feat: Implement distributed IAM role storage for multi-instance deployments
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.

# Distributed IAM for SeaweedFS S3 Gateway
|
||||
|
||||
This document explains how to configure SeaweedFS S3 Gateway for distributed environments with multiple gateway instances.
|
||||
|
||||
## Problem Statement
|
||||
|
||||
In distributed environments with multiple S3 gateway instances, the default in-memory storage for IAM components causes **serious consistency issues**:
|
||||
|
||||
- **Roles**: Each instance maintains separate in-memory role definitions
|
||||
- **Sessions**: STS sessions created on one instance aren't visible on others
|
||||
- **Policies**: Policy updates don't propagate across instances
|
||||
- **Authentication failures**: Users may get different responses from different instances
|
||||
|
||||
## Solution: Filer-Based Distributed Storage
|
||||
|
||||
SeaweedFS now supports **distributed IAM storage** using the filer as a centralized backend for:
|
||||
|
||||
- ✅ **Role definitions** (FilerRoleStore)
|
||||
- ✅ **STS sessions** (FilerSessionStore)
|
||||
- ✅ **IAM policies** (FilerPolicyStore)
|
||||
|
||||
All S3 gateway instances share the same IAM state through the filer.
|
||||
|
||||
## Configuration
|
||||
|
||||
### Standard Configuration (Single Instance)
|
||||
```json
|
||||
{
|
||||
"sts": {
|
||||
"tokenDuration": 3600000000000,
|
||||
"maxSessionLength": 43200000000000,
|
||||
"issuer": "seaweedfs-sts",
|
||||
"signingKey": "base64-encoded-signing-key"
|
||||
},
|
||||
"policy": {
|
||||
"defaultEffect": "Deny",
|
||||
"storeType": "memory"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Distributed Configuration (Multiple Instances)
|
||||
```json
|
||||
{
|
||||
"sts": {
|
||||
"tokenDuration": 3600000000000,
|
||||
"maxSessionLength": 43200000000000,
|
||||
"issuer": "seaweedfs-sts",
|
||||
"signingKey": "base64-encoded-signing-key",
|
||||
"sessionStoreType": "filer",
|
||||
"sessionStoreConfig": {
|
||||
"filerAddress": "localhost:8888",
|
||||
"basePath": "/seaweedfs/iam/sessions"
|
||||
}
|
||||
},
|
||||
"policy": {
|
||||
"defaultEffect": "Deny",
|
||||
"storeType": "filer",
|
||||
"storeConfig": {
|
||||
"filerAddress": "localhost:8888",
|
||||
"basePath": "/seaweedfs/iam/policies"
|
||||
}
|
||||
},
|
||||
"roleStore": {
|
||||
"storeType": "filer",
|
||||
"storeConfig": {
|
||||
"filerAddress": "localhost:8888",
|
||||
"basePath": "/seaweedfs/iam/roles"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Storage Backends
|
||||
|
||||
### Memory Storage (Default)
|
||||
- **Performance**: Fastest access (sub-millisecond)
|
||||
- **Persistence**: Lost on restart
|
||||
- **Distribution**: ❌ Not shared across instances
|
||||
- **Use case**: Single instance or development
|
||||
|
||||
### Filer Storage (Distributed)
|
||||
- **Performance**: Network latency + filer performance
|
||||
- **Persistence**: ✅ Survives restarts
|
||||
- **Distribution**: ✅ Shared across all instances
|
||||
- **Use case**: Production multi-instance deployments
|
||||
|
||||
## Deployment Examples
|
||||
|
||||
### Single Instance (Simple)
|
||||
```bash
|
||||
# Standard deployment - no special configuration needed
|
||||
weed s3 -filer=localhost:8888 -port=8333
|
||||
```
|
||||
|
||||
### Multiple Instances (Distributed)
|
||||
```bash
|
||||
# Instance 1
|
||||
weed s3 -filer=localhost:8888 -port=8333 -iam.config=/path/to/distributed_config.json
|
||||
|
||||
# Instance 2
|
||||
weed s3 -filer=localhost:8888 -port=8334 -iam.config=/path/to/distributed_config.json
|
||||
|
||||
# Instance N
|
||||
weed s3 -filer=localhost:8888 -port=833N -iam.config=/path/to/distributed_config.json
|
||||
```
|
||||
|
||||
All instances share the same IAM state through the filer.
|
||||
|
||||
### Load Balancer Configuration
|
||||
```nginx
|
||||
upstream seaweedfs-s3 {
|
||||
# No need for session affinity with distributed storage
|
||||
server gateway-1:8333;
|
||||
server gateway-2:8334;
|
||||
server gateway-3:8335;
|
||||
}
|
||||
|
||||
server {
|
||||
listen 80;
|
||||
location / {
|
||||
proxy_pass http://seaweedfs-s3;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Storage Locations
|
||||
|
||||
When using filer storage, IAM data is stored at:
|
||||
|
||||
```
|
||||
/seaweedfs/iam/
|
||||
├── sessions/ # STS session tokens
|
||||
│ ├── session_abc123.json
|
||||
│ └── session_def456.json
|
||||
├── policies/ # IAM policy documents
|
||||
│ ├── policy_S3AdminPolicy.json
|
||||
│ └── policy_S3ReadOnlyPolicy.json
|
||||
└── roles/ # IAM role definitions
|
||||
├── S3AdminRole.json
|
||||
└── S3ReadOnlyRole.json
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Memory vs Filer Storage
|
||||
|
||||
| Aspect | Memory | Filer |
|
||||
|--------|--------|-------|
|
||||
| **Read Latency** | <1ms | ~5-20ms |
|
||||
| **Write Latency** | <1ms | ~10-50ms |
|
||||
| **Consistency** | Per-instance | Global |
|
||||
| **Persistence** | None | Full |
|
||||
| **Scalability** | Limited | Unlimited |
|
||||
|
||||
### Optimization Tips
|
||||
|
||||
1. **Use fast storage** for the filer (SSD recommended)
|
||||
2. **Co-locate filer** with S3 gateways to reduce network latency
|
||||
3. **Enable filer caching** for frequently accessed IAM data
|
||||
4. **Monitor filer performance** - IAM operations depend on it
|
||||
|
||||
## Migration Guide
|
||||
|
||||
### From Single to Multi-Instance
|
||||
|
||||
1. **Stop existing S3 gateway**
|
||||
2. **Update configuration** to use filer storage:
|
||||
```json
|
||||
{
|
||||
"policy": { "storeType": "filer" },
|
||||
"sts": { "sessionStoreType": "filer" },
|
||||
"roleStore": { "storeType": "filer" }
|
||||
}
|
||||
```
|
||||
3. **Start first instance** with new config
|
||||
4. **Verify IAM data** was migrated to filer
|
||||
5. **Start additional instances** with same config
|
||||
|
||||
### From Memory to Filer Storage
|
||||
|
||||
IAM data in memory is **not automatically migrated**. You'll need to:
|
||||
|
||||
1. **Export existing roles/policies** from configuration files
|
||||
2. **Update configuration** to use filer storage
|
||||
3. **Restart with new config** - data will be loaded from config into filer
|
||||
4. **Remove config-based definitions** (now stored in filer)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Configuration Issues
|
||||
```bash
|
||||
# Check IAM configuration is loaded correctly
|
||||
grep "advanced IAM" /path/to/s3-gateway.log
|
||||
|
||||
# Verify filer connectivity
|
||||
weed filer.cat /seaweedfs/iam/roles/
|
||||
```
|
||||
|
||||
### Inconsistent Behavior
|
||||
```bash
|
||||
# Check if all instances use same filer
|
||||
curl http://gateway-1:8333/status
|
||||
curl http://gateway-2:8334/status
|
||||
|
||||
# Verify IAM storage locations exist
|
||||
weed filer.ls /seaweedfs/iam/
|
||||
```
|
||||
|
||||
### Performance Issues
|
||||
```bash
|
||||
# Monitor filer latency
|
||||
curl http://filer:8888/stats
|
||||
|
||||
# Check IAM storage path performance
|
||||
time weed filer.cat /seaweedfs/iam/roles/TestRole.json
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Security
|
||||
- **Secure filer access** - use TLS and authentication
|
||||
- **Limit IAM path access** - only S3 gateways should access `/seaweedfs/iam/`
|
||||
- **Regular backups** of IAM data in filer
|
||||
- **Monitor access** to IAM storage paths
|
||||
|
||||
### High Availability
|
||||
- **Replicate filer** across multiple nodes
|
||||
- **Use fast, reliable storage** for filer backend
|
||||
- **Monitor filer health** - critical for IAM operations
|
||||
- **Implement alerts** for IAM storage issues
|
||||
|
||||
### Capacity Planning
|
||||
- **Estimate IAM data size**: Roles + Policies + Sessions
|
||||
- **Plan for growth**: Active sessions scale with user count
|
||||
- **Monitor filer disk usage**: `/seaweedfs/iam/` path
|
||||
- **Set up log rotation**: For IAM audit logs
|
||||

||||

## Summary
|
||||
|
||||
The distributed IAM system solves critical consistency issues in multi-instance deployments by:
|
||||
|
||||
- **Centralizing IAM state** in SeaweedFS filer
|
||||
- **Ensuring consistency** across all gateway instances
|
||||
- **Maintaining performance** with configurable storage backends
|
||||
- **Supporting scalability** for any number of gateway instances
|
||||
|
||||
For production deployments with multiple S3 gateway instances, **always use filer-based storage** for all IAM components.
