Google Cloud Build Operators
============================

The `GoogleCloud Build <https://cloud.google.com/cloud-build/>`__ is a service that executes your builds on Google Cloud
infrastructure. Cloud Build can import source code from Google Cloud Storage,
Cloud Source Repositories, execute a build to your specifications, and produce
artifacts such as Docker containers or Java archives.

Prerequisite Tasks
^^^^^^^^^^^^^^^^^^

.. include::/operators/_partials/prerequisite_tasks.rst

.. _howto/operator:CloudBuildBuild:

Build configuration overview
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In order to trigger a build, it is necessary to pass the build configuration.


.. exampleinclude:: /../../airflow/providers/google/cloud/example_dags/example_cloud_build.py
    :language: python
    :dedent: 0
    :start-after: [START howto_operator_gcp_create_build_from_storage_body]
    :end-before: [END howto_operator_gcp_create_build_from_storage_body]

The source code for the build can come from `Google Cloud Build Storage <https://cloud.google.com/storage/>`__:

.. literalinclude:: /../../tests/providers/google/cloud/operators/test_cloud_build.py
    :language: python
    :dedent: 12
    :start-after: [START howto_operator_gcp_cloud_build_source_gcs_dict]
    :end-before: [END howto_operator_gcp_cloud_build_source_gcs_dict]

It is also possible to specify it using the URL:

.. literalinclude:: /../../tests/providers/google/cloud/operators/test_cloud_build.py
    :language: python
    :dedent: 12
    :start-after: [START howto_operator_gcp_cloud_build_source_gcs_url]
    :end-before: [END howto_operator_gcp_cloud_build_source_gcs_url]

In addition, a build can refer to source stored in `Google Cloud Source Repositories <https://cloud.google.com/source-repositories/docs/>`__.

.. literalinclude:: /../../tests/providers/google/cloud/operators/test_cloud_build.py
    :language: python
    :dedent: 12
    :start-after: [START howto_operator_gcp_cloud_build_source_repo_dict]
    :end-before: [END howto_operator_gcp_cloud_build_source_repo_dict]

It is also possible to specify it using the URL:

.. literalinclude:: /../../tests/providers/google/cloud/operators/test_cloud_build.py
    :language: python
    :dedent: 12
    :start-after: [START howto_operator_gcp_cloud_build_source_repo_url]
    :end-before: [END howto_operator_gcp_cloud_build_source_repo_url]

It is also possible to specify it using a YAML or JSON format.

.. exampleinclude:: /../../airflow/providers/google/cloud/example_dags/example_cloud_build.py
    :language: python
    :dedent: 0
    :start-after: [START howto_operator_gcp_create_build_from_yaml_body]
    :end-before: [END howto_operator_gcp_create_build_from_yaml_body]

Read `Build Configuration Overview <https://cloud.google.com/cloud-build/docs/build-config>`__ to understand all the fields you can include in a build config file.


.. _howto/operator:CloudBuildCreateBuildOperator:

Trigger a build
^^^^^^^^^^^^^^^

Trigger a build is performed with the
:class:`~airflow.providers.google.cloud.operators.cloud_build.CloudBuildCreateBuildOperator` operator.

.. exampleinclude:: /../../airflow/providers/google/cloud/example_dags/example_cloud_build.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_create_build_from_storage]
    :end-before: [END howto_operator_create_build_from_storage]

You can use :ref:`Jinja templating <jinja-templating>` with
:template-fields:`airflow.providers.google.cloud.operators.cloud_build.CloudBuildCreateBuildOperator`
parameters which allows you to dynamically determine values. The result is saved to :ref:`XCom <concepts:xcom>`, which allows it
to be used by other operators.

.. exampleinclude:: /../../airflow/providers/google/cloud/example_dags/example_cloud_build.py
    :language: python
    :dedent: 4
    :start-after: [START howto_operator_create_build_from_storage_result]
    :end-before: [END howto_operator_create_build_from_storage_result]
