### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

* Ensure you have **Go** installed and configured on your local machine.

{% hint style="info" %}
**ADDITIONAL INFORMATION**

Depending on your environment, you may need to run additional commands. Go to the [Go installation](https://go.dev/doc/install) guide for more information.
{% endhint %}

* Ensure you have access to a Harness account with the appropriate permissions to create registries and connectors.
* Ensure you have [Harness CLI](/harness-ai/use-harness-platform/automation/cli/install.md) installed and running in your local machine.

### Create a Go Artifact Registry <a href="#create-a-go-artifact-registry" id="create-a-go-artifact-registry"></a>

Create Go Artifact Registry in Harness
{% endembed %}
{% endtab %}

{% tab title="Step-by-Step" %}

1. Navigate to the Artifact Registry module in your Harness project.
2. Click on **New Artifact Registry**.
3. In the Registry Type list, select **Go Registry**.
4. Provide a Registry Name.
   * The registry name must start with a letter and can include lowercase alphanumeric characters, underscores (`_`), periods (`.`), and hyphens (`-`).
5. Optionally, add a Description and Labels for better organization.
6. Choose visibility between **Public** and **Private**.
7. Click **Create Registry** to finalize.
   {% endtab %}
   {% endtabs %}

{% hint style="info" %}
**PRIVATE GO REGISTRY**

This registry will serve as your private Go registry within Harness.
{% endhint %}

### Configure an Upstream Proxy (Optional) <a href="#configure-an-upstream-proxy-optional" id="configure-an-upstream-proxy-optional"></a>

An upstream proxy allows your registry to fetch Go modules from external sources if they are not available locally.

Configure Go Upstream Proxy in Harness
{% endembed %}
{% endtab %}

{% tab title="Step-by-Step" %}

#### Create an upstream proxy

1\. In the Artifact Registry module, click the dropdown next to \*\*New Artifact Registry\*\* and select \*\*Upstream Proxy\*\*. 2. Choose \*\*Go Registry\*\* as the proxy type. 3. Click \*\*Create Proxy\*\* to establish the connection.

#### Configure the upstream proxy in your registry

1\. In the Artifact Registry module, select an existing Go Artifact Registry. 2. Select the \*\*Configuration\*\* tab. 3. Under \*\*Advanced (Optional)\*\*, select \*\*Configure Upstream\*\*. 4. Select from the list of compatible proxies to add them to your registry. 5. Click \*\*Save\*\* to save the configuration.
{% endtab %}
{% endtabs %}

{% hint style="info" %}
**UPSTREAM PROXY CACHING**

If a Go module isn’t found in your Harness registry, the upstream proxy fetches it from an external registry like proxy.golang.org, reducing duplication and improving module resolution.

### Publish & Install Go modules <a href="#publish-and-install-go-modules" id="publish-and-install-go-modules"></a>

#### Authenticate the Go client <a href="#authenticate-the-go-client" id="authenticate-the-go-client"></a>

1. In your Harness Go Artifact Registry, click **Setup Client**.
2. Click **Generate Token** to generate an identity token.
3. Export your token with the following command:

```bash
export GOPROXY="https://<email_address>:<TOKEN>@pkg.app.harness.io/pkg/<harness_account_id>/<go-registry-name>/go"
```

#### Publish a Go package <a href="#publish-a-go-package" id="publish-a-go-package"></a>

* Run the following command (using [Harness CLI](/harness-ai/use-harness-platform/automation/cli/install.md)) from your project’s root directory to publish your Go package into your Harness Registry:

```bash
hns ar push go <REGISTRY_NAME> <ARTIFACT_VERSION> --pkg-url pkg.app.harness.io
```

#### Install a Go package <a href="#install-a-go-package" id="install-a-go-package"></a>

* Install your package using `go get`:

```bash
go get <ARTIFACT_NAME>@<VERSION>
```

***

### Troubleshooting <a href="#troubleshooting" id="troubleshooting"></a>

* Slow downloads or timeouts. Verify network egress to the Harness endpoint. If needed, configure `GOPROXY` explicitly and ensure your client respects it.
* Authentication errors. Ensure your `go env -w GOPRIVATE` and token setup are correctly applied.
* Package not found. Confirm the package was published to the correct Harness registry and that the version tag exists in the repository.
