aws codepipeline / 在新提交上取消当前正在运行的管道

Question

new to codepipeline;

user A pushes, pipeline `run A` is starting.  

1 min. later, user B pushes, `run A` in progress, \
new pipeline `run B` is stacked pending, until `run A` is done.

Is it possible to configure things, so that, a running pipeline is automatically cancelled when a new run (commit) is stacked?

'Translating' the example above: :

user A pushes, pipeline `run A` is starting.  

1 min. later, user B pushes, `run A` is cancelled,
`run B` starts right away

Answer 1

TL;DR CodePipeline does not have out-of-the-box execution interruption, but you could implement it yourself.

Pipeline executions work by applying three rules:

1. Stages are locked when an execution is being processed
2. Subsequent executions wait for the stage to be unlocked
3. Waiting executions are superseded by more recent executions

Executions patiently wait their turn. The CLI and SDK have APIs to stop an execution and get info about executions . You could implement execution interruptions yourself by running some business logic using these APIs at the start of each new execution.

Could, but should? A 1:1 correspondence between commit and successful pipeline execution ensures you have a clean, tested rollback state at all times.
