Description

Implement a NAVER Cloud Platform provider for the Brev Cloud SDK that can create and manage cloud VM/server instances through NAVER Cloud Platform's VPC Server APIs. Use the official Naver API documentation as the source of truth, starting from https://api.ncloud-docs.com/docs/en/api-overview and the VPC Server create/list/detail/terminate endpoints.

Acceptance criteria:

• Add a provider package under v1/providers for NAVER Cloud Platform following existing provider conventions.
• Support credential validation/signing for NAVER's NCP Signature V2 headers using access key and secret key.
• Implement VM/server instance create, get/list, terminate/delete, and instance type/location/image discovery behavior to the extent the SDK interfaces require.
• Use Naver VPC Server APIs such as /vserver/v2/createServerInstances, /getServerInstanceList, /getServerInstanceDetail, /terminateServerInstances, and catalog/list endpoints.
• Add focused unit tests for request signing, request construction, response parsing/state mapping, validation, and lifecycle behavior using fake HTTP servers where possible.
• Do not require real NAVER credentials or network calls in unit tests.

Plan

Files to change

• v1/providers/naver/client.go - add credential/client construction, options for tests, NCP Signature V2 request signing, shared request/response handling, and provider identity.
• v1/providers/naver/capabilities.go - declare supported NAVER VM lifecycle capabilities.
• v1/providers/naver/location.go - implement region discovery from /vserver/v2/getRegionList.
• v1/providers/naver/image.go - implement image discovery from /vserver/v2/getServerImageProductList.
• v1/providers/naver/instancetype.go - implement instance type discovery from /vserver/v2/getServerProductList.
• v1/providers/naver/instance.go - implement import login key, create, get, list, terminate, reboot, stop, start, conversion, and status mapping.
• v1/providers/naver/*_test.go - add fake-server unit coverage for signing, request construction, response parsing, filters, and status conversions.

New files

• v1/providers/naver/client_test.go - verifies NCP Signature V2 and auth headers.
• v1/providers/naver/instance_test.go - verifies create/get/list/terminate behavior and lifecycle mapping.
• v1/providers/naver/instancetype_test.go - verifies catalog conversion and filtering.
• v1/providers/naver/location_test.go - verifies region conversion.
• v1/providers/naver/image_test.go - verifies image conversion and filtering.

Database changes

• None.

Implementation steps

1. Add failing unit tests using httptest.Server; ensure no real NAVER credentials or network calls are required.
2. Add NaverCredential and NaverClient with provider ID naver, global API type, default base URL https://ncloud.apigw.ntruss.com, and deterministic tenant ID derived from the access key.
3. Implement a small HTTP transport helper that signs the path plus encoded query string using NAVER's Signature V2 format: METHOD + "\n" + pathWithQuery + "\n" + timestamp + "\n" + accessKey, HMAC-SHA256 with secret key, Base64 encoded.
4. Implement typed response structs for the VPC Server endpoints needed by the SDK, always requesting responseFormatType=json and treating non-zero NAVER return codes as errors.
5. Map SDK create attributes into NAVER create parameters: regionCode, vpcNo, subnetNo, image code/no, server product/spec code, name, user data, key pair/imported login key, and network interface order 0.
6. Convert NAVER server instances into v1.Instance, preserving cloud IDs, names, status, IPs, image/product codes, VPC/subnet, location, disk, SSH defaults, and stable instance type IDs.
7. Implement catalog/list methods with SDK filters for locations, image IDs, architectures, and instance type names.
8. Run the focused NAVER tests, then make test; format with gofmt.

Test command

go test ./v1/providers/naver for red/green on the new provider, then make test for repository verification.

Risks / notes

• NAVER public IP association is a separate API; this first VM lifecycle implementation reports a public IP when NAVER returns one but does not allocate/associate a new public IP.
• NAVER VPC creation requires existing VPC/subnet identifiers through CreateInstanceAttrs.VPCID and CreateInstanceAttrs.SubnetID.
• Some NAVER GPU product metadata is encoded in product codes/descriptions; conversion uses explicit API fields when available and conservative parsing for GPU hints.

Tests to Write

• v1/providers/naver/client_test.go - auth header/signature generation and credential client construction.
• v1/providers/naver/location_test.go - region endpoint conversion into SDK locations.
• v1/providers/naver/image_test.go - image product conversion and architecture/id filtering.
• v1/providers/naver/instancetype_test.go - server product conversion, GPU parsing, location/type filtering, and stable IDs.
• v1/providers/naver/instance_test.go - login key import, server create request mapping, instance conversion, get/list/terminate flows.

Test Results (Red)

Command: go test ./v1/providers/naver

Result: blocked before compilation because go is not installed/on PATH in this shell (/usr/bin/bash: line 1: go: command not found). The tests are present and currently precede implementation.

Implementation Notes

Tests written

• v1/providers/naver/client_test.go - verifies NCP Signature V2 headers/signature and credential client construction.
• v1/providers/naver/location_test.go - verifies region list conversion into SDK locations.
• v1/providers/naver/image_test.go - verifies image product conversion and filtering.
• v1/providers/naver/instancetype_test.go - verifies server product conversion, GPU parsing, filtering, and stable IDs.
• v1/providers/naver/instance_test.go - verifies login key import, create request mapping, detail/list/terminate flows, and lifecycle status mapping.

Red phase

Tests written, confirmed failing: YES
Failure reason: the first red command could not compile because the repository shell had no go binary on PATH. A temporary Go 1.25.1 toolchain was then downloaded under /tmp/go1.25.1 for verification.

Changes made

• v1/providers/naver/client.go - added NAVER credential/client, test options, NCP Signature V2 signing, and shared JSON request handling.
• v1/providers/naver/capabilities.go - declared VM lifecycle, stop/start, reboot, and image capabilities.
• v1/providers/naver/location.go - added getRegionList location discovery.
• v1/providers/naver/image.go - added getServerImageProductList image discovery.
• v1/providers/naver/instancetype.go - added getServerProductList instance type discovery and conservative GPU parsing.
• v1/providers/naver/instance.go - added login key import, create, detail get, list, terminate, reboot, stop/start, and SDK instance conversion.

Green phase

Focused tests passing: YES
Command: PATH=/tmp/go1.25.1/bin:$PATH go test ./v1/providers/naver

Full suite: BLOCKED by existing environment-sensitive SSH test
Command: PATH=/tmp/go1.25.1/bin:$PATH make test
Failure: internal/ssh Test_GetPublicIP cannot reach https://api.ipify.org from this environment (connection reset by peer). The NAVER provider package passes.

Build

Not separately run; go test ./v1/providers/naver compiles the new package.

Notes

• Existing .gitignore modifications were present before this work and are intentionally left unstaged.

Review

Diff summary

• Files changed: 11 new NAVER provider files
• Lines added: about 1.2k in the new provider package and tests
• Matches plan: YES
• Tests present: YES

Issues found

• None in the NAVER provider diff. Full-suite verification is blocked by the unrelated internal/ssh Test_GetPublicIP network dependency.
