Windows11下Docker使用记录（二）

Docker中container，image，dockerfile
以及docker hub的关系如图所示，详细可见上一篇帖子。
本文主要记录Dockerfile相关。

1. 常用指令

2. Dockerfile示例

FROM ubuntu:16.04

# install ROS kinetic
RUN apt-get update \
    && apt-get -y install curl \
    && sh -c 'echo "deb http://packages.ros.org/ros/ubuntu xenial main" > /etc/apt/sources.list.d/ros-latest.list' \
    && curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | apt-key add - \
    && apt-get update \
    && apt-get -y install ros-kinetic-desktop-full \
    && echo "source /opt/ros/kinetic/setup.bash" >> /etc/bash.bashrc \
    && /bin/bash -c '. /etc/bash.bashrc' \
    && apt-get -y install python-rosdep python-rosinstall python-rosinstall-generator python-wstool build-essential \
    && rosdep init \
    && rosdep update 
# create catkin_ws
RUN mkdir -p ~/catkin_ws/src \
    && cd ~/catkin_ws \
    # # ...
    # # do what you need to do for example git clone something into ~/catkin_ws/src
    # # ...
    && /bin/bash -c '. /opt/ros/kinetic/setup.bash; cd ~/catkin_ws; catkin_make; . ./devel/setup.bash'
