- 5. Problem with Docker Build application configuration runtime Image we want application configuration runtime code, build and test logs, … linters, tests, profilers, … compilers, debuggers, … Image we build x (4..10)
- 6. Docker Builder Pattern • 2 Dockerfiles • 1st for build tools • 2nd for runtime • Drawbacks • 2+ Dockerfiles • Orchestration needed: Bash, make, YAML, …
