Nitrogen CLI

Nitrogen is a tool for deploying web services to AWS Nitro Enclaves. Given a dockerfile and an ssh key, Nitrogen will spin up an EC2, configure the network, and build and deploy your web service. You get back a hostname that’s ready to go. Nitrogen is fully open source and it comes with pre-built scripts for deploying popular services like Nginx, Redis, and MongoDB.

Install

Nitrogen can easily be installed with the following:

curl -fsSL https://raw.githubusercontent.com/capeprivacy/nitrogen/main/install.sh | sh

Note: An AWS account is required. If you have AWS cli configured you can retrieve your credentials with cat ~/.aws/credentials. See troubleshooting if your AWS account uses MFA

export AWS_ACCESS_KEY_ID=<YOUR ACCESS KEY>
export AWS_SECRET_ACCESS_KEY=<YOUR SECRET>

Commands

• nitrogen setup <stack_name> <ssh_public_key>
• nitrogen build <dockerfile_directory>
• nitrogen deploy <stack_name> <ssh_private_key>
• nitrogen delete <stack_name>

Features

• Spins up any enclave supported EC2 instance type (with Nitro Enclaves enabled)
• Creates a security group for a specified port.
• Sets up SSH.
• Runs a socat proxy from public internet (TCP) into the nitro enclave (VSOCK).
• Builds any Dockerfile into an Enclave Image File (EIF).
• Deploys any EIF and launches a nitro enclave.

Examples

$ nitrogen setup nitrogen-test ~/.ssh/id_rsa.pub --instance-type m5n.16xlarge
>  INFO nitrogen: Spinning up enclave instance 'nitrogen-test'.
>  INFO nitrogen::commands::setup: Successfully created enclave instance. stack_id="arn:aws:cloudformation:us-east-1:657861442343:stack/nitrogen-test/c93c7c80-5581-11ed-8a2b-0e2f3ffeccf1"
>  INFO nitrogen: User enclave information: name="nitrogen-test" instance_id="i-07daa284594ff02bc" public_ip="44.197.181.14" availability_zone="us-east-1b" public_dns="ec2-44-197-181-14.compute-1.amazonaws.com"

$ nitrogen build examples/nginx/
> Filename: nitrogen.eif

$ nitrogen deploy nitrogen-test ~/.ssh/id_rsa
> Listening: ec2-1-234-56-789.compute-1.amazonaws.com:5000

$ curl http://ec2-1-234-56-789.compute-1.amazonaws.com:5000/
> Hello World

Troubleshooting

If you have permissions issues and your aws account has MFA enabled then attempt to use a session token before running setup.

aws sts get-session-token --serial-number arn:aws:iam::<AWS ACCOUNT NUMBER>:mfa/<USER NAME> --token-code <CODE>

Export the values printed from the above command:

export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export AWS_SESSION_TOKEN=

You can also use a helper script in this library called sts.sh. Warning: this will unset any AWS environment variables related to auth that you have already set in your shell.

. sts.sh <ACCOUNT> <USER NAME> <CODE>
