This is a very short and hopefully simple introduction on how to use Git when you would like to contribute to projects hosted on github.com. The same workflow should also work for projects on gitlab.com.

To test a second application, a bookinfo application shall be deployed as an example.

The following section finds it’s origin at:

Using Ansible Resource Manager with an ARM template and a simple Ansible playbook to deploy a Virtual Machine with Disk, virtual network, public IP and so on.

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.

Cheat sheet for various Red Hat Satellite tasks from a newbie to a newbie.

April 10th 2020 Red Hat released Service Mesh version 1.1 which supports the following versions:

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.

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.
