issue can be worked around by running

Story: Writing Scripts with Go

This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.

Why Go is good for scripting?

While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

Introduction

Here are the steps I used to add vue-play to my vue-cli webpack project. These instructions assume a directory structure like this:

Why I Recommend to Avoid Using the go-kit Library

There is a trending 'microservice' library called go-kit. I've been using the go-kit library for a while now. The library provide a lot of convenience integrations that you might need in your service: with service discovery with Consul, distributed tracing with Zipkin, for example, and nice logic utilities such as round robin client side load balancing, and circuit breaking. It is also providing a way to implement communication layer, with support of RPC and REST.

      - LISTEN_PORT=8388
      - REMOTE_ADDR=your.ss-server.ip.or.domain
      - REMOTE_PORT=29900

【译】如何将 s6-svscan 用作初始进程

点击这里阅读原文。

2015 年 6 月 17 日之后，如果你是 Linux 用户，你可以使用 s6-linux-init 包来帮助你实现同样的目标！尽管如此，还是请你首先阅读本篇文档，以理解 s6-linux-init 的工作内容。

将 s6-svscan 用作初始进程是可行的。但这并不意味着你可以直接通过 s6-svscan 引导，因为它还无法胜任完整的初始化系统所应做地全部工作。正确地替换掉初始进程，还需要对其工作内容做更多地理解。
