Address limitations with the AWS CLI The most frequent use case for the AWS Credentials Variables task is to address scenarios not (yet) covered by dedicated tasks, see How to work around limitations with the AWS Command Line Interface (AWS CLI) for details. |
To configure an AWS 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 AWS Credentials Variables task, or click Add Task and then AWS 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. |
Add Caller Identity | Check to add variables with details about the IAM identity whose credentials are used to call the API (see get-caller-identity). Clear to skip the additional API call required to retrieve these details. |
Bamboo Variables | |
Namespace | Provide the namespace for generated variables |
Scope | Select the scope for generated variables:
|
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 |
Role ARN | (Conditional | Optional) Specify the ARN of another role that the agent's IAM role for EC2 should assume. |
AWS Credentials Sources
IAM Policy
The AWS Credentials Variables task requires IAM permissions to retrieve temporary security credentials via the AWS Security Token Service (STS) - an all-encompassing policy might look as follows:
| Code Block |
|---|
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"sts:AssumeRole",
"sts:GetFederationToken",
"sts:GetSessionToken"
],
"Resource": [
"*"
]
}
]
} |
Refer to Granting Permissions to Create Temporary Security Credentials for details on how to create more granular/secure policies, for example:
remove permissions for any Action allowing unused principal types
further restrict permissions via more specific Resource declarations
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
| Code Block | ||
|---|---|---|
| ||
${bamboo.custom.aws.accessKeyId}
${bamboo.custom.aws.secretAccessKey.password}
${bamboo.custom.aws.sessionToken.password}
${bamboo.custom.aws.connector.id}
${bamboo.custom.aws.connector.name}
# Optional: the callerIdentity namespace is only present when option 'Add Caller Identity' is checked.
${bamboo.custom.aws.callerIdentity.account}
${bamboo.custom.aws.callerIdentity.arn}
${bamboo.custom.aws.callerIdentity.userId} |
- The '
*.password' suffix ensures that these 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)
| Code Block | ||
|---|---|---|
| ||
${bamboo.custom.aws.credentials.json.password}
# Optional: the callerIdentity namespace is only present when option 'Add Caller Identity' is checked.
${bamboo.custom.aws.callerIdentity.json} |
Environment variables
Aforementioned variables will also be available as environment variables for use in Bamboo Script tasks. The syntax differs between shells, as illustrated in these examples for assigning them to the standardized variables used by tools like the AWS Command Line Interface (AWS CLI):
Bash (Unix shell)
| Code Block | ||
|---|---|---|
| ||
export AWS_ACCESS_KEY_ID=$bamboo_custom_aws_accessKeyId export AWS_SECRET_ACCESS_KEY=$bamboo_custom_aws_secretAccessKey_password export AWS_SESSION_TOKEN=$bamboo_custom_aws_sessionToken_password |
PowerShell
| Code Block | ||
|---|---|---|
| ||
$Env:AWS_ACCESS_KEY_ID = $Env:bamboo_custom_aws_accessKeyId $Env:AWS_SECRET_ACCESS_KEY = $Env:bamboo_custom_aws_secretAccessKey_password $Env:AWS_SESSION_TOKEN = $Env:bamboo_custom_aws_sessionToken_password |
Windows Command Prompt (cmd)
| Code Block | ||
|---|---|---|
| ||
set AWS_ACCESS_KEY_ID=%bamboo_custom_aws_accessKeyId% set AWS_SECRET_ACCESS_KEY=%bamboo_custom_aws_secretAccessKey_password% set AWS_SESSION_TOKEN=%bamboo_custom_aws_sessionToken_password% |
