Can Go's `go get` Command Retrieve Packages from a Local Server Repository?

Can Go Get Work with a Repo on a Local Server?

Yes, Go allows you to retrieve packages and modules from repositories hosted on a local server, even if it's a private repository. Here's how you can use Go get to work with such repositories:

Using GOPATH Mode

If you're using Go in GOPATH mode, you'll need to add the following environment variable to your system:

GOPATH=/path/to/local/repo

This setting will instruct Go to look for packages and modules within the specified local directory. Remember that the path should be the absolute path to the directory containing your git repositories.

Adjusting Go get Command

To retrieve packages or modules from your local repository using Go get, append the following format to the command:

[email protected]:/--path--/--to--/--repository.git//--package--/--or--/--module--

Note:

• Replace --path--/--to--/--repository.git with the relative or absolute path to your local repository.
• Replace --package--/--or--/--module with the name of the package or module you want to retrieve.

Example:

Let's say you have a local repository at /srv/git/liqid.git and want to retrieve the liqid package. You would use the following command:

go get [email protected]:/srv/git/liqid.git/liqid

Caution: Avoid the path@version syntax when using Go in GOPATH mode.

Using Modules

When working with modules, you'll need to ensure that the following environment variable is set:

GOPRIVATE=192.168.xxx.yyy/mygitrepo/*,github.com/my-username/*

Note: Replace 192.168.xxx.yyy/mygitrepo with the IP address and repository name of your local repository. Specify additional private repositories by appending them with commas.

Execute Go get

To retrieve a module from your local repository, use the following command:

go get [email protected]:/--path--/--to--/--module--

Example:

To retrieve the mymodule module from /srv/git/mymodule.git, you would use the following command:

go get [email protected]:/srv/git/mymodule.git

Additional Considerations:

• Ensure that you have SSH key access to your local repository.
• Your local server should have SSHD running.
• If the hostname of your local server does not contain a dot (.), use its IP address instead.
• Go caches downloaded packages and modules in $GOPATH/pkg/mod.
• You can use the go mod download command to explicitly download modules.
• The go env -w GOPRIVATE= syntax can be used to set multiple private repositories.
• For more information and best practices, refer to the official Go documentation.
