Huawei Cloud ModelArts Notebook Management
Full lifecycle management for ModelArts Notebook instances via hcloud CLI — 31 API interfaces across 7 functional domains.
Overview
This skill enables users to manage Huawei Cloud ModelArts Notebook instances through the hcloud CLI. It covers the complete notebook lifecycle including instance CRUD, start/stop, lease renewal, tag management, image management, flavor/cluster queries, feature queries, and dynamic storage management.
Architecture
User Request → Agent → hcloud ModelArts <Operation> --cli-region={region} [--params] → Huawei Cloud ModelArts API
Applicable Scenarios
- Daily Operations: List notebooks, check status, view details, query flavors
- Instance Lifecycle: Create, start, stop, update, delete notebook instances
- Image Management: Save running instance as image, register/list/delete/sync custom images
- Storage Management: Dynamically attach/detach storage to notebook instances
- Lease Management: Query and renew notebook leases
- Tag Management: Create, delete, query notebook tags
Scope
本 skill 仅支持 ModelArts Notebook 实例管理(31 个 API),涵盖上述 7 个功能域。
不支持以下 ModelArts 能力,相关请求请使用对应 skill:
- 推理服务(在线服务、批量服务)— 使用推理服务管理 skill
- DevServer(开发环境)— 使用 DevServer 管理 skill
- 模型管理(导入/导出/发布模型)— 使用模型管理 skill
- 训练作业(创建/管理训练任务)— 使用训练作业管理 skill
- 自动搜索、超参调优 — 使用自动搜索 skill
Prerequisites
- hcloud CLI installed and authenticated — Reference: https://support.huaweicloud.com/qs-hcli/hcli_02_003.html
- Huawei Cloud AK/SK configured via hcloud (see Security & Credential Check below)
- ModelArts service enabled in the target region
- IAM permissions — See references/iam-policies.md
Security & Credential Check
⚠️ CRITICAL: This section defines the agent's security boundary. Follow it strictly.
🔒 Security Rules (MANDATORY)
- 🚫 NEVER read, echo, or print AK/SK values (e.g.,
cat ~/.hcloud/config.json, echo $HW_ACCESS_KEY is FORBIDDEN)
- 🚫 NEVER read or cat credential files such as
~/.hcloud/config.json or any file that may contain secrets
- 🚫 NEVER ask the user to input AK/SK directly in the conversation or command line
- 🚫 NEVER execute
hcloud configure set --cli-access-key=... --cli-secret-key=... — credential configuration is the user's responsibility, done outside the agent session
- 🚫 NEVER pass
--cli-access-key/--cli-secret-key on every API call — they will be exposed in process listings (ps aux) for the entire request duration
- ✅ ALWAYS use
hcloud configure list to check credential status (presence check only, not values)
- ✅ If no valid profile exists, STOP and instruct the user to configure credentials outside this session
- ✅ Recommend using IAM user with minimal permissions instead of main account
✅ Agent Credential Check (the ONLY acceptable check)
# Step 1: Check credential status — presence only, not values
hcloud configure list
✅ Expected: Shows a valid profile with mode: AKSK
❌ If empty/invalid → Guide the user with the 3-step process below:
Step-by-step guidance (copy-paste for the user):
"No valid credentials found. Please follow these 3 steps in your terminal:"
① Get your AK/SK
Log in to Huawei Cloud Console → IAM → Access Keys. If you don't have one, click "Create Access Key" and save it securely.
② Run this in your terminal (one-time setup):
hcloud configure set --cli-access-key=<YOUR_AK> --cli-secret-key=<YOUR_SK>
(Replace <YOUR_AK> and <YOUR_SK> with the values from step ①)
③ Come back and tell me "configured", I'll verify it works.
Note: The configure set command stores your credentials in ~/.hcloud/config.json. After that, all hcloud commands use them automatically — no need to pass AK/SK again.
Agent: DO NOT execute any configure set command yourself.
🔧 User's Responsibility (for documentation, NOT agent execution)
The user configures credentials outside the agent session (in their own terminal):
# One-time setup — run this in your terminal, NOT in the agent chat
HISTCONTROL=ignorespace
hcloud configure set --cli-access-key=<YOUR_AK> --cli-secret-key=<YOUR_SK>
⚠️ Note: hcloud CLI does NOT read HW_ACCESS_KEY/HW_SECRET_KEY environment variables (those are for Python SDK only). hcloud configure set is the only supported credential configuration method.
Workflow
Step 1: Identify the Operation
Determine which notebook operation the user needs based on their request:
| User Intent |
Operation Category |
| Create/list/view/update/delete/start/stop notebook |
Instance Management |
| Query/renew lease |
Lease Management |
| Create/delete/query tags |
Tag Management |
| Save/register/list/delete/sync image |
Image Management |
| Query flavors/clusters/features |
Flavor & Cluster |
| Attach/detach/list storage |
Dynamic Storage |
Step 2: Execute CLI Command
hcloud ModelArts <Operation> --cli-region={region} [--key=value ...]
{region} must be replaced with the actual region, e.g., cn-north-4. Do NOT hardcode the region.
Step 2.5: Consult Known Issues (Write Operations Only)
Before executing any write operation, read references/known-issues.md and check for known pitfalls, parameter corrections, and required workarounds for the target API.
Common workarounds to apply:
| API |
Issue |
Workaround |
| CreateNotebook (EVS) |
CLI rejects --volume.category=EVS |
Use --cli-jsonInput with {"body":{...}} wrapper + explicit --project_id |
| CreateNotebook |
Param name flavor_id wrong |
Use --flavor |
| CreateNotebook |
Param name volume.size wrong |
Use --volume.capacity |
| CreateNotebook |
ownership=PRIVATE invalid |
Use MANAGED or DEDICATED |
| AttachDynamicStorage |
STOPPED instance rejected |
Ensure instance is RUNNING |
| AttachDynamicStorage |
mount_path format |
Must start with /data/ and end with / |
| RegisterImage |
arch case mismatch |
Use uppercase X86_64/AARCH64 |
| RenewLease |
type case mismatch |
Use lowercase timing/idle |
This step is mandatory for all write operations. Skipping it may result in CLI parameter errors or API failures that are already documented.
Step 3: Handle Write Operations
For all write operations (Create/Update/Delete/Start/Stop/Attach/Detach/Register/Sync/Renew), prompt the user for confirmation before execution. For chargeable operations (CreateNotebook, StartNotebook), inquire BSS pricing first to inform the user of costs. See references/pricing-inquiry.md for the pricing inquiry workflow.
删除类操作交互指引:当用户请求删除标签(DeleteNotebookTags)、删除镜像分组(DeleteImageGroup)等操作但未指定具体对象时,必须先查询当前对象列表(如 ShowNotebookTags / ListImageGroup),向用户展示并确认要删除哪个对象,确认后再执行。避免因上下文不明确导致误删。

| # |
Issue |
Key Takeaway |
| 1 |
CLI omits EVS from volume.category enum |
Use --cli-jsonInput with body wrapper + explicit --project_id |
| 2 |
Storage category × ownership matrix |
EVS:MANAGED ✅, OBS/OBSFS:DEDICATED ✅, OBS/OBSFS:MANAGED ❌ |
| 3 |
DEDICATED ownership requires pool_id |
Query dedicated pools first, pass top-level pool_id |
| 4 |
OBS as data_volume silently fails |
Use OBS as main volume or use OBSFS as data_volume |
| 5 |
Bucket type (POSIX vs OBJECT) irrelevant |
Both work with DEDICATED ownership |
| 6 |
OBSFS:MANAGED extended storage unsupported |
Use DEDICATED for OBSFS |
| 7 |
OBS/OBSFS main volume needs dew_secret_name |
Store AK/SK in DEW/CSMS secret |
| 8 |
OBS data volume requires mount_path |
Always specify valid path |
| 9 |
Image/flavor architecture mismatch |
Match arch field between image and flavor |
| 10 |
--cli-jsonInput general workaround |
Must wrap in {"body":{...}} + pass --project_id explicitly |
| 11 |
ShowLease duration is total, not remaining |
Calculate: remaining = (create_at + duration) - current_time |
| 12 |
ListImageGroup response field varies with --limit |
Without limit: groups field; with limit: data field. Parse both |
| 13 |
AttachDynamicStorage only supports POSIX buckets |
OBJECT buckets rejected with ModelArts.6772; use obsutil stat to verify |
Notes
- All 31 API interfaces are available via
hcloud ModelArts CLI
- SDK fallback available via
huaweicloudsdkmodelarts v1 if CLI encounters issues
- Region is specified via
--cli-region and should NOT be hardcoded
--project_id is auto-resolved from credentials if omitted (but must be explicit when using --cli-jsonInput)
- All write operations (Create/Update/Delete/Start/Stop/Attach/Detach/Register/Sync/Renew) require user confirmation before execution
- Chargeable operations (CreateNotebook, StartNotebook) require BSS pricing inquiry to inform users of costs before execution
- API paths verified from SDK source
_http_info resource_path — no inferred endpoints
- No hardcoded AK/SK in any file — credentials managed by hcloud via
hcloud configure list/set

254| 1 | CLI omits EVS from `volume.category` enum | Use `--cli-jsonInput` with `body` wrapper + explicit `--project_id` |
255| 2 | Storage category × ownership matrix | EVS:MANAGED ✅, OBS/OBSFS:DEDICATED ✅, OBS/OBSFS:MANAGED ❌ |
256| 3 | DEDICATED ownership requires `pool_id` | Query dedicated pools first, pass top-level `pool_id` |
257| 4 | OBS as `data_volume` silently fails | Use OBS as main `volume` or use OBSFS as `data_volume` |
258| 5 | Bucket type (POSIX vs OBJECT) irrelevant | Both work with DEDICATED ownership |
259| 6 | OBSFS:MANAGED extended storage unsupported | Use DEDICATED for OBSFS |
260| 7 | OBS/OBSFS main volume needs `dew_secret_name` | Store AK/SK in DEW/CSMS secret |
261| 8 | OBS data volume requires `mount_path` | Always specify valid path |
262| 9 | Image/flavor architecture mismatch | Match `arch` field between image and flavor |
263| 10 | `--cli-jsonInput` general workaround | Must wrap in `{"body":{...}}` + pass `--project_id` explicitly |
264| 11 | `ShowLease` duration is total, not remaining | Calculate: `remaining = (create_at + duration) - current_time` |
265| 12 | `ListImageGroup` response field varies with `--limit` | Without limit: `groups` field; with limit: `data` field. Parse both |
266| 13 | `AttachDynamicStorage` only supports POSIX buckets | OBJECT buckets rejected with `ModelArts.6772`; use `obsutil stat` to verify |

270## Notes
271
272- All 31 API interfaces are available via `hcloud ModelArts` CLI
273- SDK fallback available via `huaweicloudsdkmodelarts` v1 if CLI encounters issues
274- Region is specified via `--cli-region` and should NOT be hardcoded
275- `--project_id` is auto-resolved from credentials if omitted (but **must be explicit** when using `--cli-jsonInput`)
276- All write operations (Create/Update/Delete/Start/Stop/Attach/Detach/Register/Sync/Renew) require user confirmation before execution
277- Chargeable operations (CreateNotebook, StartNotebook) require BSS pricing inquiry to inform users of costs before execution
278- API paths verified from SDK source `_http_info` `resource_path` — no inferred endpoints
279- No hardcoded AK/SK in any file — credentials managed by hcloud via `hcloud configure list/set`
