A tool for importing secrets from a pre-existing secrets management systems (e.g. Vault, Secrets Manager) into a SealedSecret.

Robusta KRR (Kubernetes Resource Recommender) is a CLI tool for optimizing resource allocation in Kubernetes clusters. It gathers pod usage data from Prometheus and recommends requests and limits for CPU and memory. This reduces costs and improves performance.

In modern cloud-native environments, Kafka consumers are increasingly deployed within Kubernetes. This setup offers benefits in scalability and deployment ease but also introduces the need for sophisticated scaling strategies that can adapt to the volatile nature of Kafka’s data streams.

Kubernetes schedules GPU workloads by assigning a whole device to a single job exclusively. This one-to-one relationship leads to massive GPU underutilization, especially for interactive jobs, characterized by significant idle periods and infrequent bursts of heavy GPU usage. Current solutions enable GPU sharing by statically assigning a fixed slice of GPU memory to each co-located job. These solutions are not suitable for interactive scenarios since the number of co-located jobs is limited by the size of physical GPU memory. Consequently, users must know the GPU memory demand of their jobs before submitting them for execution, which is impractical.

Understand Kubernetes Events and learn to use kubectl events to monitor and troubleshoot your cluster’s issues effectively.

The nuances of how users and groups are configured in Kubernetes and how the role-based access control (RBAC) mechanism applies for them.

Argo Event is a Kubernetes based event automation engine. It is part of the Argo project. Argo Events can be used with or independent of other projects in Argo.

I will be writing a series of articles on Argo Events; in these articles I will be looking at how we can use Argo Event to automate process within and without a Kubernetes cluster.

For this first article in this series, we will examine Argo Events core concepts, installation and provisioning different event buses which Argo Event uses to forward events to their sink. Finally we will look at setting up a webhook event flow to verify our setup.

Know the differences between ConfigMaps mounted as Volumes and ConfigMaps defined as environment variables.

A database does not need a write-ahead log (WAL) to achieve durability. A database can write its long-term data structure durably to disk before returning to a client. Granted, this is a bad idea! And granted, a WAL is critical for durability by design in most databases. But I think it's helpful to understand WALs by understanding what you could do without them.
