How do the instances synchronise changes to flows, ...?

[andreaswittig]

Your approach looks promising. However, I'm wondering how state gets synchronized between the instances. For example, what happens when a user saves a new version of a flow. How does the other EC2 instance notice that change to make sure it fetches the data again from EFS?

There’s a watcher on the file system that triggers the reload. Does that answer your question?

Thanks a lot for your help, @guysqr. Could you please point me to the code which triggers the reload? I'm trying to understand how this works in detail.

Have a look in the package.json, the start command configures node red to run under nodemon with the appropriate watcher.  Regards Guy On 12 Nov 2019, at 9:18 pm, Andreas Wittig <notifications@github.com> wrote:  Thanks a lot for your help, @guysqr.
