• 0

  Common

  Most of the 4 edited versions we read keep these.

• 13

  Distinctive

  This author's own choices. Worth a look.

• 4

  Very specific

  Tied to their project's names, files or tools. Probably skip.

1. Distinctive:

   Use a builder stage for compilation, dependency installation, and other build-time operations

   line 10
2. Distinctive:

   Use a separate runtime stage that only includes what's needed to run the application

   line 11
3. Very specific:

   Use meaningful stage names with the AS keyword (e.g., FROM node:18 AS builder)

   line 13
4. Distinctive:

   Place stages in logical order: dependencies → build → test → runtime

   line 14
5. Distinctive:

   Start with official, minimal base images when possible

   line 18
6. Distinctive:

   Consider distroless images for runtime stages where appropriate

   line 20
7. Distinctive:

   Use Alpine-based images for smaller footprints when compatible with your application

   line 21
8. Distinctive:

   Ensure the runtime image has the minimal necessary dependencies

   line 22
9. Distinctive:

   Place commands that change frequently (like code changes) after commands that change less frequently (like dependency installation)

   line 27
10. Very specific:

    Use .dockerignore to prevent unnecessary files from being included in the build context

    line 28
11. Very specific:

    Consider using COPY --chown to set permissions in one step

    line 30
12. Very specific:

    Avoid running containers as root - use USER instruction to specify a non-root user

    line 34
13. Distinctive:

    Remove build tools and unnecessary packages from the final image

    line 35
14. Distinctive:

    Use multi-stage builds to avoid including build secrets in the final image

    line 38
15. Distinctive:

    Use build arguments for configuration that might change between environments

    line 42
16. Distinctive:

    Consider parallelization in build steps when possible

    line 44
17. Distinctive:

    Use appropriate healthchecks for the application type with the HEALTHCHECK instruction

    line 46

“Common” is measured: kept by at least 6 in 10 of the 4 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

  How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

  How we pick theseFiles found in the same public projects as a version of this one, more often than they turn up anywhere else. Each project counts once, large collections count for less, and this file's own repository is left out.
