6. outgrowing Travis CI long build times flakiness low throughput
7. solution self-hosting
8. custom CI simpler for a small problem flexible no additional knowledge required
9. aircloak air cloak central common integration_test ci ...
11. GitHub poller GitHub poll list of branches and PRs
12. aircloak_ci GitHub poller builds branch x pull request y
13. pull request x air cloak …
14. changed component tested components air air integration_test ci ci common everything
15. report success build components await approval report mergeability
16. if not merge_conflict?(build_state) and tests_passed?(build_state) and pr_approved?(build_state) do: report_mergeable(build_state)
17. Github.comment_on_issue( build_state, "Pull request can be merged #{AircloakCI.Emoji.happy()}" ) Github.put_status_check_state( build_state, "continuous-integration/aircloak/mergeable", "pull request can be merged", :success )
19. %{ compile: [ "mix deps.get", "mix compile" ], test: [ "mix test", "mix dialyze", "mix format --check-formatted" ] }
20. test_test = # ... test_dev = # ... test_prod = # ... %{ compile: # ..., test: [test_test, test_dev, test_prod] }
21. # sequence of commands [ "mix deps.get", "mix compile" ]
22. # also a sequence {:sequence, [ "mix deps.get", "mix compile" ]}
23. # independent commands {:parallel, [ "mix format --check-formatted", "mix test", "mix dialyze", ]}
24. {:sequence, [ "command a", {:parallel, [ "command b", {:sequence, [ "command c", "command d" ]}, "command e" ]}, "command f" ]}
25. command a command b command c command e command d command f
26. component command 1 command 2 …
27. build component 1 component 2 …
28. builds build 1 build 2 …
29. not open-source (yet!)
31. uniformity simpler development simpler testing simpler deployment simpler maintenance improved collaboration
