Slim and Secure Container Images with Slim.ai

Slim and Secure Container Images with Slim.ai

DevOps and Docker Talk 14 October 2022

Episode Description

Bret is joined by Martin Wimpress and Pieter van Noordennen from Slim.ai to discuss some ways to slim down your Docker images and reduce the attack surface of your containers in the process.


Many companies and projects have tried to do similar things before - Slim Images, Alpine Images, Distro List, Build Packs, and even Docker tried a few years back, to create intelligence and guidance around migrating legacy apps into slim production quality images. Those efforts were scrapped in 2019. The dual mandate of generating Docker images - easy to understand and as minimal as possible, with the lowest CVE vulnerability count - was not achieved by any of those projects.
 

Automation and intelligence like Slim.ai is the future of building container images and also the future of complex monoliths and legacy apps with a lot of dependencies.

Kubescape Kubernetes Security with ARMO

Kubescape Kubernetes Security with ARMO

Bret is joined by Shauli Rozen, CEO and Co-Founder of ARMO, creators of Kubescape. Kubescape is a K8s open-source tool providing a multi-cloud K8s single pane of glass, including risk analysis, security compliance, RBAC visualizer, and image vulnerability scanning. I'm a fan of tools like this and specifically of Kubescape, which I use and recommend to my clients. The scanner can scan your YAML manifests of your Kubernetes resources. It can scan your live Kubernetes clusters. And it can scan the YAML in your Git repos, as well as the images themselves that you're deploying to Kubernetes. As ARMO calls it, it's a single pane of glass into your Kubernetes security.   Streamed live on YouTube on September 1, 2022. Includes demos.

Argo CD Past & Future, with the Creators

Bret is joined by the co-creators of the Argo project and co-founders of Akuity - Hong Wang and Jesse Suen - to discuss the state of Argo and their new Akuity offering for Argo CD in the Cloud. Chances are, you've heard of one or more of the Argo projects. They include Argo Workflows, Argo CD, Argo Events, and Argo roll-outs. Argo is one of those Kubernetes projects that is so common for teams to choose that it's nearly an assumption that every team is using one of their tools in a cluster or two. Hong Wang and Jessie Suen helped co-create the Argo project years back at Intuit and have now co-founded a growing startup called Akuity. The company is focusing on making the Argo products better and creating SaaS offerings for the Argo tools. In this episode, we get a perspective on where the Argo tools came from and what the team behind it is doing. Streamed live on YouTube on May 26, 2022.

Infrastructure as Code, Patterns and Practices

Infrastructure as Code, Patterns and Practices

Bret is joined by Rosemary Wang, a developer advocate at Hashi Corp. She recently finished a Manning book, titled Infrastructure as Code: Patterns and Practices. They discuss how infrastructure as code fits into DevOps and Gitops, and how you can get started with IaC and run over some important patterns, such as controlling versioning, IaC testing and managing costs. Rosemary worked at ThoughtWorks previously, and it was interesting to hear her experiences on learning from senior engineering, and how pairing and other types of mentorship can help.

Applications-as-Code with Shipa

Applications-as-Code with Shipa

Bret is joined by Ravi Lachhman, Field CTO at Shipa, to discuss the basics of Shipa application and policy management, and show off the developer experience that Shipa brings to apps running on IaC and GitOps tools like ArgoCD,  Crossplane, Terraform, Kubernetes, and more. Shipa is focused on the layer above the infrastructure where application developers can avoid other Kubernetes manifest tools like Helm or Kustomize, and create a cleaner contract between what their application needs are and how the infrastructure provides them. If you've done Kubernetes YAML long enough, you know that it can get quite complex and verbose, and it requires both infrastructure and developer roles or knowledge to fully configure it. So you kind of got to know both worlds. But Shipa wants to fit in the middle somewhere, not replacing the infrastructure tools like Terraform or Crossplane, but rather working on top of them, providing an easier way to describe your apps from a dev's point of view and how they work on top of your infrastructure. It focuses on the application requirements, not necessarily how those requirements are implemented. Streamed live on YouTube on April 14, 2022.

Jim Bugwadia joins Bret to discuss Kubernetes policy management and "intelligent guardrails for K8s." Jim is the CEO and co-founder of Nirmata. He's also the founder of Kyverno, an CNCF Sandbox Project and open source project for managing policies in Kubernetes. We talk about what Kyverno is, what it isn't, and what problems it solves. We also talk a bit about Narmada and how it expands on that. If you're in a team using Kubernetes together, controlling settings and standards in your workloads and clusters can be a constant source of frustration unless you have something to govern those policies across all your workloads and clusters.Streamed live on YouTube on Feb 24, 2022. Unedited live recording of the complete show on YouTube (Ep #160). Includes demos. ★Topics ★ Kyverno is a policy engine designed for Kubernetes. With Kyverno, policies are managed as Kubernetes resources, and no new language is required to write policies. This allows using familiar tools such as kubectl, git, and kustomize to manage policies. Kyverno policies can validate, mutate, and generate Kubernetes resources plus ensure OCI image supply chain security.

Serverless Docker and Kubernetes in 2020

Serverless Docker and Kubernetes in 2020

I answer some audience questions about serverless, and the future of containers... when a lot of the news out there is talking about functions as a service as "the future of everything".  As usual, the answer is "it depends", but if you're a team that's already doing microservices and containers, and you're looking to deploy smaller features faster and cheaper, then serverless might help. For most of us though, writing and shipping functions only, rather than traditional applications, is years away, because we have bigger problems to solve first, like speeding up our deployment processes or improving our monitoring and recovery.
