Fault Injection

Fault injection is a form of chaos engineering where the error rate of a service is artificially increased to see what impact there is on the system as a whole. Traditionally, this would require modifying the service’s code to add a fault injection library that would be doing the actual work. Linkerd can do this without any service code changes, only requiring a little configuration.

To inject faults into your own services, follow the tutorial.
