43. #babylonLondroid Our experience with Jenkins pipelines
44. #babylonLondroid Problems before we started
45. #babylonLondroid
46. #babylonLondroid
47. #babylonLondroid #babylonLondroid Our new workflow
48. #babylonLondroid How did pipelines help?
49. #babylonLondroid Decreased build times
50. #babylonLondroid Per-branch CI config
51. #babylonLondroid Developers + Devops =
52. #babylonLondroid Config easier to modify
53. #babylonLondroid What did we learn?
54. #babylonLondroid Don’t store credentials in your pipeline script
55. #babylonLondroid Use good coding practices
56. #babylonLondroid Build your own tools or use libraries
57. #babylonLondroid
58. #babylonLondroid
59. #babylonLondroid Lots of trial and error
60. #babylonLondroid Not all plugins support pipelines
61. #babylonLondroid The default pipeline view plugin is

65. #babylonLondroid Summing up
66. #babylonLondroid If you can use pipelines with your CI / SCM, do it! Avoid a world of hurt
