Service Mesh 1.1 released

Service Mesh OpenShift

- Thomas Jungbauer Thomas Jungbauer ( Lastmod: 2024-05-05 ) - 1 min read

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

  • Istio - 1.4.6

  • Kiali - 1.12.7

  • Jaeger - 1.17.1

Update

To update an operator like Service Mesh, the Operator Life Cycle Manager takes care and automatically updates everything (unless it was configured differently).

For the Service Mesh 1.1 update consult Upgrading Red Hat OpenShift Service Mesh
It is important to add the version number to the ServiceMeshControlPlane object. The easiest way to do so is:

  • Log into OpenShift

  • Select the Namespace istio-system

  • Goto _"Installed Operators > Red Hat OpenShift Service Mesh > ServiceMeshControlPlanes > basic-install > YAML"

  • Under spec add the following:

    spec:
  version: v1.1

Notable Changes

ServiceMeshMember Object

With the ServiceMeshMember object it is now possible that a project administrator can add a service to the service mesh, instead relying on the cluster administrator to configure the ServiceMeshMemberRoll. To do so create the following object (i.e. under the namespace tutorial)

apiVersion: maistra.io/v1
kind: ServiceMeshMember
metadata:
  name: default
  namespace: tutorial
spec:
  controlPlaneRef:
    name: basic-install (1)
    namespace: istio-system (2)
1Name of the ServiceMeshControlPlane object
2name of the service mesh namespace

  • Cert-Manager Policy Approver in OpenShift –

    One of the most commonly deployed operators in OpenShift environments is the Cert-Manager Operator. It automates the management of TLS certificates for applications running within the cluster, including their issuance and renewal. The tool supports a variety of certificate issuers by default, including ACME, Vault, and self-signed certificates. Whenever a certificate is needed, Cert-Manager will automatically create a CertificateRequest resource that contains the details of the certificate. This resource is then processed by the appropriate issuer to generate the actual TLS certificate. The approval process in this case is usually fully automated, meaning that the certificate is issued without any manual intervention. But what if you want to have more control? What if certificate issuance must follow strict organizational policies, such as requiring a specifc country code or organization name? This is where the CertificateRequestPolicy resource, a resource provided by the Approver Policy, comes into play. This article walks through configuring the Cert-Manager Approver Policy in OpenShift to enforce granular policies on certificate requests.

  • Single log out from Keycloak and OpenShift –

    The following 1-minute article is a follow-up to my previous article about how to use Keycloak as an authentication provider for OpenShift. In this article, I will show you how to configure Keycloak and OpenShift for Single Log Out (SLO). This means that when you log out from Keycloak, you will also be logged out from OpenShift automatically. This requires some additional configuration in Keycloak and OpenShift, but it is not too complicated.

  • Step by Step - Using Keycloak Authentication in OpenShift –

    I was recently asked about how to use Keycloak as an authentication provider for OpenShift. How to install Keycloak using the Operator and how to configure Keycloak and OpenShift so that users can log in to OpenShift using OpenID. I have to admit that the exact steps are not easy to find, so I decided to write a blog post about it, describing each step in detail. This time I will not use GitOps, but the OpenShift and Keycloak Web Console to show the steps, because before we put it into GitOps, we need to understand what is actually happening. This article tries to explain every step required so that a user can authenticate to OpenShift using Keycloak as an Identity Provider (IDP) and that Groups from Keycloak are imported into OpenShift. This article does not cover a production grade installation of Keycloak, but only a test installation, so you can see how it works. For production, you might want to consider a proper database (maybe external, but at least with a backup), high availability, etc.).

  • Using ApplicationSet with Matrix Generator and define individual Namespaces –

    During my day-to-day business, I am discussing the following setup with many customers: Configure App-of-Apps. Here I try to explain how I use an ApplicationSet that watches over a folder in Git and automatically adds a new Argo CD Application whenever a new folder is found. This works great, but there is a catch: The ApplicationSet uses the same Namespace default for all Applications. This is not always desired, especially when you have different teams working on different Applications. Recently I was asked by the customer if this can be fixed and if it is possible to define different Namespaces for each Application. The answer is yes, and I would like to show you how to do this.

  • Introducing AdminNetworkPolicies –

    Classic Kubernetes/OpenShift offer a feature called NetworkPolicy that allows users to control the traffic to and from their assigned Namespace. NetworkPolicies are designed to give project owners or tenants the ability to protect their own namespace. Sometimes, however, I worked with customers where the cluster administrators or a dedicated (network) team need to enforce these policies. Since the NetworkPolicy API is namespace-scoped, it is not possible to enforce policies across namespaces. The only solution was to create custom (project) admin and edit roles, and remove the ability of creating, modifying or deleting NetworkPolicy objects. Technically, this is possible and easily done. But shifts the whole network security to cluster administrators. Luckily, this is where AdminNetworkPolicy (ANP) and BaselineAdminNetworkPolicy (BANP) comes into play.
