QUESTION

Create a systemd service script for multiple module app

Asked 2022-Feb-14 at 01:09

I'm currently writing a python app forking with Pyro4 and flask. In order to start up the app I to need :

Start pyro4 name server
Register my object in the pyro4 name server
Start a flask web app to access pyro4 objects

I would like to do this with a systemd service file. I first though of using ExecStarPre and ExecStarPost for running pyro4 nameserver and flask web app ; but it seems that those fields are not use for long-running commands...

Do I need to make 3 systemd services which I start in a bash script that i call from a 4th systemd service ?

Thx for helping me

You don't need four systemd services; three should do.

pyro-nameserver.service: The Pyro nameserver
mysvc-objects.service: The server for your custom Pyro objects. Use Requires=pyro-nameserver.service and After=pyro-nameserver.service
mysvc.service: The actual Flask webapp. Uses Requires=mysvc-objects.service and After=mysvc-objects.service to ensure that it only tries to start when the nameserver is already up and your objects are registered.

You should never, under any circumstances enable or disable a systemd service from an ExecStartPre or an ExecStartPost.

BTW, one thing that's a little tricky is controlling when systemd considers something to be "up" for purposes of starting the next service in the chain only after that service is done with initialization and ready to use. In a perfect would you build services with Type=notify that use sd_notify("READY=1") to tell systemd when they finished initialization; but if you haven't built that, it's an option to build an ExecStartPost script that waits until the service it's associated with is actually running before it exits.

QUESTION

Using Pyro4 to connect python scripts in separate containers using docker-compose

Asked 2020-Feb-12 at 17:47

The Problem

I want to use Pyro4 for remote procedure calls across multiple containers using docker-compose. Currently, I am just trying to implement a simplified version of the Pyro4 warehouse example that I have setup to run on different machines, instead of the default localhost, since I am using multiple containers.

I can successfully start the Pyro name server in its own container, but in another container I can not publish the Warehouse class and start Pyro's request loop. I am get the error OSError: [Errno 99] Cannot assign requested address.

My attempt and additional information

I am using balena to deploy this to a Raspberry Pi 3 B+, and I have an environment variable (device variable in balena cloud) "PYRO_HOST=pyro-ns" to set the address of the pyro name server.

I see the pyro name server get created

After some help from the balena forums, I was able to successfully get my Pyro example to run.
