K3s and Kubernetes CronJobs can keep showing 'Succeeded' while quietly not running for weeks. Here's how concurrencyPolicy, startingDeadlineSeconds, the 100-missed-schedule limit, and exit code 0 combine to create silent failures, and how to monitor for it.
You can't know how resilient your production K3s environment really is until something actually breaks. Monitoring and alerting only detect failure after the fact. This guide covers how to get started with chaos engineering using CNCF's LitmusChaos on K3s, and how to judge which workloads are safe to break first and which ones demand extra caution.
World Cup broadcasts duplicate every camera feed across two independent paths and simply discard whichever packet arrives second. That seemingly wasteful design shares the same philosophy as Kubernetes high availability and multi-AZ architecture.
Kubernetes high availability isn't achieved simply by adding more replicas. Using the broadcast industry's SMPTE ST 2022-7 dual-path transmission as a lens, this article unpacks what Topology Spread Constraints and multi-AZ design actually mean.
