This commit addresses the user feedback that configuration files should not
need to specify default paths when constants are available.
### Changes Made:
#### Configuration Simplification:
- Removed redundant basePath configurations from iam_config_distributed.json
- All stores now use constants for defaults:
* Sessions: /etc/iam/sessions (DefaultSessionBasePath)
* Policies: /etc/iam/policies (DefaultPolicyBasePath)
* Roles: /etc/iam/roles (DefaultRoleBasePath)
- Eliminated empty storeConfig objects entirely for cleaner JSON
#### Updated Store Implementations:
- FilerPolicyStore: Updated hardcoded path to use /etc/iam/policies
- FilerRoleStore: Updated hardcoded path to use /etc/iam/roles
- All stores consistently align with /etc/ filer convention
#### Runtime Filer Address Integration:
- Updated IAM manager methods to accept filerAddress parameter:
* AssumeRoleWithWebIdentity(ctx, filerAddress, request)
* AssumeRoleWithCredentials(ctx, filerAddress, request)
* IsActionAllowed(ctx, filerAddress, request)
* ExpireSessionForTesting(ctx, filerAddress, sessionToken)
- Enhanced S3IAMIntegration to store filerAddress from S3ApiServer
- Updated all test files to pass test filerAddress ('localhost:8888')
### Benefits:
- ✅ Cleaner, minimal configuration files
- ✅ Consistent use of well-defined constants for defaults
- ✅ No configuration needed for standard use cases
- ✅ Runtime filer address flexibility maintained
- ✅ Aligns with SeaweedFS /etc/ convention throughout
### Breaking Change:
- S3IAMIntegration constructor now requires filerAddress parameter
- All IAM manager methods now require filerAddress as second parameter
- Tests and middleware updated accordingly
This change addresses the requirement that filer addresses should be
passed when methods are called, not during initialization, to support:
- Dynamic filer failover and load balancing
- Runtime changes to filer topology
- Environment-agnostic configuration files
### Changes Made:
#### SessionStore Interface & Implementations:
- Updated SessionStore interface to accept filerAddress parameter in all methods
- Modified FilerSessionStore to remove filerAddress field from struct
- Updated MemorySessionStore to accept filerAddress (ignored) for interface consistency
- All methods now take: (ctx, filerAddress, sessionId, ...) parameters
#### STS Service Methods:
- Updated all public STS methods to accept filerAddress parameter:
- AssumeRoleWithWebIdentity(ctx, filerAddress, request)
- AssumeRoleWithCredentials(ctx, filerAddress, request)
- ValidateSessionToken(ctx, filerAddress, sessionToken)
- RevokeSession(ctx, filerAddress, sessionToken)
- ExpireSessionForTesting(ctx, filerAddress, sessionToken)
#### Configuration Cleanup:
- Removed filerAddress from all configuration files (iam_config_distributed.json)
- Configuration now only contains basePath and other store-specific settings
- Makes configs environment-agnostic (dev/staging/prod compatible)
#### Test Updates:
- Updated all test files to pass testFilerAddress parameter
- Tests use dummy filerAddress ('localhost:8888') for consistency
- Maintains test functionality while validating new interface
### Benefits:
- ✅ Filer addresses determined at runtime by caller (S3 API server)
- ✅ Supports filer failover without service restart
- ✅ Configuration files work across environments
- ✅ Follows SeaweedFS patterns used elsewhere in codebase
- ✅ Load balancer friendly - no filer affinity required
- ✅ Horizontal scaling compatible
### Breaking Change:
This is a breaking change for any code calling STS service methods.
Callers must now pass filerAddress as the second parameter.
- Update DefaultSessionBasePath to /etc/iam/sessions (was /seaweedfs/iam/sessions)
- Update DefaultPolicyBasePath to /etc/iam/policies (was /seaweedfs/iam/policies)
- Update DefaultRoleBasePath to /etc/iam/roles (was /seaweedfs/iam/roles)
- Update iam_config_distributed.json to use /etc/iam paths
- Align with existing filer configuration structure in filer_conf.go
- Follow SeaweedFS convention of storing configs under /etc/
- Add FILER_INTEGRATION.md documenting path conventions
- Maintain consistency with IamConfigDirectory = '/etc/iam'
- Enable standard filer backup/restore procedures for IAM data
- Ensure operational consistency across SeaweedFS components
PROBLEM SOLVED:
- Roles were stored in memory per-instance, causing inconsistencies
- Sessions and policies had filer storage but roles didn't
- Multi-instance deployments had authentication failures
IMPLEMENTATION:
- Add RoleStore interface for pluggable role storage backends
- Implement FilerRoleStore using SeaweedFS filer as distributed backend
- Update IAMManager to use RoleStore instead of in-memory map
- Add role store configuration to IAM config schema
- Support both memory and filer storage for roles
NEW COMPONENTS:
- weed/iam/integration/role_store.go - Role storage interface & implementations
- weed/iam/integration/role_store_test.go - Unit tests for role storage
- test/s3/iam/iam_config_distributed.json - Sample distributed config
- test/s3/iam/DISTRIBUTED.md - Complete deployment guide
CONFIGURATION:
{
'roleStore': {
'storeType': 'filer',
'storeConfig': {
'filerAddress': 'localhost:8888',
'basePath': '/seaweedfs/iam/roles'
}
}
}
BENEFITS:
- ✅ Consistent role definitions across all S3 gateway instances
- ✅ Persistent role storage survives instance restarts
- ✅ Scales to unlimited number of gateway instances
- ✅ No session affinity required in load balancers
- ✅ Production-ready distributed IAM system
This completes the distributed IAM implementation, making SeaweedFS
S3 Gateway truly scalable for production multi-instance deployments.
