Run a node with Docker

Environment

Ubuntu/CentOS and other systems (including Windows 10 Professional Edition, similar commands) with Docker installed, and docker is running.

Run a node

Run the following command to run the node:

$ sudo docker run --restart=always \
    --name starcoin-main \
    -d -p 9880:9880 \
    -v /data/starcoin/:/data/starcoin/ \
    starcoin/starcoin \
    /starcoin/starcoin \
    -n main \
    -d /data/starcoin \
    --disable-metrics true \
    --stratum-address 0.0.0.0 --stratum-port 9880 \
    --miner-thread 0

Hint:

  • If you don't need to start the mining pool function, you can remove -p 9880:9880, and the last parameter --stratum-address 0.0.0.0 --stratum-port 9880;
  • -n main: Specify the main network main, the test network can be changed to barnard;
  • --miner-thread 0: The number of mining threads, which can be adjusted by yourself;
