This will be a quick blog to demonstrate how to enable the (embedded) Harbor Image Registry in vSphere 7 with Kubernetes. Harbor was originally developed by VMware as a enterprise-grade private container registry. It was then donated to the CNCF in 2018 and recently became a CNCF graduated project. For this demo, we’ll activate the embedded Harbor register within the vSphere 7 Kubernetes environment, and integrate it with the Supervisor Cluster for container management and deployment. ...

This blog provides a guide to help you deploying Contour Ingress Controller onto a Tanzu Kubernetes Grid (TKG) cluster. Contour is an open source Kubernetes ingress controller that exposes HTTP/HTTPS routes for internal services so they are reachable from outside the cluster. Like many other ingress controllers, Contour can provide advanced L7 URL/URI based routing and load balancing, as well as SSL/TLS termination capabilities. Contour was originally developed by Heptio (VMware) and has been recently handed over to CNCF as an incubating project. Contour consists of a control plane that is provisioned via a K8s deployment, and an Envoy-based data plane running as a Daemonset on every cluster worker node. ...

In this post we’ll explore the vSphere 7 with Kubernetes capabilities and the detailed deployment steps in order to provision a vSphere supervisor cluster and a Tanzu Kubernetes Grid (TKG) cluster. If you are new to vSphere 7 and Tanzu Kubernetes, below are some background readings that can be used as a good start point: Project Pacific – Technical Overview vSphere 7 – Introduction to the vSphere Pod Service vSphere 7 – Introduction to Kubernetes Namespaces vSphere 7 – Introduction to Tanzu Kubernetes Grid Clusters Requirements ...

This blog provides an example for deploying a CI/CD pipeline on AWS utilising the serverless container platform Fargate and the fully managed CodePipeline service. We’ll also use Terraform to automate the process for building the entire AWS environment, as shown in the below diagram. Specifically, we’ll be creating the following AWS resources: 1x demo VPC including public/private subnets, NAT gateway and security groups etc 1x ALB for providing LB services to a target group of 2x Fargate container tasks 1x ECS cluster with a Fargate service definition (running our demo app) 1x CodePipeline definition, which builds the demo app from GitHub Repo (with a webhook trigger) and deploys it to the same Fargate service 1x ECR repository for hosting pipeline build images 2x S3 Buckets as build & artifact cache References – for this demo, I’m using these Terraform modules found on GitHub: ...

This is the third episode of our **Cloud Native DevOps on GCP **series. In the previous chapters, we have achieved the following: Built a GKE Cluster with Terraform **Created a CI/CD pipeline with GKE, GCR and Cloud Build ** This time, we will take a step further and go completely serverless by deploying the same Node app onto the Google Cloud Run platform. Cloud Run is built from an open source project named Knative, which is a serverless framework developed based on the industry proven Kubernetes architecture. Whilst Knative is developed with the same event-driven concept (like other serverless solutions), it also offers great flexibility and multi-cloud portability at a container level. ...

This is the second episode of our **Cloud Native DevOps on GCP **series. In the previous chapter, we have built a multi-AZ GKE cluster with Terraform. This time, we’ll create a cloud native CI/CD pipeline leveraging our GKE cluster and Google DevOps tools such as Cloud Build and Google Container Registry (GCR). We’ll create a Cloud Build trigger by connecting to GitHub repository to perform automatic build, test and deployment of a sample micro-service app onto the GKE cluster. ...

This is the first episode of our Cloud Native DevOps on GCP series. Here we’ll be building an Google Kubernetes Engine (GKE) cluster using Terraform. From my personal experience, GKE has been one of the most scalable and reliable managed Kubernetes solution, and it’s also 100% upstream compliant and certified by CNCF. For this demo I have provided a sample Terraform script at here. The target state will look like this: ...
