With the Kubernetes Cluster available to Harness, now we can perform the Gremlin steps to install and launch an Attack. Once you click submit, your Kubernetes cluster will be available. Open Setup -> Cloud Providers + Add Cloud Provider -> Kubernetes Cluster and select the entry to inherit the cluster details from the Delegate. Next, add a Kubernetes Cluster to Harness. When the installation is complete, the Delegate will be listed in the Harness UI. Use kubectl to install the YAML file, like this: Unpack the TAR archive file you downloaded. Install a Harness Delegate in Kubernetes in the Harness Platform at Setup -> Harness Delegates -> Download Delegates -> Kubernetes YAML.ĭownload the YAML and give it a name you will remember, perhaps using ”gremlin” as a prefix as I do in the example. In our example, we will leverage a Kubernetes Delegate. The Harness Delegates will perform work on your behalf and are needed to connect your artifacts, infrastructure, collaboration, verification, and other providers with the Harness Manager. Harness uses a worker node model called Delegates. Open another tab in your browser and navigate to the Harness Platform. If you forgot your Team Secret Key, use the Reset button to generate a new one. This is found under Company -> Team -> Configuration. In addition to the API Key, you also need to have your Team ID and Team Secret Key. You can create one by navigating to Company -> Team -> API Keys. A great way to authenticate between external systems and Gremlin is by using an API Key. Access to a Kubernetes Cluster, such as this example Amazon EKS Cluster.A Harness Account, which can be the free tier.In this tutorial, we will walk through the steps to leverage Harness, a continuous delivery platform, to install Gremlin onto a Kubernetes cluster and orchestrate Gremlin Attacks. Automating Chaos experiments with every build ensures that we prevent the drift into failure as our systems continually evolve. With Chaos Engineering, we can proactively uncover and address failure modes in our systems in order to make those systems more resilient. Continuous integration/continuous delivery (CI/CD) solutions orchestrate and automate these steps, such as triggering traditional QA testing or performing Chaos Engineering experiments to ensure reliable builds prior to pushing to production.Ĭhaos Engineering is the science of performing intentional experimentation on a system by injecting precise and measured amounts of harm in order to observe how the system responds for the purpose of improving its resilience. These steps build confidence in the quality of the code, but they are tedious to perform manually. To move software changes from development through a build process to production is a journey that requires many steps.
