This guide helps you rebuild your Pharos Testnet node while preserving your existing validator identity (node info). This is useful when resetting the database but retaining validator keys and configuration.
1️⃣ Stop and Backup the Existing Node
Copy docker stop pharos-testnet
mv /data/testnet /data/testnet_bak
docker rm pharos-testnet 2️⃣ Start a Fresh Node Container
Copy docker run -d --name pharos-testnet \\
-v /data/testnet:/data \\
-p 18100:18100 -p 18200:18200 -p 19000:19000 \\
public.ecr.aws/k2g7b7g1/pharos/testnet:63b85b6b 3️⃣ ⏳ Wait for Initial Sync (~3 minutes)
Do not run docker stop or docker-compose down during this step.
You can check sync progress using:
Copy curl 127.0.0.1:18100/ \\
-X POST \\
-H "Content-Type: application/json" \\
--data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}' 4️⃣ Stop the Node and Restore Node Identity
Copy docker stop pharos-testnet Replace new config with the backup node info:
Copy rm -rf /data/testnet/pharos-node/domain/light/data/
rm -rf /data/testnet/pharos-node/domain/light/certs/
rm -rf /data/testnet/resources/
mv /data/testnet_bak/pharos-node/domain/light/data/ /data/testnet/pharos-node/domain/light/data/
mv /data/testnet_bak/pharos-node/domain/light/certs/ /data/testnet/pharos-node/domain/light/certs/
mv /data/testnet_bak/resources/ /data/testnet/resources/ 5️⃣ Restart and Finalize
Copy docker start pharos-testnet Wait ~3 minutes again for sync to resume. You can check status using:
Copy curl 127.0.0.1:18100/ \\
-X POST \\
-H "Content-Type: application/json" \\
--data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}' 6️⃣ Clean Up Backup
Copy rm -rf /data/testnet_bak
