The Challenge of Unmanaged Devices and Apps
Organizations face significant risks in safeguarding company data when employees access information via unmanaged devices and applications. Traditional Identity and Access Management (IAM) and Mobile Device Management (MDM) solutions often fall short in addressing the security concerns associated with these unauthorized assets. To tackle this problem, OnePassword has introduced Extended Access Management, which securely controls every sign-in for all applications across any device. This offers companies a more comprehensive security solution that adapts to how users actually operate in a mixed-device environment.
Overview of Container Lab for Networking
Container Lab is a command-line interface (CLI) tool that enables users to create and manage network topologies using Docker containers. It allows users to define their networks using a simple YAML file, which then facilitates easy version control and collaboration among team members. The unique feature of Container Lab is its support for multiple vendor operating systems, allowing networking professionals to simulate various network environments. By promoting a 'labs as code' approach, Container Lab empowers users to apply familiar software development practices to their networking labs.
Advantages of Running Container Lab on Kubernetes
Integrating Container Lab with Kubernetes addresses limitations such as computation constraints on single virtual machines, enabling scaling beyond traditional configurations. With Kubernetes, users can distribute resource-heavy labs across multiple nodes, significantly enhancing the ability to run extensive network simulations. The collaboration between Container Lab and Kubernetes facilitates handling high-demand virtual operating systems without overwhelming local computing resources. This combination allows users to faithfully emulate complex network topologies that might otherwise be unfeasible on their standard hardware.
Simplifying the Transition from Container Lab to Clabernetes
Clabernetes streamlines the process of converting existing Container Lab topologies into a Kubernetes-friendly format through a tool called Clapverter. This convenient CLI tool automatically translates traditional Container Lab files into Kubernetes manifests, easing the transition for users who are already familiar with Container Lab. Clapverter tackles challenges associated with differing configuration parameters by converting necessary files into Kubernetes-native constructs like config maps. This seamless migration helps users leverage the power of Kubernetes without the need for extensive retraining.
Real-World Use Cases for Clabernetes
Clabernetes showcases its potential to handle large network environments efficiently, with real-world applications emerging in companies like OVH to validate network changes as part of CI pipelines. By enabling users to deploy expansive network architectures on cloud Kubernetes instances, organizations can better simulate production environments and test configurations without the risks associated with live systems. The tool supports the use of complex configurations, allowing users to scale their labs significantly and validate infrastructure changes accurately. As the integration of networking with cloud platforms continues to evolve, Clabernetes stands as an attractive option for network engineers looking to enhance their workflows.
On today’s episode, we cover open source Clabernetes, a tool that allows you to run Containerlab on Kubernetes. Containerlab provides a CLI for orchestrating and managing container-based networking labs. It starts the containers, builds a virtual wiring between them to create lab topologies of your choice and manages the lab’s lifecycle. We discuss the answer... Read more »
