CLI Utility

The CLI utility will help you configure and run a benchmark jobs with Harbor for self-hosted models. It automatically constructs and runs the Harbor job command for your specified benchmark, agent, self-hosted model.

Prerequisites

Install dependencies with uv
```
uv sync
```
Set up a vLLM server, or other Anthropic- and OpenAI-compatible server
Select a benchmark from among the options in Harbor Hub

Run a Benchmark

The following is the minimal configuration needed to run a job with the CLI:

uv run coding-agent-bench run \
    --agent <agent> \
    --dataset <benchmark-name> \
    --model-name <model-name> \
    --server-url <server-url>

For example, to run swe-bench/swe-bench-verified in Claude Code against a self-hosted model:

uv run coding-agent-bench run \
    --agent claude-code \
    --dataset scale-ai/swe-bench-pro \
    --model-name my-model \
    --server-url http://my.server.url

If you want to see a preview of Harbor command that would be run for a given set of arguments without actually running the job, add the --dry-run flag.

Note

Additional configuration options are available, use uv run coding-agent-bench run --help to see them.

Queue Service

The queue service is a FastAPI application that can be deployed on OpenShift to queue and run benchmarks automatically. Benchmark results are stored to MinIO for later review.

sequenceDiagram
    Requestor->>Queue Service: Request Benchmark Run
    Queue Service->>Queue Service: Wait in Queue
    Queue Service->>Openshift Job: Start Benchmark Job
    Openshift Job->>Harbor Orchestrator Pod: Start Harbor Run
    loop For Each Task
        Harbor Orchestrator Pod->>Task Pod: Run Task Pod
        Task Pod->>Harbor Orchestrator Pod: Save Results
    end
    Harbor Orchestrator Pod->>MinIO: Save Benchmark Results
    Harbor Orchestrator Pod->>Openshift Job: Complete
    Queue Service-->>Openshift Job: Poll for completion
    Openshift Job->>Queue Service: Complete
    Queue Service->>Openshift Job: Cleanup
    Queue Service->>Queue Service: Start Next Job

Set up the service

Log in to your cluster and project:

oc login --server=<server> --token=<token>
oc project <project>

Create the MinIO service for artifact storage:
```
oc apply -f deploy/harbor-minio.yml
```
Note: the default username and password are (minioadmin, minioadmin). You can update this in the deployment file if needed.

Create the orchestrator and task service accounts:

oc apply -f deploy/harbor-orchestrator-sa.yml
oc apply -f deploy/harbor-task-sa.yml

Create a secret file named job-queue-secret with an API_KEY and apply it:

apiVersion: v1
kind: Secret
metadata:
  name:  job-queue-secret
stringData:
  API_KEY: <your-api-key>
type: Opaque

Create the queue service:

oc apply -f deploy/job-queue-service.yml

Get the route for the deployed service:

oc get route job-queue-route --output jsonpath='{.spec.host}'

Check that the application is live by visiting the docs:

export JOB_QUEUE_URL="https://$(oc get route job-queue-route --output jsonpath='{.spec.host}')"
open $JOB_QUEUE_URL/docs

Use the service

Queue up a new benchmark task:

curl -X POST $JOB_QUEUE_URL/jobs -d '{"job_name": "test", "agent": "pi", "dataset": "swe-bench/swe-bench-verified", "model_name": "qwen3.6-27b", "server_url": "<server-url>", "n_tasks": 1}' -H "Content-Type: application/json" -H "X-API-Key: <your-api-key>"

{
    "message":"Job created.",
    "job_id":"b5ef13c8-8909-4bf1-b5b1-43354e9f395c", 
    ... 
}

View the queued/running/completed tasks:

open $JOB_QUEUE_URL/ui

Or list them from the API:

curl $JOB_QUEUE_URL/jobs -H "X-API-Key: <your-api-key>"

Cancel a running or queued job:

curl -X DELETE $JOB_QUEUE_URL/jobs/<job_id> -H "X-API-Key: <your-api-key>"

Harbor Command Examples

Prerequisites:

Install Harbor
Set up a vLLM server, or other Anthropic- and OpenAI-compatible server
Set your benchmark in your environment from among the options in Harbor Hub, e.g.:
```
export BENCHMARK='swe-bench/swe-bench-verified'
```
If you need to filter tasks in your benchmark by name, add the -i flag with your glob pattern to your harbor run command, e.g. -i "*ansible*"
