Heroku Setup for Python and Flask
Getting virtualenv – Setuptools, pip, easyinstall on Ububtu
- Install python setuptools on Ubuntu
- Install pip on Ubuntu
- easy_install on Ubuntu
- virtualenv on Ubuntu – yes, get used to it.
sudo apt-get install python-setuptools
sudo apt-get install python-pip
- Install Python development libraries, could be optional but we will use it here.
sudo apt-get install python-dev
- Get virtual env
sudo apt-get install python-virtualenv
You might also need a public key from your Ubuntu workstation. If your workstation is secure, you can just hit enter for the passphrase.
ssh-keygen -t rsa
Install the heroku toolbelt.
- Install Heroku toolbelt on Ubuntu
- Install Heroku toolbelt on AWS running Ubuntu
wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
Now your 127.0.0.1 server is in sync with Heroku libraries.
Lets start a project.
mkdir MyHerokuPyProject
mkdir MyHerokuPyProject/source
Now, logout and login in to get heroku in the PATH, or do this;
sudo su ubuntu
Log into heroku;
heroku login
You need to make heroku aware of the public key;
heroku keys:add
Ok, let’s make sure everything is set so far by starting up virtualenv
Lets use our project directory;
cd MyHerokuPyProject
We will add a virtual environment to our Python Heroku project;
virtualenv vedir --distribute
source vedir/bin/activate
Now we can get bottle like this. Notice that I am getting the bottle library, not the bottle.py library. It’s the same thing, but if you try to fetch bottle.py it will fail. Easy_install is a pythoin installation system, so it knows that that which we seek is a .py hootinanny.
pip install Flask
Add the Python image library, which requires the development library;
pip install pil
— or —
sudo apt-get install python-setuptools sudo apt-get install python-pip sudo apt-get install python-dev sudo apt-get install python-virtualenv ssh-keygen -t rsa wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh mkdir MyHerokuPyProject mkdir MyHerokuPyProject/source
log out and log in
heroku login heroku keys:add cd MyHerokuPyProject virtualenv vedir --distribute source vedir/bin/activate pip install Flask pip install pil
Throughout this great scheme of things you will get a B- just for hard work. Exactly where you misplaced us ended up being on the specifics. As they say, the devil is in the details… And it could not be more correct at this point. Having said that, permit me tell you exactly what did deliver the results. The writing is actually rather convincing and this is most likely why I am making an effort in order to comment. I do not make it a regular habit of doing that. Second, even though I can see a leaps in logic you come up with, I am not necessarily sure of exactly how you appear to connect the points which in turn produce the actual final result. For the moment I will, no doubt yield to your issue however trust in the near future you connect your facts better.
