Compatibility

Steadybit offers a wide variety of fault injections and other building blocks for Chaos experiments. On this page, you can learn about the core concepts and find an overview of the platform's capabilities. A detailed list is available on the Steadybit Reliability Hub.

Core Concepts

In Steadybit, you will create experiments by combining various building blocks in a timeline-based editor. We call those building blocks actions.

Actions operate on targets. Steadybit comes with targets that represent various logical and physical components of your systems-under-test.

Targets and actions are exposed by extensions. Extensions are small processes running inside your infrastructure. They communicate with the Steadybit platform via an agent. As a rule of thumb, each extension exposes targets and actions related to a specific technology (e.g. containers, hosts, observability solution, etc.).

Capabilities

You can pick extensions to match the scenarios that you want to address with chaos experiments, keeping resource consumption and required permissions minimal. The following tables provide an overview of the capabilities across all extensions.

Containers

The following capabilities are available when targeting containers.
