A Constrained Build Environment Cannot Meet Build Requirements Tekton is a CICD engine based on a Kubernetes cluster, and it is more cloud-native than Jenkins. In plain terms, that means it is easier to develop plugins for, easier to scale, easier to observe, and more fun. Because code can only be stored on the company intranet, the build cluster can only be deployed on the office intranet.微信公众号OptimizationTektonCICDDevOpsKubernetesOperationsLearningSchedulingBuildMulti-Clusterhttps://www.chenshaowen.com/en/blog/optimizing-the-slow-of-tekton-clone-task.htmlThu, 16 Feb 2023 00:00:00 +0000Thu, 16 Feb 2023 00:00:00 +0000https://www.chenshaowen.com/en/blog/optimizing-the-slow-of-tekton-clone-task.html1. Symptom - Tekton’s Clone Task Is Slow When running the clone task, Tekton is very time-consuming; with multiple repositories it generally takes around 2 minutes 30 seconds. As shown below: A pipeline that only clones takes 2 minutes 16 seconds to run, while the clone script itself actually runs for only 1-3 seconds.微信公众号TektonKubernetesCICDDevOpsOperationsPerformance Optimizationhttps://www.chenshaowen.com/en/blog/tekton-stress-test-and-optimize-k8s-cluster.htmlThu, 10 Nov 2022 00:00:00 +0000Thu, 10 Nov 2022 00:00:00 +0000https://www.chenshaowen.com/en/blog/tekton-stress-test-and-optimize-k8s-cluster.html1.

Background 1.1 Problems with the Current Use of Jenkins The orchestration engine is unstable Jenkins is an orchestration engine written in Java, and it stops the world (STW) during a full GC. Under large-scale builds, STW can prevent Jenkins from handling new requests. Heavy builds stall Jenkins stores data in disk files; every pipeline and every build occupies a file directory, producing a huge number of files.微信公众号CICDDevOpsTektonKubernetesOperationsPipelineLearninghttps://www.chenshaowen.com/en/blog/using-kubefed-to-distribute-tekton-resource-cross-cluster.htmlSat, 26 Jun 2021 00:00:00 +0000Sat, 26 Jun 2021 00:00:00 +0000https://www.chenshaowen.com/en/blog/using-kubefed-to-distribute-tekton-resource-cross-cluster.html1. The Advantages of Multi-Cluster Tekton Builds Thanks to Kubernetes, Tekton already has good elasticity and can support large-scale builds. At the same time, developing Tasks mainly uses Yaml and Shell, which widens the range of scenarios Tekton can adapt to. The figure above is a sketch of Tekton across multiple clusters.微信公众号TektonKubeFedKubernetesMulti-ClusterCICDOperationsLearningPipelineBuildDistributed Systemshttps://www.chenshaowen.com/en/blog/how-to-implement-approval-function-in-tekton.htmlThu, 24 Jun 2021 00:00:00 +0000Thu, 24 Jun 2021 00:00:00 +0000https://www.chenshaowen.com/en/blog/how-to-implement-approval-function-in-tekton.html1. Basic Features of a CICD Platform A common CICD engine is not suitable to hand directly to the business side. The main reasons are the high learning cost for users, the lack of necessary authentication, and the difficulty of maintenance and upgrades. We usually build on top of a process engine, adapting it to the business to improve usability and encapsulating it for specific scenarios to reduce complexity.微信公众号TektonKubernetesCICDDevOpsOperationshttps://www.chenshaowen.com/en/blog/how-to-add-physical-machines-to-tekton.htmlWed, 28 Apr 2021 00:00:00 +0000Wed, 28 Apr 2021 00:00:00 +0000https://www.chenshaowen.com/en/blog/how-to-add-physical-machines-to-tekton.html1. Why Physical Build Machines Are Needed In the article How to Add a Remote macOS Physical Machine for Jenkins Pipeline Builds, I described how to add a physical build machine in Jenkins. This was not a requirement I made up on a whim — at the time, real ToB commercial customers were actually asking for a solution.微信公众号TektonCloud NativeKubernetesCICDDevOpsOperationshttps://www.chenshaowen.com/en/blog/the-concept-of-tekton-a-big-game.htmlSat, 12 Dec 2020 00:00:00 +0000Sat, 12 Dec 2020 00:00:00 +0000https://www.chenshaowen.com/en/blog/the-concept-of-tekton-a-big-game.html1. On the Aesthetics of CICD Tools In the document A Software Product Is the Output of a Team’s Capability, I mentioned that a software product is the delivery vehicle for a solution, and that its quality depends on the team’s understanding of the core problem. Only with a deep understanding of the domain can the delivered product have a chance of being good.微信公众号DevOpsTektonKubernetesCICDThoughts
