Snapshot summary built from the project's own GitHub metadata — there's no written TopGit review yet. The page will update automatically when a full review is published.
WHY NO REVIEW YET
TopGit writes full reviews for the most-starred, most-requested repositories. This page is a snapshot until then — see the READ ME tab for the original README in full.
docker-slim has been used with Node.js, Python, Ruby, Java, Go, Rust, Elixir and PHP (some app types) running on Ubuntu, Debian, CentOS and Alpine Linux.
Active areas of interest:
Complex Python, Ruby and PHP examples with the popular application servers and Nginx or Apache.
Python, Node.js, Ruby and PHP applications packaged in CentOS-based images.
Examples with fat container images with multiple components/applications/services.
Examples with the most popular process supervisors / init tools.

How to use examples
While DockerSlim is capable of more, at the moment, the majority of the examples illustrate
the image minification procedure using docker-slim build command in its various modes.
A typical example has a README file describing its purpose and basic usage.
Normally, there is also a Makefile with the default target. So, running
make or make default from inside of the example folder would execute the example
for you end-to-end outputting all the used commands on the way.
Most frequently used make targets:
# All example types
make # run example (semi-automatic)
make test-e2e # run the acceptance test suite
make clean # remove all artifacts created by this example
# 'CLI application' example type
make fat-build # build the "fat" version of the image
make fat-run-interactive # run the CLI app using the "fat" image
make slim-build # turn the "fat" image into a "slim" one
make slim-run-interactive # run the CLI app using the "slim" image
make slim-build-from-dockerfile # build the "slim" version of the image using the "fat" Dockerfile
# 'Web Service' example type
make fat-build # build the "fat" version of the image
make fat-run # run the web service using the "fat" image
make fat-run-seccomp # run the "fat" image using generated seccomp profile
make fat-validate # send a request to the running web service
make fat-stop # stop the running web service
make slim-build # turn the "fat" image into a "slim" one
make slim-run # run the web service using the "slim" image
make slim-run-seccomp # run the "slim" image using generated seccomp profile
make slim-validate # send a request to the running web service
make slim-stop # stop the running web service
make slim-build-from-dockerfile # build the "slim" version of the image using the "fat" Dockerfile
make debug-sidecar # run a debug sidecar container with an interactive shell
# 'Docker Compose' example type
make fat-build # build the "fat" version of the image
make fat-run # run the compose file using the "fat" image
make fat-validate # send a request to the running web service
make fat-stop # stop the running web service
make slim-build-compose # turn the "fat" image into a "slim" one using docker-compose file
make slim-run # run the compose file using the "slim" image
make slim-validate # send a request to the running web service
make slim-stop # stop the running web service
