Multi-Container Pods (Sidecars)
Explore patterns for running multiple co-located containers within a single Pod, like sidecar containers.
Beyond a Single Container
So far, we've thought of Pods as running a single container. But what if your application needs a helper process?
Kubernetes allows a Pod to run multiple containers. These containers are always co-located and share resources.
Why Multi-Container Pods?
Running multiple containers in one Pod is ideal for applications that are tightly coupled and need to share:
- Network namespace (same IP address, can communicate via
localhost) - Storage volumes
- Lifecycle (they start, stop, and restart together)
This allows for a single unit of management for related processes.
