There are an abundance of Chaos Monkey alternatives for container-based applications. Chaos Monkey alternatives? Chaos Monkey serves a singular purpose -- to randomly terminate instances. Azure's distributed computing architecture all but requires proper failure injection testing with tools like Gremlin, which can strain resources, disrupt network traffic, and terminate instances. Via a pseudo-randomized schedule, Namazu can attack the filesystem and IO, network packets, and Java function calls. In the example we call the delete_nodes function, passing the required label-selector argument, and setting all to true so we delete all nodes in the cluster. Name of the cloud, -s, --slot Required. Here we define a Probe element, which we've added to our steady state Probes list above, that calls the get_nodes function and retrieves the list of nodes for the specified label-selector. 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. It is important to change the default timeouts for Feign and Ribbon clients before starting a test. It can kill, pause, stop, and remove Docker containers with highly-configurable selection rules. oc adm policy add-scc-to-user privileged system:serviceaccount: # Please edit the object below.
