Add cleanup for dpf scoped service interfaces - #5045
Conversation
Signed-off-by: aadvani <aadvani@nvidia.com>
Summary by CodeRabbit
WalkthroughInitialization now deletes stale opposite-mode ServiceInterfaces, waits for deletion, and creates replacement resources. Kubernetes deletion is idempotent for missing resources. Tests cover BF4 initialization and both migration directions. Configuration documentation describes cleanup and failure behavior. ChangesServiceInterface migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The migration cleanup can delete unscoped DPUServiceInterface resources that NICo did not create, potentially disrupting unrelated services during initialization. The current head is unsafe to merge until deletion is restricted to NICo-owned interfaces. Sequence Diagram(s)sequenceDiagram

The mock removes the entry synchronously.
wait_for_service_interface_deletiontherefore observesNoneon its first poll in every test, so neither the polling loop nor the 60-second timeout path is exercised. Kubernetes deletion is asynchronous, and the wait loop is the core mechanism this PR adds.Add a mock mode that keeps the resource visible for a configurable number of
getcalls afterdelete. That mode lets one test assert the loop waits for confirmed removal, and a second test assert aDpfError::Timeoutsurfaces as anInvalidStateinitialization failure.As per path instructions: "Prefer findings about behavior, concurrency, resource lifetimes, and missing tests over style-only comments."

Restrict legacy cleanup to NICo-owned interfaces.
delete_stale_legacy_service_interfaces lists every DPUServiceInterface in the namespace and deletes each one whose node_selector is None. There is no name, label, or ownership filter. Any DPUServiceInterface in the DPF namespace that NICo did not create is deleted during a scoped migration, provided it carries no node selector.
Compare the scoped path at Line 1640: that path gates deletion on the -bf3/-bf4/-astra suffix, so it never touches foreign resources. The legacy path has no equivalent gate.
Gate deletion on NICo ownership. The apply implementation in crates/dpf/src/repository/kube.rs already uses the carbide-dpf-sdk field manager, so a NICo-applied label on the interface template is the natural marker. A name-inventory check against the effective interface list is an acceptable alternative.
Note that the new test at crates/dpf/src/test/sdk_initialization.rs Line 1039 seeds c2pf3 from a superseded intercept inventory and asserts its removal. Any ownership filter must still delete that resource, so a label or field-manager marker is preferable to a strict current-inventory match.

This change adds cleanup associated with deployment_scoped_service_interfaces.
When scoped mode is enabled, NICo removes the existing unscoped interfaces and creates the scoped -bf3, -bf4, or -astra versions. When scoped mode is disabled, it removes the scoped versions and restores the legacy unscoped set.
NICo waits for each deletion before applying replacements, so the two interface generations do not overlap. If cleanup or creation fails, there is no rollback, and initialization fails with an error explaining that the operator should fix the issue and retry.
The diff also adds the repository delete operation, updates the configuration documentation, and adds migration-focused test coverage.
