AppEngineHttpTarget

App Engine target. The job will be pushed to a job handler by means of an HTTP request via an http_method such as HTTP POST, HTTP GET, etc. The job is acknowledged by means of an HTTP response code in the range [200 - 299]. Error 503 is considered an App Engine system error instead of an application error. Requests returning error 503 will be retried regardless of retry configuration and not counted against retry counts. Any other response code, or a failure to receive a response before the deadline, constitutes a failed attempt.

Fields
http_method

HttpMethod

The HTTP method to use for the request. PATCH and OPTIONS are not permitted.

app_engine_routing

AppEngineRouting

App Engine Routing setting for the job.

relative_uri

string

The relative URI.

The relative URL must begin with "/" and must be a valid HTTP relative URL. It can contain a path, query string arguments, and # fragments. If the relative URL is empty, then the root path "/" will be used. No spaces are allowed, and the maximum length allowed is 2083 characters.

headers

map<string, string>

HTTP request headers.

This map contains the header field names and values. Headers can be set when the job is created.

Cloud Scheduler sets some headers to default values:

  • User-Agent: By default, this header is "AppEngine-Google; (+http://code.google.com/appengine)". This header can be modified, but Cloud Scheduler will append "AppEngine-Google; (+http://code.google.com/appengine)" to the modified User-Agent.
  • X-CloudScheduler: This header will be set to true.

If the job has an body, Cloud Scheduler sets the following headers:

  • Content-Type: By default, the Content-Type header is set to "application/octet-stream". The default can be overridden by explictly setting Content-Type to a particular media type when the job is created. For example, Content-Type can be set to "application/json".
  • Content-Length: This is computed by Cloud Scheduler. This value is output only. It cannot be changed.

The headers below are output only. They cannot be set or overridden:

  • X-Google-*: For Google internal use only.
  • X-AppEngine-*: For Google internal use only.

In addition, some App Engine headers, which contain job-specific information, are also be sent to the job handler.

body

bytes

Body.

HTTP request body. A request body is allowed only if the HTTP method is POST or PUT. It will result in invalid argument error to set a body on a job with an incompatible HttpMethod.

AppEngineRouting

App Engine Routing.

For more information about services, versions, and instances see An Overview of App Engine, Microservices Architecture on Google App Engine, App Engine Standard request routing, and App Engine Flex request routing.

Fields
service

string

App service.

By default, the job is sent to the service which is the default service when the job is attempted.

version

string

App version.

By default, the job is sent to the version which is the default version when the job is attempted.

instance

string

App instance.

By default, the job is sent to an instance which is available when the job is attempted.

Requests can only be sent to a specific instance if manual scaling is used in App Engine Standard. App Engine Flex does not support instances. For more information, see App Engine Standard request routing and App Engine Flex request routing.

host

string

Output only. The host that the job is sent to.

For more information about how App Engine requests are routed, see here.

The host is constructed as:

  • host = [application_domain_name]
    | [service] + '.' + [application_domain_name]
    | [version] + '.' + [application_domain_name]
    | [version_dot_service]+ '.' + [application_domain_name]
    | [instance] + '.' + [application_domain_name]
    | [instance_dot_service] + '.' + [application_domain_name]
    | [instance_dot_version] + '.' + [application_domain_name]
    | [instance_dot_version_dot_service] + '.' + [application_domain_name]

  • application_domain_name = The domain name of the app, for example .appspot.com, which is associated with the job's project ID.

  • service = service

  • version = version

  • version_dot_service = version + '.' + service

  • instance = instance

  • instance_dot_service = instance + '.' + service

  • instance_dot_version = instance + '.' + version

  • instance_dot_version_dot_service = instance + '.' + version + '.' + service

If service is empty, then the job will be sent to the service which is the default service when the job is attempted.

If version is empty, then the job will be sent to the version which is the default version when the job is attempted.

If instance is empty, then the job will be sent to an instance which is available when the job is attempted.

If service, version, or instance is invalid, then the job will be sent to the default version of the default service when the job is attempted.

schedule

string

Required, except when used with UpdateJob.

Describes the schedule on which the job will be executed.

The schedule can be either of the following types:

As a general rule, execution n + 1 of a job will not begin until execution n has finished. Cloud Scheduler will never allow two simultaneously outstanding executions. For example, this implies that if the n+1th execution is scheduled to run at 16:00 but the nth execution takes until 16:15, the n+1th execution will not start until 16:15. A scheduled start time will be delayed if the previous execution has not ended when its scheduled time occurs.

If retry_count > 0 and a job attempt fails, the job will be tried a total of retry_count times, with exponential backoff, until the next scheduled start time.

time_zone

string

Specifies the time zone to be used in interpreting schedule. The value of this field must be a time zone name from the tz database.

Note that some time zones include a provision for daylight savings time. The rules for daylight saving time are determined by the chosen tz. For UTC use the string "utc". If a time zone is not specified, the default will be in UTC (also known as GMT).

The job name. For example: projects/PROJECT_ID/locations/LOCATION_ID/jobs/JOB_ID.

Authorization requires the following Google IAM permission on the specified resource name:

  • cloudscheduler.jobs.enable

RetryConfig

Settings that determine the retry behavior.

By default, if a job does not complete successfully (meaning that an acknowledgement is not received from the handler, then it will be retried with exponential backoff according to the settings in RetryConfig.

Fields
retry_count

int32

The number of attempts that the system will make to run a job using the exponential backoff procedure described by max_doublings.

The default value of retry_count is zero.

If retry_count is zero, a job attempt will not be retried if it fails. Instead the Cloud Scheduler system will wait for the next scheduled execution time.

If retry_count is set to a non-zero number then Cloud Scheduler will retry failed attempts, using exponential backoff, retry_count times, or until the next scheduled execution time, whichever comes first.

Values greater than 5 and negative values are not allowed.

max_retry_duration

Duration

The time limit for retrying a failed job, measured from time when an execution was first attempted. If specified with retry_count, the job will be retried until both limits are reached.

The default value for max_retry_duration is zero, which means retry duration is unlimited.

min_backoff_duration

Duration

The minimum amount of time to wait before retrying a job after it fails.

The default value of this field is 5 seconds.

max_backoff_duration

Duration

The maximum amount of time to wait before retrying a job after it fails.

The default value of this field is 1 hour.

max_doublings

int32

The time between retries will double max_doublings times.

A job's retry interval starts at min_backoff_duration, then doubles max_doublings times, then increases linearly, and finally retries retries at intervals of max_backoff_duration up to retry_count times.

For example, if min_backoff_duration is 10s, max_backoff_duration is 300s, and max_doublings is 3, then the a job will first be retried in 10s. The retry interval will double three times, and then increase linearly by 2^3 * 10s. Finally, the job will retry at intervals of max_backoff_duration until the job has been attempted retry_count times. Thus, the requests will retry at 10s, 20s, 40s, 80s, 160s, 240s, 300s, 300s, ....

The default value of this field is 5.
