Connect to a Bitbucket Data Center host

This page explains how to connect a Bitbucket Data Center host to Cloud Build.

Before you begin

  • Enable the Cloud Build, Secret Manager, and Compute Engine APIs.

    Enable the APIs

  • Have your source code ready in a Bitbucket Data Center repository.
  • Have either a Dockerfile or a Cloud Build config file in your Bitbucket Data Center source repository.
  • If you have not installed a Bitbucket Data Center instance, see Install Bitbucket Data Center for instructions.

  • To use gcloud commands on this page, install the Google Cloud CLI.

Connect to a Bitbucket Data Center host

Console

To connect your Bitbucket Data Center 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 Data Center from the drop-down menu.

    You will see the Connect host panel.

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

    1. Region: Select the region for your connection.

    2. Name: Enter a name for your connection.

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

    4. Google Cloud API key: Enter the API key used to authenticate your credentials.

    5. 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 you leave this section blank, Google Cloud uses a certificate from the default set of certificates.

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

    7. Read access token: Enter your Bitbucket Data Center account personal access token with read permissions.

    8. Admin access token: Enter your Bitbucket Data Center account personal access token with admin permissions on projects and repositories.

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

      1. Public internet: Select this option if your instance is accessible using 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 Data Center 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 Data Center 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_DATA_CENTER_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_DATA_CENTER_CONFIG_NAME is the name of your Bitbucket Data Center configuration.
  • USERNAME is your Bitbucket Data Center username.
  • HOST_URI is the host URI of your Bitbucket Data Center 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.
