Using the Amazon ECR Credentials Variables task in Bamboo

Use the Amazon ECR Credentials Variables task to provide temporary Amazon Elastic Container Registry (Amazon ECR) authentication credentials for other tools by injecting them into AWS unaware tasks like the Bamboo Docker task. This improves versatility for using tools that are not directly integrated with Identity Federation for AWS, but accept AWS credentials via the command line, environment variables or the Bamboo task interface.

Configuration

Use Amazon ECR Credentials with Bamboo Docker task

The most frequent use case for the Amazon ECR Credentials Variables task is to enable the built-in Bamboo Docker task to push images to an Amazon ECR repository - refer to How to push a Docker image to a repository in your Amazon ECR registry with the Bamboo Docker task for details.

To configure an Amazon ECR Credentials Variables task:

Navigate to the Tasks configuration tab for the job (this will be the default job if creating a new plan).
Click the name of an existing Amazon ECR Credentials Variables task, or click Add Task and then Amazon ECR Credentials Variables to create a new task.
Complete the following settings:

Task Description	(Optional) Identify the purpose of the task.
Disable this task	Check, or clear, to selectively run this task.
Region	Select the desired AWS Region. Alternatively, select [Use region variable ...] to supply the region dynamically via Bamboo variables (needs to be a region code such as `ap-southeast-2`) - refer to How to parametrize the AWS region via a Bamboo variable for details.
Registry ID	(Optional) Select the AWS account ID that is associated with the registry for which to get authorization credentials If you do not specify a registry, the default registry is assumed. Refer to How can I grant access to a secondary account to pull or push images in my ECR repository? for details on the required permissions when using non default registries.
Bamboo Variables
Namespace	Provide the namespace for generated variables
Scope	Select the scope for generated variables: Local – Variables will only be available in this job Result – Variables will be available in subsequent plan stages and deployment releases
AWS Security Credentials
Source	Select the AWS Credentials Source (see below). Can be either Identity Federation for AWS or an IAM Role for EC2.
Connector	(Conditional) Select the shared Identity Federation for AWS Connector. Alternatively, select [Use connector variable ...] to supply the connector dynamically via Bamboo variables (needs to be a connector id such as `f24e81bc-7aff-42db-86a2-7cf82e24d871`) - refer to How to parametrize the AWS connector via a Bamboo variable for details.
Role ARN	(Conditional \| Optional) Specify the ARN of another role that the agent's IAM role for EC2 should assume.

AWS Credentials Sources

Managed IAM Policy

We recommend to facilitate an available AWS Managed Policy to ease permission maintenance - the Amazon ECR Credentials Variables task requires the permissions in the AmazonEC2ContainerRegistryPowerUser managed policy, which at the time of this writing looks as follows:

{
    "Version": "2012-10-17",
    "Statement": [{
        "Effect": "Allow",
        "Action": [
            "ecr:GetAuthorizationToken",
            "ecr:BatchCheckLayerAvailability",
            "ecr:GetDownloadUrlForLayer",
            "ecr:GetRepositoryPolicy",
            "ecr:DescribeRepositories",
            "ecr:ListImages",
            "ecr:BatchGetImage",
            "ecr:InitiateLayerUpload",
            "ecr:UploadLayerPart",
            "ecr:CompleteLayerUpload",
            "ecr:PutImage"
        ],
        "Resource": "*"
    }]
}

You have the following options to provide AWS Security Credentials:

Usage

Bamboo variables

This task generates the following Bamboo variables for reuse in subsequent tasks without native integration with Identity Federation for AWS:

Bamboo variables

${bamboo.custom.aws.ecr.authorizationToken.password}
${bamboo.custom.aws.ecr.expirationDate}
${bamboo.custom.aws.ecr.proxyEndpoint}
${bamboo.custom.aws.ecr.proxyEndpointDomain}
${bamboo.custom.aws.ecr.username}
${bamboo.custom.aws.ecr.password}

The '*.password' suffix ensures that sensitive variables are masked with asterisks ('*******') in the Bamboo build log.

An alternative representation as a JSON object for automated processing with tools like jq is available too:

Bamboo variables (alternative representations)

${bamboo.custom.aws.ecr.credentials.json.password}

Environment variables

Aforementioned variables will also be available as environment variables for use in Bamboo Script tasks. The syntax differs between shells, as illustrated in these examples for assigning them to the standardized variables used by tools like the AWS Command Line Interface (AWS CLI):

Bash (Unix shell)

PowerShell

Windows Command Prompt (cmd)
