Start a pipeline on a schedule

Open the Amazon EventBridge console at https://console.aws.amazon.com/events/.

In the navigation pane, choose Rules.

Choose Create rule, and then under Rule detail, choose Schedule.

Set up the schedule using a fixed rate or expression. For information, see Schedule Expression for Rules.

In Targets, choose CodePipeline.

Enter the pipeline ARN for the pipeline execution for this schedule.

Choose one of the following to create or specify an IAM service role that gives EventBridge permissions to invoke the target associated with your EventBridge rule (in this case, the target is CodePipeline).

Choose Configure details.

On the Configure rule details page, enter a name and description for the rule, and then choose State to enable the rule.

If you're satisfied with the rule, choose Create rule.

Call the put-rule command and include the --name and --schedule-expression parameters.

Examples:

The following sample command uses --schedule-expression to create a rule called MyRule2 that filters EventBridge on a schedule.

aws events put-rule --schedule-expression 'cron(15 10 ? * 6L 2002-2005)' --name MyRule2

To add CodePipeline as a target, call the put-targets command and include the following parameters:

The following sample command specifies that for the rule called MyCodeCommitRepoRule, the target Id is composed of the number one, indicating that in a list of targets for the rule, this is target 1. The sample command also specifies an example ARN for the pipeline. The pipeline starts when something changes in the repository.

aws events put-targets --rule MyCodeCommitRepoRule --targets Id=1,Arn=arn:aws:codepipeline:us-west-2:80398EXAMPLE:TestPipeline

Grant permissions for EventBridge to use CodePipeline to invoke the rule. For more information, see Using resource-based policies for Amazon EventBridge.

1. Use the following sample to create the trust policy to allow EventBridge to assume the service role. Name it trustpolicyforEB.json.

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Principal": {
                   "Service": "events.amazonaws.com"
               },
               "Action": "sts:AssumeRole"
           }
       ]
   }

2. Use the following command to create the Role-for-MyRule role and attach the trust policy.

   aws iam create-role --role-name Role-for-MyRule --assume-role-policy-document file://trustpolicyforEB.json

3. Create the permissions policy JSON as shown in this sample for the pipeline named MyFirstPipeline. Name the permissions policy permissionspolicyforEB.json.

   {
       "Version": "2012-10-17",
       "Statement": [
           {
               "Effect": "Allow",
               "Action": [
                   "codepipeline:StartPipelineExecution"
               ],
               "Resource": [
                   "arn:aws:codepipeline:us-west-2:80398EXAMPLE:MyFirstPipeline"
               ]
           }
       ]
   }
   

4. Use the following command to attach the new CodePipeline-Permissions-Policy-for-EB permissions policy to the Role-for-MyRule role you created.

   aws iam put-role-policy --role-name Role-for-MyRule --policy-name CodePipeline-Permissions-Policy-For-EB --policy-document file://permissionspolicyforCWE.json
