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

      "config.softwareConfig.pypiPackages" mask. * labels * Replace all
      environment labels. If a replacement labels map is not included in

      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. *
      config.webServerNetworkAccessControl * Replace the environment's current
      WebServerNetworkAccessControl. *

      preserving other properties. To delete the property override, include it
      in `updateMask` and omit its mapping in

      set only if the environment is VPC-native. The default value is 32.
      Values of this field will be propagated both to the `default-pool` node
