Learn to use new technologies and put them all together in a project. Focusing more on CI/CD and containers.

Goals:

• Must-haves:
  • Learn/Implement microservices & distributed development systems in DevOps.
  • Create a CI system
• Should-haves: Restful APIs server & full CRUD operations client

I. Client (React):

Successfully make AJAX calls to Flask server.

• React.js (JavaScript)
• Material-UI
• Axios

II. Server (Flask):

Successfully run on local & inside Docker container. Succesffuly add volumne (mounting). Successfully add/query data to local Postgres database

• Flask (Python)
• flask_cors

III. Database (Postgres):

Successfully ran from local Postgres database & inside a Docker container.

• Local database config: server/db/config/postgreSQL.ini
• Models: Right now only takes first_name, last_name
• ORM: flask_sqlalchemy
• Serializer/Deserializer: marshmallow_sqlalchemy

Usage:

To run locally, and use local database:

• In server.py, uncomment line 12 and comment out line 13
• Create virtual environment and activate it
• Install requirements
• Run python server.py

To run in containers (web app container & postgres database container):

• In server.py, uncomment line 13 and comment out line 12
• Run docker-compose up -d at the root
• Check logs: docker-compose logs -f
• Kill containers: docker-compose down -d

Connect to Containerized Postgres:

Make sure local Postgres is stopped.

• Host name: 0.0.0.0
• Port: 5432
• Database: flask
• Username: postgres
• Password: example

To push/update image to AWS ERC:

Run aws ecr get-login --no-include-email, then copy and paste token in Terminal Run ./upload-to-ecr.sh

Continuous Improvements:

• Front-End: Create PWA, Deploy Build folder to S3, Refactor to use Hooks & TS.
• Back-End: Create Restful APIs (Right now, it's missing PUT & DELETE)
• DevOps: CI/CD
