Mysql 与my Redis:6379的Redis连接失败-运行种子时getaddrinfo eNotFind

我正在使用Docker进行集装箱服务

我创建了一个种子文件，并通过

npx sequelize cli db:seed:all运行它，然后出现错误：

Sequelize CLI [Node: 13.12.0, CLI: 6.2.0, ORM: 6.5.1]

Loaded configuration file "migrations/config.js".
Using environment "development".
events.js:292
      throw er; // Unhandled 'error' event
      ^

.后遗症

const path = require('path');

module.exports = {
  'config': path.resolve('migrations/config.js'),
  'seeders-path': path.resolve('migrations/seeders'),
  'models-path': path.resolve('migrations/models.js')
};


迁移/model.js

const Sequelize = require('sequelize');
const app = require('../src/app');
const sequelize = app.get('sequelizeClient');
const models = sequelize.models;

module.exports = Object.assign({
  Sequelize,
  sequelize
}, models);


config.js

const app = require('../src/app');
const env = process.env.NODE_ENV || 'development';
const dialect = 'mysql';

module.exports = {
  [env]: {
    dialect,
    url: app.get(dialect),
    migrationStorageTableName: '_migrations'
  }
};


您是在应用程序的Docker Compose容器中运行迁移，还是在Docker主机上运行迁移

从主机的角度来看，没有像
myredis
这样的主机名（它只是Docker覆盖网络中的一个东西，其中包含容器）

因为您已经将Redis端口6379公开给您的主机（事实上是整个世界），所以您应该在主机上使用
localhost:6379
。
我正在我的项目文件夹上运行它。我应该如何修复它？您需要在应用程序容器中运行该命令。请参阅我运行
docker compose exec my web sh
，然后运行
npx sequelize cli db:seed:all
。它起作用了！由于主机开发环境和docker部署环境具有不同的可用主机名，因此您需要确保诸如Redis位置之类的内容是可配置的，可能需要使用环境变量。
const app = require('../src/app');
const env = process.env.NODE_ENV || 'development';
const dialect = 'mysql';

module.exports = {
  [env]: {
    dialect,
    url: app.get(dialect),
    migrationStorageTableName: '_migrations'
  }
};
