Create on demand bastions with Fargate

AWS Bastion

This work is largely based on jdhollis/bastions-on-demand. I'm not a big fan of Terraform or Clojure so I rewrote it using Cloudformation and ruby.

Setup

1. Create a S3 bucket for storing lambda code. Create this however you want.
2. Update the variables in deploy-stack.sh
   • BUCKET: the name of the bucket created in the previous step
   • CLUSTER_VPC_ID: the VPC that the basion should belong to
   • CLUSTER_DEFAULT_SG_ID: the default SG ID for the VPC
   • CLUSTER_SUBNET_IDS: a comma separated list of subnets IDS
3. Run ./deploy-stack.sh to create/update the Cloudformation stack
4. Build and push the bastion image to ECR
   • cd image
   • ./login.sh
   • ./build.sh
   • ./push.sh
