Uniswap v3

Instructions to deploy Uniswap v3 watcher stack (watcher + uniswap-v3-info frontend app) using laconic-stack-orchestrator

Prerequisites

Access to uniswap-watcher-ts.
This deployment expects core services to be running; specifically, it requires ipld-eth-server RPC and GQL endpoints. Update the upstream.ethServer endpoints in the watcher config files accordingly:
```
[upstream]
  [upstream.ethServer]
    gqlApiEndpoint = "http://ipld-eth-server.example.com:8083/graphql"
    rpcProviderEndpoint = "http://ipld-eth-server.example.com:8082"
```
uni-watcher and uni-info-watcher database dumps (optional).

Setup

Clone / pull required repositories:

$ laconic-so setup-repositories --include vulcanize/uniswap-watcher-ts,vulcanize/uniswap-v3-info --git-ssh --pull

Build watcher and info app container images:
```
$ laconic-so build-containers --include cerc/watcher-uniswap-v3,cerc/uniswap-v3-info
```
This should create the required docker images in the local image registry.

Deploy

(Optional) Initialize the watcher database with existing database dumps if available:

Start the watcher database to be initialized:

$ laconic-so deploy-system --include watcher-uniswap-v3 up uniswap-watcher-db

Find the watcher database container's id using docker ps and export it for further usage:
```
$ export CONTAINER_ID=<CONTAINER_ID>
```

Load watcher database dumps:

# uni-watcher database
$ docker exec -i $CONTAINER_ID psql -U vdbm uni-watcher < UNI_WATCHER_DB_DUMP_FILE_PATH.sql

# uni-info-watcher database
$ docker exec -i $CONTAINER_ID psql -U vdbm uni-info-watcher < UNI_INFO_WATCHER_DB_DUMP_FILE_PATH.sql

Start all the watcher and info app services:

$ laconic-so deploy-system --include watcher-uniswap-v3 up

Check that all the services are up and healthy:
```
$ docker ps
```
- The uni-info-watcher GraphQL Playground can be accessed at http://localhost:3004/graphql
- The frontend app can be accessed at http://localhost:3006

Clean up

To stop all the services running in background:

$ laconic-so deploy-system --include watcher-uniswap-v3 down
