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.
- 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 loginand then you runterraform apply. - 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.
- 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.
-
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.
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..
