Deploying Tanzu Kubernetes Grid to AWS fails with ‘InstanceProvisionFailed’

VMware, Kubernetes, , , ,
The issue

When deploying Tanzu Kubernetes Grid to AWS, the deployment was failing with the following output:

unable to set up management cluster, : unable to wait for cluster and get the cluster kubeconfig: error waiting for cluster to be provisioned (this may take a few minutes): cluster creation failed, reason:'InstanceProvisionFailed @ Machine/tkg-aws-mgmt-control-plane-dqb4v', message:'1 of 2 completed'
The Cause

When we reviewed the CAPA logs (Cluster API AWS provider) we found the following errors logged: Continue reading Deploying Tanzu Kubernetes Grid to AWS fails with ‘InstanceProvisionFailed’ →

vRA AKS Tanzu Mission Control Header

Using vRA to deploy Azure AKS Clusters and register with Tanzu Mission Control

VMware, , , , ,

This walk-through will detail the technical configurations for using vRA Code Stream to deploy AWS EKS Clusters, register them as Kubernetes endpoints in vRA Cloud Assembly and Code Stream, and finally register the newly created cluster in Tanzu Mission Control.

This post mirrors my original blog post on using vRA to deploy AWS EKS clusters.

Requirement

Tanzu Mission Control has some fantastic capabilities, including the ability to deploy Tanzu Kubernetes Clusters to various platforms (vSphere, AWS, Azure). However today there is no support to provision native Azure AKS clusters, it can however manage most Kubernetes distributions.

Therefore, when I was asked about where VMware could provide such capabilities, my mind turned to the ability to deploy the clusters using vRA Code Stream and provide additional functions on making these AKS clusters usable.

High Level Steps
  • Create a Code Stream Pipeline
    • Create an Azure AKS Cluster
    • Create AKS cluster as endpoint in both Code Stream and Cloud Assembly
    • Register AKS cluster in Tanzu Mission Control
    • Export the SSH keys for the AKS cluster to the docker host.
Pre-Requisites

Create the variables to be used

First, we will create several variables in Code Stream, you could change the pipeline tasks to use inputs instead if you wanted. Continue reading Using vRA to deploy Azure AKS Clusters and register with Tanzu Mission Control →

vRA Code Stream – Preserving files and artifacts created in a CI Task

General, VMware, ,

Whilst creating a pipeline and using CI Tasks to run some CLI tools, I needed to save the outputted files from the container used for the CI Task so I could use them once the pipeline is completed.

Code Stream has a feature for CI Tasks called “Preserve Artifacts” to enable this, where by files in your working directory are saved to the “/sharedPath” folder location of the Docker Host where your container runs.

Below I’m going to show you how to use this feature.

  • First on your pipeline configure a Working Directory

    • The pipeline can be changed easily for use with vRA on-prem
  • AWS Account that can provision EKS clusters
  • A Docker host to be used by Code Stream
  • Tanzu Mission Control account that can register new clusters
  • VMware Cloud Console Tokens for vRA Cloud and Tanzu Mission Control API access
  • The configuration files for the pipeline can be found in this GitHub repository

Postman Header

Postman – Logging in results in losing my offline work

General, , ,
The Issue

When working with Postman in an offline mode or not signed in, then choosing to sign in, you lose access to your Collections and Environments you have worked on previously.

The Cause

In later versions, Postman introduce the Scratchpad. This is an offline area where your data is saved to.

When you create a new account in the app, you should be presented an option to move your data from your scratchpad.

If you already have an account to log into, you do not seem to get this option.

The Fix
  • Within Postman application > Click the Settings Cog > Select “Scratch Pad”

Postman - Scratch Pad

So now you should be able to see your offline data. If you can, you need to manually export your data then change back to your workspace and import the data.

Postman - export collection

If you are still unable to find your data. I recommend you follow this article from the Postman support site on “how to recover my data”. I did not personally have much success with this method.
