Run Juno with a snapshot​
1. Download the snapshot​
First, download a snapshot from one of the provided URLs:
wget -O juno_mainnet.tar https://juno-snapshots.nethermind.dev/files/mainnet/latest
2. Prepare a directory​
Ensure you have a directory to store the snapshots. We will use the $HOME/snapshots directory:
mkdir -p $HOME/snapshots
3. Extract the snapshot​
Extract the contents of the downloaded .tar file into the directory:
tar -xvf juno_mainnet.tar -C $HOME/snapshots
4. Run Juno​
Run the Docker command to start Juno and provide the path to the snapshot using the db-path option:
docker run -d \
--name juno \
-p 6060:6060 \
-v $HOME/snapshots/juno_mainnet:/snapshots/juno_mainnet \
nethermind/juno \
--http \
--http-port 6060 \
--http-host 0.0.0.0 \
--db-path /snapshots/juno_mainnet
--eth-node <YOUR ETH NODE>
info
Replace <YOUR ETH NODE> with the WebSocket endpoint of your Ethereum node. For Infura users, your address should be: wss://mainnet.infura.io/ws/v3/your-infura-project-id. Ensure you use the WebSocket URL (ws/wss) instead of the HTTP URL (http/https).
