# fixturenet-optimism Instructions to setup and deploy an end-to-end L1+L2 stack with [fixturenet-eth](https://git.vdb.to/cerc-io/fixturenet-eth-stacks/src/branch/main/stack-orchestrator/stacks/fixturenet-eth) (L1) and [Optimism](https://stack.optimism.io) (L2) We support running just the L2 part of stack, given an external L1 endpoint. Follow the [L2 only doc](./l2-only.md) for the same. ## Setup Clone the stack repo: ```bash laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-eth-stacks laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-optimism-stack ``` Clone required repositories: ```bash # L1 (fixturenet-eth) laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth setup-repositories # L2 (optimism) laconic-so --stack ~/cerc/fixturenet-optimism-stack/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 concerned repositories and re-run the command # The repositories are located in $HOME/cerc by default ``` Build the container images: ```bash # L1 (fixturenet-eth) laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth build-containers # L2 (optimism) laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism build-containers # If redeploying with changes in the stack containers laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth build-containers --force-rebuild laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism build-containers --force-rebuild # If errors are thrown during build, old images used by this stack would have to be deleted ``` Note: this will take >10 mins depending on the specs of your machine, and **requires** 16GB of memory or greater. This should create the required docker images in the local image registry: * cerc/lighthouse * cerc/lighthouse-cli * cerc/fixturenet-eth-genesis-premerge * cerc/fixturenet-eth-geth * cerc/fixturenet-eth-lighthouse * cerc/optimism-contracts * cerc/optimism-op-node * cerc/optimism-l2geth * cerc/optimism-op-batcher * cerc/optimism-op-proposer ## Create a deployment First, create a spec file for the deployment, which will map the stack's ports and volumes to the host: ```bash laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy init --output fixturenet-eth.yml laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism deploy init --map-ports-to-host any-fixed-random --output fixturenet-optimism-spec.yml ``` ### Ports It is usually necessary to expose certain container ports on one or more the host's addresses to allow incoming connections. Any ports defined in the Docker compose file are exposed by default with random port assignments, bound to "any" interface (IP address 0.0.0.0), but the port mappings can be customized by editing the "spec" file generated by `laconic-so deploy init`. In addition, a stack-wide port mapping "recipe" can be applied at the time the `laconic-so deploy init` command is run, by supplying the desired recipe with the `--map-ports-to-host` option. The following recipes are supported: | Recipe | Host Port Mapping | |--------|-------------------| | any-variable-random | Bind to 0.0.0.0 using a random port assigned at start time (default) | | localhost-same | Bind to 127.0.0.1 using the same port number as exposed by the containers | | any-same | Bind to 0.0.0.0 using the same port number as exposed by the containers | | localhost-fixed-random | Bind to 127.0.0.1 using a random port number selected at the time the command is run (not checked for already in use)| | any-fixed-random | Bind to 0.0.0.0 using a random port number selected at the time the command is run (not checked for already in use) | For example, you may wish to use `any-fixed-random` to generate the initial mappings and then edit the spec file to set the `fixturenet-eth-geth-1` RPC to port 8545 and the `op-geth` RPC to port 9545 on the host. Or, you may wish to use `any-same` for the initial mappings -- in which case you'll have to edit the spec to file to ensure the various geth instances aren't all trying to publish to host ports 8545/8546 at once. ### Data volumes Container data volumes are bind-mounted to specified paths in the host filesystem. The default setup (generated by `laconic-so deploy init`) places the volumes in the `./data` subdirectory of the deployment directory. The default mappings can be customized by editing the "spec" file generated by `laconic-so deploy init`. --- Once you've made any needed changes to the spec file, create a deployment from it: ```bash laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy create --spec-file fixturenet-eth.yml --deployment-dir fixturenet-eth-deployment laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism deploy create --spec-file fixturenet-optimism-spec.yml --deployment-dir fixturenet-optimism-deployment # Place them both in the same namespace (cluster) cp fixturenet-eth-deployment/deployment.yml fixturenet-optimism-deployment/deployment.yml ``` ### Env configuration Inside the `fixturenet-eth-deployment` deployment directory, open `config.env` file and set following env variables: ```bash # Allow unprotected txs for Optimism contracts deployment CERC_ALLOW_UNPROTECTED_TXS=true ``` ## Start the stack Start the deployment: ```bash laconic-so deployment --dir fixturenet-eth-deployment start laconic-so deployment --dir fixturenet-optimism-deployment start ``` 1. The `fixturenet-eth` L1 chain will start up first and begin producing blocks 2. The `fixturenet-optimism-contracts` service will configure and deploy the Optimism contracts to L1, exiting when complete. This may take several minutes; you can follow the progress by following the container's logs (see below) 3. The `op-node` and `op-geth` services will initialize themselves (if not already initialized) and start 4. The remaining services, `op-batcher` and `op-proposer` will start ### Logs To list and monitor the running containers: ```bash laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy ps laconic-so --stack ~/cerc/fixturenet-optimism-stack/stack/fixturenet-optimism deploy ps # With status docker ps # Check logs for a container docker logs -f ``` ## Example: bridge some ETH from L1 to L2 Send some ETH from the desired account to the `L1StandardBridgeProxy` contract on L1 to test bridging to L2. We can use the testing account `0xe6CE22afe802CAf5fF7d3845cec8c736ecc8d61F` which is pre-funded and unlocked, and the `cerc/foundry:local` container to make use of the `cast` cli. 1. Note the docker network the stack is running on: ```bash docker network ls # The network name will be something like laconic-[some_hash]_default ``` 2. Set some variables: ```bash L1_RPC=http://fixturenet-eth-geth-1:8545 L2_RPC=http://op-geth:8545 NETWORK= DEPLOYMENT_CONTEXT= ACCOUNT=0xe6CE22afe802CAf5fF7d3845cec8c736ecc8d61F ``` If you need to check the L1 chain-id, you can use: ```bash docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast chain-id --rpc-url $L1_RPC" ``` 3. Check the account starting balance on L2 (it should be 0): ```bash docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast balance $ACCOUNT --rpc-url $L2_RPC" # 0 ``` 4. Read the bridge contract address from the L1 deployment records in the `op-node` container: ```bash # get the container id for op-node NODE_CONTAINER=$(docker ps --filter "name=op-node" -q) BRIDGE=$(docker exec $NODE_CONTAINER cat /l1-deployment/$DEPLOYMENT_CONTEXT/.deploy | jq -r .L1StandardBridgeProxy) # get the funded account's pk ACCOUNT_PK=$(docker exec $NODE_CONTAINER jq -r '.AdminKey' /l2-accounts/accounts.json) ``` 5. Use cast to send some ETH to the bridge contract: ```bash docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast send --from $ACCOUNT --value 1ether $BRIDGE --rpc-url $L1_RPC --private-key $ACCOUNT_PK" ``` 6. Allow a couple minutes for the bridge to complete 7. Check the L2 balance again (it should show the bridged funds): ```bash docker run --rm --network $NETWORK cerc/optimism-contracts:local "cast balance $ACCOUNT --rpc-url $L2_RPC" # 1000000000000000000 ``` ## Clean up To stop all services running in the background, while preserving chain data: ```bash laconic-so deployment --dir fixturenet-optimism-deployment stop laconic-so deployment --dir fixturenet-eth-deployment stop ``` To stop all services and also delete chain data: ```bash laconic-so deployment --dir fixturenet-optimism-deployment stop --delete-volumes laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes ``` ## Troubleshooting * If `op-geth` service aborts or is restarted, the following error might occur in the `op-node` service: ```bash 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: ```bash # 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: ```bash # 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](#deploy) to restart the stopped containers
