Match your production environment with a local environment
Companies have migrated to Kubernetes in production but still, many developers are running the application as dev machine or using tools like Docker Compose for running and testing their application.
As most of the developers don’t need to know Kubernetes fully, we need a way for them to test their application on their local machine by running a single command.
Tools like Minikube and Draft would help us to achieve that. In this post, we will see how.
Basic Setup
To set up the development environment for the developers, the machine needs a working Kubernetes node, with other tools installed. …
Rook has gotten really popular by becoming a part of Cloud Native foundation and giving a solution for persistent storage on Kubernetes. Rook orchestrates different storage solution, but we would be setting up the ceph solution that has reached its first release.
I will be taking you through the requirements needed to setup rook on GKE, and setting them up.
Step 1. Start a Kubernetes Cluster with the ubuntu image
The Ceph requires RBD module which is not present in GKE’s default Container-Optimised OS(cos) as mentioned in the Issues 2448 & 2456. Thus, we cannot use the GKE’s default configuration…
