💡 Key Innovations

1. Unified Docker Provisioning

Problem: Standalone autoscaler and runner launcher had their own Docker implementations, causing code duplication.

Solution: Runner module uses docker_kit.py for all container operations:

  • docker_kit.run_container() for launching runners
  • docker_kit.list_containers() for monitoring
  • docker_kit.stop_container() for cleanup

Result:

  • Zero code duplication
  • Consistent behavior
  • Single source of truth
  • Easier to maintain

2. Multi-Interface Access

Problem: Autoscaler was only accessible via standalone script.

Solution: Integrated into unified architecture with three interfaces:

CLI (for manual management):

ipfs-accelerate runner start --owner myorg

MCP (for programmatic access):

await mcp.call_tool('runner_start_autoscaler', {owner: 'myorg'});

Python API (for custom integration):

from ipfs_accelerate_py.kit.runner_kit import get_runner_kit
kit = get_runner_kit()
kit.start_autoscaler()

3. Dashboard Integration

Problem: No way to monitor or control autoscaler from dashboard.

Solution: All 7 runner tools exposed through MCP server:

  • Start/stop autoscaler from dashboard
  • View real-time status and metrics
  • Monitor workflow queues
  • Manage runner containers
  • Provision runners on-demand

🔧 Usage Examples

Basic Autoscaling

# Start monitoring all accessible repos
ipfs-accelerate runner start --background

# Check status
ipfs-accelerate runner status

# View workflow queues
ipfs-accelerate runner list-workflows

# Stop when done
ipfs-accelerate runner stop

Organization Monitoring

# Monitor specific organization
ipfs-accelerate runner start \
  --owner myorg \
  --interval 60 \
  --max-runners 20 \
  --background

Dashboard Control

// Start autoscaler
const result = await mcp.call_tool('runner_start_autoscaler', {
  owner: 'myorg',
  poll_interval: 60,
  max_runners: 20,
  background: true
});

// Get real-time status
const status = await mcp.call_tool('runner_get_status', {});
console.log(`Active runners: ${status.data.active_runners}`);
console.log(`Queued workflows: ${status.data.queued_workflows}`);

// List workflow queues
const workflows = await mcp.call_tool('runner_list_workflows', {});
workflows.data.forEach(queue => {
  console.log(`${queue.repo}: ${queue.total_workflows} workflows`);
});

Custom Python Logic

from ipfs_accelerate_py.kit.runner_kit import get_runner_kit, RunnerConfig

# Create config
config = RunnerConfig(
    owner='myorg',
    max_runners=20,
    poll_interval=60
)

# Initialize
kit = get_runner_kit(config)

# Start autoscaler in background
kit.start_autoscaler(background=True)

# Custom logic: provision extra for priority repos
priority_repos = ['owner/critical-app']
queues = kit.get_workflow_queues()

for queue in queues:
    if queue.repo in priority_repos and queue.pending > 0:
        token = kit.generate_runner_token(queue.repo)
        container_id = kit.launch_runner_container(queue.repo, token)
        print(f"Provisioned priority runner: {container_id}")

From Standalone Autoscaler

Before:

python scripts/utils/github_autoscaler.py --owner myorg --interval 60

After:

Option 1 - CLI:

ipfs-accelerate runner start --owner myorg --interval 60

Option 2 - Python:

from ipfs_accelerate_py.kit.runner_kit import get_runner_kit, RunnerConfig
kit = get_runner_kit(RunnerConfig(owner='myorg', poll_interval=60))
kit.start_autoscaler()

Option 3 - MCP/JavaScript:

await mcp.call_tool('runner_start_autoscaler', {
  owner: 'myorg',
  poll_interval: 60
});
