Repo with Dockerfile & docker-compose.ymp - https://github.com/AlexMercedCoder/ez-developer-environment⁠

Developer Environment with Docker

The Dockerfile and docker-compose.yml are meant to help create an easy to replicate and portable developer environment with the following languages.

• Keep in mind the initial building of the dockerfile will take awhile

Through the Dockerfile based image

• Javascript through node & deno
• Java 17
• Scala 2 & 3 using Coursier (sbt is installed)
• Python 3 (via python3 command)
• Ruby
• PHP

Docker Compose file will also include

• postgres database being serves on port 5432
• mongodb database beign served on

Building just the image

Make sure to edit the command below with your gitusername and email

Build Command

docker build -my_dev_environ --build-arg gitusername="Your Name" --build-arg gitemail="Your@email.com" .

docker run -it my_dev_environ

Setting up the environment using Docker-Compose

First make sure to enter your username and the email on your github account in the env variables.

      args:
        gitusername: "Your Name"
        gitemail: "your@email.com"

Then to turn on the environment (include mongo and postgres databases)

docker-compose up

To turn off the environment

docker-compose down

Opening Up in VSCode

• download the remote-containers vscode extension
• once the container is running
• open the command-pallette and select "Remote-Containers: Attach to Running Container"
• You should be able to attach vscode to the running container and work from it

another option is to copy the dockerfile and docker-compose.yml to a new directory you want to work out of and select "Remote-Containers: Open folder in a container" it should detect the files and give you the option of opening using either. Select the dockerfile or select docker-compose.yml and select the languages service.

Running Individual Services

If you want to turn on the services individually incase you don't need all three:

• 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

Running Single Commands

If you just wanted to run a single command against a container, follow this example where we run bash in the languages container.

docker-container run languages /bin/bash/
