| First install pip for Python2. Download the get-pip.py file from https://bootstrap.pypa.io/get-pip.py | |
| $ cd <download location> | |
| $ sudo -H python ./get-pip.py | |
| Installing pip also installs Python3 | |
| To run Python3 | |
| $ python3 | |
| Install pip3 by just executing the same file as in the step above, but this time using Python3 | |
| $ sudo -H python3 ./get-pip.py |

This is a sample of how to send some information to logstash via the TCP input in nodejs or python. It assumes the logstash host is on 10.10.10.100 and the TCP listening input is 9563.
The logstash.conf should look something like the sample file.
The log message should be a stringified JSON object with the log message in the @message field.
To use, run the node script node sendMessageToLogstash.js, or the python script python sendMessageToLogstash.js
The below article will cover the intricacies of setting up databases and heroku in respect to a flask app. This is more like a memo and will have out of sequence instructions or solutions to errors so read thoroughly.
You'll need the packages
This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).
Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.
Switch to the master branch and make sure you are up to date:
