ECONNREFUSED 127.0.0.1:3306到jenkins里面的mysql容器

Question

我正在使用docker-slaves插件在jenkins中创建mysql容器。完整设置在localhost上运行。我无法从node.js脚本连接到mysql容器。

error connecting: Error: connect ECONNREFUSED 127.0.0.1:3306
    at Object.exports._errnoException (util.js:1018:11)
    at exports._exceptionWithHostPort (util.js:1041:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1090:14)

连接脚本如下：

const connection = mysql.createConnection({
  host: mysqlHost,
  user: mysqlUser,
  password: mySqlPassword,
  database: mysqlDb
});

connection.connect((err) => {
  if (err) {
    console.error('error connecting: ' + err.stack);
    //return;
  }
  //console.log('connected as id ' + connection.threadId);
});
