Increase vCPU for builds

This page describes how you can increase vCPU for your builds.

By default, Cloud Build runs your builds on a standard virtual machine (VM). In addition to the standard VM, Cloud Build provides several high-CPU VM types to run builds. To increase the speed of your build, select a machine with a higher vCPU to run builds. Keep in mind that although selecting a high vCPU machine increases your build speed, it may also increase the startup time of your build as Cloud Build only starts non-standard machines on demand.

If you require more vCPU options than the ones provided by default pools, you can choose to run your builds on private pools, which provides a number of high-CPU machine types for builds.

To learn more about the all the available machine types, see the Pricing page.

Before you begin

To use the command-line examples in this guide, install and configure the Google Cloud CLI.

  • If you've installed gcloud CLI previously, make sure you have the latest available version by running gcloud components update.

Increase vCPU for default pools

You can increase the vCPU for running builds in a default pool either by passing the value directly to the gcloud builds submit command or by specifying the value in the build config file.

Pass the value directly to the gcloud builds submit command:

To specify a custom VM size directly in the gcloud builds submit command, add the --machine-type argument to the command:

gcloud builds submit --config=cloudbuild.yaml \
    --machine-type=N1_HIGHCPU_8 .

Specify the value in the build config file:

YAML

  1. Open your build config file.

  2. Update the machineType field to an enum value corresponding to one of the supported machine types for default pools. The following example shows how to add the machineType option to a build config file:

    steps:
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '-t', 'gcr.io/my-project/image1', '.']
options:
  machineType: 'N1_HIGHCPU_8'

  3. Start the build using the gcloud CLI or build triggers.

JSON

  1. Open your build config file.

  2. Update the machineType field to an enum value corresponding to one of the supported machine types for default pools. The following example shows how to add the machineType option to a build config file:

    {
    "steps": [
    {
        "name": "gcr.io/cloud-builders/docker",
        "args": ["build", "-t", "gcr.io/my-project/image1", "."]
    },
    "options": {
        "machineType": "N1_HIGHCPU_8"
    }
}

  3. Start the build using the gcloud CLI or build triggers.

Increase vCPU for private pools

Console

  1. Open the Worker pool page in the Google Cloud console:

    Open the Cloud Build worker pool page

  2. Select the project in which you created the private pool.

  3. Click on the private pool name.

  4. In the Edit private pool side panel, use the Machine type drop-down to select a larger machine type.

  5. Click Save.

gcloud

You can increase the vCPU for running builds in a private pool either by passing the value directly to the gcloud builds worker-pools update command or by specifying the value in the private pool config file.

Specify the value in the private pool config file:

  1. Open your private pool config file.

  2. Update the value of machineType field to one of the supported machine types .

  3. Run the following command, where PRIVATEPOOL_ID is the unique identifier for your private pool, REGION is the region where your private pool is located, and PRIVATEPOOL_CONFIG_FILE is the name of your private pool config file:

    gcloud builds worker-pools update PRIVATEPOOL_ID \
    --region=REGION \
    --config-from-file=PRIVATEPOOL_CONFIG_FILE

Pass the value directly to the gcloud builds worker-pools update command:

   gcloud builds worker-pools update PRIVATEPOOL_ID  \
       --region=REGION \
       --worker-machine-type=PRIVATEPOOL_MACHINE_TYPE

Replace the placeholder values in the above commands with the following:

  • PRIVATEPOOL_ID: the ID of your existing private pool. You cannot update this value; you must specify an existing private pool ID.
  • REGION: the region where you created your private pool.
  • PRIVATEPOOL_DISK_SIZE: the updated disk size.

  • PRIVATEPOOL_MACHINE_TYPE is the updated machine type.

    Cloud Build uses the updated machine type anytime you run builds using corresponding private pool.
