AWS CodePipeline

Set up a Continuous Deployment Pipeline

Follow the following steps to set up a continuous deployment pipeline.

Step 1: Create a deployment environment

A target environment with virtual servers or Amazon EC2 instances will be required for our continuous deployment workflow to install sample code. This environment will be prepared before the pipeline is built. To make the process of setting up and configuring EC2 instances for this course easier, you'll use AWS Elastic Beanstalk to create a sample environment. Elastic Beanstalk allows you to host web applications without having to set up, configure, or manage your own virtual servers. It manages the infrastructure (virtual servers, load balancers, and so on) as well as the application stack (OS, language and framework, web and application server, and so on) for you.

Step 2: Get a copy of the sample code

You'll get a copy of the sample app's code and choose a source to host it in this stage. The pipeline extracts code from a source and then executes it.

Step 3: Create your pipeline

Create and set up a small pipeline with two actions: source and deploy in this stage. The locations of your source repository and deployment environment will be provided to CodePipeline.

Step 4: Activate your pipeline to deploy your code

This is where your pipeline will be launched. Your pipeline will begin to run automatically after it has been created. It first finds the sample app code in your source directory, bundles the files, and moves them to the second stage you specified. It delivers the code to Elastic Beanstalk during this stage, which holds the EC2 instance that will host your code. The code is deployed to the EC2 instance using Elastic Beanstalk.

Step 5: Commit a change and then update your app

You will revise the sample code and commit the update to your repository in this step. CodePipeline will automatically detect your changed sample code and begin deploying it to your EC2 instance using Elastic Beanstalk.

The sample web page you deployed refers to AWS CodeDeploy, an automated code deployment service. CodeDeploy is an alternative to Elastic Beanstalk for deployment actions in CodePipeline. Let's edit the sample code to reflect the fact that you used Elastic Beanstalk to deploy the sample.

Frequently Asked Questions

What is the Availability Zone?

AWS Cloud computing resources are housed in a given place. Within an AWS Region, Availability Zones are connected with low latency, high throughput, and highly redundant networking. They are also physically segregated and isolated from one another. For redundancy, you can build MediaConnect flows in separate Availability Zones.

What is the AWS region?

A geographical area including one or more Availability Zones. Each AWS Region operates independently of the others. To distribute material to receivers in different parts of the world, you can construct MediaConnect flows in distinct Regions.

What is CDI flow?

A MediaConnect flow that transfers JPEG XS-lightly compressed high-quality material. The content is decoded into independent audio, video, and ancillary data media streams. Multiple media streams can be used for the source and multiple media streams can be used for each output in a CDI flow. To ingest content that corresponds to the SMPTE 2110, part 22 transport standard, MediaConnect leverages AWS Cloud Digital Interface (AWS CDI) network technology.

What do you mean by Distribution?

The result of creating outputs that point to MediaConnect flows in other AWS Regions, for the purpose of delivering content to different geographical locations.

Can a CodePipeline trigger another pipeline?

Assume both CodePipelines are in the same account. In your buildspec.yml, you can include a "post-build" step. You can use AWS SDK commands to start the second CodePipeline in the post-build phase.
