Our sample pipeline

37. Sample 3Sample 3
 Activate a repo
 Review the simplest Drone pipeline
 Generate a trigger via git push
 Show build logs
 Show how the workspace is mounted in build steps

38. A pipeline is an ordered list of build steps

39. Plugin steps or custom steps

40. The clone step is implicit and is always first

41. A workspace is shared across all steps

42. Sample 4Sample 4
 Base pipeline: executing tests with in-memory
database
 Testing a build

43. Sample 5Sample 5
 Using services
 The problem with credentials. Managing secrets
 Base pipeline: executing tests against a real database

44. Services are dependencies of the build
