Docker可以做同样的事吗
Image1: Linux
Image2A: Python2.7 (FROM Image1)
Image2B: Python3.6 (FROM Image1)
Image3: install application (FROM Image2A or FROM Image2B)
Image4A: Linux>Python2.7>applciation (FROM Image3 with same parameters that depend python2.7)
Image4B: Linux>Python3.6>applciation (FROM Image3 with same parameters that depend python3.6)
如果不可能，建议如何计划。对我来说关键是我有 可交换的中间层，并希望有简单的方法来构建最后一层。
