Docker provides a way to run applications isolated in containers. Working with Docker is a really easy and useful habbit, as a developer you should always aim for the best practices and tools. A portable and flexible virtual environment is a powerful tool to encapsulate your application or quickly start an other experiment without overcomlicated development/production server architecture.
Docker is the company driving the container movement and the only container platform provider to address every application across the hybrid cloud. Today’s businesses are under pressure to digitally transform but are constrained by existing applications and infrastructure while rationalizing and increasingly diverse portfolio of clouds, datacenters and application architectures. Docker enables true independence between applications and infrastructure and developers and IT ops to unlock their potential and creates a model for better collaboration and innovation.
No mather what is your host system, you can install Docker and you can run any container in your environment, you can run a Linux container on a Windows and inside there you can run multiple services for your development. For installing follow the instructions on the following pages:
Documentation about installation: https://docs.docker.com/engine/installation
After you installed docker you should able to run docker and docker-compose
in your terminal/command line tool. For quickly boot up a project you will need
to create one file in your project root folder: docker-compose.yml with this
basic configuration:
version: '3.4'
services:
web:
image: phpearth/php:7.2-apache
volumes:
- ./:/var/www/localhost/htdocs
ports:
- 8080:80
For running it open your project folder in command line and call: docker-compose up
It will download the group image and start your server, it will link your project folder with the default server root and it will bound the server http output to your machine :8080 port.
After it’s started check your http://localhost:8080 url and you should able to start develop your project.
Note: You should bound a
srcfolder into the container instead the whole project by replacing the./to./src
For more options check the documentation: https://docs.docker.com/compose/compose-file
