Cloud Native Java Microservices with JHipster and Istio

• kdash

  13 1,948 9.0 Rust

  A simple and fast dashboard for Kubernetes

  

Note: I'm using KDash to monitor the cluster; you can try it or use kubectl, k9s, and so on as you prefer.

• okta-java-spring-k8s-istio-microservices-example

  1 8 0.0 Java

  An example microservices application using JHipster, Spring, Istio and Kubernetes

  

git clone https://github.com/oktadev/okta-java-spring-k8s-istio-microservices-example.git

• InfluxDB

  www.influxdata.com sponsored

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• k9s

  126 24,752 9.4 Go

  🐶 Kubernetes CLI To Manage Your Clusters In Style!

• jib

  46 13,360 8.0 Java

  🏗 Build container images for your Java applications.

  

We are ready to deploy now. First, we need to build and push the images to the registry. We can use the handy Jib commands provided by JHipster. Navigate to each of the microservice folders and run the commands below.

• JHipster

  63 21,214 10.0 Java

  JHipster, much like Spring initializr, is a generator to create a boilerplate backend application, but also with an integrated front end implementation in React, Vue or Angular. In their own words, it "Is a development platform to quickly generate, develop, & deploy modern web applications & microservice architectures."

  

Note: Currently, the JHipster OIDC setup does not work with Istio and there is an open issue in JHipster issue tracker for this. Alternative solutions would be to use an external authorization server with something like Open Policy Agent. We will cover this in a later blog post.

• zipkin

  36 16,713 9.4 Java

  Zipkin is a distributed tracing system

  

We can use tools like Grafana, Prometheus, Kiali and Zipkin for monitoring and observability as they work well with the telemetry provided by Istio. You can use these or use your existing monitoring stack as well.

• OPA (Open Policy Agent)

  90 9,104 9.6 Go

  Open Policy Agent (OPA) is an open source, general-purpose policy engine.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• kiali

  3 3,308 9.6 TypeScript

  Kiali project, observability for the Istio service mesh

  

We can use tools like Grafana, Prometheus, Kiali and Zipkin for monitoring and observability as they work well with the telemetry provided by Istio. You can use these or use your existing monitoring stack as well.

• envoy

  66 23,849 10.0 C++

  Cloud-native high-performance edge/middle/service proxy

  

Data plane: It's made of Envoy proxies deployed as sidecars to our application containers. Envoy is a high-performance, lightweight distributed proxy. It controls all the incoming and outgoing traffic to the container it is attached to.

• consul

  57 27,752 9.9 Go

  Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.

  

A service mesh provides features to help with common distributed microservice challenges. Like service discovery, routing, load balancing, and so on. Today we will be using Istio, one of the most popular service mesh solutions available. Istio is tailored for distributed application architectures, especially those you might run in Kubernetes. Istio plays nicely with Kubernetes, so nicely that you might think that it's part of the Kubernetes platform itself. Istio isn't the only service mesh around; we also have platforms like Linkerd and Consul, which are also quite popular.

• prometheus

  381 52,642 9.9 Go

  The Prometheus monitoring system and time series database.

  

We can use tools like Grafana, Prometheus, Kiali and Zipkin for monitoring and observability as they work well with the telemetry provided by Istio. You can use these or use your existing monitoring stack as well.

• conduit

  33 10,330 9.9 Go

  Ultralight, security-first service mesh for Kubernetes. Main repo for Linkerd 2.x.

• helm

  205 25,974 9.0 Go

  The Kubernetes Package Manager

  

You should now be able to run istioctl from the command line. Now, we can use the CLI to Install Istio to the GKE cluster. Istio provides a few Helm profiles out of the box. We will use the demo profile for demo purposes. You can choose the production or dev profile as well. The command should install Istio and set up everything required on our cluster.

• Grafana

  378 60,196 10.0 TypeScript

  The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.

  

We can use tools like Grafana, Prometheus, Kiali and Zipkin for monitoring and observability as they work well with the telemetry provided by Istio. You can use these or use your existing monitoring stack as well.
