# Terraform Provider for 3x-ui

> Manage [3x-ui](https://github.com/MHSanaei/3x-ui) inbounds, clients, panel settings, and Xray configuration as code — backup, migrate, and scale your VPN/proxy fleet without clicking through the panel.

## Why use it

Running 3x-ui in production means dozens of inbounds, hundreds of clients, and Xray configuration that is easy to break. With this provider you can:

- **Treat configuration as code** — your inbound list lives in git, every change is reviewed and versioned.
- **Migrate between servers safely** — restore the panel database to preserve IDs and secrets, then verify it with Terraform.
- **Back up Terraform state** — `terraform state pull` exports only Terraform-managed objects; pair it with a panel database backup for disaster recovery.
- **Scale onboarding** — add 100 clients in a single PR instead of 100 panel clicks.
- **Plan before prod** — `terraform plan` shows exactly what will change before anything ships.

## Without vs with the provider

| Task | Panel UI | This provider |
| --- | --- | --- |
| Add 50 clients | 50 forms, ~30 seconds each | one `for_each`, one `apply` |
| Migrate to a new server | manual re-entry | restore the panel database, then verify with `terraform plan` |
| Audit who has access today | scroll the client list | `git log` on a `.tf` file |
| Roll back a misconfiguration | restore from a JSON backup | `git revert` + `terraform apply` |
| Sync staging ↔ production | export/import JSON, fix conflicts | shared module + per-environment vars |
| Rotate Reality keys on 10 hosts | open 10 panels, click each | one variable change, one apply |

## Quick Start

```hcl
terraform {
  required_providers {
    threexui = {
      source = "batonogov/threexui"
    }
  }
}

provider "threexui" {
  endpoint = "http://localhost:2053"
  username = "admin"
  password = "admin"
}

resource "threexui_inbound" "vless" {
  remark   = "VLESS Reality"
  port     = 443
  protocol = "vless"

vless_settings {
    decryption = "none"
  }

stream_settings {
    network  = "tcp"
    security = "reality"
    reality_settings {
      target       = "www.amazon.com:443"
      server_names = ["www.amazon.com"]
    }
  }

sniffing {
    enabled       = true
    dest_override = ["http", "tls", "quic", "fakedns"]
  }
}

resource "threexui_inbound_client" "client_a" {
  inbound_id = threexui_inbound.vless.id
  email      = "client-a@example.com"
  enable     = true
  flow       = "xtls-rprx-vision"
}
```

## Compatibility

**Support policy:** the provider officially supports every released patch across all supported 3x-ui minor lines — see the compatibility table below. The acceptance matrix exercises each version on every push to `main` and every pull request.

| 3x-ui version | Status |
| --- | --- |
| v3.6.0 | Tested |
| v3.5.0 | Tested |
| v3.4.2 | Tested |
| v3.4.1 | Tested |
| v3.4.0 | Tested |
| v3.3.1 | Tested |
| v3.3.0 | Tested |
| v3.2.8 | Tested |
| v3.2.7 | Tested |
| v3.2.6 | Tested |
| v3.2.5 | Tested |
| v3.2.0 | Tested |
| v3.1.0 | Tested |

Newer protocol features are guarded with `requireMinVersion` and skip automatically on older versions, so the provider runs cleanly across the matrix without per-version forks.

## Guides

In-repo walkthroughs for common operational scenarios:

- [Backup-as-code](docs/guides/backup-as-code.md) — combine reviewed Terraform configuration with state and panel database backups.
- [Migrating 3x-ui between servers](docs/guides/server-migration.md) — restore the panel database on a new VPS, then verify it with Terraform.
- [Onboarding many clients at once](docs/guides/bulk-clients.md) — `for_each` patterns and CSV-driven onboarding.

## Documentation

## Security

The provider handles secrets the panel issues automatically (Reality `privateKey`, WireGuard `secretKey`, client UUIDs, Telegram bot tokens, LDAP passwords). All such fields are marked `Sensitive` and never logged in plaintext. See [SECURITY.md](SECURITY.md) for the full list and for guidance on protecting your Terraform state.

## Development

### Requirements

- Go (version pinned in [`go.mod`](go.mod))
- [Task](https://taskfile.dev/) — task runner
- [golangci-lint](https://golangci-lint.run/welcome/install/) — linter
- [pre-commit](https://pre-commit.com/) — git hooks framework
- Docker — for the local 3x-ui environment

### Commands

```bash
task build        # Build the provider
task fmt          # Format code (gofmt)
task vet          # Run go vet
task lint         # Run golangci-lint
task pre-commit   # Run all checks manually (fmt, vet, lint, build)
task test:unit    # Run unit tests (no Docker / Terraform needed)
task test:acc     # Run acceptance tests (starts docker compose)
task test         # Run unit + acceptance tests
```

### Local environment
