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

```python

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'''

```

```bash

cp /etc/apt/sources.list /etc/apt/sources.list.copy

cat >/etc/apt/sources.list <_ console:

python3 Dockerfile.py

docker images

```

## Alternative uage: 

- install from repo (without pip)

    ```bahs

    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:

    ```python

    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

    

- not required installation

    ```python

    #!/usr/bin/env python

    # -*- coding: utf-8 -*-

    try:

        from pydocker import DockerFile  # pip install -U pydocker

    except ImportError:

        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())

    #

    import sys

    import logging

    logging.getLogger('').setLevel(logging.INFO)

    logging.root.addHandler(logging.StreamHandler(sys.stdout))

    class MyDockerFile(DockerFile):

        """   add here your custom features   """

    #

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

    # ...

    ```

    * Helpful if you need share your Dockerfile.py
