Launching Tech Stack in order to Python, Flask Framework and MongoDB with Docker Compose. For this documentation, I have an interesting full article that I recommend you Python, Flask, MongoDB with Docker Compose.

First, making clone to this project, doing:

git clone https://github.com/jersonmartinez/Python-Flask-MongoDB-with-Docker-Compose.git

And then, execute the Docker Compose instruction to launch Tech Stack (Python, Flask and MongoDB).

docker-compose up -d

Update the file .env (environment variables) with your specify credentials.

WEB_HOST=cs_api

MONGO_HOST=cs_mongodb
MONGO_PORT=27017
MONGO_USER=root-crashell
MONGO_PASS=password-crashell
MONGO_DB=db_crashell

Other important file is mongo-init.js.

db.createUser(
    {
        user: 'root-crashell',
        pwd: 'password-crashell',
        roles: [
            { role: "clusterMonitor", db: "admin" },
            { role: "dbOwner", db: "db_name" },
            { role: 'readWrite', db: 'db_crashell' }
        ]
    }
)

This result is using the curl tool.

$ curl 127.0.0.1:8000
<h1 style="background-color: #262626; color: white; padding: 20px; text-align:center;">Hello, Crashell!</h1>

Result using the browser.

Execute the following instruction using curl or the browser.

$ curl 127.0.0.1:8000/api

"Connected to the MongoDB Server!"

Result using the browser.

We have two ways to remove our volumes with Docker.

First is using prune command.

docker volume prune -f

Second is using the current command volume rm with -f like parameter.

docker volume rm $(docker volume ls -q)

rm -rf mongo-volume app/__pycache__/ && mkdir mongo-volume

docker system prune -a -f && docker builder prune -a -f

docker-compose up --build --force-recreate --no-deps -d web

docker logs --tail 1000 -f cs_api
