This post contains some useful AWS commands and scripts.

AWS Commands

Command
aws sts get-caller-identity

Filtering command output

  • --query PROP_PATH. Like you're using jq for querying JSON string. You can save the initial .
  • --output text|json. Output as text print values without quotes.

Most used commands

  • aws sts get-caller-identity --query Arn --output text get current user ARN

Script to verify credentials

current_credentials=$(aws sts get-caller-identity --query Arn --output text)
expected_credentials="arn:aws:iam::{ACCOUNT_ID}}:user/{USER_NAME}"

if [[ "${current_credentials}" != "${expected_credentials}" ]]; then
    echo "\033[31m INVALID CREDENTIALS \033[0m" # PRINT THIS IN RED
    return
fi

About me

I'm a Software Engineer with experience as Developer and DevOps. The technologies I have worked with are DotNet, Terraform and AWS. For the last one, I have the Developer Associate certification. I define myself as a challenge-seeker person and team player. I simply give it all to deliver high-quality solutions. On the other hand, I like to analyze and improve processes, promote productivity and document implementations (yes, I'm a developer that likes to document 🧑‍💻).
