先创建一个目录mosquitto
创建一个Dockerfile文件内容：
FROM eclipse-mosquitto
COPY ./pwfile /etc/mosquitto/pwfile
RUN chmod 777 /etc/mosquitto/pwfile && mosquitto_passwd -U /etc/mosquitto/pwfile
// 创建密码：
mosquitto_passwd [ -c | -D ] passwordfile username
mosquitto_passwd -b passwordfile username password
mosquitto_passwd -U passwordfile
创建pwfile 内容：
user:pwd
创建mosquitto.conf
pid_file /var/run/mosquitto.pid
persistence true
persistence_location /mosquitto/data
allow_anonymous false
password_file /etc/mosquitto/pwfile
port 1883
listener 11880
protocol websockets
创建一个启动的脚本 start.sh
docker run --name m2m_mosquitto -t -d -v $PWD/mosquitto.conf:/mosquitto/config/mosquitto.conf -p 32011:1883 -p 32012:11880 m2m-mosquitto
