---

목적

Jenkins 도커 이미지에 Python 및 Fabric 추가

 

개발 환경 : 우분투(리눅스)

 

Docker File

# https://docs.docker.com/develop/develop-images/dockerfile_best-practices/
FROM jenkins/jenkins:latest

USER root

# Pyhton3.x / fabric install
# Cache busting :: Always combine RUN apt-get update with apt-get install in the same RUN statement
RUN apt-get update && apt-get install -y \
    python3 \
    python3-pip \
# In addition, when you clean up the apt cache by removing /var/lib/apt/lists it reduces the image size, since the apt cache is not stored in a layer. Since the RUN statement starts with apt-get update, the package cache is always refreshed prior to apt-get install.
    && rm -rf /var/lib/apt/lists/*

# Setting sybolic link Pyhton3
RUN ln -s /usr/bin/python3 /usr/bin/python

# Fabric install
RUN pip3 install fabric3 \
    Jinja2 \
