k8s | A simple Kubernetes Go client

I am trying to install jenkins on my kubernetes cluster under jenkins namespace. When I deploy my pv and pvc, the pv remains available and does not bind to my pvc.

Here is my yamls:

I couldn't find an equivalent k8s cli command to do something like this, nor any ssh keys stored as k8s secrets. It also appears to do this in a cloud-agnostic fashion.

Is it just using a k8s pod with special privileges or something?

Edit: oops, it's open-source. I'll investigate and update this question accordingly

I don't understand how to apply hashicorp vault to inject secrets in my app.

The following link shows a couple of examples https://www.vaultproject.io/docs/platform/k8s/injector/examples

I used the environment variables example from the same post. But it seems not all the env variables are injected into the app. For instance, ENVs in one of my layouts don't seem to get applied meta property="og:title" content="#{ENV['NAME']}" - shows no value. But the app is running, /vault/secrets/... has files with contents.

Here's a part of the Deployment config of my app.

When there're multiple secrets/templates, the Deployment is going to look ugly.

There's absolutely no description for configmap example but this is probably what I should be using instead of env.

I am having a problem using Kubernetes Ingress with a ASP.NET core web API.

Lets say I have a web API with three controllers (simplified code to demonstrate three routes /, /ep1, /ep2):

I am using the ECK operator, to create an Elasticsearch instance.

The instance uses a StorageClass that has Retain (instead of Delete) as its reclaim policy.

Here are my PVCs before deleting the Elasticsearch instance

I'm trying to follow instructions on this guide but under docker.

I set up a folder with:

I originally posted this question as an issue on the GitHub project for the AWS Load Balancer Controller here: https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/2069.

I'm seeing some odd behavior that I can't trace or explain when trying to get the loadBalacnerDnsName from an ALB created by the controller. I'm using v2.2.0 of the AWS Load Balancer Controller in a CDK project. The ingress that I deploy triggers the provisioning of an ALB, and that ALB can connect to my K8s workloads running in EKS.

Here's my problem: I'm trying to automate the creation of a Route53 A Record that points to the loadBalancerDnsName of the load balancer, but the loadBalancerDnsName that I get in my CDK script is not the same as the loadBalancerDnsName that shows up in the AWS console once my stack has finished deploying. The value in the console is correct and I can get a response from that URL. My CDK script outputs the value of the DnsName as a CfnOutput value, but that URL does not point to anything.

In CDK, I have tried to use KubernetesObjectValue to get the DNS name from the load balancer. This isn't working (see this related issue: https://github.com/aws/aws-cdk/issues/14933), so I'm trying to lookup the Load Balancer with CDK's .fromLookup and using a tag that I added through my ingress annotation:

I installed a Kubernetes cluster of three nodes, the control node looked ok, when I tried to join the other two nodes the status for both of is: Not Ready

On control node:

I'm trying to create an internal ingress for inter-cluster communication with gke. The service that I'm trying to expose is headless and points to a kafka-broker on the cluster.

However when I try to load up the ingress, it says it cannot find the service?
