Handle transient failures to improve application stability

We have the following applications:

• One app exposing a REST endpoint to fetch cats:
  • It is exposed at port 3000
  • It contains 1 endpoint: http://localhost:3000/cats
• One gateway that transmits the requests to the cat service

docker-compose up
# Call the url and check the logs
curl -i http://localhost/cats?maxRetry=10
# Change the query parameter to see the response when the max retry count is reached
curl -i http://localhost/cats?maxRetry=2
