How to install Docker?
Follow the below guides to install docker on Desktop -
Follow the below guide to install docker on cloud -
Please do not run a testnet and a mainnet nodes simultaneously on the same machine.
If you have been running a Stader node on the testnet and plan to use the same machine/system for running a node on Mainnet, please ensure that you terminate your testnet node and delete the testnet Stader directory before starting the Mainnet node setup. This is crucial to avoid conflicts with directories, ports, and potential unknown issues. Please use the following commands to perform the necessary actions:
To terminate the testnet node, use:
~/bin/stader-cli service terminateTo delete the testnet Stader directory, use:
rm -rf ~/.stader
