Tutorial: Create a simple pipeline (S3 bucket) - AWS CodePipeline

Tutorial: Create a simple pipeline (S3 bucket)

The easiest way to create a pipeline is to use the Create pipeline wizard in the AWS CodePipeline console.

In this tutorial, you create a two-stage pipeline that uses a versioned S3 bucket and CodeDeploy to release a sample application.

Note

When Amazon S3 is the source provider for your pipeline, you may zip your source file or files into a single .zip and upload the .zip to your source bucket. You may also upload a single unzipped file; however, downstream actions that expect a .zip file will fail.

After you create this simple pipeline, you add another stage and then disable and enable the transition between stages.

Before you begin, you should complete the prerequisites in Getting started with CodePipeline.

Step 1: Create an S3 bucket for your application

You can store your source files or applications in any versioned location. In this tutorial, you create an S3 bucket for the sample applications and enable versioning on that bucket. After you have enabled versioning, you copy the sample applications to that bucket.

To create an S3 bucket

  1. Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/.

  2. Choose Create bucket.

  3. In Bucket name, enter a name for your bucket (for example, awscodepipeline-demobucket-example-date).

    Note

    Because all bucket names in Amazon S3 must be unique, use one of your own, not the name shown in the example. You can change the example name just by adding the date to it. Make a note of this name because you need it for the rest of this tutorial.

    In Region, choose the Region where you intend to create your pipeline, such as US West (Oregon), and then choose Create bucket.

  4. After the bucket is created, a success banner displays. Choose Go to bucket details.

  5. On the Properties tab, choose Versioning. Choose Enable versioning, and then choose Save.

    When versioning is enabled, Amazon S3 saves every version of every object in the bucket.

  6. On the Permissions tab, leave the defaults. For more information about S3 bucket and object permissions, see Specifying Permissions in a Policy.

  7. Next, download a sample and save it into a folder or directory on your local computer.

    1. Choose one of the following. Choose SampleApp_Windows.zip if you want to follow the steps in this tutorial for Windows Server instances.

      • If you want to deploy to Amazon Linux instances using CodeDeploy, download the sample application here: SampleApp_Linux.zip.

      • If you want to deploy to Windows Server instances using CodeDeploy, download the sample application here: SampleApp_Windows.zip.

    2. Download the compressed (zipped) file. Do not unzip the file.

  8. In the Amazon S3 console, for your bucket, upload the file:

    1. Choose Upload.

    2. Drag and drop the file or choose Add files and browse for the file.

    3. Choose Upload.

Step 2: Create Amazon EC2 Windows instances and install the CodeDeploy agent

Note

This tutorial provides sample steps for creating Amazon EC2 Windows instances. For sample steps to create Amazon EC2 Linux instances, see Step 3: Create an EC2 Linux instance and install the CodeDeploy agent. When prompted for the number of instances to create, specify 2 instances.

In this step, you create the Windows Server Amazon EC2 instances to which you will deploy a sample application. As part of this process, you install the CodeDeploy agent on the instances. The CodeDeploy agent is a software package that enables an instance to be used in CodeDeploy deployments.

To create an instance role

  1. Open the IAM console at https://console.aws.amazon.com/iam/).

  2. From the console dashboard, choose Roles.

  3. Choose Create role.

  4. Under Select type of trusted entity, select AWS service. Under Choose a use case, select EC2, and then choose Next: Permissions.

  5. Search for and select the policy named AmazonEC2RoleforAWSCodeDeploy, and then choose Next: Tags.

  6. Choose Next: Review. Enter a name for the role (for example, EC2InstanceRole).

    Note

    Make a note of your role name for the next step. You choose this role when you are creating your instance.

    Choose Create role.

To launch instances

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. From the console dashboard, choose Launch instance, and select Launch instance from the options that pop up.

  3. On the Step 1: Choose an Amazon Machine Image (AMI) page, locate the Microsoft Windows Server 2019 Base option, and then choose Select. (This AMI is labeled "Free tier eligible" and can be found at the top of the list.)

  4. On the Step 2: Choose an Instance Type page, choose the free tier eligible t2.micro type as the hardware configuration for your instance, and then choose Next: Configure Instance Details.

  5. On the Step 3: Configure Instance Details page, do the following:

    • In Number of instances, enter 2.

    • In Auto-assign Public IP, choose Enable.

    • In IAM role, choose the IAM role you created in the previous procedure (for example, EC2InstanceRole).

    • Expand Advanced Details, and in User data, with As text selected, enter the following:

      <powershell> New-Item -Path c:\temp -ItemType "directory" -Force powershell.exe -Command Read-S3Object -BucketName bucket-name/latest -Key codedeploy-agent.msi -File c:\temp\codedeploy-agent.msi Start-Process -Wait -FilePath c:\temp\codedeploy-agent.msi -WindowStyle Hidden </powershell>

      bucket-name is the name of the S3 bucket that contains the CodeDeploy Resource Kit files for your Region. For example, for the US West (Oregon) Region, replace bucket-name with aws-codedeploy-us-west-2. For a list of bucket names, see Resource Kit Bucket Names by Region.

      This code installs the CodeDeploy agent on your instance as it is created. This script is written for Windows instances only.

    • Leave the rest of the items on the Step 3: Configure Instance Details page unchanged. Choose Next: Add Storage.

  6. Leave the Step 4: Add Storage page unchanged, and then choose Next: Add Tags.

  7. On the Add Tags page, choose Add Tag. Enter Name in the Key field, enter MyCodePipelineDemo in the Value field, and then choose Next: Configure Security Group.

    Important

    The Key and Value boxes are case sensitive.

  8. On the Configure Security Group page, allow port 80 communication so you can access the public instance endpoint.

  9. Choose Review and Launch.

  10. On the Review Instance Launch page, choose Launch. When prompted for a key pair, choose Proceed without a key pair.

    Note

    For the purposes of this tutorial, you can proceed without a key pair. To use SSH to connect to your instances, create or use a key pair.

    When you are ready, select the acknowledgment check box, and then choose Launch Instances.

  11. Choose View Instances to close the confirmation page and return to the console.

  12. You can view the status of the launch on the Instances page. When you launch an instance, its initial state is pending. After the instance starts, its state changes to running, and it receives a public DNS name. (If the Public DNS column is not displayed, choose the Show/Hide icon, and then select Public DNS.)

  13. It can take a few minutes for the instance to be ready for you to connect to it. Check that your instance has passed its status checks. You can view this information in the Status Checks column.

Step 3: Create an application in CodeDeploy

In CodeDeploy, an application is an identifier, in the form of a name, for the code you want to deploy. CodeDeploy uses this name to ensure the correct combination of revision, deployment configuration, and deployment group are referenced during a deployment. You select the name of the CodeDeploy application you create in this step when you create your pipeline later in this tutorial.

To create an application in CodeDeploy

  1. Open the CodeDeploy console at https://console.aws.amazon.com/codedeploy.

  2. If the Applications page does not appear, on the AWS CodeDeploy menu, choose Applications.

  3. Choose Create application.

  4. In Application name, enter MyDemoApplication.

  5. In Compute Platform, choose EC2/On-premises.

  6. Choose Create application.

To create a deployment group in CodeDeploy

  1. On the page that displays your application, choose Create deployment group.

  2. In Deployment group name, enter MyDemoDeploymentGroup.

  3. In Service Role, choose a service role that trusts AWS CodeDeploy with, at minimum, the trust and permissions described in Create a Service Role for CodeDeploy. To get the service role ARN, see Get the Service Role ARN (Console).

  4. Under Deployment type, choose In-place.

  5. Under Environment configuration, choose Amazon EC2 Instances. Choose Name in the Key field, and in the Value field, enter MyCodePipelineDemo.

    Important

    You must choose the same value for the Name key here that you assigned to your EC2 instances when you created them. If you tagged your instances with something other than MyCodePipelineDemo, be sure to use it here.

  6. Under Deployment configuration, choose CodeDeployDefault.OneAtaTime.

  7. Under Load Balancer, clear Enable load balancing. You do not need to set up a load balancer or choose a target group for this example.

  8. In the Advanced section, leave the defaults.

  9. Choose Create deployment group.

Step 4: Create your first pipeline in CodePipeline

In this part of the tutorial, you create the pipeline. The sample runs automatically through the pipeline.

To create a CodePipeline automated release process

  1. Sign in to the AWS Management Console and open the CodePipeline console at http://console.aws.amazon.com/codesuite/codepipeline/home.

  2. On the Welcome page, Getting started page, or the Pipelines page, choose Create pipeline.

  3. In Step 1: Choose pipeline settings, in Pipeline name, enter MyFirstPipeline.

    Note

    If you choose another name for your pipeline, be sure to use that name instead of MyFirstPipeline for the rest of this tutorial. After you create a pipeline, you cannot change its name. Pipeline names are subject to some limitations. For more information, see Quotas in AWS CodePipeline.

  4. In Service role, do one of the following:

    • Choose New service role to allow CodePipeline to create a new service role in IAM. In Role name, the role and policy name both default to this format: AWSCodePipelineServiceRole-region-pipeline_name. For example, this is the service role created for this tutorial: AWSCodePipelineServiceRole-eu-west-2-MyFirstPipeline.

    • Choose Existing service role to use a service role already created in IAM. In Role name, choose your service role from the list.

  5. Leave the settings under Advanced settings at their defaults, and then choose Next.

  6. In Step 2: Add source stage, in Source provider, choose Amazon S3. In Bucket, enter the name of the S3 bucket you created in Step 1: Create an S3 bucket for your application. In S3 object key, enter the object key with or without a file path, and remember to include the file extension. For example, for SampleApp_Windows.zip, enter the sample file name as shown in this example:

    SampleApp_Windows.zip

    Choose Next step.

    Under Change detection options, leave the defaults. This allows CodePipeline to use Amazon CloudWatch Events to detect changes in your source bucket.

    Choose Next.

  7. In Step 3: Add build stage, choose Skip build stage, and then accept the warning message by choosing Skip again. Choose Next.

  8. In Step 4: Add deploy stage, in Deploy provider, choose AWS CodeDeploy. The Region field defaults to the same AWS Region as your pipeline. In Application name, enter MyDemoApplication, or choose the Refresh button, and then choose the application name from the list. In Deployment group, enter MyDemoDeploymentGroup, or choose it from the list, and then choose Next.

    Note

    The name Deploy is the name given by default to the stage created in the Step 4: Add deploy stage step, just as Source is the name given to the first stage of the pipeline.

  9. In Step 5: Review, review the information, and then choose Create pipeline.

  10. The pipeline starts to run. You can view progress and success and failure messages as the CodePipeline sample deploys a webpage to each of the Amazon EC2 instances in the CodeDeploy deployment.

Congratulations! You just created a simple pipeline in CodePipeline. The pipeline has two stages:

  • A source stage named Source, which detects changes in the versioned sample application stored in the S3 bucket and pulls those changes into the pipeline.

  • A Deploy stage that deploys those changes to EC2 instances with CodeDeploy.

Now, verify the results.

To verify your pipeline ran successfully

  1. View the initial progress of the pipeline. The status of each stage changes from No executions yet to In Progress, and then to either Succeeded or Failed. The pipeline should complete the first run within a few minutes.

  2. After Succeeded is displayed for the action status, in the status area for the Deploy stage, choose Details. This opens the AWS CodeDeploy console.

  3. In the Deployment group tab, under Deployment lifecycle events, choose an instance ID. This opens the EC2 console.

  4. On the Description tab, in Public DNS, copy the address, and then paste it into the address bar of your web browser. View the index page for the sample application you uploaded to your S3 bucket.

    The following page is the sample application you uploaded to your S3 bucket.

For more information about stages, actions, and how pipelines work, see CodePipeline concepts.

(Optional) Step 5: Add another stage to your pipeline

Now add another stage in the pipeline to deploy from staging servers to production servers using CodeDeploy. First, you create another deployment group in the CodePipelineDemoApplication in CodeDeploy. Then you add a stage that includes an action that uses this deployment group. To add another stage, you use the CodePipeline console or the AWS CLI to retrieve and manually edit the structure of the pipeline in a JSON file, and then run the update-pipeline command to update the pipeline with your changes.

Create a second deployment group in CodeDeploy

Note

In this part of the tutorial, you create a second deployment group, but deploy to the same Amazon EC2 instances as before. This is for demonstration purposes only. It is purposely designed to fail to show you how errors are displayed in CodePipeline.

To create a second deployment group in CodeDeploy

  1. Open the CodeDeploy console at https://console.aws.amazon.com/codedeploy.

  2. Choose Applications, and in the list of applications, choose MyDemoApplication.

  3. Choose the Deployment groups tab, and then choose Create deployment group.

  4. On the Create deployment group page, in Deployment group name, enter a name for the second deployment group (for example, CodePipelineProductionFleet).

  5. In Service Role, choose the same CodeDeploy service role you used for the initial deployment (not the CodePipeline service role).

  6. Under Deployment type, choose In-place.

  7. Under Environment configuration, choose Amazon EC2 Instances. Choose Name in the Key box, and in the Value box, choose MyCodePipelineDemo from the list. Leave the default configuration for Deployment settings.

  8. Under Deployment configuration, choose CodeDeployDefault.OneAtaTime.

  9. Under Load Balancer, clear Enable load balancing.

  10. Choose Create deployment group.

Add the deployment group as another stage in your pipeline

Now that you have another deployment group, you can add a stage that uses this deployment group to deploy to the same EC2 instances you used earlier. You can use the CodePipeline console or the AWS CLI to add this stage.

Create a third stage (console)

You can use the CodePipeline console to add a new stage that uses the new deployment group. Because this deployment group is deploying to the EC2 instances you've already used, the deploy action in this stage fails.

  1. Sign in to the AWS Management Console and open the CodePipeline console at http://console.aws.amazon.com/codesuite/codepipeline/home.

  2. In Name, choose the name of the pipeline you created, MyFirstPipeline.

  3. On the pipeline details page, choose Edit.

  4. On the Edit page, choose + Add stage to add a stage immediately after the Deploy stage.

  5. In Add stage, in Stage name, enter Production. Choose Add stage.

  6. In the new stage, choose + Add action group.

  7. In Edit action, in Action name, enter Deploy-Second-Deployment. In Action provider, under Deploy, choose AWS CodeDeploy.

  8. In the CodeDeploy section, in Application name, choose MyDemoApplication from the drop-down list, as you did when you created the pipeline. In Deployment group, choose the deployment group you just created, CodePipelineProductionFleet. In Input artifacts, choose the input artifact from the source action. Choose Save.

  9. On the Edit page, choose Save. In Save pipeline changes, choose Save.

  10. Although the new stage has been added to your pipeline, a status of No executions yet is displayed because no changes have triggered another run of the pipeline. You must manually rerun the last revision to see how the edited pipeline runs. On the pipeline details page, choose Release change, and then choose Release when prompted. This runs the most recent revision available in each source location specified in a source action through the pipeline.

    Alternatively, to use the AWS CLI to rerun the pipeline, from a terminal on your local Linux, macOS, or Unix machine, or a command prompt on your local Windows machine, run the start-pipeline-execution command, specifying the name of the pipeline. This runs the application in your source bucket through the pipeline for a second time.

    aws codepipeline start-pipeline-execution --name MyFirstPipeline

    This command returns a pipelineExecutionId object.

  11. Return to the CodePipeline console and in the list of pipelines, choose MyFirstPipeline to open the view page.

    The pipeline shows three stages and the state of the artifact running through those three stages. It might take up to five minutes for the pipeline to run through all stages. You see the deployment succeeds on the first two stages, just as before, but the Production stage shows the Deploy-Second-Deployment action failed.

  12. In the Deploy-Second-Deployment action, choose Details. You are redirected to the page for the CodeDeploy deployment. In this case, the failure is the result of the first instance group deploying to all of the EC2 instances, leaving no instances for the second deployment group.

    Note

    This failure is by design, to demonstrate what happens when there is a failure in a pipeline stage.

Create a third stage (CLI)

Although using the AWS CLI to add a stage to your pipeline is more complex than using the console, it provides more visibility into the structure of the pipeline.

To create a third stage for your pipeline

  1. Open a terminal session on your local Linux, macOS, or Unix machine, or a command prompt on your local Windows machine, and run the get-pipeline command to display the structure of the pipeline you just created. For MyFirstPipeline, you would type the following command:

    aws codepipeline get-pipeline --name "MyFirstPipeline"

    This command returns the structure of MyFirstPipeline. The first part of the output should look similar to the following:

    { "pipeline": { "roleArn": "arn:aws:iam::80398EXAMPLE:role/AWS-CodePipeline-Service", "stages": [ ...

    The final part of the output includes the pipeline metadata and should look similar to the following:

    ... ], "artifactStore": { "type": "S3" "location": "codepipeline-us-east-2-250656481468", }, "name": "MyFirstPipeline", "version": 4 }, "metadata": { "pipelineArn": "arn:aws:codepipeline:us-east-2:80398EXAMPLE:MyFirstPipeline", "updated": 1501626591.112, "created": 1501626591.112 } }
  2. Copy and paste this structure into a plain-text editor, and save the file as pipeline.json. For convenience, save this file in the same directory where you run the aws codepipeline commands.

    Note

    You can pipe the JSON directly into a file with the get-pipeline command as follows:

    aws codepipeline get-pipeline --name MyFirstPipeline >pipeline.json
  3. Copy the Deploy stage section and paste it after the first two stages. Because it is a deploy stage, just like the Deploy stage, you use it as a template for the third stage.

  4. Change the name of the stage and the deployment group details.

    The following example shows the JSON you add to the pipeline.json file after the Deploy stage. Edit the emphasized elements with new values. Remember to include a comma to separate the Deploy and Production stage definitions.

    , { "name": "Production", "actions": [ { "inputArtifacts": [ { "name": "MyApp" } ], "name": "Deploy-Second-Deployment", "actionTypeId": { "category": "Deploy", "owner": "AWS", "version": "1", "provider": "CodeDeploy" }, "outputArtifacts": [], "configuration": { "ApplicationName": "CodePipelineDemoApplication", "DeploymentGroupName": "CodePipelineProductionFleet" }, "runOrder": 1 } ] }
  5. If you are working with the pipeline structure retrieved using the get-pipeline command, you must remove the metadata lines from the JSON file. Otherwise, the update-pipeline command cannot use it. Remove the "metadata": { } lines and the "created", "pipelineARN", and "updated" fields.

    For example, remove the following lines from the structure:

    "metadata": { "pipelineArn": "arn:aws:codepipeline:region:account-ID:pipeline-name", "created": "date", "updated": "date" }

    Save the file.

  6. Run the update-pipeline command, specifying the pipeline JSON file, similar to the following:

    aws codepipeline update-pipeline --cli-input-json file://pipeline.json

    This command returns the entire structure of the updated pipeline.

    Important

    Be sure to include file:// before the file name. It is required in this command.

  7. Run the start-pipeline-execution command, specifying the name of the pipeline. This runs the application in your source bucket through the pipeline for a second time.

    aws codepipeline start-pipeline-execution --name MyFirstPipeline

    This command returns a pipelineExecutionId object.

  8. Open the CodePipeline console and choose MyFirstPipeline from the list of pipelines.

    The pipeline shows three stages and the state of the artifact running through those three stages. It might take up to five minutes for the pipeline to run through all stages. Although the deployment succeeds on the first two stages, just as before, the Production stage shows that the Deploy-Second-Deployment action failed.

  9. In the Deploy-Second-Deployment action, choose Details to see details of the failure. You are redirected to the details page for the CodeDeploy deployment. In this case, the failure is the result of the first instance group deploying to all of the EC2 instances, leaving no instances for the second deployment group.

    Note

    This failure is by design, to demonstrate what happens when there is a failure in a pipeline stage.

(Optional) Step 6: Disable and enable transitions between stages in CodePipeline

You can enable or disable the transition between stages in a pipeline. Disabling the transition between stages allows you to manually control transitions between one stage and another. For example, you might want to run the first two stages of a pipeline, but disable transitions to the third stage until you are ready to deploy to production, or while you troubleshoot a problem or failure with that stage.

To disable and enable transitions between stages in a CodePipeline pipeline

  1. Open the CodePipeline console and choose MyFirstPipeline from the list of pipelines.

  2. On the details page for the pipeline, choose the Disable transition button between the second stage (Deploy) and the third stage that you added in the previous section (Production).

  3. In Disable transition, enter a reason for disabling the transition between the stages, and then choose Disable.

    The arrow between stages displays an icon and color change, and the Enable transition button.

  4. Upload your sample again to the S3 bucket. Because the bucket is versioned, this change starts the pipeline. For information, see Upload the sample application.

  5. Return to the details page for your pipeline and watch the status of the stages. The pipeline view changes to show progress and success on the first two stages, but no changes occur on the third stage. This process might take a few minutes.

  6. Enable the transition by choosing the Enable transition button between the two stages. In the Enable transition dialog box, choose Enable. The stage starts running in a few minutes and attempts to process the artifact that has already been run through the first two stages of the pipeline.

    Note

    If you want this third stage to succeed, edit the CodePipelineProductionFleet deployment group before you enable the transition, and specify a different set of EC2 instances where the application is deployed. For more information about how to do this, see Change deployment group settings. If you create more EC2 instances, you might incur additional costs.

Step 7: Clean up resources

You can use some of the resources you created in this tutorial for the Tutorial: Create a four-stage pipeline. For example, you can reuse the CodeDeploy application and deployment. You can configure a build action with a provider such as CodeBuild, which is a fully managed build service in the cloud. You can also configure a build action that uses a provider with a build server or system, such as Jenkins.

However, after you complete this and any other tutorials, you should delete the pipeline and the resources it uses, so that you are not charged for the continued use of those resources. First, delete the pipeline, then the CodeDeploy application and its associated EC2 instances, and finally, the S3 bucket.

To clean up the resources used in this tutorial

  1. To clean up your CodePipeline resources, follow the instructions in Delete a pipeline in AWS CodePipeline.

  2. To clean up your CodeDeploy resources, follow the instructions in To clean up resources (console).

  3. To delete the S3 bucket, follow the instructions in Deleting or emptying a bucket. If you do not intend to create more pipelines, delete the S3 bucket created for storing your pipeline artifacts. For more information about this bucket, see CodePipeline concepts.
