Resilience4j and Spring Actuator - Open circuit killing service - spring-boot-actuator

Question

I have added the following dependency to my Spring Boot project
implementation 'io.github.resilience4j:resilience4j-spring-boot2:0.14.1'
When a circuit breaker opens, I get the following response on my actuator/health endpoint, with status code 503 Service Unavailable:
{
"status": "DOWN",
"details": {
"diskSpace": {
"status": "UP",
"details": {
"total": 499963174912,
"free": 432263229440,
"threshold": 10485760
}
},
"refreshScope": {
"status": "UP"
},
"getFlightInfoCircuitBreaker": {
"status": "DOWN",
"details": {
"failureRate": "100.0%",
"failureRateThreshold": "2.0%",
"maxBufferedCalls": 1,
"bufferedCalls": 1,
"failedCalls": 1,
"notPermittedCalls": 1,
"state": "OPEN"
}
}
}
}
My AWS ECS container health check uses this endpoint to determine its health, and restarts the container on a non-200 response.
As I do not want my service to be restarted when a circuit breaker opens, is there a way to have a circuit breaker being open, without causing the status of the service to be down?
I am aware of the registerHealthIndicator: false property to get round this issue, but this removes the circuit breaker stats from actuator, which I would still like to see.

Answer 1

Since 1.2.0 you can set the allowHealthIndicatorToFail to false for this.

Answer 2

I can think of two possibilities.
1) Create a custom HealthIndicator based on resilience4j's code:
https://github.com/resilience4j/resilience4j/blob/master/resilience4j-spring-boot2/src/main/java/io/github/resilience4j/circuitbreaker/monitoring/health/CircuitBreakerHealthIndicator.java
You would need to return Health.up() or Health.unknown() to avoid the 503 from the /health endpoint.
2) Disable the resilience4j's health indicator and get the same information from the metrics actuator endpoint.
