Connect to a Bitbucket Server host

Console

To connect your Bitbucket Server host to Cloud Build using the Google Cloud console:

1. Open the Repositories page in the Google Cloud console:

   Open the Repositories page

2. At the top of the page, select the 1st gen tab.

3. Click Connect Host.

4. Select Bitbucket Server from the drop-down menu.

   You will see the Connect host panel.

   Enter the following information to connect your Bitbucket Server instance to Cloud Build:

   • Region: Select the region for your connection.

   • Name: Enter a name for your connection.

   1. Host url: Your host URL of your Bitbucket Server instance. For example, https://bbs.example-test.com:7990.

   2. Google Cloud API key: Your API key used to authenticate your credentials.

   3. CA Certificate: Your self-signed certificate. Your certificate must not exceed 10 KB in size and should be in PEM format (.pem, .cer,or .crt). If this section is left blank, a default set of certificates is used in place.

   4. Username: Your Bitbucket Server account username. This account should have admin access to the repositories that you want to connect with Cloud Build.

   5. Read access token: Your Bitbucket Server account personal access token with read permissions.

   6. Admin access token: Your Bitbucket Server account personal access token with admin permissions on projects and repositories.

   7. Under Network type, select one of the following options:

      1. Public internet: Select this option if your instance is accessible via the public internet.

      2. Private network: Select this option if your instance is hosted on a private network.

         1. Project: Select your Google Cloud project ID.

         2. Network: Select your network from the drop-down menu. If you have not created a network, see Create and manage VPC networks to learn how to create a network.

         3. IP range: Enter the internal IP range that VMs can be assigned within a peered network's allocated range.

            You can specify the range using the Classless Inter-Domain Routing (CIDR) routing notation in the format STARTING_IP/SUBNET_PREFIX_SIZE. For example, 192.0.2.0/24 has a prefix length of 24. The first 24 bits of the IP range are used as the subnet mask (192.0.2.0) while the possible hosts addresses range from 192.0.2.0 to 192.0.2.255.

            The value of your prefix length must not exceed /29. If no value is specified for the range, a default value of /24 is automatically assigned. If no value is specified for the prefix length, IP addresses are automatically assigned within the peered VPC network. If no value is specified for the IP address, the IP address is automatically assigned a range within the peered VPC network.

5. Click Connect Host.

   If your Bitbucket Server instance is on a peered network, connecting your host may take several minutes to complete.

   You will be redirected to the Connect Repository panel.

   After creating a host connection, your personal access tokens and webhook secret will be securely stored in Secret Manager. You can view and manage your secrets on the Secret Manager page.

gcloud

To connect your Bitbucket Server host to Cloud Build using gcloud commands, you must run the gcloud alpha builds enterprise-config bitbucketserver create command in your terminal. Unlike connecting your host using the Google Cloud console, you'll need to manually store your personal access tokens and webhook secret in Secret Manager before running the following command:

gcloud alpha builds enterprise-config bitbucketserver create
    --name=BITBUCKET_SERVER_CONFIG_NAME \
    --user-name=USERNAME \
    --host-uri=HOST_URI \
    --admin-access-token-secret-version=ADMIN_ACCESS_TOKEN_SECRET_VERSION \
    --read-access-token-secret-version=READ_ACCESS_TOKEN_SECRET_VERSION \
    --webhook-secret-secret-version=WEBHOOK_SECRET_SECRET_VERSION \
    --api-key=API_KEY \
    --peered-network=PEERED_NETWORK \
    --peered-network-ip-range=PEERED_NETWORK_IP_RANGE \
    --ssl-ca-file=SSL_CA_FILE

Where:

• BITBUCKET_SERVER_CONFIG_NAME is the name of your Bitbucket Server configuration.
• USERNAME is your Bitbucket Server username.
• HOST_URI is the host URI of your Bitbucket Server instance.
• ADMIN_ACCESS_TOKEN_SECRET_VERSION is the resource name of your admin access token stored in Secret Manager. The expected format for secrets stored in Secret Manager is projects/${PROJECT_ID}/secrets/${SECRET_NAME}/versions/${VERSION_NUMBER}. You can specify latest as your version to use the latest version of your secret. This applies to each resource stored in Secret Manager.

• READ_ACCESS_TOKEN_SECRET_VERSION is the resource name of your read access token stored in Secret Manager.
• WEBHOOK_SECRET_SECRET_VERSION is the resource name of your of your webhook secret stored in Secret Manager.
• API_KEY is the Google Cloud API key.

• [Optional] PEERED_NETWORK is the VPC network to connect to for your Bitbucket Server instances on-premises. To learn more, see Build repositories from Bitbucket Server in a private network.

• [Optional] PEERED_NETWORK_IP_RANGE is the internal IP range that VMs can be assigned to within a peered network's allocated range.

• SSL_CA_FILE is the path to a local file that contains your SSL certificate to use for requests to Bitbucket Server. The certificate should be in PEM format.

API

To connect your Bitbucket Server host to Cloud Build using the API, use the following JSON template. Unlike connecting your host using the Google Cloud console, you need to manually store your personal access tokens and webhook secret in Secret Manager before calling the API:

  {
      "hostUri": "HOST_URI",
      "username": "USERNAME",
      "apiKey": "API_KEY",
      "secrets": {
        "adminAccessTokenVersionName": "ADMIN_ACCESS_TOKEN_SECRET_VERSION",
        "readAccessTokenVersionName": "READ_ACCESS_TOKEN_SECRET_VERSION",
        "webhookSecretVersionName": "WEBHOOK_SECRET_SECRET_VERSION",
      },
      "peeredNetwork": "PEERED_NETWORK",
      "peeredNetworkIpRange": "PEERED_NETWORK_IP_RANGE",
      "sslCa": "SSL_CERTIFICATE"
  }
