# You can define as many [[service]]s as you'd like, here is an example with

# anything else)
#
[[service]]
## This service will be chosen when the Host header is equal to this value
## Leave this blank or remove/comment it to match any host:
# host = "api.default.svc.cluster.local"

## The default is to set the upstream Host header from its URL, if you want to
## proxy the Host header from the downstream request, uncomment this line:
# proxy_host = true

  # These are the URLs that will be balanced
  [[service.target]]
  name = "instance001"                  # Alias to show in the logs and metrics
  url  = "https://elba.mockoapp.net/s1" # URL to proxy to

  [[service.target]]
  name = "instance002"

  threshold = 3
  # Time to wait to mark a target as UP again, default: 10
  timeout   = 10
  # If all targets are down, balance between all of them instead of failing with 503
  # This can greatly increase the load in the upstream services because each request
  # received might go to all of them several times deppending on the configs above
  # default: false
  none_healthy_is_all_healthy = false

  [service.retry]
  # Attempts limit, defaults to the amount of targets times two. First attempt is also
  # counted, a limit of 6 means the first attempt and five retries.
  limit    = 6
  delay    = 100 # Millis to wait between retries, default: 100
  # Millis to wait before retrying in a target that previously failed for
  # a request, default: 3000

  # Errors that will trigger a retry, options available:
  #
  # CODE_502
  # Connection errors, like a connection refused, broken pipe, etc
  #
  # CODE_504
  # Timeout errors, like a timeout on a socket read
  #
  # CODE_404
  # CODE_429
  # CODE_500
  # CODE_503
  # ...and so on
  # Consider that response code from the upstream as a retryable error, you can pick any code
  #
  # CODE_4XX
  # Consider any code < 500 and >= 400 to be retryable
  #
  # CODE_5XX
  # Consider any code >= 500 to be retryable
  #
  # This setting defaults to ["CODE_502", "CODE_503", "CODE_504"]

# You can define more services by repeating the above section from [[service]] to the end
