Service Description: Managed Apache Airflow Environments.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (EnvironmentsClient environmentsClient = EnvironmentsClient.create()) {
   String name = "name3373707";
   Environment response = environmentsClient.getEnvironment(name);
 }

Note: close() needs to be called on the EnvironmentsClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

The surface of this class includes several types of Java methods for each of the API's methods:

A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
A "callable" method. This type of method takes no parameters and returns an immutable API callable object, which can be used to initiate calls to the service.

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of EnvironmentsSettings to create(). For example:

To customize credentials:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 EnvironmentsSettings environmentsSettings =
     EnvironmentsSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 EnvironmentsClient environmentsClient = EnvironmentsClient.create(environmentsSettings);

To customize the endpoint:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 EnvironmentsSettings environmentsSettings =
     EnvironmentsSettings.newBuilder().setEndpoint(myEndpoint).build();
 EnvironmentsClient environmentsClient = EnvironmentsClient.create(environmentsSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 EnvironmentsSettings environmentsSettings = EnvironmentsSettings.newHttpJsonBuilder().build();
 EnvironmentsClient environmentsClient = EnvironmentsClient.create(environmentsSettings);

```
Update an environment.
Sample code:
```
 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (EnvironmentsClient environmentsClient = EnvironmentsClient.create()) {
   String name = "name3373707";
   Environment environment = Environment.newBuilder().build();
   FieldMask updateMask = FieldMask.newBuilder().build();
   Environment response =
       environmentsClient.updateEnvironmentAsync(name, environment, updateMask).get();
 }
 
```
Parameters:

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

environment - A patch environment. Fields specified by the `updateMask` will be copied from the patch environment into the environment under update.
updateMask - 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 argparse, the `updateMask` parameter would include the following two `paths` values: "config.softwareConfig.pypiPackages.scikit-learn" and "config.softwareConfig.pypiPackages.argparse". 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 argparse 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.imageVersion` * Upgrade the version of the environment in-place. Refer to `SoftwareConfig.image_version` for information on how to format the new image version. Additionally, the new image version cannot effect a version downgrade, and must match the current image version's Composer and Airflow major versions. Consult the [Cloud Composer version list](/composer/docs/concepts/versioning/composer-versions) for valid values.
- `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.softwareConfig.cloudDataLineageIntegration` * Configuration for Cloud Data Lineage integration.
- `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-*.*.*.
- `config.maintenanceWindow` * Maintenance window during which Cloud Composer components may be under maintenance.
- `config.workloadsConfig` * The workloads configuration settings for the GKE cluster associated with the Cloud Composer environment. Supported for Cloud Composer environments in versions composer-2.*.*-airflow-*.*.* and newer.
- `config.environmentSize` * The size of the Cloud Composer environment. Supported for Cloud Composer environments in versions composer-2.*.*-airflow-*.*.* and newer.
