Quick demonstration of how to utilize tkg-cli and Gitlab CICD to provision kubernetes cluster. This allows anyone to provision/scale/delete kubernetes cluster by just committing a cluster definition to git – a common usecase when employing GitOps. Overview of how it’s done: Python script gets executed as part of the GitlabCICD which does a git diff to determine the appropriate action to perform Any files

If you’re reading this – you either: sweating as you can’t recover a data from a POD that was using a PV or.. looking for ways to safely delete PODs without affecting storage stored in a PV Either way, came across the same dilemma while I was migrating my apps to argocd. Took awhile to search for this so I’m documenting for anyone wanted to have the solution. If the PV is already released, ski

Ever since I’ve started running a home-lab, one service that has been a staple for me is Pi-hole. It’s fast, reliable and low foot print DNS server that also blocks adds. More information about Pi-hole here: https://pi-hole.net/ I’ve tried different iteration of installation: from linux install to my current setup, running as a container in a stand-alone docker host. Now, I’ve started switchin

As a follow-up from my previous jenkins install, I decided to instead use gitlab to run my ci/cd pipeline due to the following reasons: Code and Jobs in one place feels more natural as execution automatically gets triggered in each code commit. No need to mess with plugins. Way easier to setup. Now, to have a real-world experience (or alteast close to it) I needed to have a good use case to apply it. Good thing my si

TKG 1.1.3 is out and with it brings an exciting change – NFS Tools is now included in the PhotonOS! This is big as it opens up ootb integration with shared storage. Previously, you need to mess with photonOS internal manually to make use of NFS for pods… and yeah -new K8S version too. Now – time for an upgrade. Before that, lets do the pre-work Upload both tkg OVA: kubernetes and haproxy and mark it

Since last week, I’ve been running harbor using a self-signed certificate. This is okay for home-lab purpose but annoying once you start integrating with Kubernetes. This is because you need to modify the each node to trust the self-signed cert to be able to push/pull images, and with TKG providing scale-out k8s installation – this is a headache to integrate. To solve this, we can use LetsEncrypt to provi

For this post, I’ll be documenting how to run Harbor behind Traefik in a kubernetes installation. Although the Harbor helm chart can be installed with nginx ingress controller – I already have an ingress controller running in my cluster and I prefer to use it instead. (Also, traefik is way easier to configure :P). Now, to install, configure the following in the values.yaml in the harbor helm chart: values

During the weekend, I wanted to try creating a CI/CD pipeline for web-applications I’ve been developing ( details on a separate post). Given the only experience I have with such technologies (CI/CD Pipeline) is seeing them from marketing slide – this is an opportunity for me to learn and document my experience. Hello Jenkins When you think CI/CD- you’ll always going to come across Jenkins. Now, whil

This post documents the experience in using ansible module for nsx-t https://github.com/vmware/ansible-for-nsxt Prerequisites The following steps were undertaken in a control VM where the ansible playbook will be executed. Install ovftool I’m using ubuntu 18.04 and have downloaded ovftool.bundle from VMware. After uploading the file, issue sh VMware-ovftool-4.3.0-7948156-lin.x86_64.bundle pip3 install --upgrade
