Huawei Cloud SWR enterprise instance management skill using hcloud CLI.

Use this skill when the user wants to: (1) manage SWR enterprise instances - create/list/show/delete/update configuration, (2) manage instance namespaces - create/list/show/update/delete with security scanning settings, (3) manage instance registries (sync targets) - create/list/show/update/delete, (4) manage instance repositories - list/show/delete/update, (5) manage instance artifacts (image versions) - list/show/delete/scan, (6) manage instance credentials - long-term and temporary, (7) manage instance endpoints - internal/public access, (8) manage instance domains - add/list/show/delete/update, (9) check instance statistics and job status.

Trigger: user mentions "SWR enterprise instance", "SWR 企业实例", "SWR 企业版", "企业仓库实例", "SWR instance", "SWR 专业版", "swr.ee", "instance namespace", "instance registry", "instance repository", "instance artifact", "instance credential", "instance endpoint", "instance domain", "企业仓库", "实例管理"

# Huawei Cloud SWR Enterprise Instance Management

## Overview

This skill provides lifecycle management capabilities for Huawei Cloud SWR (Software Repository for Container) enterprise instances using the `hcloud` CLI. Enterprise instances provide dedicated, isolated container registry environments with advanced features like security scanning, replication policies, and custom domain support.

**Architecture**: hcloud CLI → SWR Service API → Instance/Namespace/Registry/Repository/Artifact/Credential/Endpoint/Domain resources

**Related Skills**:

- `huawei-cloud-swr-image-management` - Image lifecycle management (basic SWR namespaces, repos, tags, auth, quotas)

- `huawei-cloud-swr-image-governance` - Image governance (permissions, retention, sharing, tags, immutable rules)

- `huawei-cloud-swr-image-automation` - Image automation ops (sync, triggers, domains)

- Create and manage SWR enterprise instances

- Manage instance namespaces with security scanning and vulnerability blocking

- Configure instance registries for cross-instance image sync

- Query and manage instance repositories and artifacts

- Obtain instance access credentials (long-term and temporary)

- Configure instance network access (internal VPC endpoints, public access with whitelist)

- Manage custom domains for instance access

- Monitor instance statistics and job status

**Typical Use Cases**:

- "Create an SWR enterprise instance for my organization"

- "List all enterprise instances in my project"

- "Create a namespace with auto-scan and vulnerability blocking"

- "Configure a registry for syncing images to another instance"

- "List repositories and artifacts in my instance"

- "Get docker login credentials for my instance"

- "Add a VPC internal endpoint for my instance"

- "Enable public access with IP whitelist"

- "Add a custom domain to my instance"

- "Check instance statistics and resource usage"

## Prerequisites

### 1. hcloud CLI Requirements (MANDATORY)

- hcloud CLI installed (version >= 7.2.2)

- Run `hcloud version` to verify installation

- First-time usage: `printf "y\n" | hcloud version` to accept privacy statement

### 2. Credential Configuration

hcloud CLI supports two credential modes. See [references/credential-configuration.md](references/credential-configuration.md) for full details.

**Quick setup** (choose one):

```bash

# Mode A — Long-term AK/SK

export HUAWEI_CLOUD_AK=<your-ak>

export HUAWEI_CLOUD_SK=<your-sk>

export HUAWEI_CLOUD_REGION=cn-north-4

# Mode B — Temporary AK/SK + SecurityToken

export HUAWEI_CLOUD_AK=<your-temp-ak>

export HUAWEI_CLOUD_SK=<your-temp-sk>

export HUAWEI_CLOUD_SECURITY_TOKEN=<your-security-token>

export HUAWEI_CLOUD_REGION=cn-north-4

```

- **Security rules**: Never expose AK/SK/SecurityToken values. Use `hcloud configure list` to check presence only.

**Permission Failure Handling**:

1. When any command fails due to permission errors, read `references/iam-policies.md`

2. Display the required permission list and policy JSON to the user

3. Guide the user to create a custom policy in the IAM console and grant authorization

4. Pause execution and wait for user confirmation that permissions have been granted

## Output Format

See [Output Format](references/output-format.md) for detailed response format examples (Instance List, Instance Details, Namespace List, Internal Endpoint List, Domain Name List, Long-term Credential).

## Verification

See [Verification Method](references/verification-method.md) for step-by-step verification.

## Best Practices

1. **Instance naming**: Use descriptive names like `prod-instance`, `dev-instance` that reflect the environment

2. **VPC selection**: Choose VPC/subnet that matches your workload deployment environment

3. **Namespace security**: Enable `auto_scan=true` and `prevent_vul=true` for production namespaces to block vulnerable images

4. **Severity blocking**: Set `severity=high` or `critical` for production; use `none` or `low` for development

5. **Registry credentials**: Store registry credentials securely; rotate access keys periodically

6. **Public access whitelist**: Always configure IP whitelist when enabling public access; use `UpdateInstanceEndpointPolicy` for full whitelist management

## Notes

- **Instance deletion is irreversible** — removes ALL namespaces, repositories, artifacts, and data permanently

- **Namespace deletion is irreversible** — removes all repositories and artifacts under it

- **Artifact deletion is irreversible** — the image version cannot be recovered

- **Default domain cannot be deleted** — only custom domains can be removed

- **AK/SK must never be hardcoded** — credentials should only be obtained via environment variables

- **hcloud CLI is the only supported method** — all operations use `hcloud SWR <Operation>` format

- **Pagination offset must be multiple of limit** — `offset` must be 0 or a multiple of `limit`

- **Registry credential.access_secret is sensitive** — never expose or log access secrets

## Common Pitfalls

See [Common Pitfalls & Solutions](references/common-pitfalls.md) for detailed troubleshooting guides.

**Quick Reference**:

| Pitfall | Symptom | Quick Fix |

| ------------------------------- | ------------------------------- | -------------------------------------------- |

| Invalid instance name | 400 Bad Request | 3-48 chars, lowercase start, no consecutive hyphens |

| VPC/subnet not found | Instance creation fails | Verify VPC/subnet exist in region |

| Instance still creating | Operations fail | Wait for Running, check with ListInstance |

| Offset not multiple of limit | Pagination returns error | offset must be 0 or multiple of limit |

| Registry credential wrong | Sync fails | Verify access_key/access_secret |

| Domain cert not found | Domain creation fails | Verify certificate_id in SCM |

| Cannot delete default domain | Delete fails | Only custom domains can be deleted |

| Public access whitelist format | Whitelist update fails | Use indexed: --ip_list.1.ip=value |
