1. Elixir Releases
3. The Way /app/*.rb /lib/*.rb Gemfile $ install requirements $ export RAILS_ENV=production $ bundle install $ bundle exec rails server
4. gjaldon/heroku-buildpack-phoenix-static HashNuke/heroku-buildpack-elixir
5. ?
6. Build Run $ mix deps.get $ mix release $ _build/app start app.tar.gz: - Binaries - Erlang runtime (optional) - Sources (optional)
7. Watch Out
8. Build Run $ mix deps.get $ mix release —env=prod $ _build/app start app.tar.gz
9. $ docker run image_that_is_like_runtime build.sh
10. $ _build/app start ** (Postgrex.Error) ERROR 42P01 (undefined_table): relation "users" does not exist
11. $ mix ecto.migrate -bash: mix: command not found
12. $ _build/app migrate $ _build/app start https://github.com/bitwalker/distillery/blob/master/docs/Running%20Migrations.md
13. Configuration staging demo testing sandbox production
14. use Mix.Config config :app, App.Repo, [ database: "app", username: "user", password: "supersecret", hostname: “db-server”, port: 5432, ] {'Elixir.QualityControl.Repo', [{database,<<"app">>}, {username,<<“user">>}, {password,<<"supersecret">>}, {hostname,<<“db-server”>>}, {loggers,[]}, {port,5433}]}, config.exs sys.config
15. use Mix.Config config :app, App.Repo, [ database: "app", username: “user", password: System.get_env(“PG_PASS"), hostname: “db-server”, port: 5432, ] config.exs sys.config {'Elixir.QualityControl.Repo', [{database,<<"app">>}, {username,<<“user">>}, {password,nil}, {hostname,<<“db-server”>>}, {loggers,[]}, {port,5433}]},
16. Replace Variables on Build System {:system, ENV, default} Check In Credentials REPLACE_OS_VARS=true Build Config Layer
17. Why
18. Because it's cool?
19. Size 300 MB 50 MB
20. Resources
21. Code Reload
22. Comfortable
23. Start Early Think About Config Use Distillery
