Amazon Linux 2 - install docker & docker-compose using 'sudo amazon-linux-extras' command
View install-docker.md

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

View Reseach Livestream.md

These are notes while researching a way to convert a browser/website to a stream. This could be used for Facebook Live or for webrecording. TL'DR:

  • I started with Phantomjs - but that didn't support the html5 video tag
  • SlimerJS supports it, but there is no way to record audio directly (though this might come from desktop audio)
  • So I moved to research ffmpeg/X11/XVFB to record it with linux which works
  • But ffmpeg has no easy way to mix streams/overlays to I moved on to OBS with overlay browser support
  • I started researching options OBS in docker and it needed best a GPU , so I move to nvidia-docker
  • And so came across building game servers on EC2/AWS using GPUs and managed to run OBS inside of GPU g2x.large machine
  • I tried streaming to twich , which works great and managed to restream 4K 60FPS youtube on an AWS instance
  • Remote control works through OBS-Remote but OBS has kinda limit in types of features

A php class to add paystack's local charge to a transaction total. Totally flops if the user pays with a foreign card.
