log2ram about iotstack HOT 5 CLOSED

log2ram replaces the /var/log folder with a ramdrive then syncs those changes to disk on a schedule. This reduces the total writes to the sd card.

The containers don't log to /var/log, they log to their own internal logs

from iotstack.

Because each container has its own log that writes to disk inside their respective container it may be worthwhile to map them securely into /var/log to get full benefit of log2ram

That's what i was asking for, Thanks. I just getting into Docker, may i find out how to map the logs into /var/log

from iotstack.

Each container will differ as to where they store their logs. I used the script "./services/nodered/terminal.sh" to open the shell for nodered. Doing a "ls /var/log" inside nodered shows that its "standard" log is empty. I would assume that the standard log would be empty and containers would do minimal logging.

First you would need to make a subfolder in /var/log that you want to share. Don't directly map your /var/log because you don't want to unnecessarily expose your sensitive data to a container.

If you do find the log for a container you can edit the docker-compose.yml file and under the volumes add

volumes:

• /var/log/MYLOG:/path/to/log/inside/container

Thank you!
