In this guide, we cover docker installation of op-erigon
and op-node
to facilitate the node's synchronization on Sepolia Testnet Network. This method is expected to sync an archive node successfully in days or weeks using the snapshot provided by Testinprod-io
Before you start, make sure that you have your own synced Ethereum Sepolia L1 RPC URL and L1 Consensus Layer Beacon endpoint (e.g. Lighthouse Sepolia) ready
Pre-Requisites
sudo apt update -y && sudo apt upgrade -y && sudo apt autoremove -y
sudo apt install -y wget curl screen git ufw zstd
Setting up Firewall
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow 22/tcp
sudo ufw allow 80
sudo ufw allow 443
Enable Firewall
sudo ufw enable
Install Docker
Run this command to remove any conflicting docker
for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done
Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
Add the repository to ppt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
Install docker
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
# Test docker is working
sudo docker run hello-world
#Install docker compose
sudo apt-get update
sudo apt-get install docker-compose-plugin
# Test the docker version
docker compose version
Setting up a domain name to access RPC
Get the IP address of the host machine, you can use the following command in a terminal or command prompt
curl ifconfig.me
Set an A record for a domain, you need to access the domain's DNS settings and create an A record that points to the IP address of the host machine. This configuration allows users to reach your domain by resolving the domain name to the specific IP address associated with your host machine.
Create Optimism Sepolia directory
mkdir optimism-sepolia && cd optimism-sepolia
Create .env file
sudo nano .env
Paste the following into the file.
EMAIL={YOUR_EMAIL} #Your email to receive SSL renewal emails
DOMAIN={YOUR_DOMAIN} #Domain should be something like rpc.mywebsite.com, e.g. optimism-sepolia.infradao.org
WHITELIST={YOUR_REMOTE_MACHINE_IP} #the server's own IP and comma separated list of IP's allowed to connect to RPC (e.g. Indexer)
LAYER_1_RPC={YOUR_L1_RPC} #Your ready synced L1 Ethereum Sepolia node RPC endpoint
L1_BEACON={YOUR_L1_BEACON} #Your synced L1 CL (Consensus Layer) Beacon endpoint, e.g. Lighthouse (Prysm, Lodestar) Sepolia
Create JWT secret file
mkdir -p /root/data/optimism-sepolia/op-erigon/ && cd /root/data/optimism-sepolia/op-erigon/
openssl rand -hex 32 | tr -d "\n" > "./jwt.hex"
Optional/Recommended: Download OptimismSnapshot
To sync from a snapshot, visit Testinprod-io Node Snapshots page to find a latest OptimismSepolia archive for Op-Erigon: https://snapshot.testinprod.io/.
As downloading a snapshot takes some time it is good idea to run it in a screen session
screen -S erigon
Use aria2c
to download the most recent Optimism Sepolia Op-Erigon Archive Snapshot
cd /root/optimism-sepolia
aria2c --file-allocation=none -c -x 15 -s 15 https://datadirs.testinprod.io/op-sepolia-db-24726201.zst
press ctrl+A and D
to return to previous screen and continue installation
screen -r erigon #will bring you back to monitor downloading progress
You'll need to extract the downloaded snapshot and move its contents to the op-erigon-data
directory, where Docker stores persistent data.
# check sha256sum
sha256sum op-sepolia-db-24726201.zst
# decompress first
zstd --decompress op-sepolia-db-24726201.zst -o mdbx.dat
If you initially tried to sync the node from scratch and are now trying with a snapshot make sure to empty the destination directory first:
cd /var/lib/docker/volumes/op-sepolia-erigon_op-erigon_data/_data
ls
#if directory isn't empty remove contents of chaindata directory
rm -rf ~/chaindata/*
mv /root/optimism-sepolia/mdbx.dat /var/lib/docker/volumes/op-sepolia-erigon_op-erigon_data/_data/chaindata
cd /var/lib/docker/volumes/op-sepolia-erigon_op-erigon_data/_data/chaindata
ls #to check if archive has moved properly
If you haven't started the node yet, create op-erigon-data directory first:
docker volume create op-sepolia-erigon_op-erigon_data
cd /var/lib/docker/volumes/op-sepolia-erigon_op-erigon_data/_data
mv /root/optimism-sepolia/mdbx.dat /var/lib/docker/volumes/op-sepolia-erigon_op-erigon_data/_data/
ls
Launch Optimism Sepolia
cd /root/optimism-sepolia
sudo nano docker-compose.yml

Monitor Logs
Use docker logs
to monitor your op-erigon and op-node. The -f
flag ensures you are following the log output
docker logs op-erigon -f --tail 100
docker logs opnode -f --tail 100
Once your Optimism Sepolia node starts syncing, the logs should look like this:
for op-erigon:

curl --data '{"method":"eth_syncing","params":[],"id":1,"jsonrpc":"2.0"}' -H "Content-Type: application/json" -X POST https://{YOUR_DOMAIN}
The result will return false
if a node is fully synced
Alternatively you can run
curl -d '{"id":0,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest",false]}' \
-H "Content-Type: application/json" https://{YOUR_DOMAIN}
and it will return more details about syncing progress
Sync speed will be highly dependent on your Layer 1 RPC
