Getting the GitHub Verified commit badge when using Visual Code on Mac OS X

General, , , , ,
The Issue

Recently I’ve started to use Visual Code as my editor on Mac OS X, and using it with my GitHub Repos. It’s pretty cool! However I noticed that when I submit a commit via code, I do not see the verified badge.

github commit view - verified

The Cause

When I look at my global git config on my Mac OS X machine, I can see that I’ve configured the settings so that my user details are passed to GitHub as an author of the repository.

git config --global --list

git config --global --list

The Fix

We need to setup a GPG public key to be used by git on our machine when interacting with GitHub. Continue reading Getting the GitHub Verified commit badge when using Visual Code on Mac OS X →

VMware CMTY Podcast Appearance – Discussing Tanzu Mission Control and vROPs

General

Thanks to this blog post, I was delighted to be invited as a guest on the VMware CMTY Podcast (YouTube Page) hosted by Eric Nielsen and Matt Langguth. 

Originally I was going to discuss the out of the box vROPs dashboards such as finding out how long a VM has been powered off for, however Eric threw a curve ball at me 5 minutes before the podcast asking if I would discuss my more recent blog posts on Tanzu Mission Control, Tanzu Kubernetes Grid and then wrap up with vROPs.

It was a fun session!

Find this on your favourite podcast platform under “VMware CMTY Podcast” such as the below:

The Cause

Older releases of Ubuntu are moved to an archive server, so you need to update your repo lists.

The Fix
# backup your sources file
cp /etc/apt/sources.list /etc/apt/sources.list.bak 

# replace the links with the archive address
sudo sed -i -re 's/([a-z]{2}.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list

# run update again
sudo apt-get update && sudo apt-get dist-upgrade

Understanding the VMware Tanzu Kubernetes Terminology

VMware, , , , , , , ,

It’s not uncommon for me to see the question asking for an explanation of VMware Tanzu Kubernetes terminology and differences between similar named products. As per the below tweet. This is my blog post to address the Tanzu Kubernetes terminology and use.

Twitter thread asking about TKGm and TKGs

First, we’ll break down the high level names and products. Then move into Tanzu Kubernetes products.

What is VMware Tanzu?

VMware Tanzu is a brand name covering VMware’s modern applications suite of products, just like vRealize is the suite name for VMware’s cloud management products.

Tanzu Mission Control – Upgrading Kubernetes for a provisioned cluster

VMware, Kubernetes, , ,

Now we understand how to deploy a Tanzu Kubernetes Cluster using Tanzu Mission Control, let’s look at the next lifecycle step, how to upgrade the Kubernetes version of the cluster.

Below are the other blog posts in the series.

Tanzu Mission Control 
- Getting Started Tanzu Mission Control 
- Cluster Inspections 
- Workspaces and Policies  
- Data Protection 
- Deploying TKG clusters to AWS 
- Upgrading a provisioned cluster 
- Delete a provisioned cluster 
- TKG Management support and provisioning new clusters
- TMC REST API - Postman Collection
- Using custom policies to ensure Kasten protects a deployed application

When a cluster which has been provisioned by TMC, and therefore managed by TMC, has an available upgrade, you will see an “i” icon next to the version on the clusters UI view, hovering over this will tell you there is an upgrade ready.

TMC - Clusters - Upgrade Available

Click the cluster name to take you into the cluster object to see the full details,

  1. click the actions button
  2. and select upgrade.

TMC - Cluster - Actions - Upgrade

The Upgrade Cluster dialogue will appear. Select the version you want to upgrade to and click upgrade.

TMC - Cluster - Upgrade Cluster - Select Version

On both the Cluster list and Cluster Detailed view, the status will change to upgrading.

TMC - Cluster Upgrading 2TMC - Cluster Upgrading

Once the upgrade has completed, the cluster will change back to ready and show the updated version.

TMC - Cluster upgrade complete

Wrap-up and Resources

In this quick blog post, we used Tanzu Mission Control to upgrade a provisioned Tanzu Kubernetes Grid cluster which was running in AWS. All the steps provided in this blog post can be replicated using the TMC CLI as well.

As a reminder, to take real advantage of TMC I recommend you read the follow posts:

Tanzu Mission Control 
- Getting Started Tanzu Mission Control 
- Cluster Inspections 
- Workspaces and Policies  
- Data Protection 
- Deploying TKG clusters to AWS 
- Upgrading a provisioned cluster 
- Delete a provisioned cluster 
- TKG Management support and provisioning new clusters
- TMC REST API - Postman Collection
- Using custom policies to ensure Kasten protects a deployed application

You can get hands on experience of Tanzu Mission Control yourself over on the VMware Hands-on-Lab website, which is always free!
