HYPERFLEET-1483 - fix: route adapters through hyperfleet-gateway instead of hyperfleet-api

[mliptak0]

Summary

• HYPERFLEET-1483
• Envoy Gateway + NetworkPolicies now block direct pod-to-pod access to hyperfleet-api; all traffic must go through hyperfleet-gateway. Updates the E2E adapter deployment and adapter-config testdata to route through the gateway instead.
• Removes the dynamic hyperfleet-api Service lookup (resolveInternalAPIURL) in favor of a ADAPTER_HYPERFLEET_API_URL env var (defaulting to http://hyperfleet-gateway:8000), kept intentionally separate from HYPERFLEET_API_URL since that one points at wherever the e2e test process itself reaches the API (port-forward/external LB) and is not routable from in-cluster adapter pods.
• Updates the 6 testdata/adapter-configs/*/adapter-config.yaml fixtures that hardcoded http://hyperfleet-api:8000 as clients.hyperfleet_api.base_url to use http://hyperfleet-gateway:8000.

Test Plan

• Unit tests added/updated
• make test-all passes
• make lint passes
• Helm chart changes validated with make test-helm (if applicable)
• Deployed to a development cluster and verified (if Helm/config changes)
• E2E tests passed (if cross-component or major changes)

📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Added configurable HyperFleet API connectivity through an environment setting, with a reliable in-cluster default.
  • Updated adapter configurations to use the HyperFleet gateway endpoint.

• Bug Fixes

  • Improved adapter deployment connectivity by consistently passing the resolved HyperFleet API URL to deployments.

Walkthrough

The adapter now reads ADAPTER_HYPERFLEET_API_URL and falls back to http://hyperfleet-gateway:8000. It passes the resolved URL to Helm through adapterConfig.hyperfleetApi.baseUrl. Kubernetes service-based URL resolution and its tests were removed. Adapter test configurations now use hyperfleet-gateway.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 4f78b

The adapter deployment now accepts its API endpoint through Helm, but URLs containing commas or backslashes may be parsed incorrectly, potentially causing deployment failure or incorrect configuration. The PR is otherwise mergeable with explicit owner awareness or follow-up on safe value escaping.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 2 files. (6 skipped: 6 unsupported.)

Full details: Sec-02: Secrets In Log Output

Explanation

No SEC-02 failure was introduced. The production diff adds no slog, log, logr, zap, or fmt.Print* statement. The existing logger.Info("executing Helm command", "args", helmArgs) now receives a non-secret API base URL and contains no token, password, credential, or secret field. The removed log statements only logged an API URL or an error. This does not meet CWE-532 criteria.

Full details: No Hardcoded Secrets

Explanation

No hardcoded secret was introduced. The only new literal is http://hyperfleet-gateway:8000, which contains no credentials. ADAPTER_HYPERFLEET_API_URL is read from the environment, not assigned a secret literal. The six changed URLs are test fixtures and contain no credentials or long base64 strings. No CWE-798 hardcoded-credential condition or CVE is applicable.

Full details: No Weak Cryptography

Explanation

PASS. The pull request adds URL configuration and removes Kubernetes service lookup. The added lines contain no crypto/md5, crypto/des, crypto/rc4, SHA-1, ECB, custom cryptography, or secret comparisons. Existing crypto/rand and crypto/sha256 usage in pkg/helper/adapter.go is unchanged and does not match the banned primitives. No CWE or CVE is applicable.

Full details: No Injection Vectors

Explanation

CWE-78: pkg/helper/adapter.go:178-180 reads ADAPTER_HYPERFLEET_API_URL directly from the process environment, with no URL or delimiter validation. The changed code concatenates that value into a Helm --set argument at line 224 and passes it to exec.CommandContext at line 237. exec.CommandContext avoids shell metacharacter expansion, but Helm parses the argument as its own --set expression; a value containing Helm delimiters such as , can inject additional chart values. The default constant and hardcoded fixture URLs are trusted, but the new environment override is not provably trusted.

Resolution

Validate ADAPTER_HYPERFLEET_API_URL before use with strict URL rules, including an allowed scheme, host, and rejection of control characters. Do not place the raw value in Helm's --set grammar. Serialize the validated URL as a scalar in a temporary values file and pass that file with -f, or apply a rigorously tested Helm escaping routine. Add tests for commas, equals signs, backslashes, newlines, invalid URLs, and option-like input.

Full details: No Privileged Containers

Explanation

No failure condition was introduced. The pull request changes only Go source, tests, and six adapter test fixtures. No Kubernetes manifest, Helm template, or Dockerfile changed, and no added line contains privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or runAsUser: 0. The existing USER root lines in Dockerfile and images/Dockerfile are identical in HEAD^ and HEAD. No CWE/CVE applies to this change.

Full details: No Pii Or Sensitive Data In Logs

Explanation

PASS. The pull request adds no logging of PII, session IDs, or raw request/response bodies. The existing Helm-argument log now includes the resolved API URL, but the introduced default is the credential-free internal URL http://hyperfleet-gateway:8000. No credential-bearing URL is introduced by the changed code. No CWE/CVE applies.
