Role based access control - RBAC - KubernetesMilan Das
?
This document discusses Role Based Access Control (RBAC) in Kubernetes. It begins with an introduction of the speaker and then provides an overview of RBAC including roles, bindings, and how authentication works. It demonstrates how to configure RBAC and manage users through extensions like Auth0 to restrict access at the namespace and cluster level. The speaker then shows a demo of setting up RBAC roles and bindings in a Minikube cluster to configure secure access to the Kubernetes dashboard.
User authentication and authorizarion in KubernetesNeependra Khare
?
This document discusses user authentication and authorization in Kubernetes. It describes how Kubernetes uses external services like Active Directory and LDAP for user authentication. It also explains the different types of users in Kubernetes including normal users, service accounts, and how kubeconfig files are used. The main authorization mechanism in Kubernetes is Role-Based Access Control (RBAC) which uses roles and role bindings to control access to Kubernetes API resources and operations.
The document discusses the Berkeley Packet Filter (BPF) and its application in Linux for efficient packet filtering at the kernel level. It details the architecture, operations, and instruction sets of BPF, including debugging and implementation in user-space applications, as well as advanced features like Just-In-Time (JIT) compilation. Additionally, it covers extensions of BPF and its use in kernel security mechanisms, such as seccomp, which applies filters to system calls.

It concludes with discussing DevOps practices after adopting Kubernetes and potential next steps to learn more advanced Kubernetes topics.
The document outlines the content from the 2018 ifunfactory dev day, featuring various programming languages such as C++, C#, and Python, and discussing topics like performance profiling using tools like gprof and Valgrind. It also covers Linux performance enhancements using eBPF and BCC, as well as details about HTTP APIs and database interaction. Additionally, the document includes references to specific technologies and tools used during the event, along with performance metrics and benchmarks.
Rohit Sharma will present on Ansible playbooks. The presentation will cover an overview of Ansible, its features, architecture, and a comparison to Puppet and Chef. It will include a demonstration of Ansible. Attendees are asked to be punctual, provide constructive feedback, keep devices on silent mode, and avoid disturbances during the session.
The document discusses container storage interfaces, the lifecycle of images in software development, and security concerns related to Docker containers. It emphasizes the importance of version control and consistent environments throughout development stages, as well as the use of registries like Harbor for image synchronization. Additionally, it highlights security measures such as content trust, vulnerability scanning, and access controls for different user roles.
