Module 1 - Preparing Configuration & Basic Setup

In this module, we’ll prepare the configuration for your L2 and set up the basic environment needed to get started.

Step 1: Prepare Your Configuration

Before setting up your L2, you need to decide on a few key parameters:

1. Choose a Chain ID that uniquely identifies your chain (will be used for MetaMask setup later)

   • Example: 1002

2. Select a Genesis Address that will receive the initial token supply

   • Example: 0xf0e0CA2704D047A7Af27AafAc6D70e995520C2B2

3. Determine the Genesis Balance (initial token supply)

   • Example: 1000000000000000000000000

Step 2: Download Required Repositories

Clone the Rome setup repository:

git clone --branch v0.3.0 --single-branch https://github.com/rome-labs/rome-setup.git

Step 3: Install Docker Images

For Ubuntu Users

If you’re using Ubuntu, you can directly pull the pre-built Docker images:

docker pull romelabs/rollup-op-geth:v0.3.0
docker pull romelabs/rome-apps:v0.3.0
docker pull romelabs/rome-evm:v0.3.0

For Non-Ubuntu Users

If you’re not using Ubuntu, you’ll need to build the Docker images locally:

# Clone required repositories
git clone --branch v0.3.0 https://github.com/rome-labs/rome-apps.git
git clone --branch v0.3.0 https://github.com/rome-labs/rome-sdk.git
git clone --branch v0.3.0 https://github.com/rome-labs/rome-evm.git

# Build the rome-apps image
docker buildx build -t romelabs/rome-apps:v0.3.0 -f rome-apps/docker/Dockerfile .

For the OP Geth image:

# Clone required repositories
git clone --branch v0.3.0 https://github.com/rome-labs/rome-rollup-clients.git
git clone --branch v0.3.0 https://github.com/rome-labs/op-geth.git

# Build the OP Geth image
docker buildx build -t romelabs/rollup-op-geth:v0.3.0 -f ./rome-rollup-clients/op-geth/Dockerfile .

Step 4: Create Dockerfile for Non-Ubuntu Users

If you’re not using Ubuntu, you’ll need to create a Dockerfile in the rome-rollup-clients/op-geth directory:

FROM --platform=$BUILDPLATFORM golang:1.21.6-alpine AS builder

WORKDIR /app

# Install build dependencies
RUN apk add --no-cache git make gcc musl-dev linux-headers

# Set up cross-compilation
ENV GOOS=linux
ENV GOARCH=amd64
ENV CGO_ENABLED=0

COPY ../../op-geth /app/op-geth
RUN cd op-geth && make geth

FROM --platform=$TARGETPLATFORM nginx:alpine AS run

WORKDIR /app

ENV GETH_NAME="op-geth"
ENV HTTP_PORT="8545"
ENV ENGINE_PORT="8551"
ENV DISCOVERY_PORT="30303"
ENV GETH_BINARY="/usr/local/bin/geth"
ENV GETH_BASE_DATA_DIR="/app/.ethereum"
ENV PORT="3000"

# Install bash, OpenSSL, Node.js, and ts-node
RUN apk add --no-cache bash openssl nodejs npm

# Copy the Geth binary, Nginx configuration, SSL generation script, and other necessary files
COPY --from=builder /app/op-geth/build/bin/geth /usr/local/bin/geth

COPY rome-rollup-clients/op-geth/scripts scripts
COPY rome-rollup-clients/op-geth/nginx.conf /etc/nginx/nginx.conf
COPY rome-rollup-clients/op-geth/run.sh ./run.sh

# Expose ports for Nginx and Express server
EXPOSE 80
EXPOSE 443

# Start Geth, Nginx, and the Express server using ts-node
CMD ["bash", "./run.sh"]
