The Consul Education team has created a couple new guides to help you secure and monitor Consul service registrations.
Deploy Services in Consul Connect's Service Mesh
Consul Connect secures service-to-service communication. Connect allows you to secure communication between services with proxies. In this new guide, you'll deploy two demo applications into a zero-trust network. The guide provides step-by-step instructions on how to register services and their proxies.
Ensure Services Registered with Consul are Healthy
One of the primary roles of the Consul agent is to manage system-level and application-level health checks. In this guide, you'll deploy two services with different health checks and a health check for the agent. Finally, you'll test that Consul DNS only returns healthy services.
