1. Basic Things
FROM indicates what image you are based on.
ENV LANG C.UTF-8 sets what encoding your system will use, something will wrong in Chinese Showing without it
RUN represents every stage you are going, docker will store that stage every time after that line is executed
COPY is like cp
The important thing is: CMD is always the final line of your docker file, that command should be running forever as long as docker container is running
2. The Principle
Put those changeable things in the last, it allows you building docker image quicker
2-3. Buliding
sudo docker build -t yingshaoxo/local_show:1.0 .
3. Debug Stuff
sudo docker logs local_show
sudo docker exec -i -t local_show /bin/bash or sudo docker run --name local_show -it yingshaoxo/local_show:1.0 /bin/bash
4. Come and Push
sudo docker commit local_show yingshaoxo/local_show:1.0
