IBM UrbanCode Deploy (UCD) is a powerful automation tool that makes deploying applications faster, easier, and more reliable. Instead of manually pushing code and dealing with configuration headaches, UCD handles deployments in a repeatable and consistent way. It helps teams streamline their release process, minimize errors, and deploy confidently across multiple environments.
Prerequisites
Before jumping in, you’ll need a Red Hat Linux server, an IBM UrbanCode Deploy installation (or access to an existing UCD server), and a sample application to deploy. If you’re comfortable using basic Linux commands, you’re good to go!
Step 1: Installing the IBM UrbanCode Deploy Agent
To get started, the first thing you need is the UCD agent running on your server. This agent is responsible for handling deployments from the UCD server, so without it, nothing happens. First, download the agent installer from your UCD server. You can do this with wget, replacing <UCD_SERVER> with the actual address of your server:
wget https://<UCD_SERVER>/tools/ibm-ucd-agent.zip
Once the download is complete, extract the package into a directory where the agent will live. A good place to keep it is under /opt/ucd-agent:
unzip ibm-ucd-agent.zip -d /opt/ucd-agent
Next, navigate to the agent’s bin directory and install it:
cd /opt/ucd-agent/bin
./install-agent
Before starting the agent, you need to make sure it knows where to find your UCD server. Open the agent.properties file in /opt/ucd-agent/conf/ and set the server URL. Once that’s done, start the agent with:
/opt/ucd-agent/bin/agent start
Now, hop over to the UCD web interface and check under Resources → Agents to make sure your agent is online. If it’s listed there, you’re all set!
Step 2: Creating a Deployment Process
With the agent running, it’s time to set up a deployment process in UCD. A deployment process is essentially a series of steps that define how your application is deployed, including things like copying files, restarting services, and running configuration scripts.
Head over to the UCD web interface and navigate to Processes. Here, create a new process and give it a meaningful name. In the process designer, start adding the steps your deployment needs. For example, if you’re deploying a web application, you might want to copy files from an artifact repository to your web server. You can do this using a shell script step:
cp -r /opt/artifacts/myapp /var/www/html/myapp
If your application requires a service restart, add a step to restart it after deployment:
systemctl restart httpd
Once you’ve defined all the necessary steps, save your deployment process so it can be used later.
Step 3: Setting Up an Application in UCD
Now that we have a deployment process, we need an application to tie everything together. In UCD, applications are collections of components that get deployed together.
Go to the Applications section and create a new application. Inside the application settings, define the components that make up your app. For example, if your app has both a web frontend and a backend service, each should be defined as a separate component.
Next, link your application to the deployment process you created earlier. This tells UCD what steps to follow when deploying your app. Then, set up different environments like Test, Staging, and Production so that you can deploy to each one separately when needed.
Step 4: Running a Deployment
Now for the fun part—actually deploying your application! Navigate to your application’s Environments tab, select the environment you want to deploy to, and hit Deploy. Choose the deployment process you created earlier, and let UCD take care of the rest.
As the deployment runs, you can watch the progress in the UCD web interface. If everything goes smoothly, your application should be up and running on the target server. To verify, try accessing your application in a web browser or running:
curl http://localhost/myapp
If you see the expected response, congratulations! Your deployment was successful.
Step 5: Automating and Scaling Your Deployments
Once you have a working deployment, you’ll want to automate it to make things even smoother. UCD allows you to trigger deployments automatically based on code commits or new builds. You can configure these triggers in your CI/CD pipeline so that new versions of your app are deployed automatically without manual intervention.
UCD also supports blueprints, which help you manage infrastructure as code and automate provisioning in cloud environments. If you’re deploying across multiple servers, using blueprints can make your life much easier.
To keep things running smoothly, take advantage of UCD’s monitoring and reporting features. The Deployment History and Dashboard views provide insights into past deployments, success rates, and potential issues. Keeping an eye on these metrics will help you fine-tune your deployment strategy over time.
Troubleshooting Tips
Even with automation, things can go wrong. Here are a few common issues and how to fix them:
-
The UCD agent isn’t connecting to the server? Check if the agent service is running with:
/opt/ucd-agent/bin/agent statusIf it’s not running, restart it and double-check the
agent.propertiesconfiguration. -
The deployment fails? Look at the deployment logs in the UCD web interface to see where it’s getting stuck. Common issues include missing files, incorrect permissions, or service restarts failing.
-
Application changes aren’t taking effect? Make sure the old version isn’t being cached. Try clearing temporary files or restarting the web server.
Conclusion
That’s it! You’ve successfully set up IBM UrbanCode Deploy on Red Hat Linux and deployed an application. With UCD, you can automate deployments, reduce errors, and scale your application delivery efficiently. Keep exploring its features like rollback strategies, environment-specific configurations, and integrations with other DevOps tools to take your deployments to the next level. Happy deploying!
