Reactor-Editor / Reactor-ui-Status Errors

[Talisker]

I have made good progress setting up a new Raspberry PI 4 with the latest OS (64bit) and latest Reactor images in Docker. However I am not able to copy my configuraiton files (.yml) and reactor reactions over. I am not yet that confident with linux commands, so I have tired to drag and drop the files from a USB drive to the working folders in my new Raspberry PI. I am getting a popup in the GUI stating 'The file operation was completed with errors.' and Errors occured: "rule-xxxxxx.json: Error opening file "/home/pi/reactor/....................................json":Permission denied.

I suspect it's something to do with permissions?

Is there an easier way to copy my configuration over??

Where are the files currently?
What user are you logging on as when you're copying the files?

There's sort of a million ways to solve this.
You can SCP them over
SFTP them over
Copy them as the correct user (which is the fundamental issue.

So what user are you working as and what user owns the /home/pi/reactor folder?

ls -l /home/pi

Will be a good start

Do you have SSH access to the Pi?

I suspect the files on the QNAP have root as the owner. That often happens with docker containers, and if you're just logged in as the pi user trying to copy the files, you'll get those messages. Drag and drop isn't going to get you there. I don't have a QNAP NAS, but if you can ssh into it, do that (log in as yourself). Then...

• Bring yourself up to root sudo su -.
• Navigate (using cd) to the directory above your config, storage, and logs on the QNAP NAS.
• Make an archive file: tar cvf ../reactorconfig.tar .
  This will create the archive file in the directory above your current directory.
• Copy the archive file to the Pi (e.g. into /home/pi)
• Log in on the Pi as pi
• Become root on the Pi: sudo su -
• Go to the directory you created for the Reactor work files (using cd)
• Untar the archive file: tar xvf /home/pi/reactorconfig.tar
• Make your future life easier by making pi the owner of the files (esp. the config files): chown -R pi .
• Exit the root privilege level: exit (you are now user pi again)
• Try starting the docker container (using docker-compose is highly recommended, see install instructions).

Thanks for the prompt responses guys. I might have to concede on this one and start my reactions again!

On another note. I have installed / configured docker-compose (or at least I thought I had). I don't seem to be able to use it to stop reactor:

pi@raspberrypi:~ $ docker stop reactor

I should probably leave this to @toggledbits but what does

su docker stop reactor

do?

[Talisker]

pi@raspberrypi:~/reactor $ su docker stop reactor
su: user docker does not exist or the user entry does not contain all the required fields

[CatmanV2]

Oh sorry!

sudo docker stop reactor

DOH

[Talisker]

@catmanv2 I tried that thanks and it works:

sudo docker stop reactor #stops reactor
sudo service docker restart #starts reactor

Cheers!

@toggledbits thanks for the methodology. I manged to copy the files from a usb stick to the relevant folders using the sudo cp command. Feeling pretty pleased as I am now up an running on my raspberry pi.

[toggledbits]

Just add the pi user to the docker group on the Pi, and you won't have to sudo to use the docker or docker-compose commands.

# Run this command as user `pi`:
sudo usermod -a -G docker pi

Going forward, you should do everything related to the process (container) via docker-compose. You should rarely need or use the docker command itself.

[Talisker]

@toggledbits something is not working quite right with my docker install (docker-compose). Not sure where to start!

[toggledbits]

Can you post your compose file? Also, I assume you ran the docker-compose command while in the same directory as the compose file? Did you start it with docker-compose? If not, you're probably going to get errors like this trying to stop it with docker-compose... the two commands are not interchangeable (for start/stop).

Sorry @toggledbits . I tied it again after a good break and it appears to work fine. I honestly don't know what was going wrong but things seem to now be in order:

pi@raspberrypi:~ $ cd reactor
pi@raspberrypi:~/reactor $ ls
config docker-compose.yml logs storage
pi@raspberrypi:~/reactor $ docker-compose down
Stopping reactor ... done
Removing reactor ... done
Removing network reactor_default
pi@raspberrypi:~/reactor $ docker-compose pull
