Giving Kyma a little spin ... a SpinKube
Although I had the project on my radar, I never took a closer look at it. However, now it was the time to give it a spin ... or try. All I needed was a Kubernetes environment. As I am working in the SAP space the choice of Kubernetes is kind of predefined, namely Kyma in its managed version on the SAP Business Technology Platform.

Production GraphQL repos in Go
I could only find https://github.com/kyma-project/kyma as something close to being real-world. But my google fu is failing here. Any help would be appreciated :)

Durable Functions with Netherite on Kyma
I am using Kyma as opinionated stack on top of Kubernetes (to be precise on a Gardener cluster) for this exercise. The setup should be similar for vanilla stacks, but the API gateway must be adjusted accordingly depending on what you use.

Road trip with my friends Kyma, KEDA and Azure Functions
So you can install Kyma 1.x without own domain, but you have no access to the Kyma console UI. An issue is open for this (https://github.com/kyma-project/kyma/issues/11924) and according to the Kyma slack channel the situation will improve with the upcoming release of Kyma 2.x, but until then you must provide an own domain to get access to the Kyma console UI. From my point of view this lifts the entry barrier of trying out open-source Kyma, but currently this is the way.

Giving Kyma a little spin ... a SpinKube
Authenticating with Kyma is a (in my opinion) unnecessary challenge as it leverages the OIDC-login plugin for kubectl. You find a description of the setup here. This works fine when on a Mac but can give you some headaches on a Windows and on Linux machine especially when combined with restrictive setups in corporate environments. For Windows I can only recommend installing krew via chocolatey and then install the OIDC plugin via kubectl krew install oidc-login. At least for me that was the only way to get this working on Windows.

Windows auth with K8s on prem
It is sort of a roundabout way, but I sync Active Directory to a Keycloak realm, then use OIDC auth with kube-oidc-proxy (https://github.com/jetstack/kube-oidc-proxy) and kubelogin (https://github.com/int128/kubelogin) for OIDC-based auth to the api server.

Kubernetes in production.
Yes, I setup a cluster with no SPFs. That means an HA setup for the external load balancer. I use HAProxy for my ELB, and setup 2 instances with a VRRP + keepalived to provide HA to the ingress controller. I run the control plane private, accessible only from localhost. I setup kube-oidc-proxy (https://github.com/jetstack/kube-oidc-proxy) to expose the API server with single sign-on on the ingress controller, and use the kubelogin plugin (https://github.com/int128/kubelogin) to provide OIDC support to kubectl. I then setup Keycloak to handle OIDC/OAuth2/SAML and syncing to Active Directory, and setup groups in Active Directory to control acccess to clusters. Devs each get their own namespace in the dev cluster, with mostly cluster-admin access to their namespace. Staging/Prod clusters are locked down, with read-only access to devs. Thanks to the OIDC auth to the APIServer, when employees are onboarded & offboarded, we only need to add/remove them from groups in Active Directory and everything else just magically syncs.

Gitlab token exchange with keycloak to execute deployments with kubectl
I've successfully configured kube-apiserver to authenticate users through oidc (https://github.com/int128/kubelogin) so all the users from my keycloak realm can access to the cluster with their credentials.

RBAC MANAGEMENT
I use the kube-login plugin for kubectl (https://github.com/int128/kubelogin) along with the kube-oidc-proxy (https://github.com/jetstack/kube-oidc-proxy), using Keycloak as my OIDC provider (https://www.keycloak.org) and doing LDAP synchronization to Active Directory.

Manage user authentication in on-prem cluster
Dex oauth and kubelogin. We happen to use google auth in our org, but dex is pretty flexible. You only have to have a way to distribute server certificates. We then have documented script commands to pull certs and create kubectl fig files. OpenUnison always looked interesting, but dex has been good enough for our uses.
