Health Checker is an utility microservice to constantly verify if a target is ok with regards to its dependencies.
Health Checker will periodically call a /health endpoint to record its targets health.
The behavior of this endpoint is completely undefined, but requires the following structure as a response:
{
"dependencies": {
"key": {
"up": bool, # false meaning the dependency is down or unreacheable, true meaning dependecy is up and reacheable
"err": string
},
}
}
Launch it fast by running:
docker-compose up -d local
Or build this application with go build and launch it by running:
./health-checker start --log-level debug --target-health-url http://localhost:37441/health --target-name health-checker
Where <target> and <port> reflect user defines values for the target base url and port.
