This repository contains the code and instructions for an assessment used during the interviewing process for operations roles at Vouch.
This system consists of an EC2 node which writes a document to AWS DynamoDB containing some information about the instance created by AWS. Terraform is used to provision the infrastructure.
Your assignment consists of the following tasks:
- Setup an AWS Account.
- Deploy the infrastructure with Terraform. All the resources defined in this repository can run in the AWS Free Tier.
- Find the bug in the terraform code, create a git patch and send it to the recruiter you're in contact with. Do not create a pull request.
- Terraform 0.14
- git
- ssh
The EC2 instance boots the latest Amazon Linux 2 and runs a shell script through cloud-init user data.
In this shell script, the instance will retrieve instance metadata and store it in an AWS DynamoDB table.
The terraform code requires setting a variable named public_key. This should be the public key of the key pair for launching the instance.
You can provide any public key for which you have access to the corresponding private key.
If everything properly executes you should be able to see an item like the following in a Dynamo Table named vouch-operations-MachineState
.
However, there is a bug in the code that prevents the expected result to be completed. We would like you to find the bug, solve it and create a git patch file for the proposed code changes.
In the interest of keeping the assessment a fair challenge for each candidate, do not share your work or solution. This is the reason why we ask you to provide a git patch instead of creating a pull request.
Some guidelines:
- Do not fork the repository, only clone it.
- Work on your local git clone to create the patch. Do not push your work to a public repository.
