Hello World!

By 2 Mins Read

Who am I?

My name is Thomas Rudrof and I’m a Senior Cloud Platform Engineer based in Nuremberg, Germany. I’m originally from the Fränkische Schweiz region in northern Bavaria, which is not too far from Nuremberg. You may have heard of the Fränkische Schweiz because it has the highest brewery density in the world and of course it also has the best beer!🍻 Despite living in Nuremberg I’m a big fan of FC Bayern München soccer team and soccer in general! ⚽️

Pottenstein, Fränkische Schweiz

The following YAML manifest is my way of saying “Hello World” with native Kubernetes mechanisms. It defines a Kubernetes Pod that runs a container based on the nginx image, with a volume mounted at /usr/share/nginx/html . It mounts a ConfigMap resource that contains a static “Hello World!” html file.

What does “thomasroot” mean?

Actually, thomasroot has no specific meaning. It is an artificial word made up of my first name Thomas and the word root. My surname “Rudrof” sounds similar to root. In Unix and Linux systems root refers to the superuser with the highest privileges.

What content can you find here?

I will try to create blog posts from time to time about topics that I am currently working on or am particularly interested in. The topics will primarily be related to the cloud native/Kubernetes ecosystem.

Thank you for visiting my blog. I hope you find something here that resonates with you and that you will come back to visit again in the future.

Stay tuned! 🙂
