Dockerfile创建了一个文件，但它不在那里

Question

RUN echo 'source /opt/ros/kinetic/setup.bash' >> /home/ubuntu/.bashrc
RUN echo 'source /home/ubuntu/catkin_ws/devel/setup.bash' >> /home/ubuntu/.bashrc

RUN /bin/bash -c "echo 'export HOME=/home/ubuntu' >> /root/.bashrc && source /root/.bashrc"
RUN pwd
RUN cd ~ && pwd
RUN cat /home/ubuntu/.bashrc
RUN mkdir -p ~/catkin_ws/src
RUN source /home/ubuntu/.bashrc && \
  cd ~/catkin_ws/src && \
  /opt/ros/kinetic/bin/catkin_init_workspace && \
  cd ~/catkin_ws && \
  catkin_make

当然，这是我的错误，但我看不到它和我的理解的差距。谢谢！

source不是有效命令，它是bash内置命令。

它不是告诉您文件/home/ubuntu/.bashrc而是告诉您source不是命令

只需将RUN参数放在sh脚本中，以#！/bin/bash正确启动。然后只需使用copy将sh复制到容器中，并使用run运行它。

COPY script.sh /
RUN ["chmod", "+x", "/script.sh"]
RUN /script.sh

RUN /bin/bash -c "source ...."
