Ory Kratos: Headless Authentication, Identity and User Management

Authentication flows are quite common in the modern day software development. What we want from one authentication has a lot of overlapping funcionality with what our other applications need. Even across different industries, you can still see the same patterns apply when it comes to Identity and User Management.

Ory Kratos solves all that user management under one umbrella of identity server, providing a clean headless API that you can ship your own UI with. It empowers you to customize the frontend, while preserving the ever-common backend that is backed by the robust SQL database.

In this blog post, we will cover the introduction and basics of Ory Kratos, as well as the steps and guides to write your integration client.

If you've always wanted to stop reinventing the wheel, reduce code duplication and to follow security best practices, then Ory Kratos and 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!
