Creating a Consistent Developer Environment with Docker

VIDEO OVERVIEW OF USING DOCKER IMAGE FROM DOCKER HUB

Repo with Docker/docker-compose.yml

Your Dev Environment

Maybe you got a new computer or you have decided to learn programming, either way you'll need to curate your development environment which means installing all the languages, tools and so forth all which can be tedious and require trouble shooting.

I'm here to tell you how you can make life a lot easier for yourself. Instead of installing dozens of tools, just install two things:

• Docker

• Visual Studio Code

• OPTIONAL: Git-Bash (so you have git on windows, git should be out of the box for Mac/Linux)

So google how to install these for your operating system and then we can continue!

Spinning up our containers

First step is to clone the following git repository anywhere on your computer so open up terminal/git-bash in a folder you want to work out of (I usually have a folder called development I do all my dev work in) then run the following command:

git clone https://github.com/AlexMercedCoder/ez-developer-environment.git

This will copy several files:

• Dockerfile: This will create our the image of environment

• docker-compose.yml: This can spin up our environment along with a postgres and mongodb database we can access.

We want to make sure git within the images is configured to credit your github account when you commit so inside the docker-compose.yml make sure to update the follow lines with your name and email.

      args:
        gitusername: "Your Name"
        gitemail: "[e-mail]"

After that, run the following command then take a break and watch some netflix while the environment is built (the process will only be this long the first time as it installs everything).

docker-compose up

All the containers should be up and running, if you need to shut off all the containers you can use the command:

docker-compose down

If you want to turn them on/off individually

docker-compose up languages
docker-compose up postgres
docker-compose up mongodb

to turn off

docker-compose down languages
docker-compose down postgres
docker-compose down mongodb

Attaching to Visual Studio Code

Open up visual studio code to your development folder.

Then install the extension remote-containers.

Open up the Visual Studio Code command pallette (gear in bottom left)

Look for the "Remote-Containers: Attach to Running Container" command

It should let you select the languages container and you now have the ability to work from that container in VSCode like you normally would on your computer.

If the languages container isn't showing up it may not be on. In a separate terminal just open it up with the command below then try again to attach VSCode.

docker-compose run languages /bin/bash/

Keep in mind all docker commands should be done in same folder at docker-compose.yml

That's it, you now have PHP, Java, Ruby, Node, Deno, Python all available for you to work in without having to install and configure each individually.
