$ docker run --rm -it -v "$(pwd):/mnt" koalaman/shellcheck-alpine:latest shellcheck --version

⁠Use as a base image

You can create your own image based on this one:

FROM koalaman/shellcheck-alpine:stable
MAINTAINER Your Name <[email protected]>
CMD ["sh"]

Or you can copy the statically linked binary into your own arbitrary image:

FROM alpine:latest
COPY --from=koalaman/shellcheck:stable /bin/shellcheck /bin/

⁠Incorporate into your CI workflow

See koalaman/shellcheck⁠ for more tips.

Note that shellcheck-alpine runs with sh as its entrypoint, so you will need to include shellcheck in your docker run commands. The following commands are equivalent:

docker run --rm -it koalaman/shellcheck:stable --version
docker run --rm -it koalaman/shellcheck-alpine:stable shellcheck --version
