[Errno 111] Connection refused, [Errno 99] Cannot assign requested address

I first pulled the container:

docker pull ghcr.io/bmoscon/cryptostore:latest

I then try to run it using the following command:

docker run -e EXCHANGE='COINBASE' \
           -e CHANNELS='trades,ticker,l2_book' \
           -e SYMBOLS='BTC-USD,ETH-USD' \
           -e BACKEND='POSTGRES' \
           -e DATABASE='cryptostore' \
           -e HOST='localhost' \
           -e PORT=5432 \
           -e USER='postgres' \
           -e PASSWORD='mypassword' \
            ghcr.io/bmoscon/cryptostore:latest

However, I'm getting this error:

Task exception was never retrieved

Am I missing something?

I am also having issues, seems like networking is a issue, I am still learning docker so finding it a bit difficult sadly.

version: '3'
services:
redis:
image: "redis:latest"
ports:
- "6379:6379"
cryptostore:
image: "ghcr.io/bmoscon/cryptostore:latest"

environment:
- EXCHANGE='COINBASE'
- CHANNELS='trades'
- SYMBOLS='BTC-USD'
- BACKEND='REDIS'
- HOST='localhost'
- PORTS='6379'

documents-cryptostore-1 | raise ValueError('Invalid backend specified')
documents-cryptostore-1 | ValueError: Invalid backend specified

Resulting in the value error invalid backend specified

@bmoscon Can we get we your input on troubleshooting DB connection? I'm running a local Postgresql server.

I also found that the TCP example with the following command freezes the container with no outputs:

docker run -e EXCHANGE='COINBASE' \
           -e CHANNELS='trades' \
           -e SYMBOLS='BTC-USD' \
           -e BACKEND='TCP' \
           -e HOST='tcp://127.0.0.1' \
           -e PORT=8080 \
           cryptostore:latest

Thanks your help!

I will try to implement that.

I have a suggestion, for the port, try to do -p PORT=8080:8080 instead

you need to set the networking up correctly in docker. see https://docs.docker.com/network/
