Ergopad

Set of docker containers combined to create a React/MaterialUI frontend, REST API backend, assembler to interact with smart contracts and supporting services like ergonode, redis and postgres.

Currently, worker (celery) is disabled (intended to automate the aggregator eventually). Flower and PGAdmin are used mainly for dev to explore postgres and celery.

Quick Start

If docker and docker-compose v2 are setup, then:
docker compose up -d

• Services should be available on the ports below.
• Front-end may need attention as it tends to run outside docker (can cd to frontend and yarn dev to run in OS and not in docker; may need to install node/npm/yarn/next/etc..)

Verify > ergonode - http://localhost:9053/panel/ (api key in assembler config)
> pgadmin - http://localhost:5050/ (check on postegres)
> flower - http://localhost:5555/ (check on celery)
> assembler - http://localhost:8080/state (check logs to verify running)
> backend - http://localhost:8000/api/ping (hello: world)
> frontend - http://localhost:3000/dashboard (will take time to compile next/ts)

Note: The first time ergonode is setup, it will need to sync the network, which can take at least a few hours (depending on system), and this can be seen in the ergonode:9053/panel screen.

Common troubleshooting steps:

To see what's going on inside container, can use docker GUI if have one, or:
docker logs <service> -n 50 -f

To stop, start or restart a service:
docker compose <stop/start/restart> <service>
Note: compose is optional here, but useful sometimes

To see what's going on inside a service:
docker exec -it <service> bash
Note: bash is the commend to run inside the container. This is a common shell, but may also use sh, csh, etc..

Docker Hints

1. In root, run docker-compose up --build to initiate backend
2. Run docker ps to get the container ID of the "dashboard-project_server" container, and copy it
3. Run docker exec -it {CONTAINER ID} bash to open a bash terminal to that docker container
4. In that terminal, type alembic upgrade head to migrate the database.
5. Navigate to http://localhost:8000/api/docs and test the various endpoints to ensure the backend is up and running

Frontent Hints

Now, to initiate frontend, you need to have NPM installed in your dev enviroment.

1. Navigate to frontend directory.
2. Use npm install to set up
3. Install yarn if you don't already have it with npm install -g yarn
4. Run yarn dev to initiate the dev server
5. Browse to htttp://localhost:3000 to check that the server is up and running.

Development

You can now change anything in the frontend folder and it will automatically refresh the website for you.

To make changes to backend, it's a good idea to reset the docker with ctrl-C if you're following the docker logs, or docker-compose stop in a fresh terminal. Then run docker-compose up to start it again.

If alembic upgrade head doesnt work, or you just need a fresh database, run docker-compose down

TODO

NGINX is setup and should really be the only container accessed from the outside world. This document is intended more for development, not production.

There are comments in some places with tag, TODO: that indicate work may be incomplete.
