What is IronWorker?

IronWorker is a robust, serverless compute service that lets developers run a massive number of concurrent tasks and workloads in the cloud without managing servers. At its core, it allows for background job processing making it a perfect candidate for CI/CD systems.

Why do we need CICD in Today’s DevOps World?

CI/CD, pivotal to DevOps best practices, has transformed the software development lifecycle:

  • Continuous Integration: The practice of automating the integration of code changes from multiple contributors into a single software project. It is one of the primary DevOps best practices, allowing developers to frequently merge code changes into a central repository where builds and tests then run. Automated tools are used to assert the new code’s correctness before integration
  • Continuous Deployment: Facilitates automated code deployment to staging/production, eliminating manual hurdles.

These mechanisms ensure software updates, whether new features or patches, reach end-users swiftly and securely.

How Can IronWorker be Used for CI/CD?

  1. Parallel Execution of Tests: One of the most time-consuming parts of the CI process is running unit and integration tests. With IronWorker's capability to run tasks concurrently, you can break down your test suite and run them in parallel, leading to faster feedback cycles.
  2. On-Demand Environment Setup: Each IronWorker task can start with a fresh environment, ensuring that every test or build process runs in an isolated, consistent space. This removes the “it works on my machine” problem.
  3. Scalability: Whether you have 10 tests or 1,000 tests, IronWorker scales on demand, ensuring that your CI/CD pipeline doesn't become a bottleneck.
  4. Integration with Popular VCS Platforms: You can trigger IronWorker tasks using webhooks from popular version control platforms like GitHub, Bitbucket, or GitLab. Every time a developer pushes code or creates a pull request, the CI/CD process can automatically kick off in IronWorker.
  5. Notifications and Feedback: Post-execution hooks can be used to notify other platforms or tools about the success or failure of tasks. This can be integrated into communication tools like Slack, alerting the team of build results.
  6. Deployment Automation: Once the code passes all tests and checks, IronWorker can also handle the deployment phase. By integrating with platforms like AWS, Google Cloud, or Azure, IronWorker can ensure that code gets deployed to the right servers or services.
  7. Cost Efficiency: Since you are billed for the actual usage, you don’t have to worry about overprovisioning or underutilizing dedicated CI/CD servers with IronWorker.

Setting Up IronWorker as a CI/CD System

  1. Create an account here and install the IronCLI.
  2. Configure your Environment: Set up your code environment, including any dependencies, within a Docker container. This container will be executed by IronWorker. For example, let’s build a docker image that just checkouts the code from github repo. Here is a Dockerfile:
    FROM ubuntu:latest
    RUN apt-get -y update
    RUN apt-get -y install git

    Build and publish to Dockerhub:

    docker build -t YOUR_DOCKER_IMAGE .
    docker push YOUR_DOCKER_IMAGE

    Of course, in production you may need to add build (if you’re using golang for example), test, deploy, etc. commands.

  3. Specify Iron credentials using env variables and register your docker image with Iron:
    iron register YOUR_DOCKER_IMAGE

    The above command also registers a new worker. Webhook URL is automatically generated for each worker. Sending POST request to this url triggers a new task to run.

  4. Set Up Triggers: Add IronWorker Webhook URL to your your VCS platform settings to trigger the CI/CD process in IronWorker upon code pushes or pull requests. Find the IronWorker Webhook URL on Iron dashboard (“CODES” tab):IronWorker Webhook URLAdd the above Webhook URL to webhook settings on VCS side. For example, if you’re using Github, you should navigate to the “Settings” tab of the repo and choose “Webhooks” on the left menu:Adding Webhook URL to Github
  5. Handle Notifications: Set up post-task hooks to notify your team about build and deployment results.
  6. Monitor and Optimize: provides detailed logs and metrics. Monitor these to ensure that your CICD process is optimized for performance and cost.

Example Use Case: Deploying a Web Application

Scenario: A SaaS company develops a web application with frequent feature releases. The development team is distributed, leading to multiple daily code pushes.

Challenge: With regular feature deployments, the team requires a CI/CD system that efficiently handles multiple parallel builds, offers swift feedback, and ensures consistent environment setups.

Solution with IronWorker:

  • The team prepares a Docker image with necessary tools and dependencies (for example: git, AWS CLI) needed for building, testing and deploying their app.
  • IronWorker is configured to initiate a CICD process whenever there's a code push to their GitHub repository.
  • Tests are executed concurrently, considerably reducing wait times.
  • On successful test completion, the code is automatically deployed to the cloud (AWS for example).
  • Team members receive immediate notifications on Slack regarding the build and deployment status.


Having a robust CI/CD system is non-negotiable. IronWorker emerges as a front-runner, offering scalability, flexibility, and efficiency, all while being cost-effective. As teams seek tools that can match their growing demands and adapt to evolving needs, IronWorker stands out as a prime choice for those looking to optimize their CI processes.
