• Make sure that the root path matches public directory of your framework/code that will serve the fronte page of application.
• Access mysql database on port 3307 assuming you might already have a local instance running at 3306.
• Access application in your browser at port 8001. You can change this under nginx section in docker-compose file.
