Upgrade advice - upgrade from aarch64 to ARM64 image

[gwp1]

When on my bare metal RPi with MSR I had a rule that ran every minute to check Internet status via a script in MSR called reactor_inet_check.sh

I've moved to containerized MSR and see in the instructions that this cannot be run from the container.

The script cannot run within the Reactor docker container. If you are using Reactor in a docker container, the script needs to be run by cron or an equivalent facility on the host system (e.g. some systems, like Synology NAS, have separate task managers that may be used to schedule the repeated execution of tasks such as this).

I've put a script on my container host that calls the reator_inet_check.sh script and it isn't erroring... but I still see the internet status within MSR as null.

Before I go diving down the rabbit hole... should this work?

My cronjob on the proxmox host:

The contents of msr_internet_check_caller.sh

OK, first, please don't screen shot text, especially code, logs, and scripts. Learn to use fenced code blocks: put three back-ticks ``` on a line by itself, then follow with the text, the close with another three back-ticks ``` on a line by itself. When formatted, it will look like this:

#!/bin/bash
# Execute the script inside the container
pct exec 101 -- bash -c "cd /home/reactor/reactor;./reactor_inet_check.sh"

The path for the script is suspicious and likely wrong. The reactor_inet_check.sh script has to be run from the Reactor install directory, and doing so would give you a script run path of ./tools/reactor_inet_check.sh. The script is built to run only this way. That's in the script header's instructions.

But also, you are trying to run the script from the Proxmox host, which I guess you can do, but it's unnecessarily hard and makes the configuration dependent on the VMID. I recommend that you run it from Ubuntu. All that's required is this in your Ubuntu root crontab:

    * * * * cd /home/reactor && ./tools/reactor_inet_check.sh

The Ubuntu /var/log/syslog should have information about the success of those runs.

If you're using Reactor access control (i.e. you are configured to required login to access Reactor), you probably will also need to add an ACL to permit the script to use the API.

@toggledbits I know how to tick code - I just didn't think at that hour it would be necessary. Apologies.

Because, YES, trying to configure this from the Proxmox host is devilish, I've added this now to Unbuntu root crontab with:

sudo crontab -e

# MSR script to perform internet check every minute
* * * * * cd /home/reactor/reactor && tools/reactor_inet_check.sh

Looking into the ACL now as I do have Access Control enabled.

EDIT

Taking things in smaller bites... I've renamed users.yaml so Access Control is disabled. Let's start easy

Cron is running. To me, this reads like it's running just fine.

Looking at the Reactor System Entity, however, I still see

reactor_system.internet_ok=null

@toggledbits Most days I'm not very smart... but I'm stubborn.

This is working.

It has kept working thru multiple MSR restarts. (I have not yet tested a container restart.)

I'm not 100% sure why it's working, tbh. I think one more MSR restart cleared the cobwebs and it was suddenly fine. I then added an ACL before putting back Access Control which brings me to...

I also have Access Control back in place and using a hashed pwd (which for some reason eluded me when I tried to enable it previously.)

On this day we're calling it "Two steps back, three forward."

Thanks for your help as always.

@gwp1 said in [SOLVED] reactor_inet_check script... and containers:

It's good to know I'm in good company.

A worthy quality

@gwp1 any chance you could share the script?

TIA

@CatmanV2 reactor_inet_check.sh and it's in your Reactor /tools directory. You don't touch it, just call it.

Then pull the output into a rule
and trigger whatever alerting you'd like.

Oooh thanks!
