This application illustrates the various type of failure that can happen in a distributed system

Dev

You can run this application in dev mode using:

> mvn quarkus:dev

Fault Injection

Fault are injected using:

> curl "localhost:8080/fault?mode=$MODE&ratio=$RATIO"

$MODE can be:

• NONE
• INBOUND_REQUEST_LOSS
• SERVICE_FAILURE
• OUTBOUND_RESPONSE_LOSS

$RATIO is a float in [0, 1). The default ratio is 0.5.

If neither the mode and the ratio are set, it resets it to NONE / 0.5

Here are a few examples:

> curl "localhost:8080/fault?mode=INBOUND_REQUEST_LOSS"
> curl "localhost:8080/fault?mode=SERVICE_FAILURE&ratio=0.7"
> curl "localhost:8080/fault?mode=OUTBOUND_RESPONSE_LOSS&ratio=0.1"
> curl "localhost:8080/fault" # Reset
