Save time and typing by templating your Dockerfile builds. The templates can be use to create reusable extensions.
pip install:
Note: if you don't want to be prompted for the defaults that I have set, like name, email or want to modify the
url for the release_image, you can add a .cookiecutterrc file to your home directory.

The Dockerfile.j2 template in the cc-docker project can be used as a reuseable template and applied to
multiple Docker images. To apply the Dockerfile.j2 to multiple base images, it's as easy as setting a few
environment variables.
For instance, let's say I wanted to apply a bootstrap to a set of dockerfiles. This bootstrap might container packages for my developer environment or possible settings for the image to work correctly on my corporate network.
In my bootstrap folder created by cc-docker:
#!/bin/bash
IMAGES=(caffe cntk mxnet tensorflow torch)
REPO=nvcr.io/nvida
VERSION=17.03
for IMAGE in $IMAGES; do
BASE_IMAGE=$REPO/$IMAGE:$VERSION \
IMAGE_NAME=my-$IMAGE:$VERSION \
RELEASE_IMAGE=registry.local/$IMAGE:$VERSION \
make release
done
# Clean up images from bootstrap system
# Doing this after ensure that the base layers do not get downloaded repeatedly.
for IMAGE in $IMAGES; do
BASE_IMAGE=$REPO/$IMAGE:$VERSION \
IMAGE_NAME=my-$IMAGE:$VERSION \
RELEASE_IMAGE=registry.local/$IMAGE:$VERSION \
make distclean
done
