Usage

Building the AMI

1. Have your shell setup with AWS credentials
2. Set the environment variable armor_agent_license. This configures the agent license key in the AMI.
3. Run make build, this will produce the AMI

Note, if you need to customize the vpc or source AMI, see variables in the makefile.

Launching an AMI instance using the test fixture

Once you've created an AMI, you can us the included test fixture to quickly deploy an instance. . It sets up a single instance which can be accessed using AWS SSM.

For all the included commands, replace the $TEST_ variables with those specific to your environment

1. Specify a VPC to use. We recommend just using the regions default VPC which can be cound using the following command. aws ec2 describe-vpcs --region=$TEST_REGION --output=json

2. Pick a subnet in the VPC found earlier, any subnet with public IPs will do aws ec2 describe-subnets --region=$TEST_REGION \ --filters "Name=vpc-id,Values=$TEST_VPC_ID" --output=json

Now, call terraform in the test/fixture folder using the following

terraform init
terraform apply\
	 -var ami_id=$TEST_AMI_ID\
	 -var vpc_id=$TEST_VPC_ID\
	 -var subnet_id=$TEST_SUBNET_ID\
	 -var region=$TEST_REGION

Then you can access the instance using

aws ssm start-session --region=$TEST_REGION --target $TEST_INSTANCE_ID

When done, use the command below to destroy the create resources

terraform destroy\
	 -var ami_id=$TEST_AMI_ID\
	 -var vpc_id=$TEST_VPC_ID\
	 -var subnet_id=$TEST_SUBNET_ID\
	 -var region=$TEST_REGION
