- Find the Docker Container ID:
List all running Docker containers to find the ID of the peer container you are interested in:
docker ps
- Access the Container's Filesystem:
Once you have the Container ID, you can access its filesystem using the following command:
docker exec -it <container_id> /bin/sh
- Navigate to Ledger Data:
Inside the container, you can navigate to the directories where Hyperledger Fabric stores the ledger data. The default paths are often as follows:
For the world state:
/var/hyperledger/production/ledgersData/stateLeveldb
For the blockchain data:
<!-- Open folder -->
cd /var/hyperledger/production/ledgersData/chains
<!-- Read block data -->
cat /var/hyperledger/production/ledgersData/chains/chains/mychannel/blockfile_000000
