Using Ingress and SSL termination in Kubernetes

It is ok for test or development environment to use Service component for exposing our application to external requests. However, we need Ingress for the same logic. It is the actual entry point to external requests in the K8S cluster. Ingress controller plugins are manually installed on the cluster. We are going to use Nginx Ingress. If your setup had an external load balancer/proxy server, it would sit in front of the Ingress controller but we will ignore it this time. This is to avoid exposing K8S components to outside completely. We are using Minikube in this example.

50+ Useful Kubernetes Tools for 2020 - Part 2

Introduction

Last year, we provided a list of Kubernetes tools that proved so popular we have decided to curate another list of some useful additions for working with the platform—among which are many tools that we personally use here at Caylent. Check out the original tools list here in case you missed it.

According to a recent survey done by Stackrox, the dominance Kubernetes enjoys in the market continues to be reinforced, with 86% of respondents using it for container orchestration.

And as you can see below, more and more companies are jumping into containerization for their apps. If you’re among them, here are some tools to aid you going forward as Kubernetes continues its rapid growth.

Kubernetes in the Cloud: Strategies for Effective Multi Cloud Implementations

Kubernetes is a highly popular container orchestration platform. Multi cloud is a strategy that leverages cloud resources from multiple vendors. Multi cloud strategies have become popular because they help prevent vendor lock-in and enable you to leverage a wide variety of cloud resources. However, multi cloud ecosystems are notoriously difficult to configure and maintain.

This article explains how you can leverage Kubernetes to reduce multi cloud complexities and improve stability, scalability, and velocity.

Kubernetes: Your Multi Cloud Strategy

Maintaining standardized application deployments becomes more challenging as your number of applications and the technologies they are based on increase. As environments, operating systems, and dependencies differ, management and operations require more effort and extensive documentation.

In the past, teams tried to get around these difficulties by creating isolated projects in the data center. Each project, including its configurations and requirements were managed independently. This required accurately predicting performance and the number of users before deployment and taking down applications to update operating systems or applications. There were many chances for error.

Kubernetes can provide an alternative to the old method, enabling teams to deploy applications independent of the environment in containers. This eliminates the need to create resource partitions and enables teams to operate infrastructure as a unified whole.

In particular, Kubernetes makes it easier to deploy a multi cloud strategy since it enables you to abstract away service differences. With Kubernetes deployments you can work from a consistent platform and optimize services and applications according to your business needs.

The Compelling Attributes of Multi Cloud Kubernetes

Multi cloud Kubernetes can provide multiple benefits beyond a single cloud deployment. Below are some of the most notable advantages.

Stability

In addition to the built-in scalability, fault tolerance, and auto-healing features of Kubernetes, multi cloud deployments can provide service redundancy. For example, you can mirror applications or split microservices across vendors. This reduces the risk of a vendor-related outage and enables you to create failovers.

Supporting the Evolving Ingress Specification in Kubernetes 1.18

What is Kubernetes Ingress

When deploying your applications in Kubernetes, one of the first challenges many people encounter is how to get traffic into their cluster. Kubernetes ingress is a collection of routing rules that govern how external users access services running in a Kubernetes cluster. There are three general approaches for exposing your application:

  • Using a NodePort to expose your application on a port across each of your nodes
  • Using a LoadBalancer service to create an external load balancer that points to a Kubernetes service in your cluster
  • Using a Kubernetes Ingress resource

What’s new in Kubernetes 1.18 Ingress

There are three significant additions to the Ingress API in Kubernetes 1.18:

  • A new pathType field
  • A new IngressClass resource
  • Support for wildcards in hostnames

The new pathType field allows you to specify how Ingress paths should match. The field supports three types: ImplementationSpecific (default), exact, and prefix. Explicitly defining the expected behavior of path matching will allow every ingress-controller to support a user’s needs and will increase portability between ingress-controller implementation solutions.

The IngressClass resource specifies how Ingresses should be implemented by controllers. This was added to formalize the commonly used but never standardized kubernetes.io/ingress.class annotation and allow for implementation-specific extensions and configuration.

You can read more about these changes, as well as the support for wildcards in hostnames in more detail in a previous blog post.

Edge Security Policy at Kubernetes Ingress Using Helm and Envoy

Introduction: EnRoute Helm Chart

Helm is a popular package manager choice for Kubernetes. Installation of software, managing versions, upgrading versions, and finding charts from the registry are key benefits of Helm.

EnRoute helm chart installs the EnRoute Ingress Controller and provides easy configuration options to define policy for a service. The helm chart provides fine-grained control to define L7 policies with its ability to enable/disable plugins for a service using configuration options that can be specified when the helm is invoked.

For example, to enable the JWT plugin, simply invoke:

This enables the JWT plugin for the service httpbin

EnRoute also supports plugins/filters to extend functionality and enforce policies. The features page lists the available plugins for the Gateway. More details about each of the plugins can also be found on plugin pages.

Kubernetes Ingress - All you need to know!

What is Kubernetes Ingress?

Kubernetes Ingress is a k8 API object that orchestrates and decides the exposure of all the external access to services defined within the cluster. That is, it routes the traffic and controls the same through the resource.

Ingress manages the external exposure and access to the services basically HTTP and HTTPS routes. It is termed useful mostly when we want to have some external HTTP(s) connections to expose it to the services or applications within the pods inside the cluster. For the same, we configure the ingress resource to the services through external DNS-wise URLs, load-balancers, etc.
