etcd VS consul

When building Kubernetes and configuring the Etcd service, if there is a misconfiguration or vulnerability risk point mentioned in the previous chapter, an attacker can use the Etcd risk point to launch an attack. We list the common attack methods of attackers here, and guide readers to understand the risks and threats faced by the Etcd service by means of attack and defense. Before we start to introduce common attacks, let's first understand a common etcd command line tool - etcdctl. etcdctl is a command line client that provides some concise commands. Users can interact with etcd services directly using the commands provided by etcdctl without using the HTTP API. It can be downloaded from the following address: https://github.com/coreos/etcd/releases Next, we analyze several attack scenarios one by one. the exposure way of public network

Can etcd be used as reliable database replacement? Since it is distributed and stores key/value pairs in a persistent way, it would be a great alternative nosql database. In addition, it has a great API. Can someone explain why this is not a thing?

rqlite gives you the functionality of a rock solid, fault-tolerant, replicated relational database, but with very easy installation, deployment, and operation. With it you've got a lightweight and reliable distributed relational data store. Think etcd or Consul, but with relational data modelling also available.

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).
