Test Scenarios

> 3000 concurrent CI Executions [INLINE]

Each CI pipeline would

  • initialise a k8s pod and git clone repo
  • run 5 parallel steps (100 sec sleep)
  • run template with 2 parallel steps (140sec sleep)

Projects : 1
Pipelines : 3000
Stages per pipeline : 1
Delegates : 15 (1cpu/4gi)
Trigger type : webhook
Test class : CI_PIPELINE_WEBHOOK_RUN

Result : PASS
Avg Execution Time: 6min 36sec

> 2300 concurrent CD Executions [INLINE]

Each CD pipeline would

  • fetch docker artifact from AWS ECR repo
  • run following steps in order:
    • Canary deploy
    • Canary delete
    • Rolling deploy
    • K8s Delete

Projects : 1
Pipelines : 2300
Stages per pipeline : 1
Delegates : 60 (1cpu/4gi)
Test class : CD_PIPELINE_WEBHOOK_RUN

Result : PASS
Avg Execution Time: 6min 4sec
