The ingenious combination of Docker and Golang "Editor's words" This is a simple repertoire of tips and tricks that show how to make Docker more useful when using the go language. For example, how to use different versions of the Go tool chain to compile go code, how to cross compile to a different platform (and test results!). Or how to make a really small container image. The following article assumes that you have installed the Docker. It doesn't

PrefaceThis is my blog park the first article, write not in place, I hope you guys understand.I have been engaged. NET development work, recently in learning Golang, so think about the process of learning before not how to properly record the learning process. Deeply sorry!Now will golang the learning bit record share, nonsense to this, enter the text below.Note: The development platform for this article an

It has been around a year since he started to work with golang. He has been studying it for himself in his spare time, but he is still mainly limited to grammar and language features. He hasn't used it to write practical projects yet. There are many resources on the Internet to learn about golang syntax and language features. Later, I may write a rough article to

If you are interested in Golang but have not yet begun to get started, this article is for you. Why do you learn Golang? Many of the articles lobbying developers to try Golang.For example, a speech by Golang's main designer, a German spat, a preface to a book by a domestic Golang preacher. I do not want to repeat Dan

First, the preface Golang has a lot of novel characteristics, do not know the use of the time, have not thought about how these features are achieved? Of course you might say, do not understand these features do not seem to affect their use of Golang, you said that there is a reason, but, more understanding of the bottom of the implementation of the principle of the use of

for range, the values of the matcher and feed variables are locked at the same time as the arguments passed into the anonymous function closure. When you use closures to access external variables, ask yourself how this variable will change, and how this change affects the operation of the closure.

We know that the local variable initialization method in Golang (using ": =" to create and assign values) makes it convenient to use variables. However, this is also one of the places where mistakes are easy to make. In particular, this initializer also supports the initialization of multiple variables at the same time, and more particularly, it also supports the original variable assignment and new variable creation and assignment at the same time! T
