kube-monkey is an implementation of Netflix's Chaos Monkey for Kubernetes clusters. It randomly deletes Kubernetes (k8s) pods in the cluster encouraging and validating the development of failure-resilient services. kube-monkey runs at a pre-configured hour (run_hour, defaults to 8 am) on weekdays, and builds a schedule of deployments that will face a random Pod death sometime during the same day. The time-range during the day when the random pod Death might occur is configurable and defaults to 10 am to 4 pm. kube-monkey works on an opt-in model and will only schedule terminations for Kubernetes (k8s) apps that have explicitly agreed to have their pods terminated by kube-monkey. Scheduling happens once a day on Weekdays - this is when a schedule for terminations for the current day is generated.
Features
- Generate a list of eligible k8s apps (k8s apps that have opted-in and are not blacklisted, if specified, and are whitelisted, if specified)
- For each eligible k8s app, flip a biased coin (bias determined by kube-monkey/mtbf) to determine if a pod for that k8s app should be killed today
- For each victim, calculate a random time when a pod will be killed
- Docker images for kube-monkey can be found at DockerHub
- kube-monkey can be configured with a list of namespaces
- kube-monkey works on an opt-in model and will only schedule terminations for Kubernetes (k8s) apps
