Docker in Custom Image Sample for AWS CodeBuild

This sample builds and runs a Docker image by using AWS CodeBuild and a custom Docker build image (docker:dind in Docker Hub).

To learn how to build a Docker image by using a build image provided by AWS CodeBuild with Docker support instead, see our Docker Sample.

Important

Running this sample may result in charges to your AWS account. These include possible charges for AWS CodeBuild and for AWS resources and actions related to Amazon S3, AWS KMS, and CloudWatch Logs. For more information, see AWS CodeBuild Pricing, Amazon S3 Pricing, AWS Key Management Service Pricing, and Amazon CloudWatch Pricing.

Running the Sample

To run this sample:

  1. Create the files as described in the Directory Structure and Files sections of this topic, and then upload them to an Amazon S3 input bucket or an AWS CodeCommit, GitHub, or Bitbucket repository.

    Important

    Do not upload (root directory name), just the files inside of (root directory name).

    If you are using an Amazon S3 input bucket, be sure to create a ZIP file that contains the files, and then upload it to the input bucket. Do not add (root directory name) to the ZIP file, just the files inside of (root directory name).

  2. Create a build project, run the build, and view related build information by following the steps in Run AWS CodeBuild Directly.

    If you use the AWS CLI to create the build project, the JSON-formatted input to thecreate-project command might look similar to this. (Replace the placeholders with your own values.)

    Copy
    { "name": "sample-docker-custom-image-project", "source": { "type": "S3", "location": "codebuild-region-ID-account-ID-input-bucket/DockerCustomImageSample.zip" }, "artifacts": { "type": "NO_ARTIFACTS" }, "environment": { "type": "LINUX_CONTAINER", "image": "docker:dind", "computeType": "BUILD_GENERAL1_SMALL", "privilegedMode": true }, "serviceRole": "arn:aws:iam::account-ID:role/role-name", "encryptionKey": "arn:aws:kms:region-ID:account-ID:key/key-ID" }
  3. To see the build results, look in the build's log for the string Hello, World!. For more information, see View Build Details.

Directory Structure

This sample assumes this directory structure.

Copy
(root directory name) |-- buildspec.yml `-- Dockerfile

Files

This sample uses these files.

buildspec.yml (in (root directory name))

Copy
