Auto scaling a HTTP triggered application in Kubernetes using Keda
Kubernetes is getting more popular everyday and it's no wonder why! When you are running applications on-premise or in-cloud, the possibility of having the applications in a portable way is a strong one! Removing the friction for scaling-out your application when you are ready for it, or even bursting scenarios.
Creating a simple "Hello World" docker application with Express and NodeJS
For a lot of infrastructure related blog posts I would like to utilize a very basic application that spins up a web server and allows us to access it. Once we access it we simple see a welcome message but with a delay that we can configure!
Monitoring the Kubernetes Nginx Ingress Controller with Prometheus and Grafana
In a previous article I explained how we can set-up an Nginx Kubernetes Ingress Controller, but how can we now monitor this? This is what I would like to tackle in this article, on how we are able to utilize Prometheus and Grafana to start visualizing what is happening on our Ingress Controller.
Creating a Kubernetes Nginx Ingress Controller and create a rule to a sample application
Whenever you are creating an application that you want to expose to the outside world, it's always smart to control the flow towards the application behind it. That's why Kubernetes has something called
Kubernetes Ingress. But what is it?
Debugging Common Dapr Issues
As a new sort of writing, I wanted to create a "debugging" blog post where I list "my rookie" mistakes that I made while working with Dapr. I hope that by sharing I can help others to more quickly resolve their own issues 😊
Setting up Stable Baselines with Python 3.7 and WSL 2
I've been playing around a bit with Stable Baselines lately for an upcoming project. However while playing, I encountered some issues seeing that Stable Baselines currently requires Tensorflow <= 1.14 which is only supported through Python < 3.8. Due those difficulties, I thought it would be interesting to share how I set up my personal development environment from scratch to play around with Stable Baselines.
Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 2
In Part 1 I explained you how you can create a Robot Arm that can be mounted on an Xbox controller. In OpenAI Lunar Lander I then continued to see how we are able to train a lunar lander environment to land a lunar lander all by itself with a continuous action space.
Training the Continuous Lunar Lander with Reinforcement Learning, RLLib and PPO
For an upcoming blog post, I would like to have a robotic arm to land a Lunar Lander autonomously. In Part 1 I explained how we can build such a robotic arm already, but now we need to be able to go deeper into how we are able to train an environment in a simulation environment (before deploying it on a physical device).
Autonomously Landing a Lunar Lander with an Xbox Controller Robotic Arm - Part 1
Creating an Xbox Robot Arm is something that I've been wanting to do ever since I saw the post by Kevin Drouglazet who was able to utilize an Xbox Controller with an arm he created and was so friendly to publish the design files for (I am definitely not a hardware designer 😅) - thanks for that Kevin!
