refactor(api): remove SandboxTemplate.volume_claim_templates#2088
Merged
Conversation
The field was added during the Kubernetes driver extraction refactor (#817) as a pass-through mechanism, but was never wired up to a CLI flag, Python SDK helper, or any documentation. The only reachable user path was raw gRPC construction. The Kubernetes driver now always injects the default workspace PVC, removing the branching logic that checked for a user-supplied VCT. Field number 9 is reserved in the proto to prevent reuse. Signed-off-by: Evan Lezar <elezar@nvidia.com>

Summary
Remove
SandboxTemplate.volume_claim_templatesfrom the public API. The field was added during the Kubernetes driver extraction refactor (#817) but was never surfaced to users — no CLI flag, no Python SDK helper, no documentation. The only way to reach it was raw gRPC construction.The Kubernetes driver now unconditionally injects the default workspace PVC, removing the branching logic that existed to accommodate user-supplied VCTs. Field number 9 is reserved in the proto to prevent future reuse.
See also #2034 (feat(kubernetes): support PVC subPath driver config), which covers the supported path for PVC customisation via driver config.
