Master Kubernetes with this a 4-day Advanced Kubernetes workshop on the 22nd of September (in 2 weeks)!

_What should you expect?_

- Learn how to architect and design clusters from the ground up (in the cloud or on-prem).
- Explore the Kubernetes internal component and how the system is designed with resiliency in mind.
- **Deep-dive into the networking components and observe the packets flowing into the cluster.
- Hands-on labs to test the theory with real-world scenarios!

What happens if an attacker accesses your Prometheus server?

How much information can they get for fingerprinting the cluster?

In this article, you will learn how attackers use this information and how to secure your cluster.

This article will look into how you can secure Ingress resources via adding TLS to Ingress and then procuring TLS/SSL certificates.

In this article you will explore how users and workloads are authenticated with the Kubernes API server.

Reducing infrastructure costs boils down to turning apps off when you don't use them.

However, the challenge is figuring out how to turn them on automatically when needed.

Take the example of a Kubernetes dev cluster: you might want not to run any service during the weekend.

In this webinar, Salman will demo live how you can use KEDA and the HTTP scaler to intercept and monitor the requests to your services and scale your pods accordingly.

In the process, you will discover how you can scale to zero and create pods only when you need them.

In this article, you will learn about Kubernetes security and architecture by reviewing reports from Chekov — a tool designed to find misconfigurations before they’re deployed.

Over 900k Kubernetes exposures were observed across the internet during a routine threat-hunting exercise.

While this does not imply that all exposed instances are vulnerable to attacks, it still makes them a target.

You can learn more in this report.

All unpatched versions of Argo CD starting with v1.3.0 are vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive YAML files from Argo CD's repo-server.

Secrets in Kubernetes are used to store sensitive information.

This blog post will show how to secure Kubernetes secrets using the Hashicorp vault.

Switchboard is a Kubernetes operator that automates the creation of DNS records and TLS certificates when using Traefik v2 and its IngressRoute custom resource.

When your Kubernetes cluster runs low on resources, the Cluster Autoscaler provision a new node and adds it to the cluster.

The cloud provider has to create a virtual machine from scratch, provision it and connect it to the cluster.

The process could take more than a few minutes from start to end.

But there's an alternative: you can proactively create nodes that are already provisioned when you need them.

In this webinar, Chris will demo live how you can configure Pod Priorities and a placeholder pod to pre-warm node instances for quicker scaling.

All versions of Argo CD starting with v1.0.0 are vulnerable to a cross-site noscripting (XSS) bug allowing a malicious user to inject a javanoscript: link in the UI.

More: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-31035

In this article, you will learn why PodSecurityPolicies never made it as a GA feature, why they had to be replaced and what you should consider going forward.

In an affected version of KubeEdge a malicious message can crash CloudCore by triggering a nil-pointer dereference in the UDS Server.

This bug has been fixed in Kubeedge 1.11.0, 1.10.1, and 1.9.3.

In this article, you will explore how OpenShift provides a powerful mechanism to enhance the security of your AWS account by using short-lived credentials through STS, instead of static User credentials (Access Keys).

This article focuses on how Teleport can be used to give developers secure access to a Kubernetes cluster.

One interesting challenge with Kubernetes is deploying workloads across several regions.

While you can technically have a cluster with several nodes located in different regions, this is generally regarded as something you should avoid due to the extra latency.

Another popular alternative is to deploy a cluster for each region and find a way to orchestrate them.

In this webinar, Daniele will demo live how to create, connect and operate three Kubernetes clusters in different regions.

In this tutorial, you'll learn how to use Kyverno to automatically configure annotations that enable access logs for an AWS Network Load Balancer (NLB) to be forwarded to an S3 bucket for a service of type LoadBalancer.
