Class EnvironmentsClient (2.11.0)

Managed Apache Airflow Environments.

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Returns
Type Description
StreamRange< google::cloud::orchestration::airflow::service::v1::Environment >

a StreamRange to iterate of the results. See the documentation of this type for details. In brief, this class has begin() and end() member functions returning a iterator class meeting the input iterator requirements. The value type for this iterator is a StatusOr as the iteration may fail even after some values are retrieved successfully, for example, if there is a network disconnect. An empty set of results does not indicate an error, it indicates that there are no resources meeting the request criteria. On a successful iteration the StatusOr<T> contains elements of type google.cloud.orchestration.airflow.service.v1.Environment, or rather, the C++ class generated by Protobuf from that type. Please consult the Protobuf documentation for details on the Protobuf mapping rules.

UpdateEnvironment(std::string const &, google::cloud::orchestration::airflow::service::v1::Environment const &, google::protobuf::FieldMask const &, Options)

Update an environment.

Parameters
Name Description
name std::string const &

The relative resource name of the environment to update, in the form: "projects/{projectId}/locations/{locationId}/environments/{environmentId}"

environment google::cloud::orchestration::airflow::service::v1::Environment const &

A patch environment. Fields specified by the updateMask will be copied from the patch environment into the environment under update.

update_mask google::protobuf::FieldMask const &

Required. A comma-separated list of paths, relative to Environment, of fields to update. For example, to set the version of scikit-learn to install in the environment to 0.19.0 and to remove an existing installation of numpy, the updateMask parameter would include the following two paths values: "config.softwareConfig.pypiPackages.scikit-learn" and "config.softwareConfig.pypiPackages.numpy". The included patch environment would specify the scikit-learn version as follows:
{ "config":{ "softwareConfig":{ "pypiPackages":{ "scikit-learn":"==0.19.0" } } } }
Note that in the above example, any existing PyPI packages other than scikit-learn and numpy will be unaffected.
Only one update type may be included in a single request's updateMask. For example, one cannot update both the PyPI packages and labels in the same request. However, it is possible to update multiple members of a map field simultaneously in the same request. For example, to set the labels "label1" and "label2" while clearing "label3" (assuming it already exists), one can provide the paths "labels.label1", "labels.label2", and "labels.label3" and populate the patch environment as follows:
{ "labels":{ "label1":"new-label1-value" "label2":"new-label2-value" } }
Note that in the above example, any existing labels that are not included in the updateMask will be unaffected.
It is also possible to replace an entire map field by providing the map field's path in the updateMask. The new value of the field will be that which is provided in the patch environment. For example, to delete all pre-existing user-specified PyPI packages and install botocore at version 1.7.14, the updateMask would contain the path "config.softwareConfig.pypiPackages", and the patch environment would be the following:
{ "config":{ "softwareConfig":{ "pypiPackages":{ "botocore":"==1.7.14" } } } }
Note: Only the following fields can be updated:

  • config.softwareConfig.pypiPackages
    • Replace all custom custom PyPI packages. If a replacement package map is not included in environment, all custom PyPI packages are cleared. It is an error to provide both this mask and a mask specifying an individual package.
  • config.softwareConfig.pypiPackages.packagename
    • Update the custom PyPI package packagename, preserving other packages. To delete the package, include it in updateMask, and omit the mapping for it in environment.config.softwareConfig.pypiPackages. It is an error to provide both a mask of this form and the config.softwareConfig.pypiPackages mask.
  • labels
    • Replace all environment labels. If a replacement labels map is not included in environment, all labels are cleared. It is an error to provide both this mask and a mask specifying one or more individual labels.
  • labels.labelName
    • Set the label named labelName, while preserving other labels. To delete the label, include it in updateMask and omit its mapping in environment.labels. It is an error to provide both a mask of this form and the labels mask.
  • config.nodeCount
    • Horizontally scale the number of nodes in the environment. An integer greater than or equal to 3 must be provided in the config.nodeCount field. Supported for Cloud Composer environments in versions composer-1..-airflow-..*.
  • config.webServerNetworkAccessControl
    • Replace the environment's current WebServerNetworkAccessControl.
  • config.softwareConfig.airflowConfigOverrides
    • Replace all Apache Airflow config overrides. If a replacement config overrides map is not included in environment, all config overrides are cleared. It is an error to provide both this mask and a mask specifying one or more individual config overrides.
  • config.softwareConfig.airflowConfigOverrides.section-name
    • Override the Apache Airflow config property name in the section named section, preserving other properties. To delete the property override, include it in updateMask and omit its mapping in environment.config.softwareConfig.airflowConfigOverrides. It is an error to provide both a mask of this form and the config.softwareConfig.airflowConfigOverrides mask.
  • config.softwareConfig.envVariables
    • Replace all environment variables. If a replacement environment variable map is not included in environment, all custom environment variables are cleared.
  • config.softwareConfig.schedulerCount
    • Horizontally scale the number of schedulers in Airflow. A positive integer not greater than the number of nodes must be provided in the config.softwareConfig.schedulerCount field. Supported for Cloud Composer environments in versions composer-1..-airflow-2...
  • config.databaseConfig.machineType
    • Cloud SQL machine type used by Airflow database. It has to be one of: db-n1-standard-2, db-n1-standard-4, db-n1-standard-8 or db-n1-standard-16. Supported for Cloud Composer environments in versions composer-1..-airflow-..*.
  • config.webServerConfig.machineType
    • Machine type on which Airflow web server is running. It has to be one of: composer-n1-webserver-2, composer-n1-webserver-4 or composer-n1-webserver-8. Supported for Cloud Composer environments in versions composer-1..-airflow-..*.
