Based on the Docker ecosystem, it abstracts environments, caches, and plugins, helping developers build software in a cooler way through declarative syntax.

• Declarative: Declarative syntax, programmable and easy to share.
• Easy to manage: Managed alongside code from the same source.
• Cloud Native: Resource pooling that shields infrastructure complexity.

Declarative Build Environment

.cnb.yml

main:
  push:
    - docker:
        image: node:20
      stages:
        - node -v
        - npm install
        - npm test

Declarative Build Cache

.cnb.yml

main:
  push:
    - docker:
        image: node:20
        volumes:
          - /root/.npm:copy-on-write
      stages:
        - node -v
        - npm install
        - npm test

Docker as Task Execution Environment

.cnb.yml

main:
  push:
    - stages:
        - name: run with node 20
          image: node:20
          script: node -v
        - name: run with node 21
          image: node:21
          script: node -v

Docker Ecosystem Based Plugins

.cnb.yml

main:
  push:
    - stages:
        - name: hello world
          image: cnbcool/hello-world

On-demand Computing Resources

.cnb.yml

main:
  push:
    - runner:
        cpus: 64
      docker:
        image: node:20
      stages:
        - node -v
        - npm install
        - npm test

Workspaces

.cnb.yml

$:
  vscode:
    - runner:
        cpus: 64
      services:
        - vscode
      docker:
        image: node:20
        volumes:
          - node_modules:copy-on-write
      stages:
        - npm install

High Performance

CPU Freedom

• runner.cpus

Through runner.cpus, you can declare required CPU resources on demand, up to 64 cores.

Second-level Cloning

Based on OverlayFS, git-clone-yyds can complete code preparation in seconds, easily supporting 100GB+ super large repositories.

Concurrent Caching

• copy-on-write

copy-on-write enables copy-on-write for caches, eliminating concerns about cache read-write conflicts in concurrent scenarios.

.cnb.yml

main:
  push:
    - runner:
        cpus: 64
      docker:
        image: node:20
        volumes:
          - /root/.npm:copy-on-write
      stages:
        - node -v
        - npm install
        - npm test
