Use docker compose locally to run azure functions

Config Makefile, adding the following lines:

deploy:
        sls package
        docker compose up --build
    
install-docker:
        @echo "=========================================Installing dependencies Time Tracker========================================="
        pip install --upgrade pip
        pip install -r requirements.txt
        @echo "Completed! "

For environment variables you should contact some team partner and ask for variables of the .env file.

After, you need to check docker-compose.yml and validate you file looks like:

version: '3.9'
services:
  api:
    build: 
      context: .
      dockerfile: ./Dockerfile
    ports:
      - 8080:80
    env_file:
      - .env
  database:
    image: postgres:14
    ports:
      - "5433:5432"
    environment:
      - POSTGRES_USER=${DB_USER}
      - POSTGRES_PASSWORD=${DB_PASS}
      - POSTGRES_DB=${DB_NAME}

To run azure functions on docker compose, you need to add the following lines to Dockerfile:

FROM mcr.microsoft.com/azure-functions/python:3.0-python3.6

ENV AzureWebJobsScriptRoot=/home/site/wwwroot \
    AzureFunctionsJobHost__Logging__Console__IsEnabled=true

RUN apt install unzip && apt-get install make

COPY .serverless/azure-time-tracker.zip /home/site/wwwroot/

RUN cd /home/site/wwwroot/ && unzip azure-time-tracker.zip && rm azure-time-tracker.zip 
RUN cd /home/site/wwwroot/ && make install-docker

When you have been terminated the config, you can run the command make deploy to build the docker container with azure-functions and database.

If you have some changes in the project to deploy you need to execute, make deploy to update the files on the container.

For test the app, go to your browser and type:

http://localhost:8080/api/activities
