Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Connecting OpenSearch to Keycloak
Before we can authenticate OpenSearch against Keycloak, we'll need to install Keycloak. The following Ansible snippet demonstrates how to deploy Keycloak onto a Kubernetes cluster using the codecentric helm chart.

sso at home?
HA Keycloak on top of Kubernetes https://github.com/codecentric/helm-charts/tree/master/charts/keycloak I dropped the chart db in favor of https://github.com/zalando/postgres-operator

Keycloak behind nginx ingress in k8s. Wrong redirect.
Yeah this error suggests that the ingress is not correctly configured to forward the given information. Maybe take a look at some keycloak helm chart e.g. https://github.com/codecentric/helm-charts/blob/master/charts/keycloak/templates/ingress.yaml

Homelab: Cluster Architecture
Having experienced the issue of identity management in past projects (I've literally published 5 web apps which became some iteration of user-profile applications), I found Keycloak to be of particular use when it comes to managing users and federating accounts. Keycloak is an open-sourced enterprise service which manages identity, authentication, authorization, and account federation which is part of the JBoss project and backed by RedHat. Since I wanted to use the Keycloak helm chart the Keycloak service runs using a Postgres backend.

Auth0 Down
Yeah, it's not the easiest thing in the world to get up and running but not quite as hard as it might seem at first look. If you are already using k8s then you can use https://github.com/codecentric/helm-charts/tree/master/chart... to deploy Keycloak fairly easily. If you're not using k8s then it is probably more of an undertaking.

Upgrading Hundreds of Kubernetes Clusters
The second one is a combination of tools: External DNS, cert-manager, and NGINX ingress. Using these as a stack, you can quickly deploy an application, making it available through a DNS with a TLS without much effort via simple annotations. When I first discovered External DNS, I was amazed at its quality.

Run WebAssembly on DigitalOcean Kubernetes with SpinKube - In 4 Easy Steps
On top of its core components, SpinKube depends on cert-manager. cert-Manager is responsible for provisioning and managing TLS certificates that are used by the admission webhook system of the Spin Operator. Let’s install cert-manager and KWasm using the commands shown here:

Easy HTTPS for your private networks
I've been pretty frustrated with how private CAs are supported. Your private root CA can be maliciously used to MITM every domain on the Internet, even though you intend to use it for only a couple domain names. Most people forget to set Name Constraints when they create these and many helper tools lack support [1][2]. Worse, browser support for Name Constraints has been slow [3] and support isn't well tracked [4]. Public CAs give you certificate transparency and you can subscribe to events to detect mis-issuance. Some hosted private CAs like AWS's offer logs [5], but DIY setups don't.
Even still, there are a lot of folks happily using private CAs, they aren't the target audience for this initial release.
