satisfactory dedicated server on aws

Satisfactory dedicated server on AWS ECS

A CloudFormation stack that you can run in your AWS account to host up a dedicated Satisfactory server.

Thanks to for the Docker image!

Runs on AWS ECS

The dedicated server application runs on ECS Fargate, so you get a more-or-less "serverless" setup. It uses Fargate Spot, which allows you to get the cheapest possible setup, though AWS may choose to stop and restart your server. FWIW I've never actually observed that happening.

You're going to start up a Linux EC2, set up its firewall rules, and connect to it.

  • If you're not doing production work always try and use the sandbox account, so log into sandbox account.

  • The first thing you need is an AMI, which is like a snapshot that is the starting point for your machine. Go to to find ubuntu AMIs. These are like from-scratch instances that are kept up-to-date with security patches. If you search for 14.04 that'll be the latest stable ubuntu release, then you're looking for one that's in the right region (generally that's us-east-1), the right architecture (usually amd64) and the right instance type (usually that's instance-store). Copy the

  • Clicking on one of the ami-12345 links will pop you over to the AWS EC2 console and start you down the road of creating the instance.

  • First you'll have to choose an instance type. You'll want the smallest (i.e. cheapest) one th

little code review
function onEachFeature(feature, layer) {
/* From the perspective of reading this function, it would be easier if you think about it in a linear fashion
What does this function do?
1) get a single feature
2) parse some specific properties out of the feature
3) use those properties to generate a string of HTML
4) build a popup from that HTML
Right now its a little hard to read because you're jumping around between those steps a bit
