Updating QNAP Docker Container to 2.0.18

[chip]

Hi All,
I have been running MinimServer 2.0.16 Update 195 and MinimStreamer 2.0.8 in a Docker Container on my QNAP TVS-463 for the last several months without any problems.
I happened to click the Show Updates in the About dialogue today and see a new dialogue telling me I should update to MinimServer 2.0.18 for continued support and updates.

When I clicked "For more information, see this section." I see the following twice:
MinimServer 2.0.18 for Linux
This is a bug-fix release for MinimServer 2. It was released on 7th April 2021.
Bug fixes
Fix "cannot stat '/home/pi/.minimserver/bin/setup'" error after uninstall and install

I searched the MinimServer Help files and forum for instructions on updating a Docker Container but only find the installation instructions which finally brings me to my question?

Can I update the existing Docker Container or do I need to remove the existing Container and create a new Container?
