# laconicd-full-node

Instructions for running a laconicd testnet full node and joining as a validator

## Prerequisites

* Minimum hardware requirements:

  ```bash
  RAM: 8-16GB
  Disk space: 200GB
  CPU: 2 cores
  ```

* Testnet genesis file (file or an URL) and peer node addresses

## Setup

* Clone the stack repo:

  ```bash
  laconic-so fetch-stack git.vdb.to/cerc-io/testnet-laconicd-stack
  ```

* Clone required repositories:

  ```bash
  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node setup-repositories
  ```

* Build the container images:

  ```bash
  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node build-containers
  ```

  This should create the following docker images locally:

  * `cerc/laconic2d`

## Create a deployment

* Create a spec file for the deployment:

  ```bash
  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node deploy init --output laconic-full-node-spec.yml
  ```

* Edit `network` in the spec file to map container ports to host ports as required:

  ```bash
  ...
  network:
    ports:
      laconicd:
        - '6060:6060'
        - '26657:26657'
        - '26656:26656'
        - '9473:9473'
        - '9090:9090'
        - '1317:1317'
  ```

* Create a deployment from the spec file:

  ```bash
  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconicd-full-node deploy create --spec-file  laconic-full-node-spec.yml --deployment-dir laconic-full-node-deployment
  ```

* (Optional) Copy over the genesis file (`.json`) to data directory in deployment (`laconic-full-node-deployment/data/laconicd-data/tmp`):

  ```bash
  # Example
  mkdir -p laconic-full-node-deployment/data/laconicd-data/tmp
  cp genesis.json laconic-full-node-deployment/data/laconicd-data/tmp/genesis.json
  ```

## Configuration

* Inside the deployment directory, open `config.env` file and set following env variables:

  ```bash
  # Comma separated list of nodes to keep persistent connections to
  # Example: "node-1-id@node-1-host:26656,node-2-id@node-2-host:26656"
  CERC_PEERS=""

  # Optional

  # A custom human readable name for this node (default: TestnetNode)
  CERC_MONIKER=

  # Network chain ID (default: laconic_9000-1)
  CERC_CHAIN_ID=

  # Genesis file URL
  # Not required if a genesis file is placed in the config data directory in previous steps
  CERC_GENESIS_FILE_URL=

  # Output log level (default: info)
  CERC_LOGLEVEL=
  ```

## Start the deployment

```bash
laconic-so deployment --dir laconic-full-node-deployment start
```

## Check status

* To list down and monitor the running containers:

  ```bash
  # With status
  docker ps -a

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

* Check the sync status of your node:

  ```bash
  docker exec -it <LACONICD_CONTAINER_ID> status | jq .sync_info
  ```

## Join as testnet validator

<!-- TODO import a funded account / create an account and get it funded -->

<!-- TODO create a validator-->

## Clean up

* Stop all services running in the background:

  ```bash
  # Stop the docker containers
  laconic-so deployment --dir laconic-full-node-deployment stop
  ```

* To stop all services and also delete data:

  ```bash
  # Stop the docker containers
  laconic-so deployment --dir laconic-full-node-deployment stop --delete-volumes

  # Remove deployment directory (deployment will have to be recreated for a re-run)
  rm -r laconic-full-node-deployment
  ```
