运行Chainlink节点-无法连接到数据库 [英] Running a Chainlink Node - Can't connect to database

问题描述

在macOS上使用docker-desktop.

Using docker-desktop on macOS.

我正在尝试按照此页面上的说明运行节点.

数据库名称为 node ，与用户名 node 相同.用户有权访问数据库，并且可以使用 psql 客户端登录.

The database name is node, which is the same as the username: node. The user has access to the database and can log in using psql client.

我在.env文件中尝试过的连接字符串:

Connection strings I've tried in the .env file:

postgresql://node@localhost/node
postgresql://node:password@localhost/node
postgresql://node:password@localhost:5432/node
postgresql://node:password@127.0.0.1:5432/node
postgresql://node:password@127.0.0.1/node

当我运行启动命令: cd〜/.chainlink-kovan&&docker run -p 6688:6688 -v〜/.chainlink-kovan:/chainlink -it --env-file = .env smartcontract/chainlink local n ，在macOS上使用docker-desktop，我得到以下堆栈跟踪:

When I run the start command: cd ~/.chainlink-kovan && docker run -p 6688:6688 -v ~/.chainlink-kovan:/chainlink -it --env-file=.env smartcontract/chainlink local n , using docker-desktop on macOS, I get the following stack trace:

有人知道我该如何解决吗?

Does anyone know how I can resolve this?

推荐答案

问题出在docker网络上.

The problem is with docker networking.

将-网络主机添加到docker run命令中，以便:

Add --network host to the docker run command so that it is:

cd ~/.chainlink-kovan && docker run -p 6688:6688 -v ~/.chainlink-kovan:/chainlink -it --env-file=.env smartcontract/chainlink --network host local n

这解决了该问题.
