loki-cf-logdrain

loki-cf-logdrain.excalidraw.svg

User deployable service which implements a pipeline consisting of a small Go app and a promtail sidecar process. It presents a CF compatible logdrainer endpoint which accepts RFC5424 messages, forwards them to the promtail sidecar process, which in turn forwards the log messages to Loki , done.

Usage

Deployment should be performed using the bundled Terraform module. It injects the proper promtail config for you.

module "loki_logdrain" {
  source = "./modules/loki-cf-logdrain"
  name_postfix           = var.postfix
  cf_domain              = var.cf_domain
  cf_space_id            = var.cf_space_id
  
  loki_username = "loki"
  loki_password = "some-secret-password"
  
  loki_push_endpoint = "https://loki.some-fiesta-cluster.terrakube.com/loki/api/v1/push"
}

Binding

You can bind CF apps to the above created draining service to start delivery of logs to your Loki instance.
