Running a headless server

sergio_101
Hi, all..

I have started looking at the zeroconf scripts, and i think i have most of this figured out.. 

I just have a few questions, to make sure I am doing this correctly.

In order to run the current image headless, should I just do something like:

./pharo Pharo.image —no-quit &

I can load up my project, but how can i get the latest updates to the project?

./pharo Pharo.image update seems like it just updates the VM..

If i run something like this:

./pharo Pharo.image eval --save --no-quit "|server| server := PrintBotServer serveOn: 8080."
a PrintBotServer

I would expect that it would save my image..  but when i hit ^c, and restart it like so:

./pharo Pharo.image

the printbot doesn’t exist anymore. 

any idea how to get this to work correctly?

Thanks!

I think that the --save is executed only on image quit so in this case it is never executed. 
In the end, you can simply in your script do: Smalltalk snapshot: true andQuit: false.

Did you read https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessfulBuild/artifact/book-result/DeploymentWeb/DeployForProduction.html ?

TL;DR

use the config handler to load/update code and save your image

start your server in a script (st handler) or with an expression (eval handler)
