How to clean Docker container logs?

Question

I read my Docker container log output using

docker logs -f 

I log lots of data to the log in my node.js app via call

This is not the ideal solution, but until Docker builds in a command to do it, this is a good workaround.

Create a script file docker-clean-logs.sh with this content:

#!/bin/bash

rm $(docker inspect $1 | grep -G '"LogPath": "*"' | sed -e 's/.*"LogPath": "//g' | sed -e 's/",//g');

Grant the execute permission to it:

chmod +x ./docker-clean-logs.sh

Stop the Docker container that you want to clean:

docker stop 

Then run the above script:

./docker-clean-logs.sh 

And finally run your container again:

docker start ...
