How to Make a Package Available for \'go get\' on a Personal Git Repository?

Using "go get" on a Personal Git Repository: A Comprehensive Guide

The Challenge

Attempting to make a package available for "go get" on a personal Git repository often results in the error message "unrecognized import path." This article provides a comprehensive solution to this issue.

Understanding the META Tag

Go requires a META tag in the root HTML page of the Git repository that specifies the package's import path and repository URL. The syntax is as follows:

<meta name="go-import" content="import_path git repo_url">

Setting Up the Server

For the "go get" feature to work, the server hosting the Git repository must be configured to return the META tag when a request is made with the "?go-get=1" parameter.

Recommended nginx Configuration

The following nginx rewrite rule can be used to achieve this:

location ~ "(/[^/]+/[^/]+)(/.*)?" {
    if ($arg_go-get = "1") {
            echo '<meta name="go-import" content="my.domain.com git git+ssh://[email protected]">';
    }
    try_files $uri $uri/index.html $uri.html @gitlab;
}

This rule assumes SSH access to the Git repository. If HTTPS is used, modify the URL accordingly.

Example META Tag

Requesting "http://mygit.server/group/project?go-get=1" should return the following META tag:

<meta content="mygit.server/group/project git git+ssh://[email protected]/group/project.git" name="go-import">

Testing the Package

After configuring the server, you can verify if the package is available for "go get" by running:

<code class="Bash">go get example.com/user/package</code>

This command should successfully download and install the package.
