How to Access AWS From Azure VM Using OpenID Connect

In the day to day operations of a software application, it is common to be in a position to manage and handle multiple cloud providers at the same time.

This can be due to the business requirements or because of technological constraints on the primary cloud provider of the company.

In this blog post we will see how to grant an Azure Virtual Machine access to AWS services, without storing any long-lived credentials and with the power of OpenID Connect.

If you've worked with either cloud, or want inspiration on how to apply this technique to your setup, then this blog post is for you.

GitOps Continuous Deployment: FluxCD Advanced CRDs

FluxCD is a powerful ecosystem of GitOps operators that can be enabled on-demand as per the requirement of your environment. It enables you to opt-in for the features you need and to disable the ones you don't.

As the complexity and requirement of your environment grows, so does the need for extra tooling to cover the implementation of the features you need.

FluxCD comes with more than just the support for Kustomization and HelmRelease. With FluxCD, you can also manage your Docker images as new versions get built. You can also get notified of the events that happen on your behalf by the FluxCD operators.

Stick till the end to see how you can take your Kubernetes cluster to the next level using advanced FluxCD CRDs.

cert-manager: All-in-One Kubernetes TLS Certificate Manager

Kubernetes is a great orchestration tool for managing your applications and all its dependencies. However, it comes with an extensible architecture and with an unopinionated approach to many of the day-to-day operational tasks.

One of these tasks is the management of TLS certificates. This includes issuing as well as renewing certificates from a trusted Certificate Authority. This CA may be a public internet-facing application or an internal service that needs encrypted communication between parties.

In this post, we will introduce the industry de-facto tool of choice for managing certificates in Kubernetes: cert-manager. We will walk you through the installation of the operator, configuring the issuer(s), and receiving a TLS certificate as a Kubernetes Secret for the Ingress or Gateway of your application.

Finally, we will create the Gateway CRD and expose an application securely over HTTPS to the internet.

If that gets you excited, hop on and let's get started!
