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
