Setting up an environment for Veracruz on AWS Nitro Enclaves

Start a standard EC2 instance:

  • m5.xlarge or something else with at least 4 vCPUs
  • 64-bit x86
  • a security group that allows port 22 from all IPs and ports 3010 and 9090 from the VPC IPs (“My IP”)
  • an EBS volume attached (I use 64 GB for that)
  • “Nitro Enclave” enabled under “Advanced details”

The instructions that follow assume the default OS, “Amazon Linux”.

Log in to the instance and check:

  • There are at least 32 GB available (df -H .).
  • The device file /dev/nitro_enclaves exists.

Install some needed packages:

sudo yum install -y docker git openssl11 openssl11-devel

Install the AWS CLI tools (source: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-linux.html):

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

Get Docker working:

  • sudo usermod -a -G docker ec2-user
  • sudo systemctl start docker
  • Log out and log in again.
  • docker info should now give lots of info rather than an error

Install the AWS Nitro Enclaves CLI (source: https://docs.aws.amazon.com/enclaves/latest/user/nitro-enclave-cli-install.html):

sudo amazon-linux-extras install aws-nitro-enclaves-cli -y
sudo yum install aws-nitro-enclaves-cli-devel -y
sudo usermod -aG ne ec2-user

Configure Nitro Enclaves (source: https://docs.aws.amazon.com/enclaves/latest/user/enclaves-user.pdf): Edit /etc/nitro_enclaves/allocator.yaml and set cpu_count: 2, memory_mib: 512.

Start the service: sudo systemctl start nitro-enclaves-allocator.service

(If allocator.yaml is changed later it may be necessary to restart the service.)

Clone veracruz source:

git clone https://github.com/veracruz-project/veracruz.git --recursive

At this point one can save some time by using a Docker image from a registry, or one can build and run a Docker image locally as follows:

cd veracruz/docker
make nitro-run
make nitro-exec

In the Docker image, build and test Veracruz:

cd veracruz/workspaces
make nitro PROFILE=release
cd nitro-host
make test-server PROFILE=release
make test-client PROFILE=release
make veracruz-test PROFILE=release

If a test fails, adding --nocapture to the appropriate $(CARGO_TEST) command in nitro-host/Makefile may reveal a helpful error message.
