🔗 Kubernetes 1.28: Native Sidecar Containers
Title: Making Sense Out of Native Sidecar Containers in Kubernetes – Oct. 2023
Description: Kubernetes 1.28 has introduced a new concept known as "native" sidecar containers, which serve as a more efficient and flexible way to handle auxiliary functionality within Pods. These native sidecar containers are essentially init containers with a specific attribute, allowing them to start before regular containers, respect their own restart policy, and support probes. This design provides a clever and future-proof solution for managing auxiliary functionality such as network proxies, monitoring agents, and data transformers, making it easier to keep them outside the main application container while still residing in the same Pod.
