Cluster monitoring tools

Observability is an important part of any solution. And for cluster monitoring, I prefer to use a free solution (up to 5 hosts) - DataDog.

This repository contains its deploying manifest.

Environment

For environment values management, you can use the Consul KV. This is very simple, your variables will be automatically passed to the container with the application (containers will be restarted automatically). KV namespace is apps/monitoring/datadog/agent/environment.

For example, if you create a key apps/monitoring/datadog/agent/environment/DD_LOGS_ENABLED with a value false - the environment variable DD_LOGS_ENABLED will be available inside the container with a value false.
