pydocker 1.0.6

pydocker
Easy generator Dockerfile for humans
Let's use power of python for generate dockerfile!

Advantages:
- all features from python: variables, multiline strings, code reuse.
- keep all your code in one file [bash, python, conf, ...]
- generate many docker files from one template [testing, production, ]
- generate sequence [Dockerfile.debian => Dockerfile.python => Dockefile.yourapp, ...]
- or if you not expert in sed, awk - you can use python for modify conf files : )

easy code, easy costomize
Install
# sudo apt-get install python-setuptools && sudo easy_install pip
pip install -U pydocker

Using
# Dockerfile.py
import sys
import logging
import pydocker # github.com/jen-soft/pydocker

logging.getLogger('').setLevel(logging.INFO)
logging.root.addHandler(logging.StreamHandler(sys.stdout))


class DockerFile(pydocker.DockerFile):
""" add here your custom features """


d = DockerFile(base_img='debian:8.2', name='jen-soft/custom-debian:8.2')

d.RUN_bash_script('/opt/set_repo.sh', r'''

d.EXPOSE = 80
d.WORKDIR = '/opt'

# d.ENTRYPOINT = ["/opt/www-data/entrypoint.sh"]
d.CMD = ["python", "--version"]

d.build_img()

# >_ console:

python3 Dockerfile.py
docker images

Alternative uage:


install from repo (without pip)
F=$(python -c "import site; print(site.getsitepackages()[0]+'/pydocker.py')")
sudo wget -v -N raw.githubusercontent.com/jen-soft/pydocker/master/pydocker.py -O $F



without any installation:
try: from urllib.request import urlopen # python-3
except ImportError: from urllib import urlopen # python-2
exec(urlopen('https://raw.githubusercontent.com/jen-soft/pydocker/master/pydocker.py').read())
#
d = DockerFile(base_img='debian:8.2', name='jen-soft/custom-debian:8.2')
# ...


Helpful if you need just build img
