Episode notes
Bhavin's Acadia Camping
- Bhavin Shah shared a story about camping and hiking at Acadia National Park, including adjusting plans for falcon nesting season.
- Ryan Wallner contrasted this with his family birthday celebration and golfing during the COVID era.
Why Containers Need Storage
- Containers are ephemeral but applications often need persistent storage to retain state across restarts.
- Kubernetes provides persistent storage so data survives pod restarts or recreation on different hosts.
Docker Volumes Origins
- Docker introduced volumes to enable data persistence outside ephemeral containers.
- HostPath volumes mapped host filesystem paths into containers but without orchestration or scalability.
