将 Firebase 函数与 Google Cloud SQL MYSQL 连接时出现 ECONNREFUSED

Question

Here's my config.json from Sequelize:

{
  "development": {
    "username": "root",
    "password": "xxxx",
    "database": "xxxx",
    "host": "127.0.0.1",
    "dialect": "mysql",
    "dialectOptions": {
      "socketPath": "/cloudsql/xxx:xxxx:xxxx"
    }
  },
  ...
}

And I deployed at Firebase Functions with firebase deploy .

But when I do something with database, it shows SequelizeConnectionRefusedError: connect ECONNREFUSED /cloudsql/xxx:xxx:xxx

Answer 1

Here's a working config:

const sequelize = new Sequelize("test-db", "test-user", "mypassword", {
  dialect: "mysql",
  host: "/cloudsql/PROJECT:REGION:INSTANCE",
})

Sequalize wants a host that points to the Unix socket.

No other configuration on the Firebase Functions side is necessary.
