Fault Injection is an inbound policy. Dataplanes whose configuration is modified are in the
FaultInjection policy helps you to test your microservices against resiliency. Kong Mesh provides 3 different types of failures that could be imitated in your environment.
These faults are Delay, Abort and ResponseBandwidth limit.
Sources & Destinations
FaultInjection is a policy, which is applied to the connection between dataplanes. As most of the policies,
FaultInjection supports the powerful mechanism of matching, which allows you to precisely match source and destination dataplanes.
FaultInjection policy is available only for L7 HTTP traffic,
kuma.io/protocol is a mandatory tag for the destination selector
and must be of value
At least one of the following Faults should be specified.
Abort defines a configuration of not delivering requests to destination service and replacing the responses from destination dataplane by
predefined status code.
httpStatus - HTTP status code which will be returned to source side
percentage - percentage of requests on which abort will be injected, has to be in [0.0 - 100.0] range
Delay defines configuration of delaying a response from a destination.
value - the duration during which the response will be delayed
percentage - percentage of requests on which delay will be injected, has to be in [0.0 - 100.0] range
ResponseBandwidth defines a configuration to limit the speed of responding to the requests.
limit - represented by value measure in gbps, mbps, kbps or bps, e.g. 10kbps
percentage - percentage of requests on which response bandwidth limit will be injected, has to be in [0.0 - 100.0] range
FaultInjection is an Inbound Connection Policy.
