Fight Your Instincts — Your Default Behaviour is Hurting You

Fri, 29 Oct 2021 11:05:07 +0530

We behave in a certain way. It is shaped by various factors like our upbringing, environment, privilege, etc. But most of the time, it is shaped by our instincts. Until pointed out, we continue to act with our instincts. This instinct-driven behavior is our default behavior.

I am making a case that anyone who has never rebelled against or resisted their default behavior will find it hard to achieve success in this world. All the successful people we see have done something that required fighting the default behavior, which led them to achieve something exceptional and become successful.

How to create a Systemd daemon quickly?

Sat, 19 Jun 2021 16:16:00 +0530

If you have a script or a binary and want to run it as a Systemd service, keep following. This blog will show you how to take any such executable code and run it using Systemd. Sure, you can do similar stuff using Docker as well. Although there are certain downsides of using Docker (alone) for managing the daemons. Systemd is good at log management on the node over a Docker container. If a container fails, you may or may not have access to the logs. Systemd provides constructs in managing dependencies quite well. And finally, you may not be using Docker on the machine, while Systemd is quite ubiquitous on any Linux.

How to import 'any' Kubernetes package into your project?

Sun, 30 May 2021 09:40:00 +0530

The client libraries that Kubernetes ships are meant to be imported, and you definitely don’t need this post explaining how to import them in your Golang based project. A simple go get ... should do the trick. But, what about the packages that are not meant to be imported? Or the ones that cannot be imported because of “technical reasons” ? Could you simply add them to your import statements in the .go file, and the go binary will do the right thing when you build the code? Well, let’s find that out!

Testing 'fedora' and 'CentOS' kompose package

Tue, 14 Mar 2017 00:31:57 +0530

I generally do kompose package testing for fedora and CentOS. So here are the steps I follow.

Fedora

For respective fedora version use the tag respectively for e.g. 25 for fedora 25.

Starting the environment:

docker run -it registry.fedoraproject.org/fedora:26 bash

Running tests:

# Inside the container
# Pull packages from the testing repository
dnf --enablerepo updates-testing -y install kompose

# Check the kompose version
kompose version

# Install the testing dependencies
dnf install -y jq make

# Pull the git repository to run the functional tests
git clone https://github.com/kubernetes/kompose/
cd kompose
git reset --hard $(kompose version | cut -d "(" -f2 | cut -d ")" -f1)

# Run cmd tests
make test-cmd

CentOS `epel` repo

Spin the CentOS environment in container.

This is the new home for my blog. I use to write on wordpress before. You can find the older blog at https://deshmukhsuraj.wordpress.com. But I wanted to have my own domain and wordpress was charging exorbitantly to connect a custom domain to wordpress, so I just ditched it and started writing here. This is much more convenient.
