# MobyMask v3 Watcher
## Setup
Prerequisite: L2 Optimism Geth RPC endpoint
Clone required repositories:
```bash
laconic-so --stack mobymask-v3 setup-repositories --pull --exclude github.com/cerc-io/mobymask-ui
```
Build the container images:
```bash
laconic-so --stack mobymask-v3 build-containers --exclude cerc/mobymask-ui
```
## Deploy
### Configuration
Create and update an env file to be used in the next step ([defaults](../../config/watcher-mobymask-v3/mobymask-params.env)):
```bash
# External ETH RPC endpoint for contract(s) deployment
CERC_ETH_RPC_ENDPOINT=
# External ETH RPC endpoint used for queries in the watcher
CERC_ETH_RPC_QUERY_ENDPOINT=
# External ETH RPC endpoint used for mutations in the watcher
CERC_ETH_RPC_MUTATION_ENDPOINT=
# External ETH endpoint used by watcher's Nitro node
CERC_NITRO_CHAIN_URL=
# Specify the an account PK for contract deployment
CERC_PRIVATE_KEY_DEPLOYER=
# Base URI for mobymask-app
# (used for generating a root invite link after deploying the contract)
CERC_MOBYMASK_APP_BASE_URI="http://127.0.0.1:3004/#"
# (Optional) Domain to be used in the relay node's announce address
CERC_RELAY_ANNOUNCE_DOMAIN=
# (Optional) Set of relay peers to connect to from the relay node
CERC_RELAY_PEERS=[]
# (Optional) Set of multiaddrs to be avoided while dialling
CERC_DENY_MULTIADDRS=[]
# (Optional) Type of pubsub to be used
CERC_PUBSUB=""
# Set to false for disabling watcher peer to send txs to L2
CERC_ENABLE_PEER_L2_TXS=true
# (Optional) Set already deployed MobyMask contract address to avoid deploying contract in the stack
CERC_DEPLOYED_CONTRACT=
# (Optional) Set already deployed Nitro addresses to avoid deploying them in the stack
CERC_NA_ADDRESS=
CERC_VPA_ADDRESS=
CERC_CA_ADDRESS=
# Specify private key of a funded account for sending txs to L2
CERC_PRIVATE_KEY_PEER=
# Specify private key for the Nitro account
CERC_WATCHER_NITRO_PK=
# (Optional) Set a pre-existing peer id to be used (enables consensus)
# Uses a generated peer id if not set (disables consensus)
CERC_PEER_ID=
# Disable payments to upstream ETH server
CERC_ENABLE_UPSTREAM_PAYMENTS=false
```
* NOTE: If Optimism is running on the host machine, use `host.docker.internal` as the hostname to access the host port
### Deploy the stack
```bash
laconic-so --stack mobymask-v3 deploy --cluster mobymask_v3 --exclude mobymask-app-v3 --env-file <PATH_TO_ENV_FILE> up
```
* To list down and monitor the running containers:
```bash
laconic-so --stack mobymask-v3 deploy --cluster mobymask_v3 --exclude mobymask-app-v3 ps
# With status
docker ps -a
# Check logs for a container
docker logs -f <CONTAINER_ID>
```
* The watcher endpoint is exposed on host port `3001` and the relay node endpoint is exposed on host port `9090`
* Check the logs of the MobyMask contract deployment container to get the deployed contract's address and generated root invite link:
```bash
docker logs -f $(docker ps -aq --filter name="mobymask-1")
```
* Check logs of the Nitro contracts container to get the deployed Nitro contracts' addresses:
```bash
docker exec -it $(docker ps -q --filter name="nitro-contracts") bash -c "cat /app/deployment/nitro-addresses.json"
```
## Clean up
Stop all services running in the background:
```bash
laconic-so --stack mobymask-v3 deploy --cluster mobymask_v3 --exclude mobymask-app-v3 down
```
Clear volumes created by this stack:
```bash
# List all relevant volumes
docker volume ls -q --filter "name=mobymask_v3"
# Remove all the listed volumes
docker volume rm $(docker volume ls -q --filter "name=mobymask_v3")
# WARNING: To avoid changing peer ids for the watcher, `peers_ids` volume can be persisted
# To delete all volumes except for `peers_ids`
docker volume rm $(docker volume ls -q --filter "name=mobymask_v3" | grep -v "peers_ids$")
```
