Add MPSS model-publisher self-serve commands to ml extension by sanskritityagi · Pull Request #9956 · Azure/azure-cli-extensions

sanskritityagi · 2026-06-18T15:57:06Z

Layer the az ml modelpublisher command group (gpu-config, plan, model, release-candidate, model-card, registry) onto the ml extension. Adds the custom module model_hosting.py plus MPSS helpers in utils.py.

The command group is registered as a normal preview surface (is_preview=True) — available without setting any private-feature env var — so publishers get it with no extra setup. It does not flip the global AZURE_ML_CLI_PRIVATE_FEATURES_ENABLED flag, so existing private/preview features (e.g. virtualcluster) remain gated and unchanged for current users.

This lets publishers use the latest ml commands (e.g. deployment-template) and the modelpublisher commands from a single extension instead of swapping between two.

This checklist is used to make sure that common guidelines for a pull request are followed.

Layer the 'az ml modelpublisher' command group (gpu-config, plan, model, release-candidate, model-card, registry) onto ml v2.43.0. New custom module model_hosting.py + MPSS helpers in utils.py; gated behind private features.

- Bump ml extension to 2.44.0 + HISTORY.rst entry for modelpublisher commands - Use custom_show_command for modelpublisher show commands - Add missing command/parameter help (model-card-internal, plan update --status) - Drop multi-character short options flagged by linter - Fix flake8 (f-strings, blank lines, None comparison, unused vars, import order) - Satisfy pylint (unused-argument, broad-except, no-else-return, useless-return)

- make_request now raises BadRequest/Forbidden/ResourceNotFound on 4xx instead of logging and returning None (commands no longer silently 'succeed') - Pass --location through to get_self_serve_base_url in gpu-config and plan handlers so requests route to the intended environment - model-card attach: send JSON body instead of a dict (correct content-type) - Guard download when no filename can be determined (clear error vs TypeError) - run_registry_mgmt_cmd: check=True and surface failures as a CLI error - Gate modelpublisher help behind private_features_enabled (consistent gating) - Use a placeholder tenantId in the sample - Fix typos (deprecated, existing)

- Remove the unconditional AZURE_ML_CLI_PRIVATE_FEATURES_ENABLED=True from azext_mlv2/__init__.py (it enabled ALL private/preview features for every user) - Register 'az ml modelpublisher' as a normal preview command group (un-gate it in commands.py, _params, and _help) so publishers get it without setting an env var, while virtualcluster / private job & component features stay gated - Guard validate_config_file against empty/non-mapping YAML (clear error vs TypeError)

- make_request now treats any 2xx (201/202/204) as success and handles empty bodies, instead of only 200 (other success codes were raised as errors) - Download streams to disk via iter_content instead of buffering the full body - Fix help text grammar ('for a given publisher') and wording ('Microsoft PMs')

… dep - Add a network timeout to all MPSS and model-card-template HTTP calls so a hung connection can't block the CLI - Sanitize downloaded filename to a basename (prevent path traversal from a server-supplied content-disposition header) - generate-template now raises on download failure instead of exiting success - _load_self_serve_config raises FileOperationError (CLI-friendly) not Exception - Pin azureml-registry-tools==0.1.0a58

- Read self-serve config with explicit UTF-8 encoding (portability on non-UTF-8 locales) - run_registry_mgmt_cmd raises CLIInternalError (clean message) instead of passing a string to log_and_raise_error - make_request drops unset (None) query params so pagination isn't sent as currentPage=None - Chain the original exception (from e) when re-raising in model-card update - Fix help text spacing ('model .' -> 'model.')

…rrors - _download_file_from_response accepts any 2xx (consistent with make_request) - run_registry_mgmt_cmd raises an actionable error if 'registry-mgmt' is not installed/on PATH - model-card apply fails with InvalidArgumentValueError on a malformed --model-id (and a clear error if registry info can't be resolved) instead of silently succeeding - _load_self_serve_config converts JSON parse errors into FileOperationError

- plan show builds a clean base URL and passes offerId/planId via params (avoids fragile ternary URL concatenation / encoding issues) - get_registry_info fails with a clear error if subscription/resource group can't be resolved for the registry (instead of '--subscription None') - load_inline_md_files opens with UTF-8 and validates the YAML is a mapping
