After updating index.html internally in docker, restarting the nginx service did not find the update.

After running the image with -p 1334:80, the nginx index page is accessed at localhost:1334.
Using bash interactive mode in docker, vim changed the index.html file of nginx, saved and exited, but the effect was not visible after restarting the service. My operation process is as follows:

<code>root@a79dfceda4d9:/usr/sbin# killall nginx        --关掉服务
root@a79dfceda4d9:/usr/sbin# ps -aux|grep nginx
warning: bad ps syntax, perhaps a bogus '-'?

At this time, visit the mapped localhost: 1334. The page has not changed? ? ?
I don’t quite understand, I hope you can give me some advice.

nginx caching is also possible. Generally, parsing it does not take effect immediately.
