Episode notes
Native Sidecars in Kubernetes
- Kubernetes sidecars lacked a formal API, causing issues like zombie cron jobs and resource conflicts.
- The new native sidecar feature in Kubernetes 1.28, implemented as init containers with restart policy, aims to solve this.
Istio Sidecars and Argo Workflows
- Argo workflows, used for workflow orchestration, faced challenges with Istio sidecars due to increased job execution time.
- Native sidecars offer a better way to handle sidecars in such scenarios where jobs are short-lived.
Sidecars in Data Engineering
- Data engineering teams using Apache Airflow for batch jobs faced similar sidecar issues, particularly with vault integration.
- Native sidecars offer a more seamless solution for managing short-lived jobs that require sidecars for fetching credentials.
