# Connect Agent
OpenFlare Agent runs on proxy nodes. It handles registration, heartbeat, configuration sync, OpenResty file writes, validation, reload, rollback, and self-update.
## Authentication
| Method | Use case |
| --- | --- |
| `agent_token` | The node already exists or has a dedicated credential |
| `discovery_token` | First-time auto-registration; Server exchanges it for a node token |
At least one of them is required.
## Install Script
```bash
curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
--server-url http://your-server:3000 \
--agent-token YOUR_AGENT_TOKEN
```
Or with discovery:
```bash
curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
--server-url http://your-server:3000 \
--discovery-token YOUR_DISCOVERY_TOKEN
```
## Configuration Example
```json
{
"server_url": "http://127.0.0.1:3000",
"agent_token": "replace-with-node-auth-token",
"data_dir": "./data",
"openresty_container_name": "openflare-openresty",
"openresty_docker_image": "openresty/openresty:alpine",
"openresty_observability_port": 18081,
"observability_replay_minutes": 15,
"heartbeat_interval": 10000,
"request_timeout": 10000
}
```
Without `openresty_path`, Agent uses Docker OpenResty by default.
## Run from Source
```bash
cd openflare_agent
export LOG_LEVEL='info'
go run ./cmd/agent -config /path/to/agent.json
```
## Uninstall
```bash
curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/uninstall-agent.sh | bash
```
