Configure docker so that it doesn't use up all the space on the SD card

[nolim1t]

Issue

After a while the SD card gets used up with logfiles.

Solution

Set a configuration value to stop the docker log files from taking up all the space, or disabling log files if it is possible as we already have logging (is this possible @noaho ? )

Temporary fix

Restart docker-compose every week or two.

Where its an issue

On the food4thought box and my own box,

Another temporary fix which stops logs completely (so you have to use individual app logs)

echo "" > $(docker inspect --format='{{.LogPath}}' compose_btcbox_1)
echo "" > $(docker inspect --format='{{.LogPath}}' compose_btcbox_1)
echo "" > $(docker inspect --format='{{.LogPath}}' compose_invoicerbox_1)

Cool that's a good idea as a temporary workaround

[AnotherDroog]

What if it's not the logs?

[nolim1t]

it seems the main culprit is whats in containers.

[nolim1t]

btw that above workaround doesn't stop the box logs, it actually just wipes it temporarily.

So we don't have to restart docker-compose

We just iterate through all the containers (which I think we should include nginx and iotwifi), and pass

echo "" > $(docker inspect --format='{{.LogPath}}' containername)

and it will just reset the containers log files

This ties in to #76

[nolim1t]

Created issue within noma project to make this a utility for now, as configuring docker and reproducing this issue takes some time to reconfirm that it still is an issue.

Alternatively, can remap logs to /dev/null

I also doubt this is the logs. To clean up past docker images, builds, etc, use docker system prune command.

[nolim1t]

Perhaps we could put docker system prune --force on a crontab ?
