Docker + GitHub Actions

A multi-stage Dockerfile and a pipeline that builds, tests and deploys on green.

Intermediate20 min on the clock9 graded checks · 100 pointsDocker + Deploy SprintPro
Graded by reading your code against the checklist below.

What you build

  • Build in the SDK image, ship only the output in the runtime image
  • Run as a non-root user and declare the port
  • Add a HEALTHCHECK the platform can poll
  • Check out, set up the toolchain, build and run the tests on every push
  • Deploy to Azure only from main, only after the build passes

Done means

docker build produces a small runtime image, and a push to main deploys after tests pass.
