СI/CD Frequently Asked Questions

  1. What are CI/CD tools?
    Continuous Integration (CI) and Continuous Delivery (CD) are the must-have solutions for DevOps. With their help, developers can detect issues and bugs at early stages, fix them, implement automation, improve collaboration within the team, etc.
  2. How to find out what CI/CD tools are being used in an organization?
    CI tools are the best options whenever an organization works on project automation and requires solid reporting services. When it comes to completing build, test, and deploy tasks,CD pipeline comes into play.
  3. How to deploy application code using a CI/CD tool like Jenkins?
    Deployment is the final step of Continuous Deployment, which includes all activities to make the software/product/update/system available to be used. Once you have all the information you need, you can automate the deployments with CI/CD tools like Jenkins. Every organization has its unique needs, so Jenkins setup can also slightly differ.
