chaoskube

0.14.0 Chaoskube periodically kills random pods in your Kubernetes cluster.

Chaoskube periodically kills random pods in your Kubernetes cluster.

Chaoskube Helm Chart

chaoskube periodically kills random pods in your Kubernetes cluster.

TL;DR;

$ helm install <helm-repo>/chaoskube

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release <helm-repo>/chaoskube

The command deploys chaoskube on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.

Uninstalling the Chart

To uninstall/delete the my-release deployment:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

By default chaoskube runs in dry-run mode so it doesn't actually kill anything.
If you're sure you want to use it run helm with:

$ helm install <helm-repo>/chaoskube --set dryRun=false

Setting label and namespaces selectors from the shell can be tricky but is possible (example with zsh):

$ helm install \
  --set labels='app=mate\,stage!=prod',namespaces='!kube-system\,!production' \
  <helm-repo>/chaoskube --debug --dry-run | grep -A7 args
    args:
    - --interval=10m
    - --labels=app=foo,stage!=prod
    - --namespaces=!kube-system,!production
    - --timezone=America/New_York
    - --excludedWeekdays="Sat,Tue"
    - --excludedTimesOfDay="12:00-18:00"
    - --excludedDaysOfYear="Apr1,Dec24"
