cyberstrikeus Ensure the logging level is set to 'info' (Manual)
Profile Applicability
• Level 1 - Docker - Linux
Description
Set Docker daemon log level to info.
Rationale
Setting up an appropriate log level, configures the Docker daemon to log events that you would want to review later. A base log level of info and above would capture all logs except debug logs. Until and unless required, you should not run Docker daemon at debug log level.
Impact
None.
Audit Procedure
To confirm this setting a combination of reviewing the dockerd start-up options and a review of any settings in /etc/docker/daemon.json should be completed.
To review the dockerd startup options, use:
grep "log-level" /etc/docker/daemon.json
Ensure that either the --log-level parameter is not present or if present, then it is set to info.
The contents of /etc/docker/daemon.json should also be reviewed for this setting.
Remediation
Ensure that the Docker daemon configuration file has the following configuration included:
"log-level": "info"
Alternatively, run the Docker daemon as below:
dockerd --log-level="info"
Default Value
By default, Docker daemon is set to log level of info.
