Question

我正在使用docker，babel，istanbul，pm2，eslint和其他功能构建节点api样板。我的项目在devmon模式下使用nodemon工作正常，并且在mocha的测试模式下工作正常。但是，当我使用pm2以prod模式运行项目时，docker端口不会绑定。

可在此处找到完整项目https://github.com/apandrade/node-api-boilerplate

在搜索解决方案几天后，我发现不存在任何问题，运行我的项目的情况是我运行docker-compose run --service-ports <service_name>并且docker撰写引用是明确的

docker-compose run命令不会创建服务配置中指定的任何端口。这可以防止端口与已打开的端口发生冲突。如果您确实希望创建服务的端口并将其映射到主机，请指定--service-ports标志：

docker-compose up <service_name>

但是我选择运行import { Component } from '@angular/core'; import { AngularFireAuth } from 'angularfire2/auth'; import { ToastController } from 'ionic-angular'; import { Account } from '../../models/accounts/account.interface'; @Component({ selector: 'app-register-form', templateUrl: 'register-form.component.html' }) export class RegisterFormComponent { account = {} as Account; constructor(private afAuth: AngularFireAuth, private toast: ToastController) { } async register() { try{ const result = await this.afAuth.auth.createUserWithEmailAndPassword(this.account.email, this.account.password); this.toast.create({ message: "Account succesfully created!!", duration: 3000 }).present(); console.log(result); } catch(e){ console.error(e); this.toast.create({ message: e.message, duration: 3000 }).present(); } } }，这对我来说已经足够了，因为我没有特定的需求如何覆盖命令或在不同的端口上只运行一个容器。

Pm2不绑定docker端口
