![]() ![]() In Artifactory, a combination of a remote repository for, a remote Go module repository that points to private GitHub repos (for private modules) and a local Go module repository can be combined into a single virtual repository, to access as a single unit. In this way, immutability and availability can be guaranteed for both public and private Go modules. ![]() Private modules are also cached in a repository from their VCS repos. Public modules are cached locally by proxying a public GOPROXY in a binary repository manager like JFrog Artifactory. ![]() Private GOPROXYĪ private GOPROXY is one you install to store both public and private Go modules on your own infrastructure. Another alternate is to use GONOSUMDB variable that includes references to private go modules.While this configuration enables the Go client to resolve both public and private module dependencies, it doesn’t enforce immutability or availability requirements for private modules. This use of GOPRIVATE also ensures that your use of these private modules isn’t “leaked” through requests to a public GOPROXY & checksum database server on an open network. To use the this public GOPROXY along with private modules, set the Golang environment variables: For example, you may want to use to retrieve all open-source modules but request private modules only from your company’s servers. Some users use the GOPRIVATE environment variable to specify a list of paths that must bypass GOPROXY and GOSUMDB and download private modules directly from those VCS repos. Typically, GoLang projects make use of both open-source and private module dependencies. The UI at pkg.go.dev enables you to search for modules and provides some basic statistics. In addition to fulfilling downloads, a public GOPROXY can also provide GoLang developers more detailed information about the modules it holds. Downloads from a public GOPROXY can be much faster than directly from the VCS, by downloading a module archive file. The above setting redirects all module download requests to the Go module repository maintained by the Golang team. To use a public GOPROXY, set the Golang environment variable to its URL: Most, like are provided to the Golang developer community for free. It hosts open-source Go modules that have been made available from third parties in publicly accessible VCS project repositories. Public GOPROXYĪ public GOPROXY is a centralized repository available to Golang devs across the globe. There are different ways to use GOPROXY, depending on the source of go modules dependencies you expect to use. The GOPROXY’s cache also helps ensure the module is always available, even if the original in the VCS repo is destroyed. By returning the module from the GOPROXY’s cache, it always provides the same code for a requested version, even if the module has been improperly modified more recently in the VCS repo. Using a GOPROXY for module dependencies helps enforce the immutability requirement. Setting a GOPROXY for your Golang development or CI environment redirects Go module download requests to a cache repository. While these scenarios are considered to be bad practice, they do occur frequently. Modules can be wiped out by the author or versions can be edited. While the above workflow was popularly used, it lacked the two fundamental requirements of a deterministic and secure build and development process: immutability & availability. Private dependencies must authenticate with the VCS system where they are stored to download the module source files. Dependencies from a third party are typically downloaded from public source repos. When developing in Golang before the GOPROXY era, module dependencies were downloaded directly from their source repositories in VCS systems such as GitHub, Bitbucket, Bazaar, Mercurial or SVN. What Is a GOPROXY?Ī GOPROXY controls the source of your Go module downloads and can help assure builds are deterministic and secure. Let’s take a look at what a GOPROXY is for, and some of the ways you can set one up for a system that is fast, reliable, and secure. Starting with Go 1.13, Go modules are the standard package manager in Golang, automatically enabled on installation along with a default GOPROXY.īut with that GOPROXY as well as your own Go module packages you need to keep secure from public view, what kind of configuration should you choose? How can you keep your public and private Golang resources from becoming a tangled knot? Note: This blog has been updated to reflect the sunsetting of JFrog GoCenter. ![]()
