CI CD Pipeline: A Gentle Introduction

Continuous delivery is an extension of continuous integration in which your team automatically deploys new code to a repository . It can then be deployed to production at any time based on your needs and the needs of your clients. The added automation used by continuous delivery greatly reduces the amount of effort required to deploy code. With continuous delivery, you can respond more quickly to anything from changes in the market to security flaws. Most organizations will not be comfortable with development teams controlling deployments to production environments.

Having a CI/CD pipeline in place brings many benefits not only to the product team but also to the organization’s business values. Therefore, having access to all versions of the system is crucial to QA as well as other stakeholders. Moreover, keeping the latest version updated will help improve the quality and reliability of QA feedback of bug logged. The steady upward trend of CI/CD terms over the past 5 years is prominent in the software product industry.

Pipelines are decomposed into their individual steps, and dependencies are specified. The CI/CD system examines the dependencies and assembles the steps on demand. This can produce great efficiencies in larger projects that have many interrelated components. The CI/CD system, rather than blindly building a dependency, can cache the dependency so that it is only built once, regardless of the number of dependent components. Everything else is secondary, and many functions development, IT, and operations teams perform are tedious and can actually lead to burnout.

By leveraging the custom resource definitions in Kubernetes, Tekton uses the Kubernetes control plane to run pipeline tasks. By using standard industry specifications, Tekton will work well with existing CI/CD tools such as Jenkins, Jenkins X, Skaffold, Knative, and OpenShift. CI/CD is the backbone of a DevOps methodology, bringing developers and IT operations teams together to deploy software.

What is the CI/CD pipeline?

In this phase, we run automated tests to validate our code’s correctness and the behavior of our product. The test stage acts as a safety net that prevents easily reproducible bugs from reaching the end-users. It’s essentially a runnable specification of the steps that any developer needs to perform to deliver a new version of a software product. In the absence of an automated pipeline, engineers would still need to perform these steps manually, and hence far less productively.

If you’re just getting started on a new project with no users yet, it might be easy for you to deploy every commit to production. You could even start by automating your deployments and releasing your alpha version to production with no customers. Then you can ramp up your testing culture and make sure that you increase code coverage as you build your application.

Implementing a CI/CD Practice for ML Pipelines

You have to define success metrics before you start the transition to CD automation. This will help you to consistently analyze your software, developing progress help refining where needed. Peer code review each pull request to solve a problem in a collaborative manner. Take the guided tour and learn from many tutorials and example projects in Semaphore documentation.

Depending on the size of the software it could take hours, days or weeks, requires detailed checklists and many manual steps, and special expertise. Deployments often failed and required developer workarounds or urgent assistance. Testing – once the pipeline builds the code, it passes it through a series of tests to verify its readiness for deployment. These should ideally be automated tests, although manual tests are common before deployment. A pipeline may sound like overhead, but once it’s set up and running, it is an enabler for higher productivity, better developer experience, shorter development cycles, and more satisfied users.

While this does lower the cognitive burden on infrastructure developers, it doesn’t eliminate it, as they must be an expert in the behavior of the declarative systems they operate. This is typified by Kubernetes manifests, Terraform templates, and of course Cloudify blueprints. The next step beyond having frequently tested code, is to automate the delivery and deployment processes so users can get their hands on fixes and updates as quickly as possible.
