制作系统基础环境镜像 [x] 基于Ubuntu制作镜像资源
>⚠️[注意事项]:由于拉取的Docker hub 的大多数镜像都没有安装Vim ss 等等资源,而且大部分镜像资源是官方镜像库更新资源后安装极其不方便,因此自己构建一个通用镜像尤为重要。
基于Ubuntu制作镜像资源
1.在宿主机创建文件目录:/docker/ubuntu/environment mkdir -p /docker/ubuntu/environment
2.安装的资源如下: java shh 等 vim psmisc rsync supervisor netcat
3.替换阿里云的镜像资源 bionic版本: deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
xenial版本: deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
>⚠️[注意事项]:具体的依据自己的选择的系统版本进行替换
4.编写Dockerfile 文件: ######################################## #Setting source to base images ######################################## ARG IMAGE_VERSION=bionic-20191202 FROM ubuntu:${IMAGE_VERSION} ######################################## #Setting images author ######################################## MAINTAINER marklin<marklin1992@outlook.com> ######################################## #Setting and update datasource ######################################## WORKDIR /etc/apt RUN mv sources.list sources-backup.list RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse' >>sources.list RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse' >>sources.list RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse' >>sources.list RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse' >>sources.list RUN apt-get update ######################################## #Setting install software tools ######################################## RUN apt-get install vim openssh-server openssh-client openjdk-8-jdk ssh git dirmngr netcat psmisc rsync supervisor --assume-yes RUN apt-get clean && \ rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/* ######################################## #Setting sytem path ######################################## RUN rm -rf /root/.bashrc ADD .bashrc /root RUN chmod -R 777 /root/.bashrc ######################################## #Setting JAVA_HOME path ######################################## ENV JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 ENV PATH=${PATH}:${JAVA_HOME}/bin ######################################## #Setting ssh start ######################################## RUN mkdir /var/run/sshd RUN echo 'root:root' |chpasswd RUN sed -ri 's/^#?PermitRootLogin\s+.*/PermitRootLogin yes/' /etc/ssh/sshd_config RUN sed -ri 's/UsePAM yes/#UsePAM yes/g' /etc/ssh/sshd_config RUN mkdir /root/.ssh ######################################## #Setting hadoop start ######################################## WORKDIR / EXPOSE 22 CMD ["/usr/sbin/sshd", "-D"]
