Access Any Kubernetes Secret

You can gain access to any secret that you want in Kubernetes even if you don’t have RBAC permissions to get, list or view that secret. All you need is permission that allows you to do anything on pods and an ability to guess the names of secrets. With these two ingredients, here is how you can access any secret out there.

Religious Rituals Don't Scale With Population

There are numerous Hindu festivals celebrated throughout the year. The rituals associated with each festival differ to the extent these festivals are celebrated. I am here to recount the environmental impact of the customs Hindus are involved in. Although a ritual associated with each festival and its effect on the environment is insignificant on a small scale. But with Hindus in India being close to a billion (966 million as per the 2011 census, with the population growth rate that might be almost a billion), these rituals don’t scale very well....

Monitor your PC with Prometheus Grafana stack

How do you monitor your own computer? Of course, using Prometheus, node-exporter and Grafana. You might ask why would you wanna do that when you can simply use the operating system provided, “System Monitor”. Well, yes, you can use that. But the data you get from the OS System Monitor is coarse-grained. OS system monitor is not configurable, but this stack is. It is like running htop but where you can go back in history, unlike htop, which only shows the current state....

Kubernetes The Hard Way in "Vagrant"?

If you are studying for the Certified Kubernetes Administrator (CKA) exam, you might have come across folks recommending Kelsey Hightower’s Kubernetes the Hard Way. It is an excellent first step for someone who has no idea about the components that form a Kubernetes cluster.

Kubernetes Bangalore Meetup

How we manage Kubernetes Bangalore Meetup?

I took the reins of the Kubernetes Bangalore Meetup back in 2017. I have been organising the meetup since then. Earlier with Suraj Narwade, Aditya Konarde and now with Prakash Mishra. Over time the meetup has grown a lot, now it boasts about 5000 members. Organising meetup earlier was a straightforward affair, especially with Narwade and Konarde being my colleagues and friends. We could chat about the upcoming meetup at any time we would like, and it was all spontaneous....

On Compounder Skills

There are specific skills which you should acquire early on in your life. These skills are the foundational skills. Everything you do after developing these skills becomes better, faster and easier. I call these skills Compounder Skills. Derived from the term “Compound Interest”. The idea is that once you are laced with a particular compounder skill, you can apply it in various fields of your life. An example of a compounder skill that most humans get exposed to is “school education”....

Importance of Typing Skills

Yes, today’s topic is typing skills. I think not many people stress about it, but it is a very underrated skill, yet useful in our daily lives. I typed the most organic way anybody starts doing it. Look at the keyboard when you are typing and fix mistakes after looking at the monitor. I moved my hand around on the keyboard and only used index fingers to touch the keys as if other fingers were glued together away from the keyboard....
