# PD [](https://github.com/tikv/pd/actions/workflows/check.yaml) [](https://github.com/tikv/pd/actions/workflows/pd-tests.yaml) [](https://github.com/tikv/pd/actions/workflows/tso-consistency-test.yaml) [](https://github.com/tikv/pd/releases) [](https://goreportcard.com/report/github.com/tikv/pd) [](https://codecov.io/gh/tikv/pd) PD is the abbreviation for Placement Driver. It manages and schedules [TiKV](https://github.com/tikv/tikv) clusters. PD supports fault-tolerance by embedding [etcd](https://github.com/etcd-io/etcd). [](https://github.com/pingcap/tidb-map/blob/master/maps/contribution-map.md#pd-placement-driver-for-tikv) If you're interested in contributing to PD, see [CONTRIBUTING.md](./CONTRIBUTING.md). For more contributing information about where to start, click on the contributor icon above. ## Build 1. Make sure [*Go*](https://golang.org/) (version 1.20) is installed. 2. Use `make` to install PD. PD is installed in the `bin` directory. ## Usage PD can be configured using command-line flags. For more information, see [PD Configuration Flags](https://docs.pingcap.com/tidb/stable/command-line-flags-for-pd-configuration). ### Single node with default ports You can run `pd-server` directly on your local machine. If you want to connect to PD from outside, you can let PD listen on the host IP. ```bash # Set HOST_IP to the address you want to listen on export HOST_IP="192.168.199.105" pd-server --name="pd" \ --data-dir="pd" \ --client-urls="http://${HOST_IP}:2379" \ --peer-urls="http://${HOST_IP}:2380" \ --log-file=pd.log ``` Using `curl` to view PD members: ```bash curl http://${HOST_IP}:2379/pd/api/v1/members { "members": [ { "name": "pd", "member_id": 15980934438217023866, "peer_urls": [ "http://192.168.199.105:2380" ], "client_urls": [ "http://192.168.199.105:2379" ], "deploy_path": "/", "binary_version": "v6.1.3", "git_hash": "1a4e975892512a97fb0e5b45c9be69aa76148793" } ] } ``` You can also use [httpie](https://github.com/jkbrzt/httpie) to call the API: ```bash http http://${HOST_IP}:2379/pd/api/v1/members Access-Control-Allow-Headers: accept, content-type, authorization Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE Access-Control-Allow-Origin: * Content-Length: 1003 Content-Type: application/json; charset=UTF-8 Date: Mon, 12 Dec 2022 13:46:33 GMT { "members": [ { "name": "pd", "member_id": 15980934438217023866, "peer_urls": [ "http://192.168.199.105:2380" ], "client_urls": [ "http://192.168.199.105:2379" ], "deploy_path": "/", "binary_version": "v6.1.3", "git_hash": "1a4e975892512a97fb0e5b45c9be69aa76148793" } ] } ``` ### Docker You can choose one of the following methods to get a PD image: - Build locally: ```bash docker build -t pingcap/pd . ``` - Pull from Docker Hub: ```bash docker pull pingcap/pd ``` Then you can run a single node using the following command: ```bash # Set HOST_IP to the address you want to listen on export HOST_IP="192.168.199.105" docker run -d -p 2379:2379 -p 2380:2380 --name pd pingcap/pd \ --name="pd" \ --data-dir="pd" \ --client-urls="http://0.0.0.0:2379" \ --advertise-client-urls="http://${HOST_IP}:2379" \ --peer-urls="http://0.0.0.0:2380" \ --advertise-peer-urls="http://${HOST_IP}:2380" \ --log-file=pd.log ``` ### Cluster As a component of the TiKV project, PD needs to run with TiKV to work. The cluster can also include TiDB to provide SQL services. For detailed instructions to deploy a cluster, refer to [Deploy a TiDB Cluster Using TiUP](https://docs.pingcap.com/tidb/stable/production-deployment-using-tiup) or [TiDB on Kubernetes Documentation](https://docs.pingcap.com/tidb-in-kubernetes/stable).
