Description:

jocker 0.0.5

jocker generates
Dockerfiles from
Jinja2 based template files. You
can optionally build an image from the generated file and even more
optionally, push it to a hub.

Requirements

must be run sudo-ically due to Docker’s sudo requirement!
Python 2.6/2.7 (errr… NO TESTS YET? what a n00b!)
Docker

Installation
pip install jocker

Testing
Disclaimer in broken english: This like 5 hours project. Tests yet, No.
Hold as test being wroten. Yes.

Usage
jocker -h
Script to run jokcer via command line

Usage:
jocker [--varsfile=<path> --templatefile=<path> --outputfile=<path> --dockerconfig=<path> --dryrun -v]
[--build=<string>|--push=<string>]
jocker --version

Options:
-h --help Show this screen.
-f --varsfile=<path> Path to varsfile (if omitted, will assume "vars.py")
-t --templatefile=<path> Path to Dockerfile template
-o --outputfile=<path> Path to output Dockerfile (if omitted, will assume "Dockerfile")
-c --dockerconfig=<path> Path to yaml file containing docker-py configuration
-d --dryrun Whether to actually generate.. or just dryrun
-b --build=<string> Image Repository and Tag to build
-p --push=<string> Image Repository and Tag to push to (will target --build)
-v --verbose a LOT of output (Note: should be used carefully..)
--version Display current version of jocker and exit

Generating

A varsfile containing a dict named VARS should be supplied
(if omitted, will default to vars.py).
A templatefile should Jinja2-ly correspond with the variables in
the aforementioned VARS dict (if omitted, will default to
Dockerfile.template)
An outputfile should be given (if omitted, will default to
Dockerfile)

Dryrun
If Dryrun is specified, the output of the generated template will be
printed. No file will be created.

Build and Push
You can let jocker know that after the Dockerfile was generated, you’d
like to either Build a Docker image and optionally Push it to your
chosen repository.
Note that for this to work you must be logged in to Docker Hub or your
private images repo from your shell.
Also note that for either of these features to work you MUST be sudo’d
as it’s a prerequisite of Docker.
Also also note that you can’t specify both –build and –push as –push
triggers a build process anyway.

docker-py configuration for build and push
A dockerconfig yaml file can be specified which includes something
like this:
client:
base_url: 'unix://var/run/docker.sock'
version: '1.14'
timeout: 10
build:
quiet: false
nocache: false
rm: false
stream: false
timeout:
encoding:
This is the configuration for the docker client and for the build
process as mentioned in https://github.com/docker/docker-py.

Vagrant
The Vagrantfile supplied (which I haven’t finished yet.. will let you
know once it’s ready) will loadz a vbox machine, install docker and
jocker on it, generate a docker image from a template and run a
container based on the image in a daemonized mode to demonstrate the
KRAZIE RAW POWER of jocker (and docker.. I guess wink)
