Here's some pointers: Update your existing Kubernetes manifests or Helm charts with the appropriate kube-monkey labels. Latency Monkey induces artificial delays that simulate service degradation . Each Lastly, Spark's built-in integration tests include a handful of fault injections like the There are an abundance of Chaos Monkey alternatives for container-based applications. The key in the cloud environment is that we need to have our services recover automatically or shift to alternative resouces so that the service can be available 247. Chaos Monkey can help us to verify whether our fallbacks are properly defined, and network latency and service breakdowns do not negatively impact our system. This version of Chaos Monkey is fully integrated with Spinnaker, the continuous delivery platform that we use at Netflix. Since Kubernetes Pod Chaos Monkey is essentially a simple shell script it can be modified quite easily. It is primarily intended for testing, continuous integration, and development environments, but it can be customized to support randomized Chaos Experiments. These watchers find your beans based on the following annotations: @Controller @RestController @Service @Repository @Component We can also define custom watchers as well. Add the following methods to app/models/post.rb, which explicitly calls the proxied TagRedis instance that is created above. All chaos policies (Monkey policies) are designed to inject behavior randomly (faults, latency or custom behavior), so a Monkey policy allows you to specify an injection rate between 0 and 1 (0-100%) thus, the higher is the injection rate the higher is the probability to inject them. Internally, we use this feature to report metrics into Atlas, our telemetry platform, and Chronos, our event tracking system. The top alternatives for Chaos Monkey testing-and-qa tool are Selenium with 46.56%, JUnit with 23.67%, Bugzilla with 11.62% market share.
