vault-creds VS consul

Exactly, we hide this from our devs. They can add secrets to hc vault via ui or via cli and know the „keywords“ to render it to properties. Which we then provide via env vars or properties file to app. For databases we do the same, there we use https://github.com/uswitch/vault-creds which hides the database related things. For encrypted communication we used in the past a sidecar with envoy that simply took certs from vault and in our apps we added the pki ca we managed via vault. So this was also hidden and devs not had to take care of encryption in their apps (today you use a service mesh for it) ;) and especially were also not affected by expired certs, as envoy has hot reload. For Kafka we still use this mechanism to implement authn and authz. There we have a callback which rotates pods when Kafka keystone is near expiry date. The only thing our devs have to worry about is encryption as a service. There I found so far no abstraction.

The JHipster scaffolded sample application has a gateway application and two microservices. It uses Consul for service discovery and centralized configuration.

Service Discovery: Microservices need to discover and communicate with each other dynamically. Service discovery tools like etcd, Consul, or Kubernetes built-in service discovery mechanisms help locate and connect to microservices running on different nodes within the infrastructure.

After some research and testing, I landed on using Consul and Fabio as the demo infrastructure. Of course, there is a myriad of other options to accomplish this task, but because of the low configuration and ease of use, I was impressed with this pairing. Both projects are mature and well-supported, and very flexible--just because you can run them with low configuration, doesn't mean you have to. I wanted to keep this demo constrained, but the exercise did get me excited about exploring things further: circuit breakers, traffic splitting, and more complex service meshes.

The goal is to be able to use Consul SD configurations to allow for retrieving scrape targets from consul. Is this possible? Can anyone provide an example? Thank you!!

The Consul collector is production ready! Consul by HashiCorp is a powerful and complex identity-based networking solution, which is not trivial to monitor. We were lucky to have the assistance of HashiCorp itself in this endeavor, which resulted in a monitoring solution of exceptional quality. Look for common blog posts and announcements in the coming weeks!

Changed the service discovery to Consul, since this is the default in JHipster 8.

In another effort to standardize development and operations, Lob has just wrapped up our container orchestration migration from Convox to HashiCorp’s Nomad, led by Senior Platform Engineer Elijah Voigt. In this new ecosystem, one feature available to us is Consul Service Mesh (a feature of Consul, which is part of our Lob Nomad stack).
