# Create a client using a custom configuration
client = ::Google::Cloud::AppEngine::V1::Instances::Rest::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Instances client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Instances Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#debug_instance(request, options = nil) ⇒ ::Gapic::Operation #debug_instance(name: nil, ssh_key: nil) ⇒ ::Gapic::Operation

Enables debugging on a VM instance. This allows you to use the SSH command to connect to the virtual machine where the instance lives. While in "debug mode", the instance continues to serve live traffic. You should delete the instance when you are done debugging and then allow the system to take over and determine if another instance should be started.

Only applicable for instances in App Engine flexible environment.

Examples:

Basic example

require "google/cloud/app_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AppEngine::V1::Instances::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AppEngine::V1::DebugInstanceRequest.new

# Call the debug_instance method.
result = client.debug_instance request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #debug_instance(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to debug_instance via a request object, either of type DebugInstanceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AppEngine::V1::DebugInstanceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #debug_instance(name: nil, ssh_key: nil) ⇒ ::Gapic::Operation

    Pass arguments to debug_instance via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Name of the resource requested. Example: apps/myapp/services/default/versions/v1/instances/instance-1.

    • ssh_key (::String) (defaults to: nil) —

      Public SSH key to add to the instance. Examples:

      • [USERNAME]:ssh-rsa [KEY_VALUE] [USERNAME]
      • [USERNAME]:ssh-rsa [KEY_VALUE] google-ssh {"userName":"[USERNAME]","expireOn":"[EXPIRE_TIME]"}

      For more information, see Adding and Removing SSH Keys.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

  • result (::Gapic::Operation)
  • operation (::Gapic::Rest::TransportOperation)

Returns:

  • (::Gapic::Operation)

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

end

#delete_instance(request, options = nil) ⇒ ::Gapic::Operation #delete_instance(name: nil) ⇒ ::Gapic::Operation

Stops a running instance.

The instance might be automatically recreated based on the scaling settings of the version. For more information, see "How Instances are Managed" (standard environment | flexible environment).

To ensure that instances are not re-created and avoid getting billed, you can stop all instances within the target version by changing the serving status of the version to STOPPED with the apps.services.versions.patch method.

Examples:

Basic example

require "google/cloud/app_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AppEngine::V1::Instances::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AppEngine::V1::DeleteInstanceRequest.new

# Call the delete_instance method.
result = client.delete_instance request

# The returned object is of type Gapic::Operation. You can use it to
# check the status of an operation, cancel it, or wait for results.
# Here is how to wait for a response.
result.wait_until_done! timeout: 60
if result.response?
  p result.response
else
  puts "No response received."
end

Overloads:

  • #delete_instance(request, options = nil) ⇒ ::Gapic::Operation

    Pass arguments to delete_instance via a request object, either of type DeleteInstanceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AppEngine::V1::DeleteInstanceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.
