The final product Adminator Flask Dashboard is an open-source product generated by AppSeed platform in Flask using the free Adminator UI Kit.
In a rush?
Let's see something on the screen with a few actions:
$ git clone https://github.com/app-generator/flask-dashboard-adminator.git $ cd flask-dashboard-adminator
Authenticate into Heroku platform using the terminal
$ heroku login heroku: Press any key to open up the browser to login or q to exit: Opening browser to https://cli-auth.heroku.com/auth/cli/browser/0d71eacf-151a-462d-9ba6-9c9502b9e3dc Logging in... done Logged in as email@example.com
Push the project into Heroku platform
$ heroku create Creating app... - Creating app... done, ⬢ morning-retreat-24780 https://morning-retreat-24780.herokuapp.com/ | https://git.heroku.com/morning-retreat-24780.git
The app is created using a random name
morning-retreat-24780 and should be visible on the Heroku dashboard. If you want a particular name, just execute the
create command with a third argument:
$ heroku create predator-vs-rocky
The last step - Trigger the build and Deploy the app
$ git push heroku master Counting objects: 138, done. Delta compression using up to 4 threads. ... ... boring messages ... more boring messages ... ... .. <('_')> .. <---- This is my hacky avatar and has nothing to do with anything ... remote: https://morning-retreat-24780.herokuapp.com/ deployed to Heroku remote: remote: Verifying deploy... done. To https://git.heroku.com/morning-retreat-24780.git * [new branch] master -> master
At this point, the app should be successfully deployed and we can access it from the terminal by typing
heroku open or by visiting the Heroku dashboard and click on Open App button.
That was easy right?
Heroku let you connect the app to the real Git account and trigger automatic builds when a new commit occurred.
Connect the app to the Github repo
Enable automatic deploy
To have a successful deployment, Heroku expects some files to be present in the project before we execute
git push heroku master
- runtime.txt - optional file that specify the python verison to be used
- Procfile - trigger the deployment via Gunicorn. The file contains only one line:
web: gunicorn run:app --log-file=-
The argument to the Gunicorn command,
run:app is the WSGI app, constructed by the run.py file:
# Contents of run.py from app import app, db if __name__ == "__main__": app.run()
