Capacity

The initial number of machines allocated to the fleet, which defines the number of builds that can run in parallel.

Overflow behavior

Defines the behavior when the number of builds exceeds the fleet capacity.

On-demand

Overflow builds run on CodeBuild on-demand.

Note

If you choose to set your overflow behavior to on-demand while creating a VPC-connected fleet, make sure that you add the required VPC permissions to your project service role. For more information, see Example policy statement to allow CodeBuild access to AWS services required to create a VPC network interface.

Important

If you choose to set your overflow behavior to on-demand, note that overflow builds will be billed separately, similar to on-demand Amazon EC2. For more information, see https://aws.amazon.com/codebuild/pricing/.

Queue

Build runs are placed in a queue until a machine is available. This limits additional costs because no additional machines are allocated.

Amazon Machine Images (AMI)

The Amazon Machine Image (AMI) properties for your fleet. The following properties are supported by CodeBuild:

AWS Regions Organization ARN Organization ID
us-east-1 arn:aws:organizations::851725618577:organization/o-c6wcu152r1 o-c6wcu152r1
us-east-2 arn:aws:organizations::992382780434:organization/o-seufr2suvq o-seufr2suvq
us-west-2 arn:aws:organizations::381491982620:organization/o-0412o99a4r o-0412o99a4r
ap-southeast-2 arn:aws:organizations::767398067170:organization/o-6crt0f6bu4 o-6crt0f6bu4
eu-central-1 arn:aws:organizations::590183817084:organization/o-lb2lne3te6 o-lb2lne3te6
Additional configuration
VPC - optional

The VPC that your CodeBuild fleet will access. For more information, see Use AWS CodeBuild with Amazon Virtual Private Cloud.

Subnets

The VPC subnets that CodeBuild uses to set up your VPC configuration. Note that reserved capacity fleets support only one subnet in a single Availablity Zone. Also, ensure that your subnets include a NAT gateway.

Security groups

The VPC security groups that CodeBuild uses with your VPC. Ensure that your security groups allow outbound connections.

Fleet Service Role

Defines the service role for your fleet from an existing service role in your account.
