reconciler | Python package to reconcile DataFrames

I'm trying to access my ETCD database from a K8s controller, but getting rpc error/EOF when trying to open ETCD client.

My setup:

• ETCD service is deployed in my K8s cluster and included in my Istio service mesh (its DNS record: my-etcd-cluster.my-etcd-namespace.svc.cluster.local)
• I have a custom K8s controller developed with use of Kubebuilder framework and deployed in the same cluster, different namespace, but configured to be a part of the same Istio service mesh
• I'm trying to connect to ETCD database from the controller, using Go client SDK library for ETCD

Here's my affected Go code:

I'm struggling with understanding how reconciliation works when dealing with nested react components. Below is my code for index.js

I am currently writing a Kubernetes Operator using Golang and the Operator SDK.

In order to know if the creation of a resource has timed out I check the CreationTimestamp property of my current resource. After a successful Update I want to update the CreationTimestamp of that resource, but when I do that, nothing happens and the CreationTimestamp stays the same...

My Reconcile loop looks something like this:

I seem to be having an issue with the way my ports are setup on this manifest, which is a simple go app. The app is configured to listen on port 3000. This container runs fine on my local machine (localhost:3000), but I get no ADDRESS when I look at the Ingress (k get ingress ...). I am getting an error logged in the AWS aws-load-balancer-controller log when I try to run this image on EKS:

I have been using kubebuilder for writing custom controller, and aware of Get(), Update(), Delete() methods that it provides. But Now I am looking for a method which mimic the behaviour of kubectl rollout restart deployment. If there is no such direct method then I am looking for correct way to mimic the same.

I am attempting to deploy a Helm chart to AKS using FluxCD. The chart has been pushed to Azure ACR using the Helm cli - "helm push ...". The chart is declared in the ACR as helm/release-services:0.1.0

I am receiving the following error after a Flux reconcile:

'chart pull error: failed to get chart version for remote reference: no chart name found'

with helm-controller logs as follows

{"level":"info","ts":"2022-02-07T12:40:18.121Z","logger":"controller.helmrelease","msg":"HelmChart 'flux-system/release-services-test-release-services' is not ready","reconciler group":"helm.toolkit.fluxcd.io","reconciler kind":"HelmRelease","name":"release-services","namespace":"release-services-test"} {"level":"info","ts":"2022-02-07T12:40:18.135Z","logger":"controller.helmrelease","msg":"reconcilation finished in 15.458307ms, next run in 5m0s","reconciler group":"helm.toolkit.fluxcd.io","reconciler kind":"HelmRelease","name":"release-services","namespace":"release-services-test"}

Below is the HelmChart resource in AKS:

I have followed the AWS official document to create an ALB controller and made sure few things like providing aws region and vpc id when creating a controller.

https://docs.aws.amazon.com/eks/latest/userguide/alb-ingress.html

However I notice the below error in the ALB contoller pod logs. I am running the controller pods and other resources in Fargate nodes with AKS running on version 1.21.0

{"level":"error","ts":1643650856.9675832,"logger":"controller-runtime.manager.controller.ingress","msg":"Reconciler error","name":"app-ingress","namespace":"backend","error":"WebIdentityErr: failed to retrieve credentials\ncaused by: RequestError: send request failed\ncaused by: Post "https://sts.us-east-1.amazonaws.com/": dial tcp: i/o timeout"}

I am watching Paul O Shannessy - Building React From Scratch

And I understand the mounting process very well but I have hard day trying to understand how React update a component and its children

The reconciler controls the update process by this method:

I am creating a new Operator with Kubebuilder to deploy a Kubernetes controller to manage a new CRD Custom Resource Definition.

This new CRD (let's say is called MyNewResource), needs to list/create/delete CronJobs.

So in the Controller Go code where the Reconcile(...) method is defined I added a new RBAC comment to allow the reconciliation to work on CronJobs (see here):
