Usage

Command flags

See PD Configuration Flags.

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.

# Set correct HostIP here.
export HostIP="192.168.199.105"

pd-server --name="pd" \
          --data-dir="pd" \
          --client-urls="http://${HostIP}:2379" \
          --peer-urls="http://${HostIP}:2380" \
          --log-file=pd.log

Using curl to see PD member:

curl http://${HostIP}:2379/pd/api/v1/members

{
    "members": [
        {
            "name":"pd",
            "member_id":"f62e88a6e81c149",
            "peer_urls": [
                "http://192.168.199.105:2380"
            ],
            "client_urls": [
                "http://192.168.199.105:2379"
            ]
        }
    ]
}

A better tool httpie is recommended:

http http://${HostIP}: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: 673
Content-Type: application/json; charset=UTF-8

{
    "members": [
        {
            "client_urls": [
                "http://192.168.199.105:2379"
            ],
            "member_id": "f62e88a6e81c149",
            "name": "pd",
            "peer_urls": [
                "http://192.168.199.105:2380"
            ]
        }
    ]
}

Docker

You can use the following command to build a PD image directly:

docker build -t tikv/pd .

Or you can also use following command to get PD from Docker hub:

docker pull pingcap/pd

Run a single node with Docker:

# Set correct HostIP here.
export HostIP="192.168.199.105"

docker run -d -p 2379:2379 -p 2380:2380 --name pd tikv/pd \
          --name="pd" \
          --data-dir="pd" \
          --client-urls="http://0.0.0.0:2379" \
          --advertise-client-urls="http://${HostIP}:2379" \
          --peer-urls="http://0.0.0.0:2380" \
          --advertise-peer-urls="http://${HostIP}:2380" \
          --log-file=pd.log

Cluster

As a component of TiKV project, PD needs to run with TiKV to work. The cluster can also include TiDB to provide SQL services. You can refer Deploy a TiDB Cluster Using TiUP or TiDB in Kubernetes Documentation for detailed instructions to deploy a cluster.
