How to Check if Your Build is Deployed into a Server using a Shell Script

Why this matters

As DevOps engineers, we often automate deployments — but how do we verify that the new build actually reached the server? Instead of logging in manually every time, we can use a small shell script to automate this check.

🖥️ The Shell Script

!/bin/bash

Variables

APP_URL="http://your-server-ip:8080/health"
EXPECTED_VERSION="1.0.0"

Call the app and check version

DEPLOYED_VERSION=$(curl -s $APP_URL | grep "version" | cut -d '"' -f4)

if [ "$DEPLOYED_VERSION" == "$EXPECTED_VERSION" ]; then
echo "✅ Build $EXPECTED_VERSION is deployed successfully!"
else
echo "❌ Build not deployed. Found version: $DEPLOYED_VERSION"
fi

📌 How it works

1.Define the server endpoint (e.g., /health, /version, or your API’s status endpoint).

2.Use curl to fetch the response.

3.Extract the build/version info.

4.Compare it with the expected version.

🧪 Sample Output

If deployment succeeded:

✅ Build 1.0.0 is deployed successfully!

If deployment failed:

❌ Build not deployed. Found version: 1.2.2

🚀 Takeaway

With just a few lines of Bash, you can automatically check whether your build has been deployed correctly. This script can even be added to your CI/CD pipeline as a post-deploy verification step.
