            The Kubernetes project is making an effort to move away from wording that can be considered offensive, with one concrete recommendation being renaming master to control-plane. In other words control-plane and master mean essentially the same thing, and the goal is to switch the terminology to use control-plane exclusively going forward. (More info in this answer)

            The kubectl command is a command line interface that executes on a client (i.e your computer) and interacts with the cluster through the control-plane. The IP address you are seing through cluster-info is the IP address through which you reach the control-plane

            Based on the storage class spec, I think the problem is the volumeBindingMode being set as WaitForFirstConsumer which means the PV will remain unbound until there is a Pod to consume it.

            You can change it Immediate to allow the PV to be bound immediately without requiring to create a Pod.

            You can read about the different volume binding modes in detail in the docs.

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

            How to inject vault and consume hashicorp vault secrets?
            Asked 2021-Jun-14 at 23:58

            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.

            If you want to inject the vault secret into the deployment pod what you can do

            There is one great project on Github Vault-CRD in java: https://github.com/DaspawnW/vault-crd

            Vault CRD for sharing Vault Secrets with Kubernetes. It injects & sync values from Vault to Kubernetes secret. You can use these secrets as environment variables inside pod.

            the flow goes something like : vault to Kubernetes secret > and that secrets get injected into deployment using YAML same as configmap

            apart from this there is also another nice method of sidecar pattern.

            for that, there is a very nice tutorial: https://github.com/hashicorp/hands-on-with-vault-on-kubernetes

            with the hope that due to the Retain policy, the new pods (i.e. their PVCs would bind to the existing PVs (and data wouldn't get lost)

            It is explicitly written in the documentation that this is not what happens. the PVs are not available for another PVC after delete of a PVC.

            the PersistentVolume still exists and the volume is considered "released". But it is not yet available for another claim because the previous claimant's data remains on the volume.

            If you want to use kubernetes inside a docker container my suggestion is to use k3d .

            k3d is a lightweight wrapper to run k3s (Rancher Lab’s minimal Kubernetes distribution) in docker.k3d makes it very easy to create single- and multi-node k3s clusters in docker, e.g. for local development on Kubernetes.

            You can Download , install and use it directly with Docker. For more information you can follow the official documentation from https://k3d.io/ .

            To get the list of pods you dont' need to create a k8s cluster inside a docker container . what you need is a config file for any k8s cluster . β”œβ”€β”€ Dockerfile β”œ-- config └── main.py 0 directories, 3 files

            AWS Load Balancer Controller successfully creates ALB when Ingress is deployed, but unable to get DNS Name in CDK code
            Asked 2021-Jun-13 at 20:44

            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 think that the answer is to use external-dns.

            ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way.

            Setting up ingress for internal load balancing requires you to configure a proxy-only subnet on the same VPC used by your GKE cluster. This subnet will be used for the load balancers proxies. You'll also need to create a fw rule to allow traffic as well.

            Have a look at the prereqs for ingress and then look here for info on how to setup the proxy-only subnet for your VPC.
