Let´s first check the version we have. The first time you run this command, the polkadot docker image will be downloaded. This takes a bit of time and bandwidth, be patient:
[source, shell]
docker run --rm -it chevdor/polkadot:0.3.0 polkadot --version
docker run --rm -it chevdor/polkadot:0.3.14 polkadot --version
You can also pass any argument/flag that polkadot supports:
[source, shell]
docker run --rm -it chevdor/polkadot:0.3.0 polkadot --name "PolkaDocker"
docker run --rm -it chevdor/polkadot:0.3.14 polkadot --chain alex --name "PolkaDocker"
Once you are done experimenting and picking the best node name :) you can start polkadot as daemon, exposes the polkadot ports and mount a volume that will keep your blockchain data locally:
[source, shell]
docker run -d -p 30333:30333 -p 9933:9933 -v /my/local/folder:/data chevdor/polkadot:0.3.0 polkadot
docker run -d -p 30333:30333 -p 9933:9933 -v /my/local/folder:/data chevdor/polkadot:0.3.14 polkadot --chain alex
Additionally if you want to have custom node name you can add the `--name "YourName"` at the end
[source, shell]
docker run -d -p 30333:30333 -p 9933:9933 -v /my/local/folder:/data chevdor/polkadot:0.3.14 polkadot --chain alex --name "PolkaDocker"
**Note:** The `--chain alex` argument is important and you need to add it to the command line. If you are running older node versions (pre 0.3) you don't need it.
Start a shell session with the daemon:
