CI/CD with RedHat OpenShift
Red Hat OpenShift empowers organizations to implement flexible, scalable, and secure CI/CD pipelines that meet their evolving needs and requirements. OpenShift provides several options to implement CI/CD, here are some of the most popular options.
Jenkins on OpenShift: Jenkins is a widely used tool for Continuous Integration (CI) and Continuous Delivery (CD) and is supported by OpenShift. OpenShift provides a certified Jenkins container for building Continuous Delivery pipelines, which can scale the pipeline execution through on-demand provisioning of Jenkins slaves in containers. This allows Jenkins to run many jobs in parallel and removes the wait time for running builds in large projects.
OpenShift Pipelines: OpenShift Pipelines is a Kubernetes-native CI/CD solution based on Tekton. It provides a CI/CD experience through tight integration with Red Hat OpenShift and Red Hat developer tools. OpenShift Pipelines is designed to run each step of the CI/CD pipeline in its own container, allowing each step to scale independently to meet the demands of the pipeline.
OpenShift Builds: OpenShift Builds provides a declarative build process for creating cloud-native apps. You can define the build process in a YAML file and deploy it to create a BuildConfig object. OpenShift Builds supports extensible build strategies, such as Docker build, Source-to-image (S2I) build, and Custom build.
OpenShift GitOps: OpenShift GitOps is an Operator that uses Argo CD as the declarative GitOps engine. It enables GitOps workflows across multicluster OpenShift and Kubernetes infrastructure. Using OpenShift GitOps, administrators can consistently configure and deploy Kubernetes-based infrastructure and applications across clusters and development lifecycles.
Jenkins on OpenShift with Persistent Storage: We can deploy Jenkins on OpenShift with persistent storage to ensure that your CI/CD pipeline data is not lost in case of pod failures. This method involves creating a new project named Jenkins and deploying Jenkins with persistent storage.
CI/CD with Azure DevOps and OpenShift: We can set up a CI/CD pipeline with Azure DevOps and OpenShift by creating a service account for Azure DevOps and modifying the pipeline to support CI/CD on a commit to the master branch. This method allows you to track changes from the previous version and define pipeline variables.
Comparing the key features
These options provide a range of choices for implementing CI/CD with Red Hat OpenShift, depending on the specific needs and requirements of the organization.
