Simulate AWS Faults

AWSChaos can help you simulate fault scenarios on the specified AWS instance. Currently, AWSChaos supports the following fault types:

  • EC2 Stop: stops the specified EC2 instance.
  • Detach Volume: uninstalls the storage volume from the specified EC2 instance.

To easily connect to the AWS cluster, you can create a Kubernetes Secret file to store the authentication information in advance.

A Secret file sample is as follows:

  • name means the Kubernetes Secret object.
  • namespace means the namespace of the Kubernetes Secret object.
  • aws_access_key_id stores the ID of the access key to the AWS cluster.
  • aws_secret_access_key stores the secrete access key to the AWS cluster.
note

Before you create an experiment using Chaos Dashboard, make sure the following requirements are met:

  1. Chaos Dashboard is installed.

  2. Chaos Dashboard can be accessed via kubectl port-forward:

    1.  kubectl port-forward -n chaos-testing svc/chaos-dashboard 2333:2333

    Then you can access the dashboard via http://localhost:2333 in your browser.

  4. In the Choose a Target area, choose AWS FAULT and select a specific behavior, such as STOP EC2.

  5. Submit the experiment information.

  1. Write the experiment configuration to the awschaos-ec2-stop.yaml file, as shown below:

    Based on this configuration example, Chaos Mesh will inject the ec2-stop fault into the specified EC2 instance so that the EC2 instance will be unavailable in 5 minutes.

    For more information about stopping EC2 instances, refer to .

  1. Write the experiment configuration to the awchaos-ec2-restot.yaml file:

    Based on this configuration example, Chaos Mesh will inject ec2-restart fault into the specified EC2 instance so that the EC2 instance will be restarted.

    For more information about restarting the EC2 instance, refer to the AWS documentation - Reboot your instance.

  2. After the configuration file is prepared, use kubectl to create an experiment:

    1. kubectl apply -f awschaos-ec2-restart.yaml

  1. Write the experiment configuration to the awschaos-detach-volume.yaml file:

    Based on this configuration example, Chaos Mesh will inject a detail-volume fault into the specified EC2 instance so that the EC2 instance is detached from the specified storage volume within 5 minutes.

    For more information about detaching Amazon EBS volumes, refer to the .

    1. kubectl apply -f awschaos-detach-volume.yaml

The following table shows the fields in the YAML configuration file.
