Dielee / volvo2mqtt

I'm on v1.8.27, running it in docker not connected to HA (i run OpenHab).
I want to have linux rsyslog read the log file and notify my syslog server with errors, and today i do that by binding the volvo2mqtt.log log file that resides in the main directory. That log file just wrapped around (> 100kb in size) and i ran into docker issues mapping that 2nd file.
Any chance you can move the log file to a local directory (like "log" in the main directory) i can bind to instead of binding to the file?

Permission issue with the bind mount?

I'd rather avoid:

volumes:
  - type: bind
    source: ./logs/volvo2mqtt.log
    target: /volvoAAOS2mqtt/volvo2mqtt.log
  - type: bind
    source: ./logs/volvo2mqtt.log.1
    target: /volvoAAOS2mqtt/volvo2mqtt.log.1
  - type: bind
    source: ./logs/volvo2mqtt.log.2
    target: /volvoAAOS2mqtt/volvo2mqtt.log.2
  - type: bind
    source: ./logs/volvo2mqtt.log.3
    target: /volvoAAOS2mqtt/volvo2mqtt.log.3

....

is it a permissions issue with access to the directory you've mapped volvo2mqtt.log too?

No, logging to volvo2mqtt.log works.
It was some time since i got the error, so can't remember exactly what error i got. But it was when volvo2mqtt.log was full (100k) and was gonna be moved to volvo2mqtt.log.1 and a new volvo2mqtt.log created.
So then i thought: "why do i have to map each file, can't they be put in a log directory instead?"

can the docker container create a new file or does it not have write permissions?

what does your docker-compose.yml look?

  - type: bind
    source: ./logs/volvo2mqtt.log
    target: /volvoAAOS2mqtt/volvo2mqtt.log
  - type: bind
    source: ./logs/volvo2mqtt.log.1
    target: /volvoAAOS2mqtt/volvo2mqtt.log.1
  - type: bind
    source: ./logs/volvo2mqtt.log.2
    target: /volvoAAOS2mqtt/volvo2mqtt.log.2
  - type: bind
    source: ./logs/volvo2mqtt.log.3
    target: /volvoAAOS2mqtt/volvo2mqtt.log.3

But i'd rather have this:

volumes:
  - type: bind
    source: ./logs/
    target: /volvoAAOS2mqtt/logs/

i.e. i don't want to single-bind a log file. This ticket isn't about write permission, it's about log dir structure.

Looks like if you run this as a Home Assistant addon you do get the log in /logs

volvo2mqtt/src/util.py

Line 44 in 907440b

log_location = "/addons/volvo2mqtt/log/volvo2mqtt.log"

I'm not sure why ypu can't just do?

 - type: bind
    source: ./logs/volvo2mqtt.log
    target: /volvoAAOS2mqtt/

I do not run HomeAssistant (see first post).

Never bound a container file to a host directory. But no matter if it works or not, it will still force me to bind each and every log file in the docker-compose file.

I'm not sure why it would require you to create every file if the container had the correct host permissions but I don't feel that I have anything else to add.

Good luck.

Please bind every single file. It will work and you don't even need five versions from the log, in my opinion.

Move log file(s) to log-directory?
