A bit of Terraform to create a support EC2 instnace in your VPC

toolbox-ec2

A bit of Terraform to create a support AWS EC2 instance in your VPC with a public address. You can use this as a temporary jump box to perhaps run a query against your database, connect to a non-public EKS cluster, etc.

A word of warning: This thing is quite safe as you can only connect via your local ip, and of course it requires the key anyway - however, if you're building it in your company's AWS account, please ensure you have permission to create entities with public addresses on the public subnets.

Instructions

1. It's assumed you're a Terraform user already, so how you connect to AWS is your problem. I use 'awsp', choose a profile, do a aws sso login and then you run terraform apply.
2. This saves state locally. There's no need for anything else as it's not assumed you're collaborating on it with anyone else, and you just want a temporary EC2 instance to use as a jump box.
3. Edit the locals.tf file. Change 'name' to whatever you want your resources called, your_ip to your ip, the vpc and a public subnet_id to one in your existing VPC, and add anything you want installed into the user_data. You should also tweak the tags unless your name is the same as mine.

Customizations

• If you have network access to whichever AWS network you're building this in, you could just choose a private subnet.

• If you really want ssh access from anywhere, you could tell it your address is 0.0.0.0 - but, the network prefix is purposely hardcoded to /32. You'd need to change that too.

Terraform Version Support

This was built and tested with Terraform 1.0.11 - as that was the version I supported at the time and Terraform 1.2.4 - as that was the latest stable version..
