### Explanation on the commands in build.sh
My steps for deploying English on the server.
My steps for deploying English on a Ubuntu server.
- ssh to ubuntu@118.*.*.118
- cd to /home/lanhui/englishpal2/EnglishPal
- cd to `/home/lanhui/englishpal2/EnglishPal`
- Stop all docker service: `sudo service docker restart`. If you know the docker container ID, then the above command is an overkill. Use the following command instead: `sudo docker stop ContainerID`. You could get all container IDs with the following command: `sudo docker ps`
- Rebuild container. Run the following command to rebuild a docker image after the code gets updated: `sudo docker build -t englishpal .`
- Rebuild container. Run the following command to rebuild a docker image each time after the source code gets updated: `sudo docker build -t englishpal .`
- Run the application: `sudo docker run -d -p 90:80 -v /home/lanhui/englishpal2/EnglishPal/app/static/frequency:/app/static/frequency -t englishpal`. If you use `sudo docker run -d -p 90:80 -t englishpal`, data will be lost after terminating the program.
- Run the application: `sudo docker run -d -p 90:80 -v /home/lanhui/englishpal2/EnglishPal/app/static/frequency:/app/static/frequency -t englishpal`. If you use `sudo docker run -d -p 90:80 -t englishpal`, data will be lost after terminating the program. If you want to automatically restart the docker image after each system reboot, add the option `--restart=always` after `docker run`.
- Save space: `sudo docker system prune -a -f`
- Save disk space: `sudo docker system prune -a -f`
`build.sh` contains all the above commands. Run "sudo ./build.sh" to rebuild and start the web application.
