Organize and share knowledge related to domestic deployment of Golang

Golang, as an efficient, reliable, simple and easy-to-use programming language, brings a lot of convenience to developers. As Golang becomes more and more popular in China, more and more developers are beginning to consider how to deploy Golang in China. This article will introduce you to the relevant knowledge of Golang’s domestic deployment.

1. Choose the appropriate deployment method

There are many deployment methods for Golang in China, the common ones are the following:

1. Independent deployment

Independent deployment refers to installing the Golang environment on the server and deploying Golang applications into this environment. This method can give full play to the high performance and efficiency of Golang and is a commonly used deployment method.

2. Container deployment

Container deployment refers to deploying Golang applications into containers using container technologies such as Docker or Kubernetes. The emergence of container technology makes deployment more flexible and easier to manage.

3.PaaS deployment

The PaaS platform can eliminate a lot of operation and maintenance work and leave the deployment and management of applications to the PaaS provider. At present, there are many PaaS platforms in China, such as Alibaba Cloud's container service, Tencent Cloud's container service, etc.

2. The problem of downloading Golang’s domestic dependency packages

The downloading and installation of Golang’s dependency packages is an important part of Golang development, and it often becomes the main problem that hinders the domestic development of Golang. Because Golang's default dependency package download address is golang.org/x/, and golang.org is inaccessible in China. Therefore, other methods need to be used to obtain dependency packages in China.

1. Use domestic mirror sources

Currently, there are many Golang mirror sources in China, such as goproxy.io, goproxy.cn, gocenter, etc. These mirror sources provide download services for Golang dependency packages, which can greatly simplify the process of downloading dependency packages.

2. Manually download the dependency package

If you still cannot download the dependency package using the mirror source, you need to download the dependency package manually. You can manually download dependency packages through code hosting platforms such as GitHub and GitLab, and then place them in the src directory of the Golang environment.

3. Golang compilation problems in domestic network environment

Since Golang compilation needs to be connected to the Golang official website, Golang compilation is likely to encounter network problems in the domestic network environment. Specifically, Golang prompts a network error when compiling some dependent packages, causing the compilation to fail.

In order to solve this problem, the following methods can be used:

1. Upgrade to the latest version of Golang

The latest version of Golang will automatically handle network errors as much as possible , older versions of Golang require manual setting of custom agents, which is more cumbersome.

2. Set the proxy

In Go mod mode, set the GOPROXY environment variable in the command line to the proxy server address used, and you can use the proxy to download dependency packages. For example, it can be set to the following command:

export GOPROXY=https://goproxy.io

3. Offline compilation

If you encounter problems with the domestic network environment, you cannot compile online. , you can choose to perform offline compilation. The steps for offline compilation are: first download the required dependency packages, and then compile them locally.

Summary:

The domestic deployment of Golang is a problem that requires attention, but it is not unsolvable. Golang's domestic deployment problems can be well solved by choosing an appropriate deployment method and solving dependency package download problems and network environment problems.
