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.
K8S - using Prometheus to monitor another prometheus instance in secure way
2 projects | reddit.com/r/codehunter | 24 Mar 2023
I've installed Prometheus operator 0.34 (which works as expected) on cluster A (main prom)Now I want to use the federation option,I mean collect metrics from other Prometheus which is located on other K8S cluster B

Deploying Jenkins on Google Cloud

In this step opta generates terraform code to deploys helm chart. You can review the plan and accept it. It will take around 2-3 minutes for the plan to get applied. For specifying values to the helm chart you can modify the values inside opta-gcp/opta.yml . Refer to jenkins helm chart for more details https://github.com/helm/charts/tree/master/stable/jenkins. After opta apply finishes you will have jenkins up and running on your infra.
k8s-secretgen: Got tired of generating secrets for testing stuff so I made a script to automate it.

I do use Helm to deploy, but the trouble with using it for secrets is that it overwrites them on an upgrade.

How to Monitor your Azure Kubernetes Cluster
2 projects | dev.to | 24 Feb 2021
To install Prometheus, the most convenient way is using the Prometheus Operator Helm Chart. Helm is a package manager for Kubernetes. It simplifies the installation by integrating most of the necessary configuration settings into one package. The following instructions are based on a blog post which describes the installation process specific for AKS clusters.
I am stuck on learning how to provision K8s in AWS. Security groups? ALB? ACM? R53?
3 projects | reddit.com/r/Terraform | 19 Mar 2023
So here’s the solution I have taken for our current stack. EKS and its dependencies are created through terraform using the eks module as well as provision a route53 subdomain and a wildcard cert. Once we have that created, I have installed this deployment into the cluster via the helm module: https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.4/. This allows me to use kuberentes resources (load balancers or ingress objects) and it will handle all the provisioning of load balancers and security groups for me, based on my application yaml and annotations. We also use https://github.com/kubernetes-sigs/external-dns to manage all of our specific host names for the applications through annotations. So to generally put, terraform manages out Kubernetes clusters, and Kubernetes manages the deployment of anything needed for the application including volumes, load balancers, hostnames though Kubernetes system deployments
Kubernetes as a Platform vs. Kubernetes as an API
6 projects | news.ycombinator.com | 17 Feb 2023
Disclaimer: I work for AWS but had nothing to do with this blog post (I'm seeing it for the first time with everyone else here).
I think this is an unfair summary of the post. Of course, using Kubernetes to orchestrate other AWS services is going to be a go-to example on the _AWS_ blog, but there is plenty of vendor-agnostic software doing similar things: DNS Records, Databases, even using Kubernetes CRDs to deploy Kubernetes.
The idea of using Kubernetes as an API to orchestrate external resources doesn't inherently lock you into any single vendor.
Does it make sense to use nginx on top of the ingress-nginx
2 projects | reddit.com/r/kubernetes | 17 Feb 2023
For the average developer an Ingress is substantially simpler to understand. For an expert such as yourself there are additional annotations which may be added, to use nginx specfic features. However the big win using the nginx ingress controller is integration with other Kubernetes features like cert manager and External DNS

I can then set annotations on the Ingress resource to tell external-dns to flip the proxy switch on the DNS record in Cloudflare:
Istio woes on eks 1.22 - external-dns version stuck to v0.7.2
3 projects | reddit.com/r/kubernetes | 2 Nov 2022
according to users in this issue they claim the external-dns image being a cause of their dns failing on kubernetes 1.22. https://github.com/kubernetes-sigs/external-dns/issues/9613 projects | reddit.com/r/kubernetes | 2 Nov 2022
I use istio and external-dns. There is no configuration in istio for it. All configuration is done in the command line options of external-dns, as shown here https://github.com/kubernetes-sigs/external-dns/blob/master/docs/tutorials/istio.md. So it's external-dns that is responsible for scanning the istio objects and creating the relevant records.
