Golang production web application configuration

问题 For those of you running Go backends in production: What is your stack / configuration for running a Go web application? I haven't seen much on this topic besides people using the standard library net/http package to keep a server running. I read using Nginx to pass requests to a Go server - nginx with Go This seems a little fragile to me. For instance, the server would not automatically restart if the machine was restarted (without additional configuration scripts). Is there a more solid

Git Automatically push to Dev and Production from Central Repository depending on branch pushed

阅读更多关于 Git Automatically push to Dev and Production from Central Repository depending on branch pushed

问题 I am somewhat new to Git only and I have only used it for basic projects with simple setups. Now I am struggling to wrap my head around a more complex setup. I have been up all night Googling but I can't find anything related to how I want to set this up. I have three servers on my network: one for development (dev.example.com), one for production (www.example.com), and another that acts a central stage between the two (central.example.com). I want to create a main (probably bare) Git

How do you deploy Angular apps?

How do you deploy Angular apps once they reach the production phase? All the guides I've seen so far (even on angular.io ) are counting on a lite-server for serving and browserSync to reflect changes - but when you finish with development, how can you publish the app? Do I import all the compiled .js files on the index.html page or do I minify them using gulp? Will they work? Do I need SystemJS at all in the production version? You are actually here touching two questions in one. First one is how to host your application. And as @toskv mentioned its really too broad question to be answered and

How to scale Docker containers in production

阅读更多关于 How to scale Docker containers in production

So I recently discovered this awesome tool, and it says Docker is an open-source project to easily create lightweight, portable, self-sufficient containers from any application. The same container that a developer builds and tests on a laptop can run at scale, in production, on VMs, bare metal, OpenStack clusters, public clouds and more. Let's say I have a docker image which runs Nginx and a website connects to external database. How do I scale the container in production? Update: 2019-03-11 First of all thanks for those who have upvoted this answer over the years. Please be aware that this

问题 I\'d like to use react.min.js from a CDN in production (e.g. https://unpkg.com/react@15.3.1/dist/react.min.js) What is the best way to get Webpack to transform my import React from \'react\' statements into const React = window.React instead of building node_modules/react into the bundle? I\'ve been doing it with resolve.alias like this: In index.html : <head> <script type=\"text/javascript\" src=\"https://unpkg.com/react@15.3.1/dist/react.min.js\"></script> <script type=\"text/javascript\"
