Huawei Cloud Swr Image Governance

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.

Architecture: hcloud CLI → SWR Service API → Permission/Retention/Domain/Share/Agency resources

Related Skills:

• huawei-cloud-swr-image-management - Image lifecycle management (namespace, repo, tag, auth, quota)
• huawei-cloud-swr-image-automation - Image automation ops (sync, triggers, domains)
• huawei-cloud-swr-enterprise-instance - Enterprise instance management

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 version to verify installation
• First-time usage: printf "y\n" | hcloud version to 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_AK or echo $HUAWEI_CLOUD_SK to 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=
export HUAWEI_CLOUD_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

3. IAM Permission Requirements

See IAM Permission Policies for complete policy JSON.

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

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
hcloud SWR CreateUserRepositoryAuth --namespace=pancake --repository=openclaw-sandbox --1.auth=7 --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4

# Update repository permission for a user
hcloud SWR UpdateUserRepositoryAuth --namespace=pancake --repository=openclaw-sandbox --1.auth=3 --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4

# Revoke repository permission for a user
hcloud SWR DeleteUserRepositoryAuth --namespace=pancake --repository=openclaw-sandbox --1.user_id=05949eb5350010e21f85c017722182de --1.user_name=hwstaff_p00506267 --cli-region=cn-north-4

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
• CheckAgency returns whether agency is already configured; CreateAgency sets up the delegation

4. Retention Rules

See Task: Retention Management for detailed workflows.

# List retention rules for a repository
hcloud SWR ListRetentions --namespace=pancake --repository=openclaw-sandbox --cli-region=cn-north-4

# Create a retention rule (keep last 10 tags)
hcloud SWR CreateRetention --namespace=pancake --repository=openclaw-sandbox --algorithm=or --rules.1.template=tag_rule --rules.1.params.num=10 --rules.1.tag_selectors.1.kind=label --rules.1.tag_selectors.1.pattern=latest --cli-region=cn-north-4

# Create a retention rule (keep tags from last 30 days)
hcloud SWR CreateRetention --namespace=pancake --repository=openclaw-sandbox --algorithm=or --rules.1.template=date_rule --rules.1.params.days=30 --rules.1.tag_selectors.1.kind=label --rules.1.tag_selectors.1.pattern=latest --cli-region=cn-north-4

# Show retention rule details
hcloud SWR ShowRetention --namespace=pancake --repository=openclaw-sandbox --retention_id= --cli-region=cn-north-4

# Update a retention rule
hcloud SWR UpdateRetention --namespace=pancake --repository=openclaw-sandbox --retention_id= --algorithm=or --rules.1.template=tag_rule --rules.1.params.num=5 --rules.1.tag_selectors.1.kind=label --rules.1.tag_selectors.1.pattern=latest --cli-region=cn-north-4

# Delete a retention rule
hcloud SWR DeleteRetention --namespace=pancake --repository=openclaw-sandbox --retention_id= --cli-region=cn-north-4

# List retention execution histories
hcloud SWR ListRetentionHistories --namespace=pancake --repository=openclaw-sandbox --retention_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)

5. Shared Download Domains

See Task: Shared Domains for detailed workflows.

# List shared download domains for a repository
hcloud SWR ListRepoDomains --namespace=pancake --repository=openclaw-sandbox --cli-region=cn-north-4

# Create a shared download domain
hcloud SWR CreateRepoDomains --namespace=pancake --repository=openclaw-sandbox --domain=shared-domain-name --cli-region=cn-north-4

# Show shared domain details
hcloud SWR ShowAccessDomain --namespace=pancake --repository=openclaw-sandbox --access_domain=shared-domain-name --cli-region=cn-north-4

# Update a shared download domain
hcloud SWR UpdateRepoDomains --namespace=pancake --repository=openclaw-sandbox --domain=shared-domain-name --permit=read --cli-region=cn-north-4

# Delete a shared download domain
hcloud SWR DeleteRepoDomains --namespace=pancake --repository=openclaw-sandbox --access_domain=shared-domain-name --cli-region=cn-north-4

6. Image Sharing

See Task: Image Sharing for detailed workflows.

# List all shared repositories
hcloud SWR ListSharedReposDetails --cli-region=cn-north-4

# List shared repository details
hcloud SWR ListSharedRepoDetails --cli-region=cn-north-4

# Check sharing feature gates
hcloud SWR ShowShareFeatureGates --cli-region=cn-north-4

# Check global feature gates
hcloud SWR ListGlobalFeatureGates --cli-region=cn-north-4

7. Repository Accessories & References

# List repository accessories
hcloud SWR ListRepoAccessories --namespace=pancake --repository=openclaw-sandbox --cli-region=cn-north-4

# List repository references
hcloud SWR ListReferences --namespace=pancake --repository=openclaw-sandbox --cli-region=cn-north-4

Parameter Reference

Common Parameters

Permission Parameters

⚠️ Array Index Format: [N] starts from 1 (not 0). For granting permission to a single user, use --1.auth=7 --1.user_id=xxx --1.user_name=xxx. For multiple users, use --1.auth=7 --1.user_id=xxx --1.user_name=xxx --2.auth=3 --2.user_id=yyy --2.user_name=yyy.

Retention Parameters

Domain Parameters

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_auth vs others_auths: Check both when auditing permissions
• ListRepoDomains: Uses created/updated (NOT created_at/updated_at)
• ListRetentions: Returns flat array (empty [] when no rules)
• ListRepoAccessories: Uses total + accessories (null when empty)

Verification

See Verification Method for step-by-step verification.

Best Practices

1. Least Privilege: Grant the minimum auth level needed — 1 (read) for pull-only, 3 (edit) for push/pull, 7 (manage) for full control
2. Namespace vs Repository Permissions: Namespace permissions apply to ALL repositories under it; repository permissions are granular per-repo
3. Retention Rules: Use tag_rule (keep N most recent) for most cases; date_rule (keep tags within N days) for time-based cleanup
4. Retention Tag Selectors: Use label kind with latest pattern to protect important tags from retention cleanup
5. Shared Domains: Use deadline=forever for stable internal sharing; set specific deadlines for temporary cross-team access
6. Agency Delegation: Check agency status before configuring image sync or CCE triggers — these require agency to be enabled
7. Audit Permissions Regularly: Use ShowNamespaceAuth and ShowUserRepositoryAuth to periodically review who has access

Reference Documents

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 format
• ListRepoDomains timestamps use created/updated — NOT created_at/updated_at
