This is a working Haskell application with one route (/), which returns an
empty JSON object and a 200 status.
The Nix configuration is set up to allow AWS EC2 provisioning and deployment.
You must change the following to your own credentials:
let
region = "eu-central-1";
accessKeyId = "your-access-key-id-here";
You may change the AWS region if you wish.
You must have a file named ~/.ec2-keys in your home directory, with contents
like the following:
AKIAJ700000000000000 tBoCp111n111UE3o33333333333SiglhhhhhhQGs your-access-key-id-here
With Nix and NixOps installed, you can create a new deployment:
nixops create -d minimal services.nix aws.nix
And then you can deploy it:
nixops deploy -d minimal
Don't forget to modify the AWS security group so it allows HTTP access!
Once the application is deployed, you can access it by its IP address.
Any time you change the code and wish to redeploy, you must first modify the NixOps deployment with the following command:
nixops modify -d minimal services.nix aws.nix
I would like to see rate limiting with nginx, and a strategy for banning scrapers and brute-force attempts, possibly with fail2ban.
n.b. The Haskell application must be compiled on a Linux machine.
