BuildVolumeSize

Build disk size in GB for the dedicated build instance's EBS volume.

| Default value | 100 |

Use Cases

• Increasing disk size for builds that produce large Docker images or pull many large base images
• Increasing when builds fail with "No space left on device" errors
• Reducing on Racks with small, lightweight builds to lower EBS storage costs

Additional Information

Note: Getting errors like "No space left on device" on your builds (not your running applications)? On a Rack with BuildMethod=ec2, extend the space on the device by increasing this parameter. On a Rack with BuildMethod=fargate, increase FargateBuildVolumeSize instead.

This parameter controls the EBS volume size attached to the build instance. It does not affect the volume size of runtime instances (see VolumeSize for that).

A Rack that builds on Fargate runs no build instance, so a change to this parameter is accepted and applied to the stack but never reaches a running builder. Use FargateBuildVolumeSize to size the Fargate builder's disk instead.

$ convox rack params set BuildVolumeSize=200
