Made a backup AMI:

        /           snap-07040b6b386d6acb2
        /server     snap-0286ef83451f54f8a

The system had been up for 21 days.

Installed 23 update packages, 20 for security. including
a new kernel.
    yum update

Stopped Discourse.
    cd ~/discourse/image
    ./launcher stop app

The system came up promptly after the reboot.  We are running on
kernel 4.14.273-207.502.amzn2.x86_64.

The Discourse Docker container started automatically after the reboot
and serves HTTP requests normally.

On the Discourse Upgrade manager page:
I upgraded:
    docker_manager      (This upgrade must be run first:
                        the other upgrade buttons are
                        disabled until it has been updated.)

I could not proceed further with update until rebuilding the
Docker image.

Stopped Discourse.
    cd ~/discourse/image
    ./launcher stop app

Rebuilt image.
    cd ~/discourse/image
    git pull
    ./launcher rebuild app

This updates everything pending update.  There is no need to go
back to the update page and update manually.  The application
is automatically restarted.

The Admin page now reports we're running on 2.9.0.beta4.

Verified that spoilers and MathJax are working after being updated.
