How can I automate environment variable checks in my application?

You can automate environment variable checks by using scripts or CI/CD tools that validate the variables before deployment.

What tools can I use for this automation?

Popular tools include Jenkins, GitHub Actions, and custom shell scripts. Each can be configured to check environment variables.

Can you provide a sample script for checking environment variables?

Sure! Here's a simple Bash script:

#!/bin/bash

required_vars=(VAR1 VAR2 VAR3)

for var in "${required_vars[@]}"; do
  if [ -z "${!var}" ]; then
    echo "Error: $var is not set."
    exit 1
  fi
done

echo "All required environment variables are set."
