When using cloud-native builds, you are essentially distributing build tasks to various build nodes for execution.
These nodes perform build tasks using a specified Docker image as the build environment.

Configuration Method

In the pipeline configuration, you can specify the pipeline.runner.tags property to select different build nodes.
By specifying the pipeline.runner.cpus property, you can configure the maximum number of CPU cores to be used.

The official available tags is as follows:

1. cnb:arch:amd64
   • The CPU with the amd64 architecture.
   • The runner.cpus can be configured in the range of 1 to 64, with a default value of 8.
   • Cloud-Native Build - Maximum Available Time 20 hours.
   • Cloud-Native Development - Maximum Available Time 18 hours.
2. cnb:arch:arm64:v8
   • The CPU with the arm64/v8 architecture.
   • The runner.cpus can be configured in the range of 1 to 16, with a default value of 8.
   • Cloud-Native Build - Maximum Available Time 20 hours.
   • Cloud-Native Development - Maximum Available Time 18 hours.
3. cnb:arch:amd64:gpu
   • The CPU with the amd64 architecture.
   • The runner.cpus is fixed at 16.
   • The GPU memory has a maximum of 48GB, operating in shared mode.
   • Cloud-Native Build - Maximum Available Time 4 hours
   • Cloud-Native Development - Maximum Available Time 4 hours
4. cnb:arch:amd64:gpu:H20 -- Not recommended, as H20 has been discontinued
   • The CPU with the amd64 architecture.
   • The runner.cpus is fixed at 32.
   • The GPU memory has a maximum of 96GB, operating in shared mode.
   • Cloud-Native Build - Maximum Available Time 4 hours.
   • Cloud-Native Development - Maximum Available Time 4 hours.
5. cnb:arch:amd64:gpu:L40
   • The CPU with the amd64 architecture.
   • The runner.cpus is fixed at 16.
   • The GPU memory has a maximum of 48GB, operating in shared mode.
   • Cloud-Native Build - Maximum Available Time 4 hours.
   • Cloud-Native Development - Maximum Available Time 4 hours.

Example:

main:
  push:
    - runner:
        # Execute on amd64 build node
        tags: cnb:arch:amd64
        cpus: 8
      stages:
        - name: uname
          script: uname -a

    - runner:
        # Execute on arm64/v8 build node
        tags: cnb:arch:arm64:v8
        cpus: 8
      stages:
        - name: uname
          script: uname -a

$:
  vscode:
    - runner:
        # Start a remote development environment with GPU access
        tags: cnb:arch:amd64:gpu
      services:
