3. Demo repository github.com/idopterlabs/guitar_store Branches main and deploy-container.
4. Compiled vs. Interpreted
5. Compiled vs. Interpreted
6. Compiled vs. Interpreted No run time needed. ALL of the runtime needed. Some of the runtime.
9. • Some ops work • Visibility into the build process • Control over the prod. artifact • Portability: “Build once, run anywhere” • NO ops 😌 • Focus on development • Watch the magic happen 󰨸 • More abstractions between source code and prod. artifact • Vendor lock-in 󰤅 Heroku Buildpacks ⛏ Containers 🐳 The 2 Strategies:
10. Heroku Dashboard
11. Strategy #1 Buildpacks ⛏
12. Heroku Concepts: • Buildpacks ⛏ Scripts that transform source code into slugs. • Slugs 🐛 Production artifact made for running in Dynos. • Dynos 🦖 Lightweight-containers. Vary by type, RAM and feature$
13. • Language versions: ◦ Erlang ◦ Elixir ◦ Node.js * • App config: ◦ SSL ◦ Websocket Buildpacks 󰟲 -> ⛏ -> 🐛 -> 🦖
14. ...Coming up in Phoenix 1.6 🥳 https://github.com/evanw/esbuild

19. Strategy #2 Container Image 🐳
20. Actual work WHYYYY IS MY ENV NOT BEING SET !?!?!!11

22. • Language versions • Build Tools • Build Processes • Architectures • Exact replica of a release • Portability Containers
23. 1- Test your strategy by running a local release 🏠🚀 2- DO NOT let your Dockerfile turn into 💩 Takeaways for using containers:
24. “Single stage” Multi-stage
