Pipeline steps are executed sequentially by default. You can optionally describe your build steps as a directed acyclic graph. In the below example we fan-out to execute the first two steps in parallel, and then once complete, we fan-in to execute the final step:
- name: backend
- go build
- go test
- name: frontend
- npm install
- npm test
- name: notify
The above example is quite simple, however, you can use this syntax to create very complex execution flows.
Note that when you define the dependency graph you must configure dependencies for all pipeline steps.
Note that you can use conditional steps in your dependency graph. The scheduler automatically corrects the dependency graph for skipped steps.
