esteban I would like to have a success story for the Pharo web site Could you come up with two paragraphs? And if you have a visual it would be perfect. Remember a success story is that you could do something not that your app become facebook. S.

I've been running a Pharo application since August last year, initially setup with everything inside a Docker swarm (database, reverse proxy and Pharo workers for the UI and REST API).
I wanted to give Docker a try because I thought it was going to be "better". After having some issues with the Swarm networking affecting PostgreSQL connections [1], I ended up having a hybrid that is not the best of both worlds (I wouldn't say it's the worst either).
So my summary is that unless you have several host machines, having a "swarm" is completely overkill and brings more friction than anything else. The plus of docker is that from Gitlab everytime I push a commit to master, a new docker image is created and I can update things smoothly on the server by pulling the image and upgrading the stack service.
"Whenever I have time" I plan to make the reverse proxy external to docker (I currently use traefik as a container), and just keep the database and Pharo workers as docker containers.
As for the stability, I only shut it down for upgrades, but in February I tried with a single VM+image serving everything (just to measure real use) and albeit it was a little slower, it handled everything perfectly [2] without a single hiccup.

Thanks Sanjay - you have reminded me that I have some similar notes somewhere (now located) that did the command line foo to get things running - looking at mine there was quite a big of dance to provide a way to gracefully stop and start the image so that you can easily and automatically redeploy your changes (read: use Github actions or Gitlab CI).
So Iâm curious on whether Docker is now sufficiently stable stable/easy/cheap to make it a viable alternative - and whether that is also cost efficient.
Pablo wrote a recent blog post on running Pharo in Docker using the BA images - https://thepharo.dev/2021/02/24/running-pharo-9-in-docker/ - but while easy on the surface, if anything goes wrong - there seems to be very little debug output to know what has happened (Iâll post separately on this - as Iâm looking at comparing options here).
With Docker options, I notice that dockerize.io (not used, just a quick search) - has a micro plan for $2/m - but is 500mb ram enough (there is a $5 one for 1gm ram).
Or - I stick with DigitalOcean and roll my own like before - and perhaps that has got a bit simpler.
Iâm still curious what the wider community is doing.

Hi Tim
Here are my notes on installing Pharo in a DigitalOcean Ubuntu droplet. I usually go thru a Windows Command prompt box having installed xfec4 in the ubuntu droplet, but the command line connect and graphical remote may be easier for a Linux users. my ssh public key is also in the DO droplet Now the first step for me is a installing Pharo launcher thru command line and then everything is thru graphical interface
Installing and checking Pharo-Launcher, Installing Pharo 8 64 bit from pharo.org (instructions as on Pharo.org) 1. In Windows 10 command prompt connect thru > ssh root@<Droplet-ip> 2. cd 3. curl -o pharo-launcher.zip -L https://files.pharo.org/pharo-launcher/linux64 4. unzip pharo-launcher.zip or thru the GUI-> extract here (pharo-launcher files will be extracted in ./pharo-launcher) Now while connected to the linux graphical interface thru windows remote terminal and in the GUI 5. Create a icon on desktop thru right-click âCreate Launcherâ for pharo-launcher 6. Create pharo images thru pharo-launcher
hope this is of use

Hi everyone - its been a few year since I last hosted a little Pharo web app - and the last time I did, Sven pointed me to DigitalOcean and creating a tiny instance and configuring an Ubuntu server and then copying a pharo image on to that. It recall it wasnât too bad, albeit a bit fiddlyâ¦
Now several years later - I canât recall the exact steps, and vaguely recall there was something about 32bit vs 64bit setup etc - but am wondering if things have advanced a bit and whether its much simpler these days? Iâve seen references to Docker images for Pharo, and am wondering if now that is a prime time way to easily get a small demo application up and running with minimal fuss.
Does anyone have advice - or something to point me to?
Ideally I want to hook something up in Gitlab CI do deploy to this thing automatically (this is where I got to a few years ago - but in picking things back up I am hoping this has all got much simpler).
