How To Modify Docker Logs Size

Docker container logs can grow and consume a large amount of disk. It is recommended to set a limit to the logs files.

To do that, go to /etc/docker/ and set the log-driver and log-opts keys.

The following example sets the log driver to json-file and sets the max-size and max-file options. The total disk used in this case will not exceed 50MB (5*10m):

"log-driver": "json-file",
"log-opts":
{
    "max-size": "10m",
    "max-file": "5"
}

Modify the max-size and max-file as desired.

Note

When installing Shield using OVA, this can be skipped, as these values are already predefined.
