Bring up the main website and documentation ragedb.com while you spin up an instance on docker right now:

Docker

docker pull dockerhub.ragedb.com/ragedb/ragedb
docker run -u 0 -p 127.0.0.1:7243:7243 --name ragedb -t dockerhub.ragedb.com/ragedb/ragedb:latest --cap-add=sys_nice

If you are running Docker on a Mac or Windows Host, you may see this error message:

WARNING: unable to mbind shard memory; performance may suffer:

Run Docker on a Linux host for the best performance.

Terraform

This is work in progress, if you can make this better please help!
Generate an SSH key if you don't already have one with ssh-keygen -t rsa -b 4096.
Install Terraform
Install the AWS CLI.
Configure the AWS CLI with an access key ID and secret access key.

Variables

your_region

Which AWS Region. The options are here.
E.g. eu-west-2.

your_public_key

This will be in ~/.ssh/id_rsa.pub by default.

Steps

Run terraform init.
Run terraform apply.
Wait a few minutes for the code to compile and the server to spin up.
Copy the IP output by the previous command into your browser http://x.x.x.x:/7243
Do Graphy Stuff.
Irrecoverably shut everything down with terraform destroy.

This will bring up an r5.2xlarge with 4 cores set to 1 thread per core with 100 GB of space.
