Instructions to setup and deploy Uniswap app on Urbit

Build and deploy:

• Urbit
• Uniswap app

Setup

Clone required repositories:

laconic-so --stack uniswap-urbit-app setup-repositories --pull

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

Build the container images:

laconic-so --stack uniswap-urbit-app build-containers

Create a deployment

First, create a spec file for the deployment, which will map the stack's ports and volumes to the host:

laconic-so --stack uniswap-urbit-app deploy init --output uniswap-urbit-app-spec.yml

Ports

Edit uniswap-urbit-app-spec.yml such that it looks like:

stack: uniswap-urbit-app
deploy-to: compose
network:
  ports:
    urbit-fake-ship:
      - '8080:80'
    ipfs:
     - '4001'
     - '8081:8080'
     - 0.0.0.0:5001:5001
volumes:
  urbit_app_builds: ./data/urbit_app_builds
  urbit_data: ./data/urbit_data
  ipfs-import: ./data/ipfs-import
  ipfs-data: ./data/ipfs-data

Note: Skip the ipfs ports if using an externally running IPFS node, set via config.env, below.

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:

laconic-so --stack uniswap-urbit-app deploy create --spec-file uniswap-urbit-app-spec.yml --deployment-dir uniswap-urbit-app-deployment

Set env variables

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

# App to be installed (Do not change)
CERC_URBIT_APP=uniswap

# External RPC endpoints
# https://docs.infura.io/getting-started#2-create-an-api-key
CERC_INFURA_KEY=

# Uniswap API GQL Endpoint
# Set this to GQL proxy server endpoint for uniswap app
# (Eg. http://localhost:4000/v1/graphql - in case stack is being run locally with proxy enabled)
# (Eg. https://abc.xyz.com/v1/graphql - in case https://abc.xyz.com is pointed to the proxy endpoint)
CERC_UNISWAP_GQL=/apps/uniswap-proxy/v1/graphql
CERC_UNISWAP_API=/apps/uniswap-proxy/v2

# Optional

# Whether to enable app installation on Urbit
# (just builds and uploads the glob file if disabled) (Default: true)
CERC_ENABLE_APP_INSTALL=

# Whether to run the proxy GQL server
# (disable only if proxy not required to be run) (Default: true)
CERC_ENABLE_PROXY=

# Proxy server configuration
# Used only if proxy is enabled

# Upstream API URL
# (Eg. https://api.example.org)
CERC_PROXY_UPSTREAM=https://api.uniswap.org

# Origin header to be used in the proxy
# (Eg. https://app.example.org)
CERC_PROXY_ORIGIN_HEADER=https://app.uniswap.org

# IPFS configuration

# IFPS endpoint to host the glob file on
# (Default: http://ipfs:5001 pointing to in-stack IPFS node)
CERC_IPFS_GLOB_HOST_ENDPOINT=

# IFPS endpoint to fetch the glob file from
# (Default: http://ipfs:8080 pointing to in-stack IPFS node)
CERC_IPFS_SERVER_ENDPOINT=

Start the stack

Start the deployment:

laconic-so deployment --dir uniswap-urbit-app-deployment start

• List and check the health status of all the containers using docker ps and wait for them to be healthy

• Run the following to get login password for Urbit web interface:

  laconic-so deployment --dir uniswap-urbit-app-deployment exec urbit-fake-ship "curl -s --data '{\"source\":{\"dojo\":\"+code\"},\"sink\":{\"stdout\":null}}' http://localhost:12321"
  
  # Expected output: "<PASSWORD>\n"%
  

• Open the Urbit web UI at http://localhost:8080 and use the PASSWORD from previous step to login

• The uniswap app is not available when starting stack for the first time. Check urbit-fake-ship logs to see that app has installed:

  laconic-so deployment --dir uniswap-urbit-app-deployment logs -f
  
  # Expected output:
  # laconic-3ccf7ee79bdae874-urbit-fake-ship-1    | docket: fetching %http glob for %uniswap desk
  # laconic-3ccf7ee79bdae874-urbit-fake-ship-1    | ">="">="uniswap app installed
  

• The uniswap app will be now visible at http://localhost:8080

Clean up

To stop all uniswap-urbit-app services running in the background, while preserving data:

# Only stop the docker containers
laconic-so deployment --dir uniswap-urbit-app-deployment stop

# Run 'start' to restart the deployment

To stop all uniswap-urbit-app services and also delete data:

# Stop the docker containers
laconic-so deployment --dir uniswap-urbit-app-deployment stop --delete-volumes

# Remove deployment directory (deployment will have to be recreated for a re-run)
rm -r uniswap-urbit-app-deployment
