fixturenet-optimism

Instructions to setup and deploy an end-to-end L1+L2 stack with fixturenet-eth (L1) and Optimism (L2)

We support running just the L2 part of stack, given an external L1 endpoint. Follow l2-only for the same.

Setup

Clone required repositories:

laconic-so --stack fixturenet-optimism setup-repositories

# If this throws an error as a result of being already checked out to a branch/tag in a repo, remove the repositories mentioned below and re-run the command

Checkout to the required versions and branches in repos:

# Optimism
cd ~/cerc/optimism
git checkout v1.0.3

Build the container images:

laconic-so --stack fixturenet-optimism build-containers

This should create the required docker images in the local image registry:

• cerc/go-ethereum
• cerc/lighthouse
• cerc/fixturenet-eth-geth
• cerc/fixturenet-eth-lighthouse
• cerc/foundry
• cerc/optimism-contracts
• cerc/optimism-l2geth
• cerc/optimism-op-node
• cerc/optimism-op-batcher
• cerc/optimism-op-proposer

Deploy

Deploy the stack:

laconic-so --stack fixturenet-optimism deploy up

The fixturenet-optimism-contracts service may take a while (~15 mins) to complete running as it:

1. waits for the 'Merge' to happen on L1
2. waits for a finalized block to exist on L1 (so that it can be taken as a starting block for roll ups)
3. deploys the L1 contracts

To list down and monitor the running containers:

laconic-so --stack fixturenet-optimism deploy ps

# With status
docker ps

# Check logs for a container
docker logs -f <CONTAINER_ID>

Clean up

Stop all services running in the background:

laconic-so --stack fixturenet-optimism deploy down

Clear volumes created by this stack:

# List all relevant volumes
docker volume ls -q --filter "name=.*l1_deployment|.*l2_accounts|.*l2_config|.*l2_geth_data"

# Remove all the listed volumes
docker volume rm $(docker volume ls -q --filter "name=.*l1_deployment|.*l2_accounts|.*l2_config|.*l2_geth_data")

Troubleshooting

• If op-geth service aborts or is restarted, the following error might occur in the op-node service:

  WARN [02-16|21:22:02.868] Derivation process temporary error       attempts=14 err="stage 0 failed resetting: temp: failed to find the L2 Heads to start from: failed to fetch L2 block by hash 0x0000000000000000000000000000000000000000000000000000000000000000: failed to determine block-hash of hash 0x0000000000000000000000000000000000000000000000000000000000000000, could not get payload: not found"
  

• This means that the data directory that op-geth is using is corrupted and needs to be reinitialized; the containers op-geth, op-node and op-batcher need to be started afresh:

  WARNING: This will reset the L2 chain; consequently, all the data on it will be lost

  • Stop and remove the concerned containers:

    # List the containers
    docker ps -f "name=op-geth|op-node|op-batcher"
    
    # Force stop and remove the listed containers
    docker rm -f $(docker ps -qf "name=op-geth|op-node|op-batcher")
    

  • Remove the concerned volume:

    # List the volume
    docker volume ls -q --filter name=l2_geth_data
    
    # Remove the listed volume
    docker volume rm $(docker volume ls -q --filter name=l2_geth_data)
    

  • Re-run the deployment command used in Deploy to restart the stopped containers

Known Issues

• fixturenet-eth currently starts fresh on a restart
• Resource requirements (memory + time) for building the cerc/foundry image are on the higher side
  • cerc/optimism-contracts image is currently based on cerc/foundry (Optimism requires foundry installation)
