运行 Chainlink 节点 - 在 MacOS/OSX 中将本地 Docker/DB 连接到 Docker/Node 问题

Question

Running the Chainlink Node with local docker/postgres in OSX Catalina is quite cumbersome due to failed ORM connection or any others.

Doc used: https://docs.chain.link/docs/running-a-chainlink-node

To check if my local db is indeed working ok. I've ran these commands with successful results:

psql postgresql://suchain:docker@127.0.0.1:5432/chainlink


psql -h localhost -U suchain -d chainlink

What have been tried so far

1. Adding --network host haven't resolve the connection issue

Error Message: Incorrect Usage. flag provided but not defined: -network Incorrect Usage. flag provided but not defined: -network

Note: Tried with --network=host - same result

2. Changing the db_url from 127.0.0.1 to localhost

Error Message: dial error (dial tcp 127.0.0.1:5432: connect: connection refused)

3. Changing the localhost/127.0.0.1 to docker instance name (like pg-docker )

Error Message: hostname resolving error (lookup pg-docker on 192.168.65.1:53: no such host)

Which other options can be used?

Much thanks in advance

Thanks to Patrick. The root cause is the same as in this link

Replacing the db link from localhost/127.0.0.1 to the private/local IP(192.168.0.x) fixed the issue.

FYI: in mac os to find your IP is ifconfig . You'll need to find the en0
