Huawei Cloud SWR Image Governance
Overview
This skill provides governance capabilities for Huawei Cloud SWR (Software Repository for Container) using the hcloud CLI, covering permissions, retention policies, sharing, and agency delegation.

Capabilities:
- Grant, query, modify, and revoke namespace-level permissions
- Grant, query, modify, and revoke repository-level permissions
- Create and manage image retention rules for automated cleanup
- Create and manage shared download domains for cross-organization access
- List shared repositories and check sharing feature gates
- Check and create agency delegation for SWR operations
- List repository accessories and references
Typical Use Cases:
- "Grant edit permission on namespace 'group-dev' to user 'dev-team'"
- "List all users with access to namespace 'group-dev'"
- "Set up a retention rule to keep only the last 10 tags in repository 'nginx'"
- "Create a shared download domain for repository 'my-app'"
- "List all shared repositories"
- "Check if image sharing feature is enabled"
- "Check agency delegation status for SWR"
- "Revoke a user's permission on a repository"
Prerequisites
1. hcloud CLI Requirements (MANDATORY)
- hcloud CLI installed (version >= 7.2.2)
- Run
hcloud versionto verify installation - First-time usage:
printf "y\n" | hcloud versionto accept privacy statement
2. Credential Configuration
- Valid Huawei Cloud credentials (AK/SK mode)
- Security Rules:
- 🚫 Never expose AK/SK values in code, conversation, or commands
- 🚫 Never use
echo $HUAWEI_CLOUD_AKorecho $HUAWEI_CLOUD_SKto check credentials - ✅ Use environment variables:
HUAWEI_CLOUD_AK,HUAWEI_CLOUD_SK,HUAWEI_CLOUD_REGION - ✅ Prefer IAM users over root account for cloud operations
- ✅ Enable MFA for sensitive operations
Configuration Method (Environment Variables Only):
export HUAWEI_CLOUD_AK=<your-ak>
export HUAWEI_CLOUD_SK=<your-sk>
export HUAWEI_CLOUD_REGION=cn-north-4
⚠️ Important Security Notes:
- Never commit credentials to version control
- Use IAM users with minimal required permissions
- Enable MFA for sensitive operations
- Rotate AK/SK regularly

See IAM Permission Policies for complete policy JSON.
Permission Failure Handling:
- When any command fails due to permission errors, read
references/iam-policies.md - Display the required permission list and policy JSON to the user
- Guide the user to create a custom policy in the IAM console and grant authorization
- Pause execution and wait for user confirmation that permissions have been granted
Core Commands
1. Namespace Permissions
See Task: Namespace Permissions for detailed workflows.
# Show namespace permissions (who has access and their auth levels)
hcloud SWR ShowNamespaceAuth --namespace=pancake --cli-region=cn-north-4
# Grant namespace permission to a user
hcloud SWR CreateNamespaceAuth --namespace=pancake --1.auth=7 --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4
# Update namespace permission for a user
hcloud SWR UpdateNamespaceAuth --namespace=pancake --1.auth=3 --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4
# Revoke namespace permission for a user
hcloud SWR DeleteNamespaceAuth --namespace=pancake --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4
Auth Values: 7 = manage (full control), 3 = edit (push/pull), 1 = read (pull only)
⚠️ Array-Style Parameters: Permission operations use --[N].auth, --[N].user_id, --[N].user_name format where [N] is the array index (starting from 1). For a single user, use --1.auth=7 --1.user_id=xxx --1.user_name=xxx. See Common Pitfalls for details.
2. Repository Permissions
See Task: Repository Permissions for detailed workflows.
# Show repository permissions
hcloud SWR ShowUserRepositoryAuth --namespace=pancake --repository=openclaw-sandbox --cli-region=cn-north-4
# Grant repository permission to a user

Auth Values: Same as namespace permissions: 7 = manage, 3 = edit, 1 = read
3. Agency Delegation
# Check if agency delegation is enabled
hcloud SWR CheckAgency --cli-region=cn-north-4
# Create agency delegation for SWR
hcloud SWR CreateAgency --cli-region=cn-north-4
Use Cases:
- Agency delegation allows SWR to access other services (OBS, CCE) on your behalf
- Required for features like image sync to OBS and CCE trigger deployments
CheckAgencyreturns whether agency is already configured;CreateAgencysets up the delegation

# Delete a retention rule
hcloud SWR DeleteRetention --namespace=pancake --repository=openclaw-sandbox --retention_id=<id> --cli-region=cn-north-4
# List retention execution histories
hcloud SWR ListRetentionHistories --namespace=pancake --repository=openclaw-sandbox --retention_id=<id> --cli-region=cn-north-4
Retention Rule Templates:
tag_rule: Keep a specified number of the most recent tags (params.num)date_rule: Keep tags created within a specified number of days (params.days)
Tag Selector Kinds:
label: Exact tag name match (e.g.,latest,v1.0)regexp: Regex pattern match (e.g.,v\d+\.\d+\.\d+)
Algorithm: or means rules are combined with OR logic (a tag is retained if it matches ANY rule)

Output Format
See Output Format for detailed response format examples (NamespaceAuth, RepositoryAuth, RepoDomains, CheckAgency, ShareFeatureGates, GlobalFeatureGates, Retentions, RepoAccessories, ListSharedReposDetails).
Key Format Notes:
auth: Permission value (7=manage, 3=edit, 1=read)self_authvsothers_auths: Check both when auditing permissionsListRepoDomains: Usescreated/updated(NOTcreated_at/updated_at)ListRetentions: Returns flat array (empty[]when no rules)ListRepoAccessories: Usestotal+accessories(null when empty)
Verification
See Verification Method for step-by-step verification.
Best Practices
- Least Privilege: Grant the minimum auth level needed —
1(read) for pull-only,3(edit) for push/pull,7(manage) for full control - Namespace vs Repository Permissions: Namespace permissions apply to ALL repositories under it; repository permissions are granular per-repo
- Retention Rules: Use
tag_rule(keep N most recent) for most cases;date_rule(keep tags within N days) for time-based cleanup - Retention Tag Selectors: Use
labelkind withlatestpattern to protect important tags from retention cleanup - Shared Domains: Use
deadline=foreverfor stable internal sharing; set specific deadlines for temporary cross-team access - Agency Delegation: Check agency status before configuring image sync or CCE triggers — these require agency to be enabled
- Audit Permissions Regularly: Use
ShowNamespaceAuthandShowUserRepositoryAuthto periodically review who has access

Notes
- Permission changes are immediate — no delay between granting and availability
- Revoke with caution — removing manage auth (7) prevents the user from administering the namespace/repository
- Retention rules execute automatically — tags matching the rule conditions will be deleted during execution
- 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 - ListRepoDomains timestamps use
created/updated— NOTcreated_at/updated_at
Common Pitfalls
See Common Pitfalls & Solutions for detailed troubleshooting guides.
Quick Reference:
| Pitfall | Symptom | Quick Fix |
|---|---|---|
| Array-style params | Permission grant fails | Use --1.auth=7 --1.user_id=xxx (index from 1, not 0) |
| Auth value wrong | User has unexpected access | 7=manage, 3=edit, 1=read (not 1/2/3) |
| self_auth vs others_auths | Missing user in audit | Check both self_auth and others_auths |
| Domain timestamp fields | Parsing created_at fails | Use created/updated (not created_at) |
| Retention rule format | CreateRetention fails | Nested array params: --rules.1.tag_selectors.1.kind |
| Agency not configured | Image sync/CCE trigger fails | Run CheckAgency then CreateAgency |
