Add Launch Script after Lightsail Creation?

What blueprint are you using?

There are various ways to accomplish a launch script, but it depends on the blueprint.

I'm using MEAN.

Baudot,

Thanks for using Lightsail!

Here is a doc about launch scripts: https://lightsail.aws.amazon.com/ls/docs/en_us/articles/lightsail-how-to-configure-server-additional-data-shell-script

The doc does not explicitly state this but it is important to note that the launch script is only executed on initial launch of the instance, not on every launch. For that reason there is no way to configure the launch script after the instance is initially created.

If you require software to run on every launch of the instance, you should use the os-dependent initialization software such as 'initd' on linux and startup programs on Windows.

I hope this helps!

David - thanks, that worked.

I had to do few more debugging steps to get my script running properly.

In the end the script ended up looking like:

#!/bin/sh

(
cd /full/directory/path/to/my/app
/full/path/to/init_command 1>/var/log/my_app_name/my_app_name.log 2>&1 &
)

...and that did it.
If anyone else runs into a similar hurdle, hopefully this helps.
