In this repository, I started to learn how to deploy Flask apps using Docker containers (which I need for "Pulse" (open education tracking & performance app) and "Research Cloud" (research cloud for co-authors on EC2).

• displaying "Hello world"
• using environment variables (e.g., for non-sensitive information)
• reading in secret credentials from a .txt file

• export FLASK_APP=app
• flask run

1. Install prerequisites (Docker, AWS, Lightsail) from here

2. Build docker image: docker-compose build

3. Run docker image: docker-compose up

tbd

• View running docker images: docker ps

• Remove docker images: docker rm <IMAGE_NAME-SEE-DOCKER-PS>

• Start/stop docker images: docker start <IMAGE>, docker stop <IMAGE>
