Docker includes multiple logging mechanisms to help youget information from running containers and services.These mechanisms are called logging drivers. Each Docker daemon has a defaultlogging driver, which each container uses unless you configure it to use adifferent logging driver, or “log-driver” for short.
As a default, Docker uses the json-file logging driver, whichcaches container logs as JSON internally. In addition to using the logging driversincluded with Docker, you can also implement and use logging driver plugins.
Tip: use the “local” logging driver to prevent disk-exhaustion
By default, no log-rotation is performed. As a result, log-files stored by thedefault json-file logging driver logging driver can cause a significant amount of disk space to be used for containers that generate muchoutput, which can lead to disk space exhaustion.
Docker keeps the json-file logging driver (without log-rotation) as a defaultto remain backward compatibility with older versions of Docker, and for situationswhere Docker is used as runtime for Kubernetes.
For other situations, the “local” logging driver is recommended as it performslog-rotation by default, and uses a more efficient file format. Refer to theConfigure the default logging driversection below to learn how to configure the “local” logging driver as a default,and the local file logging driver page for more details about the“local” logging driver.
Configure the default logging driver
To configure the Docker daemon to default to a specific logging driver, set thevalue of log-driver to the name of the logging driver in the daemon.jsonconfiguration file. Refer to the “daemon configuration file” section in thedockerd reference manualfor details.
The default logging driver is json-file. The following example sets the defaultlogging driver to the local log driver:
If the logging driver has configurable options, you can set them in thedaemon.json file as a JSON object with the key log-opts. The followingexample sets two configurable options on the json-file logging driver:
Restart Docker for the changes to take effect for newly created containers.Existing containers do not use the new logging configuration.
Note
log-opts configuration options in the daemon.json configuration file mustbe provided as strings. Boolean and numeric values (such as the value formax-file in the example above) must therefore be enclosed in quotes (').
If you do not specify a logging driver, the default is json-file.To find the current default logging driver for the Docker daemon, rundocker info and search for Logging Driver. You can use the followingcommand on Linux, macOS, or PowerShell on Windows:
Note
Changing the default logging driver or logging driver options in the daemonconfiguration only affects containers that are created after the configurationis changed. Existing containers retain the logging driver options that wereused when they were created. To update the logging driver for a container, thecontainer has to be re-created with the desired options.Refer to the configure the logging driver for a containersection below to learn how to find the logging-driver configuration of acontainer.
Configure the logging driver for a container
When you start a container, you can configure it to use a different loggingdriver than the Docker daemon’s default, using the --log-driver flag. If thelogging driver has configurable options, you can set them using one or moreinstances of the --log-opt <NAME>=<VALUE> flag. Even if the container uses thedefault logging driver, it can use different configurable options.
The following example starts an Alpine container with the none logging driver.
To find the current logging driver for a running container, if the daemonis using the json-file logging driver, run the following docker inspectcommand, substituting the container name or ID for <CONTAINER>:

Configure the delivery mode of log messages from container to log driver
Docker provides two modes for delivering messages from the container to the logdriver:
- (default) direct, blocking delivery from container to driver
- non-blocking delivery that stores log messages in an intermediate per-containerring buffer for consumption by driver
The non-blocking message delivery mode prevents applications from blocking dueto logging back pressure. Applications are likely to fail in unexpected ways whenSTDERR or STDOUT streams block.
Warning
Spm Micro Driver Tool
When the buffer is full and a new message is enqueued, the oldest message inmemory is dropped. Dropping messages is often preferred to blocking thelog-writing process of an application.
The mode log option controls whether to use the blocking (default) ornon-blocking message delivery.
The max-buffer-size log option controls the size of the ring buffer used forintermediate message storage when mode is set to non-blocking. max-buffer-sizedefaults to 1 megabyte.
The following example starts an Alpine container with log output in non-blockingmode and a 4 megabyte buffer:
Use environment variables or labels with logging drivers
Some logging drivers add the value of a container’s --env|-e or --labelflags to the container’s logs. This example starts a container using the Dockerdaemon’s default logging driver (let’s assume json-file) but sets theenvironment variable os=ubuntu.
If the logging driver supports it, this adds additional fields to the loggingoutput. The following output is generated by the json-file logging driver:
Supported logging drivers
The following logging drivers are supported. See the link to each driver’sdocumentation for its configurable options, if applicable. If you are usinglogging driver plugins, you maysee more options.
| Driver | Description |
|---|---|
none | No logs are available for the container and docker logs does not return any output. |
local | Logs are stored in a custom format designed for minimal overhead. |
json-file | The logs are formatted as JSON. The default logging driver for Docker. |
syslog | Writes logging messages to the syslog facility. The syslog daemon must be running on the host machine. |
journald | Writes log messages to journald. The journald daemon must be running on the host machine. |
gelf | Writes log messages to a Graylog Extended Log Format (GELF) endpoint such as Graylog or Logstash. |
fluentd | Writes log messages to fluentd (forward input). The fluentd daemon must be running on the host machine. |
awslogs | Writes log messages to Amazon CloudWatch Logs. |
splunk | Writes log messages to splunk using the HTTP Event Collector. |
etwlogs | Writes log messages as Event Tracing for Windows (ETW) events. Only available on Windows platforms. |
gcplogs | Writes log messages to Google Cloud Platform (GCP) Logging. |
logentries | Writes log messages to Rapid7 Logentries. |
Note
When using Docker Engine 19.03 or older, the docker logs commandis only functional for the local, json-file and journald logging drivers.Docker 20.10 and up introduces “dual logging”, which uses a local buffer thatallows you to use the docker logs command for any logging driver. Refer toreading logs when using remote logging drivers for details.
Limitations of logging drivers
- Reading log information requires decompressing rotated log files, which causesa temporary increase in disk usage (until the log entries from the rotatedfiles are read) and an increased CPU usage while decompressing.
- The capacity of the host storage where the Docker data directory residesdetermines the maximum size of the log file information.
-'Freedom in Mobility' as #Freedom of Space, #Smart Delivery, #Autonomous Driving, etc. Connecting the mobility with people through 'Electric Hyperconnectivity' (X-by-Wire, SPM Module)
Mando explains the details of 'Freedom' they define, especially in terms of freedom in mobility such as 'Space Freedom', 'Smart Delivery', etc. Also, a future automotive solution, where a vehicle seamlessly communicates with a driver via an integrated module of 'x-by-Wire' technology including Mando's BbW (Brake-by-Wire) and SbW (Steer-by-Wire) all connected by the electric hyper-connectivity, will be introduced. The Smart Personal Mobility Module (SPM Module) connects people with micro-mobility. The SPM Module, as the world's first chainless pedal-assisted system, provides the freedom to the design of micro mobility.
'Space Freedom' enables freedom in in-cabin activities beyond the architectural limits of a vehicle. In fully autonomous driving mode, space freedom is especially needed the most because a driver has all this time available for activities other than driving. With Mando's SbW (Steer-by-Wire), which has been awarded with CES 2021 Innovation Award Honoree, auto stow function is enabled which allows the steering wheel to be stowed away when not in use and taken out again for use when needed. That is how SbW realizes the true freedom in Space. Car makers can now enjoy the freedom from their architectural limits of vehicle design. 'By-wire' technology of Mando can also be applied to the brake system, which is called BbW (Brake by Wire). It is composed of 4 units of EMB (Electro Mechanical Brake), mounted on '4-corner module (4 wheels)', 'E-Brake-Pedal (Electronic brake pedal)', and DCU (Domain Control Unit). Brake-by-Wire eliminates ESC (Electronic Stability Control), booster (brake boost), parking cable, engine oil tube, etc., and obviously it is operated only by pure electric signal. 'E-Brake-Pedal' also has 'auto stow' function to put away the pedal when not in use and take it out again when needed. It definitely provides much more free space in leg room for drivers. BbW does not use brake oil, thus it is easy to maintain and eco-friendly as well. Mando, as the only company in the world to develop/manufacture brake, steering, suspension, and ADAS, has been accelerating the development of 'In-Wheel-Motor (drive part in electric vehicle)' and 'ECM (Electric-Corner-Module)' based on the experience of designing 'SbW' and 'BbW'.
'SPM Module (Smart Personal Mobility Module)' introduced by Mando is a chainless pedal-assisted electric drive system. Micro mobility manufacturers are the target customers. SPM Module enables the novel concepts of 2, 3 or 4-wheels and it also provides various lifestyles in numbers of scenes in our daily life. SPM Module, with cutting-edge technology such as AI, IoT, Cloud, etc., is aimed for the delivery market first, and is planned to start making its way to the European market this year.
The autonomous driving technology of Mando has its priority on the safety of drivers. Mando, which develops / manufactures from detection sensor (camera, radar, etc.) to main controller (DCU: Domain control Unit) and control software, introduces the dual safety (redundant) control technology based on the 'High Performance DCU' at this CES. This dual safety device is also applied to the brake and steering (driving system) component.
