Dockerize a Flask Application

The Flask Application uploaded to my GitHub Here

I will dockerize the above application and show you the steps to do that

Let’s Start 🤞

  • First will add some files i don’t want to Dockerignore file
vim .dockerignore

.dockerignore

Dockerfile

.gitignore

Pipfile.lock

migrations/
  • Write the dockerfile, which is already included to the above Repo vim Dockerfile

FROM python:3

 

ENV PYBASE /pybase

ENV PYTHONUSERBASE $PYBASE

ENV PATH $PYBASE/bin:$PATH

RUN pip install pipenv

WORKDIR /tmp

COPY Pipfile .

RUN pipenv lock

RUN PIP_USER=1 PIP_IGNORE_INSTALLED=1 pipenv install -d --system --ignore-pipfile

COPY . /app/notes

 

WORKDIR /app/notes

EXPOSE 80

CMD ["flask", "run", "--port=80", "--host=0.0.0.0"]
  • Build and Test
docker build -t notesapp:0.1 .

docker run --rm -it --network notes -v /home/Osama/notes/migrations:/app/notes/migrations notesapp:0.1 bash

The above commands build and run the container, once you are inside the container configure the database

  • Configure Database
flask db init

flask db migrate

flask db upgrade
  • Run and Upgrade
docker run --rm -it --network notes -p 80:80 notesapp:0.1
  1. In a web browser, navigate to the public IP address for the server, and log in to your account.
  2. Verify that you can create a new note.

Perfect , we are done now

Enjoy the learning 👍
