Create an Infrastructure

Before you begin​

  • You can learn about the concept of chaos infrastructures & chaos environments here.

  • You will need to create an environment for your chaos infrastructure to reside within. Environments are an abstraction layer over infrastructures, and a detailed guide on the environment creation process can be found here

1. Go to the Infrastructure section​

Navigate to the /environments page (Environments on the left nav), and click on the environment you wish to install the chaos infrastructure in:

2. Enable Chaos​

Click on the Enable Chaos button:

3. Add details of the Infrastructure​

Add the details of the infrastructure such as the name, description and tags, then click on the Next button:

4. Tune the cluster level specifications​

Choose one of the following modes:

  • Cluster Wide: This mode of infrastructure installation allows targeting resources across the entire cluster, in all the namespaces, as part of an experiment.
  • Namespace Mode: This mode of infrastructure installation allows targeting resources only in the namespace where the chaos infrastructure is deployed.

By default the installation will take place in the litmus namespace and uses litmus service account, which can be configured under the K8s cluster details.

Optionally, you can also specify the node selectors and Kubernetes tolerations for chaos infrastructure deployment in the advanced section

5. Deploy your Chaos Infrastructure​

  • For cluster-wide access:
  1. Select Download, and then copy and run the kubectl command shown on your screen to install the chaos infrastructure.
  • For namespace access:
  1. Run the first kubectl command to create the target namespace.
  2. Run the second kubectl command to apply the chaos CRDs.
  3. Select Download, and then copy and run the third command to install the chaos infrastructure.

Click Done

NOTE: For HTTPS mode of installation of Chaoscenter, you will need to set SKIP_SSL_VERIFY as true in the infrastructure deployment yaml.

The newly created infrastructure will appear in the list of infrastructures:
