DevOps / Bamboo: Continuous Integration & Deployment Interview Questions
How do you trigger Bamboo builds from Bitbucket webhooks?
Rather than having Bamboo repeatedly poll the repository for changes, Bitbucket can push a webhook notification to Bamboo the moment a commit lands, and Bamboo starts the build immediately.
- In the plan's trigger configuration, add a "Repository triggered" (webhook-based) trigger and select the linked repository.
- If the repository is Bitbucket Server/Data Center linked via an application link, Bamboo can register the webhook automatically; for other Git hosts it's added manually.
- For a manual setup, Bitbucket's repository settings get a webhook pointed at the Bamboo endpoint, for example:
POST https://bamboo.example.com/rest/api/latest/queue/PROJ-PLAN Content-Type: application/json
Once configured, a push shows up as a queued build within seconds instead of waiting for the next polling interval, which is the main reason webhook triggers have largely replaced polling triggers in current setups.
What is the main advantage of a webhook trigger over a polling trigger?
For a Bitbucket Server repository linked via an application link, how is the webhook usually registered?
