# Purpose: install Debian packages in a Docker image
|
||||
#
|
||||
# Usage: deb2docker [options] packages
|
||||
# -B do NOT build the image (default is to build)
|
||||
# -c CMD command to run in the container (default to '/bin/bash')
|
||||
# -f FROM indicate which distribution is to be used (default to debian:stable)
|
||||
# -h show this help
|
||||
# -n NAME name of the image (default to package list)
|
||||
# -o DIR use given directory for the build (default in /tmp)
|
||||
# -p PRE execute the given script during the container build (before packages install)
|
||||
# -s POST execute the given script during the container build (after packages install)
|
||||
# -v show package version
|
||||
# The package list can be any Debian package, as well as local .deb
|
||||
#
|
||||
# Example: 'deb2docker -o /tmp/xeyes x11-apps' then '/tmp/xeyes/start xeyes'
|
||||
|
||||
# build: docker build --rm Dockerfile
|
||||
# run: docker run --rm -it NAME
|
||||
# clean: docker rmi NAME
