Please refer to the [full article](https://tech.osteel.me/posts/docker-for-local-web-development-part-1-a-basic-lemp-stack "Docker for local web development, part 1: a basic LEMP stack") for a detailed explanation. 6 | 7 | ## Content 8 | 9 | This branch contains a basic LEMP stack running on Docker and orchestrated by Docker Compose, including: 10 | 11 | * A container for Nginx; 12 | * A container for PHP-FPM; 13 | * A container for MySQL; 14 | * A container for phpMyAdmin; 15 | * A volume to persist MySQL data. 16 | 17 | ## Prerequisites 18 | 19 | Make sure [Docker Desktop for Mac or PC](https://www.docker.com/products/docker-desktop) is installed and running, or head [over here](https://docs.docker.com/install/) if you are a Linux user. You will also need a terminal running [Git](https://git-scm.com/). 20 | 21 | This setup also uses localhost's port 80, so make sure it is available. 22 | 23 | ## Directions of use 24 | 25 | Add the following domain to your machine's `hosts` file: 26 | 27 | ``` 28 | 127.0.0.1 php.test 29 | ``` 30 | 31 | Clone the repository and change the current directory for the project's root: 32 | 33 | ``` 34 | $ git clone git@github.com:osteel/docker-tutorial.git 35 | $ cd docker-tutorial 36 | ``` 37 | 38 | Copy `.env.example` to `.env`: 39 | 40 | ``` 41 | $ cp .env.example .env 42 | ``` 43 | 44 | Run the following command: 45 | 46 | ``` 47 | $ docker compose up -d 48 | ``` 49 | 50 | This may take a little bit of time, as some Docker images might need downloading. 51 | 52 | Once the script is done, visit [php.test](http://php.test). 53 | 54 | ## Explanation 55 | 56 | The images used by the setup are listed and configured in [`docker-compose.yml`](https://github.com/osteel/docker-tutorial/blob/part-1/docker-compose.yml). 57 | 58 | When building and starting the containers based on the images for the first time, a MySQL database named `demo` is automatically created (you can pick a different name in the MySQL service's description in `docker-compose.yml`). 59 | 60 | A [minimalist Nginx configuration](https://github.com/osteel/docker-tutorial/blob/part-1/.docker/nginx/conf.d/php.conf) for the PHP application is also copied over to Nginx's container, making it available at [php.test](http://php.test). 61 | 62 | The `src/` directory containing the application is mounted onto both Nginx's and the application's containers, meaning any update to the code is immediately available upon refreshing the page, without having to rebuild any container. 63 | 64 | The database data is persisted in its own local directory through the volume `mysqldata`, which is mounted onto MySQL's container. A phpMyAdmin interface is available at [localhost:8080](http://localhost:8080) (the database credentials are root / root). 65 | 66 | Please refer to the [full article](https://tech.osteel.me/posts/docker-for-local-web-development-part-1-a-basic-lemp-stack "Docker for local web development, part 1: a basic LEMP stack") for a detailed explanation. 67 | 68 | ## Cleaning up 69 | 70 | To stop the containers: 71 | 72 | ``` 73 | $ docker compose stop 74 | ``` 75 | 76 | To destroy the containers: 77 | 78 | ``` 79 | $ docker compose down 80 | ``` 81 | 82 | To destroy the containers and the associated volumes: 83 | 84 | ``` 85 | $ docker compose down -v 86 | ``` 87 | 88 | To remove everything, including images and orphan containers: 89 | 90 | ``` 91 | $ docker compose down -v --rmi all --remove-orphans 92 | ``` 93 | --------------------------------------------------------------------------------
