Customizable Professional Developer Portfolio for Beginners with Docker Stack
This repository was created as a resource for my YouTube tutorial.
- Run your app and view it in your browser @
localhostorlocalhost:80:
cd dev_portfolio_simplified
docker compose up
- update
init_db.pywith your personal information and projects. - update
static/style.csswith your favourite styling. - update
static/script.jswith your JavaScript browser intercations. - saving each of the above files, and refreshing the web page - will automatically update your website locally.
- switch to a production server like Green Unicorn, by updating your Dockerfile:
FROM python:3.12-slim
WORKDIR /app
RUN pip install flask
RUN pip install gunicorn
COPY . .
CMD ["gunicorn", "--workers=5", "--bind", "0.0.0.0:5000", "main:app"]
- pre-build a Docker image, to later specify it in your docker-compose file:
docker build -t my-portfolio .
- update docker-compose file with the pre-build image:
services:
web:
image: my-portfolio:latest
ports:
- "80:5000"
volumes:
- ./:/app
deploy:
restart_policy:
condition: any
updater:
image: my-portfolio:latest
command: ["tail", "-f", "/dev/null"]
volumes:
- ./:/app
deploy:
restart_policy:
condition: any
- activate swarm more and deploy the GUI and database services in a stack:
docker build -t my-portfolio .
docker swarm init
docker stack deploy -c docker-compose.yml my-portfolio
- update
init_db.pyand save it. - find container id of the database updater service with:
docker ps - update database service without collapsing the application
docker exec [CONTAINER ID GOES HERE] python3 /app/init_db.py
