Pydocker
为人类提供简易生成器停靠文件
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 : )
安装
# sudo apt-get install python-setuptools && sudo easy_install pip
pip install -U pydocker
使用
# Dockerfile.py

可选语言：
从repo安装（不带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
无需任何安装：

- 如果您只需要构建img，会很有帮助
