k8s info: VMware Tanzu Octant – A web-based, highly extensible platform for developers to better understand the complexity of Kubernetes clusters

Uncategorized
| Dec 3, 2019
Octant is a tool for developers to understand how applications run on a Kubernetes cluster. It aims to be part of the developer's toolkit for gaining insight and approaching complexity found in Kubernetes. Octant offers a combination of introspective tooling, cluster navigation, and object management along with a plugin system to further extend its capabilities

So how would I install this?

kubectx is a utility to manage and switch between kubectl(1) contexts. To me this is so handy I can't live without it. I am constantly using k8s everywhere from PKS (Pivotal Container Service) clusters, GKE clusters, minikube and wherever I can get my hands on a cluster.

So when I heard about kubectx and no I can't live with this and it makes my life so much easier. His how

Getting started with Pivotal Telemetry Collector

Uncategorized
| Oct 17, 2019
Pivotal Telemetry Collector is an automated tool that collects data from a series of Pivotal Cloud Foundry (PCF) APIs found within a foundation and securely sends that data to Pivotal. The tool collects:

  • Configuration data from the Ops Manager API.
  • Optional certificate data from the CredHub API.
  • Optional app, task and service instance usage data from the Usage Service API.

Pivotal uses this information to do the following:

  • Improve its products and services.

VMware Harbor Registry is an enterprise-class registry server that stores and distributes container images. Harbor allows you to store and manage images for use with Enterprise Pivotal Container Service (Enterprise PKS).

In this simple example we show what you need at a minimum to get an image on Harbor deployed onto your PKS cluster. First we need the following to be able to run this basic demo

Required Steps

Taking kpack, a Kubernetes Native Container Build Service for a test drive

Uncategorized
| Sep 10, 2019
We wanted Build Service to combine the Cloud Native Buildpacks experience with the declarative model of Kubernetes, and extend the K8s workflow in an idiomatic fashion. With this goal in mind, we leveraged custom resource definitions to extended the K8s API. This way, we could use Kubernetes technology to create a composable, declarative architecture to power build service. The Custom Resource Definitions (CRDs) are coordinated by Custom Controllers to automate container image builds and keep (more...)
