Welcome to Yet Another Useless Blog
Well we hope the articles here are not totally useless :)
Who are we, you might ask. We (Thomas Jungbauer and Toni Schmidbauer) are two old IT guys, working in the business since more than 20 years. At the moment we are architects at Red Hat Austria, mainly responsible helping customers with OpenShift or Ansible architectures.
The articles in this blog shall help to easily test and understand specific issues so they can be reproduced and tested. We simply wrote down what we saw in the field and of what we thought it might be helpful, so no frustrating searches in documentations or manual testing is required.
If you have any question, please feel free to send us an e-mail or create a GitHub issue

OpenShift Pipelines - Tekton Introduction
OpenShift Pipelines is a cloud-native, continuous integration and delivery (CI/CD) solution for building pipelines using Tekton. Tekton is a flexible, Kubernetes-native, open-source CI/CD framework that enables automating deployments across multiple platforms (Kubernetes, serverless, VMs, etc) by abstracting away the underlying details.

Authentication JWT
Welcome to tutorial 10 of OpenShift 4 and Service Mesh, where we will discuss authentication with JWT. JSON Web Token (JWT) is an open standard that allows to transmit information between two parties securely as a JSON object. It is an authentication token, which is verified and signed and therefore trusted. The signing can be achieved by using a secret or a public/private key pair.
Service Mesh can be used to configure a policy which enables JWT for your services.
Mutual TLS Authentication
When more and more microservices are involved in an application, more and more traffic is sent on the network. It should be considered to secure this traffic, to prevent the possibility to inject malicious packets. Mutual TLS/mTLS authentication or two-way authentication offers a way to encrypt service traffic with certificates.
With Red Hat OpenShift Service Mesh, Mutual TLS can be used without the microservice knowing that it is happening. The TLS is managed completely by the Service Mesh Operator between two Envoy proxies using a defined mTLS policy.
