Q&A
Kubernetes for Developers
Kubernetes has emerged as a game-changing technology in the world of containerized application deployment and management.
As more organizations embrace microservices architectures and cloud-native development, understanding Kubernetes has become essential for developers looking to stay at the forefront of modern software practices.
When combined with the leading containerization system, Docker, Kubernetes offers developers a streamlined way to deploy, scale, and manage their applications, whether running locally or in the cloud.

However, navigating Kubernetes' intricacies can be daunting, especially for those new to container orchestration.
To help you get a handle on pods, nodes, clusters, Kubelets and all the rest, Dan Wahlin, a Principal Cloud Developer Advocate at Microsoft, will present a session titled Kubernetes for Developers at Live! 360, the big multi-conference developer/IT pro education event coming to Orlando next month.
"If you've heard about Docker and Kubernetes but haven't made time to learn more about them, then this is the session for you!" said Wahlin, who creates training courses, speaks at conferences and meetups around the world, and offers webinars on a variety of technical topics. For this, he promises that attendees will learn:
- The key players in Kubernetes
- The role of containers and how they fit into Kubernetes pods
- How to deploy workloads to Kubernetes
We caught up with Dan to learn more about his Nov. 20, 75-minute, intermediate-level session.
VisualStudioMagazine: What inspired you to present a session on this topic?
Wahlin: I'm passionate about helping developers understand Kubernetes and how it can be used to solve real-world challenges.
"Kubernetes has a lot of 'moving parts' so can be intimidating at first, but in the session, I'll break everything down into simple terms and show visual diagrams to help people understand and get started using Kubernetes."

Kubernetes has a lot of "moving parts" so can be intimidating at first, but in the session, I'll break everything down into simple terms and show visual diagrams to help people understand and get started using Kubernetes. I enjoy getting people from "I know very little about Kubernetes" to that "aha" moment where they understand it and the benefits it can provide.
What are some of the most common challenges developers face when working with Kubernetes, and how will this session address them?
Developers often struggle with the complexity of Kubernetes and integrating it into their workflows. This session will simplify these challenges by demonstrating how to use the Kubernetes features available in Docker Desktop effectively to deploy pods, work with services, and more.
What do you think sets Kubernetes apart from other container orchestration platforms?
Kubernetes stands out due to its extensive community support, flexibility when it comes to working with containers, documentation, cloud vendor support, and its status as the leading container orchestration platform.
Will the session cover any specific tools or extensions that enhance Kubernetes' functionality for developers?
The session will focus on using tools like Docker Desktop but will also mention alternatives such as minikube and Rancher Desktop, all of which enhance the functionality and accessibility of Kubernetes for developers. Although running Kubernetes in the cloud is certainly an option (and will likely be used by developers in various scenarios), understanding how it can be run directly on their machines helps people experiment more and learn about the overall features it offers.
What advice would you give to development teams looking to transition from traditional deployment methods to using Kubernetes?
Kubernetes isn't required for every workload so it's important to determine if an application would benefit from moving to Kubernetes or if doing so would only add unnecessary complexity. If it's determined that Kubernetes would be a viable option, start small by containerizing a few services and gradually integrate Kubernetes into your deployment workflow and pipeline, leveraging tools like Docker Desktop for a smooth transition. Get a good understanding of the different parts of Kubernetes before diving in and ensure that you work with your Kubernetes administrator to ensure that proper monitoring and logging is in place and that reports/dashboards are accessible so you can more easily resolve issues that arise.
How important is the open-source community to the development and growth of Kubernetes, and how can developers get involved?
The open-source community is crucial to Kubernetes' evolution and overall growth, offering continuous innovation and support. Developers can get involved by contributing to the project, participating in community forums, and sharing their experiences. Getting involved in the Kubernetes OSS community isn't required to understand and use Kubernetes, but it's a great way to learn how Kubernetes works under the covers.
What are some key resources or communities where developers can find support and best practices for using Kubernetes?
Developers can find support and best practices through resources like the official Kubernetes documentation, community forums, GitHub repositories, and online learning platforms that offer courses on Kubernetes.
Note: Those wishing to attend the conference can save hundreds of dollars by registering early, according to the event's pricing page. "Save $300 when you register by the Early Bird deadline of Oct. 25!" said the organizer of the event, which is presented by the parent company of Visual Studio Magazine.
