feat: configure Azure AI Foundry and unsupported parameter dropping

[ak684]

The Replicated Admin Console currently only creates azure/ routes, so installs that need both Azure OpenAI and Azure AI Foundry must edit LiteLLM manually. This adds separate or combined provider configuration and an independent drop-unsupported-parameters toggle for each provider. Existing Azure deployment names and the default provider are preserved; Foundry uses separate credentials and explicit azure_ai routing.

End-to-end testing exposed two additional blockers fixed here:

• LiteLLM overwrites AZURE_API_VERSION during startup. Background reconciliation then removes Azure routes whose generated ID changed. Render the configured, nonsecret API version directly into each route to keep it stable.
• Managed conversations need OPENHANDS_PROVIDER_BASE_URL. Set it from the already configured LITE_LLM_API_URL so runtimes use the installation's bundled or external proxy.

Validation:

• 108 provider route, credential checksum, and warm environment regression tests pass; both new managed-proxy Helm tests and both charts' Helm lint pass. All applicable PR CI checks pass.
• Real Azure requests through the 1.100.1 database image pass for both providers, including Responses routing and drop_params behavior.
• Reproduced Azure route deletion after startup's API-version overwrite; the same reconciliation preserves both routes with the rendered version fix.
• Real in-place upgrade on R03: baseline 0.70.2 → initial candidate 0.74.0 → fixed package 0.75.0. Azure settings preserved; all preflights pass; final KOTS sequence 26 / vendor release 1749 is Ready.
• The final package uses the official app 1.68.0 / agent-server 1.50.1 / LiteLLM database 1.100.1 images, with no diagnostic source overlay. Deployed provider URL matches the chart, and Azure remains discoverable after background refreshes.
• Final Azure OpenAI conversation afbc293f1edd41a3ad466158349c8d86 ran Python and returned AZURE_131_OK using azure-upgrade-131 (openhands/azure-gpt-5.3-codex).
• Final Foundry conversation 394c3d20aa28485dae9c7d6d84a053ec ran Python and returned FOUNDRY_131_OK using foundry-upgrade-131 (openhands/azure_ai-gpt-5.4).

Separate app limitation found during testing: creating a new profile with the already selected default model reports "Model is required." Creating with another model and editing to Azure succeeds. This PR does not change that frontend form; the final Azure test used that UI workaround.

Up to date with main as of 2026-10-15 (merged with no conflicts; the scripts tests pass apart from local failures that also occur on main). The live validation above ran on the earlier base. Claude on Foundry and live service-principal authentication have not been tested. Addresses the installer portion of HF #131 / FDE-96; does not cover the ticket's separate budget/custom-parameter requests.

Reviewed against .agents/skills/code-review.md.

The Replicated side looks solid: the existing azure-<deployment> route names and the default model are preserved for upgrades (azure_provider_mode defaults to azure). Foundry gets its own credentials and its own drop_params knob, and the azure_ai- / azure-ai- name collision is covered by a test. Both new secrets are in checksum/litellm-credentials and secretsChecksum, and drop_params changes still roll LiteLLM through the subchart's checksum/config. CI is green. Locally, test_replicated_llm_provider_routes.py passes (76 tests), and so does check_litellm_checksum.py.

I found one important issue in the chart change. It is inline: OPENHANDS_PROVIDER_BASE_URL breaks silently when a consumer overrides LITE_LLM_API_URL through env. The fix is small, so I'm leaving a comment rather than approving for now.

This review was generated by an AI agent (OpenHands) on behalf of the user.

Thanks for the fix! I independently validated release 1749 (0.75.0) on my Azure Replicated install. Azure model discovery remained available across background refreshes, and both an Azure-backed conversation and automation completed terminal commands successfully using the Replicated configuration.

Review of f278d9370aa8087f7d4b6823c98e466a15950944

Reviewed the exact head commit. The PR head is unchanged and matches the requested SHA. No code was modified; this is a review-only pass.

Scope

9 files: two new KOTS config option groups (azure_provider_mode, azure_ai_*, azure_drop_params/azure_ai_drop_params), a rewritten Azure optionalValues block in replicated/openhands.yaml covering api_key / service_principal / Foundry / both, azure_ai secret wiring, OPENHANDS_PROVIDER_BASE_URL in the chart env, checksum updates, and new tests.

Correctness

• Provider coexistence. The single llm_provider=azure block builds both route sets with a shared $seen dict, so azure and azure_ai routes cannot collide, and empty textareas render nothing. Verified for azure, azure_ai, and both modes.
• when gating. azure_provider_mode correctly hides the OpenAI-only fields in azure_ai mode and the Foundry fields in azure mode; azure_auth_method defaults to api_key and resolves empty in azure_ai mode. A stale stored service_principal value does not contaminate azure_ai routes (option hidden ⇒ empty).
• Upgrade preservation. For an existing install (no azure_provider_mode, legacy azure_deployment_name seeded into azure_deployments), the rendered LITELLM_DEFAULT_MODEL stays byte-identical (litellm_proxy/azure-<first>) and route names unchanged (azure-<deployment>). Verified by direct render.
• API-version stability fix. Rendering api_version from the ConfigOption directly (instead of os.environ/AZURE_API_VERSION) keeps generated route IDs stable against LiteLLM's startup overwrite of the env — matches the PR's reproduction claim.
• Secrets/checksums. azure_ai_api_key/azure_ai_endpoint are added to the LiteLLM credentials checksum (27 deps) and the secretsChecksum. Both check_litellm_checksum.py and check_secret_checksum.py pass. The subchart's own checksum/config annotation rolls the LiteLLM pod when model_list/drop_params change, independent of the credentials hash.
• OPENHANDS_PROVIDER_BASE_URL: $(LITE_LLM_API_URL). LITE_LLM_API_URL is always set (bundled FQDN or external litellm.url), so the interpolation resolves either way and Kubernetes $(VAR) expansion is order-independent. The env-var dedup in openhands.env lets consumers override it.
• Foundry routes omit api_version (defaulted client-side by LiteLLM) — consistent with the real-request validation documented in the PR body; not independently reproducible here.

Regression coverage

• scripts/test_replicated_llm_provider_routes.py: 76 pass, incl. the new coexist and foundry-only tests.
• scripts/test_litellm_credentials_checksum.py: 31 pass.
• scripts/test_replicated_llm_key_refresh_warm_env.py: 2 pass (needs helm dependency build).
• helm unittest on charts/openhands: 184 pass, incl. the 2 new managed-proxy env tests; helm lint passes on both charts.

Note: the PR numbers "108" regression tests; the three suites total 76 + 31 + 2 = 109 here — a counting nit, not a coverage gap.

CI evidence

All 24 check runs on the head commit are green, including Test scripts, Helm Unit Tests, Check secret checksum, Validate Replicated Manifests, and pr.

Minor observations (non-blocking)

• charts/openhands/templates/troubleshoot/support-bundle.yaml's litellm-env-secrets presence-collector list was not extended with AZURE_AI_API_KEY/AZURE_AI_API_BASE. includeValue: false means no value exposure and secret content is still redacted, so this only affects presence reporting in support bundles. Worth a one-line addition.
• In both mode the default model always resolves to the Azure OpenAI route; switching to a Foundry default is a manual step. Reasonable given the "preserve existing default" goal, but worth noting in the field help.

The validation claims match the evidence: local renders, the test suites, the linter-backed checksum, and the external confirmation from @rajshah4 of release 1749 on a real Azure Replicated install corroborate the live-validation section of the PR body.

Follow-up verdict correction

After completing the full review I inspected the inline thread on charts/openhands/templates/_env.yaml (comment from aivong-openhands, marked Important) and confirmed it with a helm render:

helm template t charts/openhands --set enabled=true --set litellm-helm.enabled=false \
  --set litellm.url=https://proxy.example/v1 --set env.LITE_LLM_API_URL=https://override.example

results in OPENHANDS_PROVIDER_BASE_URL ($(LITE_LLM_API_URL)) appearing before the overridden LITE_LLM_API_URL in the container env list. Kubernetes only expands $(VAR) references to vars defined earlier, so a consumer that overrides env.LITE_LLM_API_URL (a supported, documented override under this chart's env contract) gets the literal string $(LITE_LLM_API_URL) as the provider base URL — every OpenHands-managed conversation fails silently. The Replicated installer path is unaffected (it never overrides LITE_LLM_API_URL), which is why the live-validation and the new tests pass, but the public chart path regresses against the codebase's override-friendly env requirements.

The fix is small and order-independent — compute the URL once and render it into both vars, e.g.:

{{- $liteLlmUrl := .Values.litellm.url }}
{{- if and (index .Values "litellm-helm") (index .Values "litellm-helm" "enabled") }}
{{- $liteLlmUrl = printf "http://%s-litellm.%s.svc.cluster.local:4000" .Release.Name .Release.Namespace }}
{{- end }}
- name: LITE_LLM_API_URL
  value: {{ $liteLlmUrl }}
- name: OPENHANDS_PROVIDER_BASE_URL
  value: {{ $liteLlmUrl }}

and update managed_llm_proxy_env_test.yaml to assert the concrete URL plus an override case (env.LITE_LLM_API_URL), so the regression is actually covered.

Everything else in my review stands (route coexistence, when gating, upgrade preservation, checksums, CI). On the strength of the unaddressed Important finding above, the verdict changes.

#1337 (review)

Summary: the Azure AI Foundry / drop-params config, checksum wiring, upgrade preservation, and route coexistence all verify locally (76 route tests, 31 checksum tests, 2 warm-env tests, 184 helm-unittest, helm lint; all 24 CI checks green). One unaddressed Important finding changes the verdict: OPENHANDS_PROVIDER_BASE_URL: $(LITE_LLM_API_URL) breaks when a consumer overrides env.LITE_LLM_API_URL — the env-var dedup moves the override below it, Kubernetes leaves $(LITE_LLM_API_URL) unexpanded, and managed conversations get a literal string as their provider URL. The new helm test asserts only the literal, so it cannot catch this. The Replicated path never overrides that var, which is why live validation passes. Recommend computing the URL once and rendering the same concrete value into both vars, plus a test that overrides env.LITE_LLM_API_URL.

Review posted to PR #1337

Reviewed the exact head commit f278d9370aa8087f7d4b6823c98e466a15950944 — verified the PR head is unchanged and matches the requested SHA. Review-only, no code pushed.

What I checked (and the evidence)

Correctness — all verified by rendering the KOTS templates locally:

• Azure / Foundry / both route coexistence with no name collisions and correct when gating
• Upgrade preservation: LITELLM_DEFAULT_MODEL and route names stay byte-identical for existing Azure OpenAI installs
• The API-version stability fix (rendering api_version directly instead of os.environ/…) matches the PR's route-deletion reproduction claim
• Checksum wiring: check_litellm_checksum.py (27 deps) and check_secret_checksum.py both pass

Regression coverage — all locally reproduced:

• 76 route tests, 31 checksum tests, 2 warm-env tests (after helm dependency build), 184 helm-unittest (incl. both new managed-proxy tests), helm lint clean on both charts
• All 24 GitHub check runs on the head commit are green, including Validate Replicated Manifests

The finding that changes the verdict

A pre-existing inline comment (flagged Important) on charts/openhands/templates/_env.yaml is a real, unaddressed bug that I confirmed with a helm render: OPENHANDS_PROVIDER_BASE_URL: $(LITE_LLM_API_URL) breaks when a consumer overrides env.LITE_LLM_API_URL — the chart's own env-var dedup moves the override below the provider URL, Kubernetes leaves $(LITE_LLM_API_URL) unexpanded, and managed conversations get a literal string as their provider URL. The PR's new helm test asserts only the literal string, so it can't catch it; the Replicated path never overrides that var, which is why live validation passes.

VERDICT: CHANGES_REQUESTED — with a concrete order-independent fix (compute the URL once, render into both vars) and a test that overrides env.LITE_LLM_API_URL.

Scope of this head commit

Follows up the prior review's Important finding on charts/openhands/templates/_env.yaml: OPENHANDS_PROVIDER_BASE_URL was $(LITE_LLM_API_URL), a literal reference that Kubernetes only expands if the target var appears earlier in the env list. Under this chart's env dedup contract, a consumer override env.LITE_LLM_API_URL is appended after this entry, so the managed-provider base URL silently degraded to the literal string. The commit computes the proxy URL once ($liteLlmUrl), emits it for LITE_LLM_API_URL, and renders the same value (or the env.LITE_LLM_API_URL override) directly into OPENHANDS_PROVIDER_BASE_URL — order-independent by construction. managed_llm_proxy_env_test.yaml now asserts the concrete URLs and adds an override case (env.LITE_LLM_API_URL), which fails on the previous head and passes here.

Verification (independent)

• scripts/test_replicated_llm_provider_routes.py: 76 passed, including test_azure_providers_coexist (4 param sets × 2 auth modes) and test_foundry_only_does_not_require_openai_fields.
• scripts/check_litellm_checksum.py: OK — 27 LiteLLM credential deps covered (matches the bumped EXPECTED_DEPENDENCY_COUNT = 27); scripts/check_secret_checksum.py: OK — 47 password fields.
• scripts/test_litellm_credentials_checksum.py + test_litellm_budget_cache.py: 32 passed.
• helm unittest charts/openhands (with subcharts off): 160 passed, including the 3 managed-proxy env tests; helm unittest charts/openhands-secrets: 12 passed.
• CI on the head is all green (helm-unittest, test-scripts, lint-and-test openhands/openhands-secrets, check-secret-checksum, scans).

Correctness checks in the earlier commits (unchanged, still sound)

• azure_provider_mode defaults to azure, so the azure-<deployment> route names and default model survive upgrades; Foundry routes azure_ai-<deployment>; the azure-ai- vs azure_ai- name-collision case is covered by the coexist test.
• when gating keeps OpenAI-only fields hidden in azure_ai mode and Foundry fields hidden in azure mode; stale stored values resolve empty.
• The rendered api_version (vs os.environ/AZURE_API_VERSION) keeps the route key stable across LiteLLM's startup overwrite; Foundry routes carry custom_llm_provider: azure_ai for Responses routing.
• azure_ai_api_key/azure_ai_endpoint are wired into litellm-env-secrets and covered by both checksums.

The warm-env tests could not be run here (they need chart deps not vendored in this checkout; the failure is a missing-dependency error before any Azure logic), but the test-scripts CI check on this head passed.

No findings at or above the important level. The prior Important finding is resolved and regression-covered.

Review complete. Summary of what I did:

Review posted to PR #1337

Substantive review: PR review 5532004461 — attached to the exact head commit c6cf50e66bd9dc52ed7d06881684dd888b332eda.

Verified:

1. Head commit unchanged — the PR head matches the requested SHA c6cf50e66bd9dc52ed7d06881684dd888b332eda both locally and via the GitHub API.
2. The head commit resolves the prior Important finding. It replaces OPENHANDS_PROVIDER_BASE_URL: $(LITE_LLM_API_URL) (which broke under env.LITE_LLM_API_URL overrides due to Kubernetes env-expansion ordering) with a URL computed once and rendered directly into both vars, with an added helm-unittest override case that fails on the prior head and passes here.
3. Independent test evidence (all run against the head commit):
   • 76 route tests pass (test_replicated_llm_provider_routes.py), including provider-coexistence and Foundry-only cases.
   • 27 LiteLLM credential deps covered by check_litellm_checksum.py; 47 password fields by check_secret_checksum.py; 32 credential/budget tests pass.
   • 160 helm unittest tests on the openhands chart (incl. the 3 managed-proxy env tests) + 12 on openhands-secrets all pass.
   • CI on the head is all green (helm-unittest, test-scripts, lint-and-test, check-secret-checksum, image scans).
   • The warm-env tests couldn't run in this sandbox (missing vendored chart deps), but that's provably environmental — the failure is a missing-dependency error before any Azure logic — and the CI test-scripts check passed.
4. Verdict: no findings at or above the important level → APPROVED. The prior Important finding is resolved with regression coverage.

One note: the token I have belongs to the PR author, so GitHub rejects an APPROVE review event on one's own PR ("Can not approve your own pull request"). I posted the identical substantive review as a COMMENT review (same as the previous reviews on this PR), with the REVIEWED_HEAD / REVIEW_REQUEST / VERDICT: APPROVED lines included as requested.
