docker多段构建nessus镜像

1.构建基础镜像，主要做安装和获取注册号：

FROM ubuntu:16.04

ADD Nessus-8.11.0-debian6_amd64.deb /tmp/Nessus-8.11.0-debian6_amd64.deb

RUN apt-get update -y 
    && apt-get install -y apt-utils tzdata 
    && dpkg -i /tmp/Nessus-8.11.0-debian6_amd64.deb 
    && rm -rf /tmp/* 
    && apt clean 
    && echo "*********************************************" 
    && /opt/nessus/sbin/nessuscli fetch --challenge 
    && echo "*********************************************" 

2.更新插件，根据步骤1中获取到的注册码在Web端进行注册，获取license,并将license添加至镜像中

FROM nessus:base

ADD license /tmp/license
ADD all-2.0.tar.gz /tmp/all-2.0.tar.gz

RUN echo "*******************update-plugin**************************" 
    && /opt/nessus/sbin/nessuscli update /tmp/all-2.0.tar.gz 
    && echo "*******************update-plugin**************************" 
    && rm -rf /tmp/all-2.0.tar.gz 
    && apt clean 
    && echo "*******************register-offline**************************" 
    && /opt/nessus/sbin/nessuscli fetch --register-offline /tmp/license 
    && echo "*******************register-offline**************************" 
EXPOSE 8834
CMD /etc/init.d/nessusd start && tail -f /dev/null
