This page describes how to create connections to GitHub Enterprise Cloud and create links to GitHub Enterprise Cloud repositories. You can complete these tasks using the Google Cloud console, or the Google Cloud CLI.
These instructions are for application developers, platform administrators, and security managers who want to use GitHub Enterprise Cloud source code repositories with Google. Specifically, you can use GitHub Enterprise Cloud repositories with [Gemini Code Assist](https://docs.cloud.google.com/gemini/docs/codeassist/code-customization-overview). To learn more about Developer Connect, see [Developer Connect overview](https://docs.cloud.google.com/developer-connect/docs/overview). ## Before you begin 1. Ensure that you have access to an account on [GitHub Enterprise Cloud.](https://github.com) To help keep your team's work secure, we recommend that you complete the tasks in this guide using a bot account or an account shared by your team, not a personal account. 2. Ensure that you own a GitHub Enterprise Cloud repository, or have admin-level permissions on a shared repository. 3. Optional: Create a [customer-managed encryption key](https://docs.cloud.google.com/kms/docs/create-key) (CMEK) for encrypting the authentication secrets that Developer Connect creates. 4. Optional: To use the command-line instructions in this guide, complete the following steps: 1. Install the [Google Cloud CLI](https://docs.cloud.google.com/sdk/docs/install-sdk). If you've installed gcloud CLI previously, make sure you have the latest available version by running `gcloud components update`. 2. Create a [Developer Connect service account](https://docs.cloud.google.com/developer-connect/docs/access-control#sa) by running the following command, where PROJECT_ID is your [Google Cloud project ID](https://docs.cloud.google.com/resource-manager/docs/creating-managing-projects#identifying_projects): ```bash gcloud beta services identity create \ --service=developerconnect.googleapis.com \ --project=PROJECT_ID ``` ### Required roles To get the permissions that you need to create connections and links, ask your administrator to grant you the following IAM roles: - If you aren't the project owner: [Developer Connect Admin](https://docs.cloud.google.com/iam/docs/roles-permissions/developerconnect#developerconnect.admin) (`roles/developerconnect.admin`) on your user account. - If you plan to use a CMEK to encrypt the secrets that Developer Connect creates: [Cloud KMS CryptoKey Encrypter/Decrypter](https://docs.cloud.google.com/iam/docs/roles-permissions/cloudkms#cloudkms.cryptoKeyEncrypterDecrypter) (`roles/cloudkms.cryptoKeyEncrypterDecrypter`) on the Secret Manager Service Account. - If you plan to use the gcloud CLI to complete the steps in this guide: [Secret Manager Admin role](https://docs.cloud.google.com/iam/docs/roles-permissions/secretmanager#secretmanager.admin) (`roles/secretmanager.admin`) on the Developer Connect Service Account. - If you plan to use the Google Cloud console to complete the steps in this guide: [Project IAM Admin](https://docs.cloud.google.com/iam/docs/roles-permissions/resourcemanager#resourcemanager.projectIamAdmin) (`roles/resourcemanager.projectIamAdmin`) on your user account. For more information about granting roles, see [Manage access to projects, folders, and organizations](https://docs.cloud.google.com/iam/docs/granting-changing-revoking-access). You might also be able to get the required permissions through [custom roles](https://docs.cloud.google.com/iam/docs/creating-custom-roles) or other [predefined roles](https://docs.cloud.google.com/iam/docs/roles-overview#predefined). > [!NOTE] > **Note:** When you have the Project IAM Admin (`roles/resourcemanager.projectIamAdmin`) role, the Google Cloud console can automatically grant necessary permissions on your behalf. If your administrator won't allow you to have the Project IAM Admin role, then ask your administrator to grant Secret Manager Admin (`roles/secretmanager.admin`) on the Developer Connect Service Account (`service-{projectNumber}@gcp-sa-devconnect.iam.gserviceaccount.com`). ## Create a connection This section describes how to create a connection between Developer Connect and GitHub Enterprise Cloud. If you're using the Google Cloud console, then you can also start adding links to repositories as you finish setting up your connection. To create a new GitHub Enterprise Cloud connection, select one of the following options: ### Console Initiate a connection by completing the following steps: 1. In the Google Cloud console, open **Developer Connect**. [Go to Developer Connect](https://console.cloud.google.com/developer-connect/connections)
Developer Connect displays the **Git repositories** page. - **If you see a list of source code management providers:** Start configuring your first connection by selecting a source code management provider. Click **Connect** on the GitHub Enterprise Cloud card. - **If you see a table listing existing connections** : Set the source code management provider by clicking **Create connection** \> **GitHub Enterprise Cloud**. The **Create Connection** page opens. 2. For **Region** , choose a [region](https://docs.cloud.google.com/developer-connect/docs/locations) for your connection resources. 1. For **Name**, enter a name for your new connection. 3. Activate the **Enable a data residency compliant connection** checkbox to make this connection compliant with [data residency requirements](https://docs.cloud.google.com/developer-connect/docs/data-residency). GitHub connections created using the Google Cloud console are data-residency compliant if you activate this checkbox when you create the connection. When you do this, Developer Connect [creates a GitHub app](https://docs.cloud.google.com/developer-connect/docs/data-residency) When you create a GitHub connections using Google Cloud CLI, those connections are not data-residency compliant. All other connection types are data-residency compliant. 4. Click **Show more** to see optional configuration settings. 1. Optional: In the **Encryption** section, select a [CMEK key](https://docs.cloud.google.com/kms/docs/key-management-service) to encrypt Secret Manager secrets that Developer Connect creates. 2. Optional: By default, Developer Connect can act as a proxy for Git calls to GitHub Enterprise Cloud. To disable this option, clear the **Enable Developer Connect proxy** checkbox. 5. Click **Continue**. 6. Click **I understand and continue** to agree to share your GitHub OAuth token with Developer Connect and store it in Secret Manager. 7. Sign in to GitHub if prompted to do so. 8. Click **Authorize Developer Connect** to allow the Google Developer Connect app to access your GitHub account. If you don't see this prompt, then authorization has already been granted on this account. 9. If you selected **Enable a data residency compliant connection**, you're prompted to create a GitHub app. 1. Provide a name for this GitHub app. 2. Click **Create GitHub app**. 3. Select the target where you want to install the app (your GitHub account or an organization). 4. Select the repositories for which to install the GitHub app, or **All repositories** , and click **Install**. 5. Select the repositories to link for this connection, and click **Ok**. 6. Click **Link**. GitHub creates a token and Developer Connect stores it in your Google Cloud project as a Secret Manager secret. For more information on managing secrets, see [view secret details](https://docs.cloud.google.com/secret-manager/docs/view-secret-details). If you enabled data residency, you now have a GitHub app, which you can manage by clicking **Manage installation** on the **Connection details** page. ### Configure the connection The following steps are required if you have not activated the **Enable a data residency compliant connection** checkbox. Grant permissions on your GitHub account and link to repositories using the following instructions. The prompts you see in your web browser depend on whether the GitHub account already has the Developer Connect GitHub app installed. In the Developer Connect dialog, complete the following steps: **If you see a list of GitHub accounts, install the app and link repositories by completing these steps:** 1. Choose the GitHub account you want to use. 2. Select one or more repositories you want to grant access to. **If you see a prompt to re-use an existing app installation, choose where to configure the app by completing these steps:** 1. Click **GitHub Account** to see accounts that have the Google Developer Connect app installed. If you see the account you want to use, choose it by clicking **Confirm**. 2. If you don't see the account that you want to use, do the following: 1. Choose **Install the GitHub App on another GitHub account** and click **Confirm**. 2. Follow the GitHub steps to permit app installation. 3. Select one or more repositories you want to grant access to. When the dialog closes, the app installation is complete. Once the connection is created, the **Link repositories** page appears. Complete the following steps to link repositories to your connection: 1. In the list of available repositories, select the repositories you want to use. 2. Click **OK**. 3. Click **Link**. Your connection is added to the **Connections** page and your repository links are added to the **Repositories** page in the Google Cloud console. You can [add more links to existing connections](https://docs.cloud.google.com/developer-connect/docs/connect-github-enterprise-cloud#link-repos) at any time. ### gcloud The following tasks require some actions in your web browser. Initiate a connection by completing the following steps: 1. Run the [`gcloud developer-connect connections create`](https://docs.cloud.google.com/sdk/gcloud/reference/developer-connect/connections/create) command to create a connection to GitHub Enterprise Cloud. If you have [data residency enabled](https://docs.cloud.google.com/developer-connect/docs/data-residency): gcloud developer-connect connections create CONNECTION_NAME \ --location=REGION \ --github-enterprise-config-app=DEVELOPER-CONNECT \ --github-enterprise-config-host-uri=HOST_URI \ --git-proxy-config-enabled If you don't have data residency enabled: gcloud developer-connect connections create CONNECTION_NAME \ --location=REGION \ --github-config-app=DEVELOPER-CONNECT \ --github-config-host-uri=HOST_URI \ --git-proxy-config-enabled Replace the following: - CONNECTION_NAME: a name for your connection. - REGION: the region for your connection. - HOST_URI: the URI for the host you want to connect to. If you have data residency enabled, this will use a domain that includes your subdomain (`YOUR_SUBDOMAIN`.ghe.com). If you don't have data residency enabled, this will use `github.com`. - `--git-proxy-config-enabled`: an optional flag that enables Developer Connect to act as a proxy for Git calls to GitHub Enterprise Cloud. This capability is in [Preview](https://cloud.google.com/products/#product-launch-stages). A connection name is created. 2. Finish creating the connection by installing the Developer Connect GitHub app. Run the following command to get the URI for app installation: gcloud developer-connect connections describe CONNECTION_NAME \ --location=REGION Replace the following: - CONNECTION_NAME: the name of your connection. - REGION: the region of your connection. Developer Connect returns a link to install the Google Developer Connect app in a browser window. Copy this link. 3. Open the link in a web browser. 4. Click **I understand and continue** to agree to share your GitHub OAuth token with Developer Connect and store it in Secret Manager. 5. Sign in to GitHub if prompted to do so. 6. Click **Authorize Developer Connect** to allow the Google Developer Connect app to access your GitHub account. If you don't see this prompt, authorization has already been granted on this account. GitHub creates a token and Developer Connect stores it in your Google Cloud project as a Secret Manager secret. To view your secrets, [list secrets in Secret Manager](https://docs.cloud.google.com/secret-manager/docs/view-secret-details). You may revoke access to Developer Connect through GitHub at any time. ### Configure the connection Grant permissions on your GitHub account and link to repositories using the following instructions. The prompts you see in your web browser depend on whether the GitHub account already has the Developer Connect GitHub app installed. In the Developer Connect dialog, complete the following steps: **If you see a list of GitHub accounts, install the app and link repositories by completing these steps:** 1. Choose the GitHub account you want to use. 2. Select one or more repositories you want to grant access to. **If you see a prompt to re-use an existing app installation, choose where to configure the app by completing these steps:** 1. Click **GitHub Account** to see accounts that have the Google Developer Connect app installed. If you see the account you want to use, choose it by clicking **Confirm**. 2. If you don't see the account that you want to use, do the following: 1. Choose **Install the GitHub App on another GitHub account** and click **Confirm**. 2. Follow the GitHub steps to permit app installation. 3. Select one or more repositories you want to grant access to. When the dialog closes, the app installation is complete. ### Verify the connection Verify the creation of your GitHub Enterprise Cloud connection by running the following command: gcloud developer-connect connections describe CONNECTION_NAME \ --location=REGION Replace the following: - CONNECTION_NAME: the name of your connection. - REGION: the region for your connection. Developer Connect returns a status in the `installationState` field. If the value of this field is `COMPLETE`, your app installation is done. Otherwise, Developer Connect returns a URI to return you to configuration in the browser. Once your connection is completed, choose which repositories to link by following the instructions in [Add repository links to existing connections](https://docs.cloud.google.com/developer-connect/docs/connect-github-enterprise-cloud#link-repos). ## Add repository links to existing connections Once you have established a connection to GitHub Enterprise Cloud, you can link to repositories. You can repeat these steps later to link additional repositories as needed. To create repository links on an existing GitHub Enterprise Cloud connection, select one of the following options: ### Console 1. Open the **Repositories** page in the Google Cloud console. [Open the **Repositories** page](https://console.cloud.google.com/developer-connect/git-repository-links) 2. Click **Link repository**. The **Link Git repositories** pane opens. 3. In the connections list, choose a connection. 4. Click **Continue**. 5. In the repositories list, select the repositories you want to link to. 6. Click **Create**. Developer Connect creates the repository links and displays them in the Google Cloud console. ### gcloud Run the following command: gcloud developer-connect connections git-repository-links create REPO_NAME \ --clone-uri=REPO_URI \ --connection=CONNECTION_NAME \ --location=REGION Replace the following: - REPO_NAME: the name of your repository. - REPO_URI: the link to your GitHub Enterprise Cloud repository. For example, `https://github.com/cloud-build/test-repo.git`. - CONNECTION_NAME: the name of your connection. - REGION: the [region](https://docs.cloud.google.com/developer-connect/docs/locations) for your connection. Developer Connect creates the repository links. To list linked repositories, run the [`developer-connect connections git-repository-links list`](https://docs.cloud.google.com/gcloud/reference/developer-connect/connections/git-repository-links/list) command. If you're setting up Gemini Code Assist, continue the process by following the steps in [Configure and use Gemini Code Assist code customization](https://docs.cloud.google.com/gemini/docs/codeassist/code-customization). ## Configure IP allowlists Developer Connect is compatible with GitHub Enterprise Cloud organizations that use IP allowlists to restrict access to their resources. To configure your GitHub Enterprise Cloud allowlist for use with Developer Connect, complete the following steps. Use the GitHub Enterprise Cloud *organization owner* account to complete these tasks. 1. Sign in to [GitHub Enterprise Cloud](https://github.com/). 2. Follow the instructions in the GitHub Enterprise Cloud documentation to [allow access by GitHub apps](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization#allowing-access-by-github-apps). GitHub Enterprise Cloud adds the Developer Connect GitHub app addresses to your allowlist. You can identify the Developer Connect addresses by their descriptions, which are similar to the following text: `managed by the Developer Connect GitHub app`. 3. Now that the Developer Connect GitHub app can access your GitHub Enterprise Cloud resources, configure your allowlist to use the same IP addresses for OAuth-based interactions between Developer Connect and GitHub Enterprise Cloud. This allows Developer Connect to create links to your Git repositories. 1. Copy all of the Developer Connect GitHub app IP addresses. 2. Follow the instructions in GitHub Enterprise Cloud documentation to [add each address to your allowlist](https://docs.github.com/en/enterprise-cloud@latest/organizations/keeping-your-organization-secure/managing-security-settings-for-your-organization/managing-allowed-ip-addresses-for-your-organization#allowing-access-by-github-apps) as a new entry. When you're finished, you have two allowlist entries for each IP address that Developer Connect uses to communicate with GitHub Enterprise Cloud. The OAuth entries are only used for creating links to repositories. You can delete the OAuth entries from your allowlist when you're done creating links to GitHub Enterprise Cloud repositories. ## Data sharing Content from Google Cloud resources linked to this connection might be transferred to GitHub. This statement applies to all existing and future resources utilizing this connection. To stop sharing information with GitHub, delete Developer Connect connections in the Google Cloud console or gcloud CLI, and [revoke access in GitHub](https://docs.github.com/en/apps/using-github-apps/reviewing-and-revoking-authorization-of-github-apps). ## What's next - [Finish setting up Gemini Code Assist code customization](https://docs.cloud.google.com/gemini/docs/codeassist/code-customization). - [Learn how Gemini Code Assist helps you accelerate software development](https://docs.cloud.google.com/gemini/docs/codeassist/overview). - [Explore other integrations available through Developer Connect.](https://docs.cloud.google.com/developer-connect/docs/overview)
