DevOps Hunter Security Automation

Hello DevOps, Platform Engineers, SREs, and Kubernetes Administrators! Modern applications are increasingly built using microservices and deployed on Kubernetes clusters. While Kubernetes provides scalability, resiliency, and automation, troubleshooting failures can sometimes become challenging because issues may originate from multiple layers of the platform. One of the biggest mistakes engineers make during troubleshooting is focusing on a single component without understanding the overall architecture. Effective Kubernetes troubleshooting requires a structured approach that helps quickly identify where the problem exists. Over time, while working on Kubernetes administration, troubleshooting production incidents, and practicing Kubernetes scenarios from KodeKloud labs by Munshi Mohammad, I found it useful to classify Kubernetes issues into three major categories: Application Failures Control Plane (Master Node) Failures Worker Node Failures By identifying the category first, trouble...

Hello Guys! in this post we are going to explore about the Kubeconfig. This is a special configuration that will be part of Kubernetes Security. We can configure multiple clusters and different users can access these Kubernetes cluster. We can also configure the users can have access to multiple clusters. When we started working on Kubernetes Cluster there is a config file automatically generated for us.  To access a Kube Cluster using the certificate files generated for admin user can be given as follows: kubectl get pods \ --server controlplane:6443 --clisent-key: admin.key --client-certificate admin.crt --certificate-authority ca.crt Every time passing all these TLS details(server,client-key,client-certificate, certificate-authority) including in the kubectl command is tedious process. Instead of this we can move TLS Certificate file set into a config file that is called kubeconfig file. The usage will be as follows kubectl get pods --kubeconfig config Usually this...
