It describes common deployment patterns and shows how to deploy the sandbox on GKE with Pulumi. ### Source excerpt When you use a coding agent, it can seem like there's a trade-off between autonomy and permissions. If you approve every command, it's safe but slow. Let it do whatever it likes and it works more autonomously, but as the nx supply-chain attack showed, that can go badly. The fix is to give the agent a sandbox: a box it's allowed to wreck, with limited permissions and scoped network access. The only files are the checkout you handed it, the only credentials are the task's own, and trashing the machine just means a disposable pod gets garbage-collected early. Pulumi Neo works this way, and if you want to scale that pattern up inside your own organization, the Kubernetes project Agent Sandbox is a great path to building your own. This post is what it is and how to deploy it on GKE with Pulumi. What is Agent Sandbox? Agent Sandbox is a Kubernetes SIGs project that gives AI agents isolated, disposable environments as Kubernetes resources: a Sandbox custom resource, backed by gVisor or Kata Containers for kernel-level isolation. You could build Agent Sandbox yourself. You'd need gVisor support, a userspace kernel that sits between the agent's code and your host. With that in place, you could approximate a sandbox for every agent by stringing together a StatefulSet of size one, a headless Service, and a PersistentVolumeClaim, plus some lifecycle machinery to keep warm pools of nodes around. Agent Sandbox wraps all of that up as a CRD, so you can run a Kubernetes cluster where each sandbox is a disposable, kernel-isolated environment a coding agent runs in. apiVersion: agents.x-k8s.io/v1beta1 kind: Sandbox metadata: name: demo-sandbox spec: podTemplate: spec: runtimeClassName: gvisor containers: - name: agent image: ubuntu:24.04 # swap in your coding-agent image command: ["sleep", "infinity"] The Sandbox CRD, the whole idea in one manifest. There are two common patterns for using it.

OpenRL is a self-hosted training API for fine-tuning LLMs on a Kubernetes cluster, designed to separate post-training infrastructure from AI research workflows. The article describes potential benefits including concurrent reinforcement-learning jobs, improved GPU utilization, and simpler researcher workflows. ### Source excerpt by Sunil Arora, Shuby Mishra & Chuang Wang, GKE We are pleased to share a research preview of OpenRL, a new open-source project coming out of GKE Labs. OpenRL is a self-hosted training API for fine-tuning LLMs on your own Kubernetes cluster. Why we built it If you look at agentic RL on LLMs, it is incredibly easy to get bogged down in system complexity. To run a single RL loop, you have to coordinate a dozen different things: selecting and cleaning datasets, choosing RL environments, debugging training loops, managing reward signals, handling inference mismatches, allocating hardware, and managing infrastructure. Picture looks something like this: Figure shows an AI researcher and an infrastructure engineer staring at the hurdles in post training along the way to the summit. Each of these is a hard problem. But what makes it more complex is how tightly AI research and infrastructure concerns are mixed together in today's tooling and frameworks. We believe decoupling the infrastructure from AI research can make these problems more tractable so that infrastructure engineers and AI researchers can independently tackle them. We have seen this pattern with Kubernetes where Kubernetes abstracted out the infrastructure and made application developers and SREs life easier. So, can you abstract out post training infrastructure? We believe so and drew huge inspiration/validation from Tinker (from Thinking Machines). The Tinker APIs for post training hit that Goldilocks zone where it hides all the post training infrastructure behind four key APIs: Figure shows high level components and their interaction in a OpenRL based RL workflow So the end result of this abstraction is that AI Researchers get full flexibility on their RL loop and infrastructure engineers can focus on scaling, orchestration, and reliability. OpenRL allows you to run the same training APIs but on your own infrastructure. And this decoupling has other interesting benefits.

It also notes experimental plugin and engine features and invites community feedback. ### Source excerpt What happened in Falco this week? Let's go through the major changes that happened in various repositories under the falcosecurity organization. Libs Libs will need a 0.14.2 tag for the Falco 0.37.0 release, with the revert of https://github.com/falcosecurity/libs/pull/1533 PR. During our release process, we found out that the new std::filesystem based implementaton was up to 8x time slower than the old ones; that's because it supports much more cases and does many more checks. Therefore, in https://github.com/falcosecurity/libs/pull/1645, we revert to the old sorcery implementation, plus some minor improvements and added tests. Moreover, many more changes landed in libs, that won't be part of the upcoming Falco 0.37.0 release: Modernized C++ struct/enum/union declarations: https://github.com/falcosecurity/libs/pull/1588 Added support for newfstatat syscall: https://github.com/falcosecurity/libs/pull/1628 Fixed a potential deadlock for kmod: https://github.com/falcosecurity/libs/pull/1629 Big effort by our hero, Jason, to cleanup some stale macros: https://github.com/falcosecurity/libs/pull/1633,https://github.com/falcosecurity/libs/pull/1634,https://github.com/falcosecurity/libs/pull/1635,https://github.com/falcosecurity/libs/pull/1637,https://github.com/falcosecurity/libs/pull/1638 A small fix for old ebpf driver to support some GKE envs: https://github.com/falcosecurity/libs/pull/1642 Solved a data race and segfault in logger: https://github.com/falcosecurity/libs/pull/1643 Allow to selectively disable bpf and kmod engines from cmake: https://github.com/falcosecurity/libs/pull/1644 Falco Falco tag 0.37.0-rc2 is out!

It describes Falco's syscall monitoring, its use of Kubernetes and container-runtime context, example security rules, installation through Google Cloud Marketplace or Helm, and constraints involving Autopilot, privileged containers, and eBPF drivers. ### Source excerpt One of the big advantages of running your workloads on a managed Kubernetes service like Google Kubernetes Engine (GKE) is that Google ensures your clusters are being deployed and managed following industry best practices. While GKE clusters are incredibly secure and reliable, there is always room for improvement. In this blog, we're going to describe how you can enhance GKE's already great security by adding runtime threat detection with Falco. What is Falco? Falco is a Cloud Native Computing Foundation project that provides runtime threat detection. Out of the box, Falco examines syscalls to alert you to any suspicious activity. And, since containers share the same kernel as their host, Falco can monitor not only activity on the host but also activity on all of the containers running on that host. Moreover, Falco pulls data from both Kubernetes and the container runtime to add additional context to its alerts. With Falco running on your GKE clusters you can be notified of a wide variety of events, such as: Did someone start a container with high privileges? Has someone shelled into a running container? Has an executable been added to the container after it was deployed? These are just a few examples. Falco has over 80 rules that can be used to make you aware of not only external threats but also when clusters aren't being operated in accordance with industry best practices. GKE Installation considerations There are two different ways to install Falco on GKE. The first is using the prepackaged click-to-run offering in the Google Cloud Marketplace. The second is using Falco's helm chart. The click-to-run offering is probably the simplest way to get up and running with Falco on GKE, but the drawback is that the version offered often lags behind the latest release. It's also important to note that as of this writing, you cannot run Falco on GKE clusters running in Autopilot mode. This is primarily because Falco uses an init container running with privileged access to ## How trivago Maintains Global Availability During a Google Cloud Regional Outage DevFeed: [How trivago Maintains Global Availability During a Google Cloud Regional Outage]() Original publisher: [Read original article]() Author: Arne Claus Follow Published: 2022-08-15T00:00:00Z Content type: tutorial Language: en Sources: [Trivago]() Topics: [Google Cloud Platform (GCP)](), [Kubernetes](), [Kafka](), [migration](), [Back end](), [sharding](), [Replication](), [systems](), [MySQL]() Tags: [backend](), [cloud](), [datacenters](), [failover](), [gke](), [google-cloud](), [how-to](), [kafka](), [migration](), [mysql](), [replication](), [sharding](), [systems]() ### AI overview This article explains trivago's regional failover testing and its effort to maintain global availability when a Google Cloud region becomes unavailable.

GCLB provides a single anycast IP that fronts all of your backend compute instances along with a lot of other rich features. In order to create a GCLB that uses HTTPS, an SSL certificate needs to be associated with the ingress resource. This certificate can either be self-managed or Google-managed. The benefit of using a Google-managed certificate is that they are provisioned, renewed, and managed for your domain names by Google. These managed certificates can also be configured directly with GKE, meaning we can configure our certificates the same way we declaratively configure our other Kubernetes resources such as deployments, services, and ingresses. ## GKE using Traefik as the ingress controller DevFeed: [GKE using Traefik as the ingress controller]() Original publisher: [Read original article]() Author: Carlos Alexandro Becker Published: 2020-02-02T00:00:00Z Content type: tutorial Language: en Sources: [Carlos Becker]() Topics: [Gke](), [traefik](), [Kubernetes](), [Cloudflare]() Tags: [cloudflare](), [gke](), [ingress](), [kubernetes](), [load-balancer](), [traefik]() ### AI overview The article explains how using Traefik as the ingress controller in a GKE Kubernetes cluster caused intermittent Cloudflare HTTP 520 errors. A load balancer sent traffic to preemptible nodes that did not run Traefik; if a node was preempted during a slow request, the request ended prematurely. The proposed fix is to configure load-balancer health checks so only nodes running Traefik receive traffic. ### Source excerpt I recently fell into a trap using Traefik as the ingress controller in one cluster. I decided to write about it with hopes it maybe help someone else. ## Authenticate against GKE without gcloud DevFeed: [Authenticate against GKE without gcloud]() Original publisher: [Read original article]() Author: info@goteleport.com (Emanuele Calo) Published: 2018-10-03T00:00:00Z Content type: tutorial Language: en Sources: [Teleport]() Topics: [Kubernetes clusters](), [Authentication](), [Kubernetes](), [CI/CD]() Tags: [authentication](), [ci-cd](), [cloud](), [gke](), [kubernetes]() ### AI overview A tutorial explaining how to authenticate to Kubernetes clusters running on Google Kubernetes Engine without installing gcloud.
