Accessing Apache Kafka in Strimzi: Part 5 – Ingress

Accessing Apache Kafka in Strimzi: Part 5 – Ingress

In the fifth and final part of this series, we will look at exposing Apache Kafka in Strimzi using Kubernetes Ingress. This article will explain how to use Ingress controllers on Kubernetes, how Ingress compares with Red Hat OpenShift routes, and how it can be used with Strimzi and Kafka. Off-cluster access using Kubernetes Ingress is available only from Strimzi 0.12.0. (Links to previous articles in the series can be found at the end.)

Accessing Apache Kafka in Strimzi: Part 4 – Load balancers

In this fourth article of our series about accessing Apache Kafka clusters in Strimzi, we will look at exposing Kafka brokers using load balancers. (See links to previous articles at end.) This article will explain how to use load balancers in public cloud environments and how they can be used with Apache Kafka.

Accessing Apache Kafka in Strimzi: Part 3 – Red Hat OpenShift routes

Accessing Apache Kafka in Strimzi: Part 3 – Red Hat OpenShift routes

In the third part of this article series (see links to previous articles below), we will look at how Strimzi exposes Apache Kafka using Red Hat OpenShift routes. This article will explain how routes work and how they can be used with Apache Kafka. Routes are available only on OpenShift, but if you are a Kubernetes user, don’t be sad; a forthcoming article in this series will discuss using Kubernetes Ingress, which is similar to OpenShift routes.

Accessing Apache Kafka in Strimzi: Part 2 – Node ports

Accessing Apache Kafka in Strimzi: Part 2 – Node ports

This article series explains how Apache Kafka and its clients work and how Strimzi makes it accessible for clients running outside of Kubernetes. In the first article, we provided an introduction to the topic, and here we will look at exposing an Apache Kafka cluster managed by Strimzi using node ports.

Specifically, in this article, we’ll look at how node ports work and how they can be used with Kafka. We also will cover the different configuration options available to users and the pros and cons of using node ports.

Accessing Apache Kafka in Strimzi: Part 1 – Introduction

Accessing Apache Kafka in Strimzi: Part 1 – Introduction

Strimzi is an open source project that provides container images and operators for running Apache Kafka on Kubernetes and Red Hat OpenShift. Scalability is one of the flagship features of Apache Kafka. It is achieved by partitioning the data and distributing them across multiple brokers. Such data sharding has also a big impact on how Kafka clients connect to the brokers. This is especially visible when Kafka is running within a platform like Kubernetes but is accessed from outside of that platform.

This article series will explain how Kafka and its clients work and how Strimzi makes it accessible for clients running outside of Kubernetes.
