A bit too late to the party

I wrote a bash script to automate it. What the script does is

1. pull the latest image
2. stop the current container
3. remove the current contianer
4. create a new container with latest image

All your data is on local hard drive so you don't have to backup.

#!/bin/bash

if [ `id -u` -ne 0 ]
        then echo "[ERROR] Run in sudo!"
        exit
fi

read -p "note password: " accessword
if [ -z "${accessword}" ]; then
        accessword="DefaultPasswd"
fi
printf "\nYour password is:\n ${accessword}]\n\n"

echo "[pull] pulling latest image"
docker pull b3log/siyuan > /dev/null
echo "[pull] done!"
echo "[stop] stopping container"
docker stop siyuan > /dev/null
echo "[stop] done!"
echo "[rm] removing container"
docker rm siyuan > /dev/null
echo "[rm] done!"
echo "[start] starting container"
docker run -d -v /srv/siyuan:/srv/siyuan -p 8088:6806 --name siyuan -u 1000:1000 -t b3log/siyuan --workspace=/path/to/siyuan/root --accessAuthCode="$accessword" > /dev/null
echo "[start] done!"
