Demo flask redis dockerized templates

Example of how to handle background processes with Flask, Redis Queue, and Docker

Quick Start

Spin up the containers:

$ docker-compose up --build -V --scale worker=4

Spin up the containers in background:

$ docker-compose up -d --build -V --scale worker=4

Stop all containers and workers:

$ docker-compose down -v

Open your browser to http://localhost:5004

Open redis dashboard in http://localhost:9181/

Show logs from worker containers:

docker-compose logs --tail=0 -f master
docker-compose logs --tail=0 -f worker

You can view a list of all the allocated volumes in your system with

docker volume ls

If you prefer a more automatic cleanup, the following command will remove any unused images or volumes, and any stopped containers that are still in the system.

docker system prune --volumes

Some important docker commands:

Below command will remove the following:

• all stopped containers
• all networks not used by at least one container
• all dangling images
• all dangling build cache

docker system prune

Below command will remove the following:

• all stopped containers
• all networks not used by at least one container
• all images without at least one container associated to them
• all build cache

docker system prune --all --force

Below command will remove all docker images:

docker rmi --force $(docker images --all --quiet)

Contribution

Pre-commit

Following command will help to remove trailing-whitespace, check case conflict, check added large files, check merge conflict by using isort, black and flake8 automation tools.

python3 pre-commit-2.15.0.pyz run  -a

Delete pycache files

find . | grep -E "(__pycache__|\.pyc|\.pyo$)" | xargs rm -rf
