Starting from this release, the exact same syntax that you use with the Go client is now supported which is excellent news for Go developers and DevOps engineers building Go pipelines. 1.26.0 introduced a number of major changes to the way the JFrog CLI calls the Go client. The JFrog CLI will also publish modules that aren’t in Artifactory yet to Artifactory so that they are available for future builds. In turn, Artifactory will look at both its local and remote repositories and serve the modules to you. The JFrog CLI uses the Go client to try and resolve all Go modules from Artifactory. When you use the JFrog CLI to build your Go apps, it will work as a wrapper around the Go client. While this is excellent for pretty much all developers, the only thing you cannot do is publish new Go modules to Artifactory. In turn, Artifactory will look at both its local and remote repositories to serve the modules to you. The Go client will try to resolve all Go modules from Artifactory. Using the GOPROXY environment variable has almost the same behavior as using goc. You can set your GOPROXY environment variable to point to your virtual repository (for example, export for a virtual repository called “go”). You can use either the GOPROXY environment variable or the JFrog CLI. To resolve modules from Artifactory, you have two options. The next step is to create a virtual repository that contains the remote repository for GoCenter. If you want to use Artifactory to resolve and cache your Go modules, you need to create a remote repository for GoCenter. Use Artifactory to resolve your Go modules Using goc is great if you only build open source software and don’t need to keep your own builds somewhere safe. goc will look at GoCenter first and if the module isn’t in GoCenter it will get the module from its original place (like GitHub). The current behavior of the Go client is to look at one single proxy and fail your build if not all modules are resolved from there. This means it bypasses other proxies like Artifactory. The goc utility automatically sets the GOPROXY environment variable to GoCenter. Use Artifactory and set up a remote and virtual repository for your own modules together with the modules proxied from GoCenter.Use a utility called goc, which builds Go apps using modules from GoCenter without requiring any need for manual setup.Since you want to have immutable builds, you have two ways to get your modules from GoCenter and we’ll look at both of them: You can now add Go modules you depend on by running “go get". To get the template and create the outline of the app, you’ll need to run two commands: For example, to create a module called “/retgits/bla” the command would be go mod init /retgits/bla. To create a Go module, run the following command: go mod init. However, if you still choose to put your code in your $GOPATH and want to use Go modules you’ll have to set the GO111MODULE to on. From Go 1.11, it’s no longer recommended to put your source code in your $GOPATH. How to create a Go module?ĭepending on where you put your source code you might need to set the environment variable GO111MODULE. Without Go modules, immutability cannot be guaranteed. If you depend on other software, it needs to immutable preventing developer, that decides to experiment a little, to make changes. You can build your project using version 1.2 of a module and the next morning someone else in your team might use version 1.3. Without Go modules, your project will never truly have repeatable builds. If you don’t use Go modules, but use vendoring instead, the time it takes to clone and build your project will increase making it more time-consuming to push your latest update to production. Let’s start with a quick recap of some of my other blog posts on why we need Go modules in the first place. Go also has a vibrant community that produces a pretty stellar list of Go apps and modules and with the rise of public registries, like GoCenter, you can have immutable dependencies too. In the latest StackOverflow Insights survey, Go was named as the third most wanted language.

UPDATE: As of – GoCenter central repository has been sunset and all features deprecated.
