Sample schedules - Instance Scheduler on AWS

Sample schedules

Instance Scheduler on AWS allows you to automatically start and stop Amazon Elastic Compute Cloud (Amazon EC2) and Amazon Relational Database Service (Amazon RDS) instances. The following section provides some example schedules that can be adapted to many common use cases.

Standard 9-5 working hours

This schedule shows how to run instances on weekdays from 9 AM to 5 PM in London.

Periods

This period will start instances at 9 AM and stop instances at 5 PM on weekdays (Mon-Fri).

Field Type Value
begintime String 09:00
endtime String 16:59
name String weekdays-9-5
weekdays StringSet mon-fri

Schedule

The schedule name provides the tag value that must be applied to instances and the timezone that will be used.

Field Type Value
name String london-working-hours
periods StringSet weekdays-9-5
timezone String Europe/London

Instance tag

To apply this schedule to instances, you must add the Schedule=london-working-hours tag to the instances. If you change the default tag name in the AWS CloudFormation Instance Scheduler tag name parameter, your tag will be different. For example, if you entered Sked as your tag name, your tag will be Sked=london-working-hours. For more information, refer to Tag your resources in the Amazon Elastic Compute Cloud User Guide.

Scheduler CLI

To configure the above schedule using the Instance Scheduler CLI, use the following commands:

scheduler-cli create-period --stack <stackname> --name weekdays-9-5 --weekdays mon-fri --begintime 9:00 --endtime 16:59 scheduler-cli create-schedule --stack <stackname> --name london-working-hours --periods weekdays-9-5 -–timezone Europe/London Europe/London

Custom resource

The following CloudFormation template will create the above schedule using the schedule custom resource.

To deploy this template, you will need to provide the ServiceInstanceScheduleServiceToken ARN that can be found in the AWS CloudFormation console by selecting the previously deployed Instance Scheduler Hub Stack and then select Outputs.

AWSTemplateFormatVersion: 2010-09-09 Parameters: ServiceInstanceScheduleServiceTokenARN: Type: String Description: (Required) service token arn taken from InstanceScheduler outputs Metadata: 'AWS::CloudFormation::Designer': {} Resources: LondonWorkingWeek: Type: 'Custom::ServiceInstanceSchedule' Properties: NoStackPrefix: 'True' Name: london-working-hours Description: run instances from 9am to 5pm in London on weekdays ServiceToken: !Ref ServiceInstanceScheduleServiceTokenARN Timezone: Europe/London Periods: - Description: 9am to 5pm on weekdays BeginTime: '09:00' EndTime: '16:59' WeekDays: mon-fri

Stop instances after 5 PM

Instances can be started freely at any time during the day and this schedule will ensure that a stop command is automatically sent to them at 5 PM ET every day.

Periods

This period will stop instances at 5 PM every day.

Field Type Value
endtime String 16:59
name String stop-at-5

Schedule

The schedule name provides the tag value that must be applied to instances and the timezone that will be used.

Field Value
name String stop-at-5-new-york
periods StringSet stop-at-5
timezone String America/New York

Instance tag

To apply this schedule to instances, you must add the Schedule=stop-at-5-new-york tag to the instances. If you changed the default tag name in the AWS CloudFormation Instance Scheduler tag name parameter, your tag will be different. For example, if you entered Sked as your tag name, your tag will be Sked=stop-at-5-new-york . For more information, refer to Tag your resources in the Amazon Elastic Compute Cloud User Guide.

Scheduler CLI

To configure the above schedule using the Instance Scheduler CLI, use the following commands:

scheduler-cli create-period --stack <stackname> --name stop-at-5 --endtime 16:59 scheduler-cli create-schedule --stack <stackname> --name stop-at-5-new-york --periods stop-at-5 -–timezone America/New_York

Custom resource

The following CloudFormation template will create the above schedule using the schedule custom resource.

To deploy this template, you will need to provide the ServiceInstanceScheduleServiceToken ARN that can be found in the AWS CloudFormation console by clicking on the previously deployed Instance Scheduler Hub Stack and selecting Outputs.

AWSTemplateFormatVersion: 2010-09-09 Parameters: ServiceInstanceScheduleServiceTokenARN: Type: String Description: (Required) service token arn taken from InstanceScheduler outputs Metadata: 'AWS::CloudFormation::Designer': {} Resources: StopAfter5: Type: 'Custom::ServiceInstanceSchedule' Properties: NoStackPrefix: 'True' Name: stop-at-5-new-york Description: stop instances at 5pm ET every day ServiceToken: !Ref ServiceInstanceScheduleServiceTokenARN Timezone: America/New_York Periods: - Description: stop at 5pm EndTime: '16:59'

Stop instances over the weekend

This schedule shows how to run instances from Monday 9 AM ET to Friday 5 PM ET. Since Monday and Friday are not full days, this schedule includes three periods to accommodate: Monday, Tuesday-Thursday, and Friday.

Periods

The first period starts tagged instances at 9 AM Monday and stops at midnight. This period includes the following fields and values.

Field Type Value
begintime String 09:00
endtime String 23:59
name String mon-start-9am
weekdays StringSet mon

The second period runs tagged instances all day Tuesday through Thursday. This period includes the following fields and values.

Field Value
name String tue-thu-full-day
weekdays StringSet tue-thu

The third period stops tagged instances at 5 PM on Friday. This period includes the following fields and values.

Field Value
begintime String 00:00
endtime String 16:59
name String fri-stop-5pm
weekdays StringSet fri

Schedule

The schedule combines the three periods into the schedule for tagged instances. The schedule includes the following fields and values.

Field Value
name String mon-9am-fri-5pm
periods StringSet mon-start-9am,tue-thu-full-day,fri-stop-5pm
timezone String America/New_York

Instance tag

To apply this schedule to instances, you must add the Schedule=mon-9am-fri-5pm tag to the instances. Note that if you changed the default tag name in the AWS CloudFormation Instance Scheduler tag name parameter, your tag will be different. For example, if you entered Sked as your tag name, your tag will be Sked=mon-9am-fri-5pm. For more information, refer to Tag your resources in the Amazon Elastic Compute Cloud User Guide.
