LogConfiguration

The log configuration specification for the container.

This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run . By default, containers use the same logging driver that the Docker daemon uses; however the container may use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

The following should be noted when specifying a log configuration for your containers:

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the valid values below). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks using the EC2 launch type, the Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide.
For tasks using the Fargate launch type, because you do not have access to the underlying infrastructure your tasks are hosted on, any additional software needed will have to be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.

logDriver

The log driver to use for the container. The valid values listed earlier are log drivers that the Amazon ECS container agent can communicate with by default.

For tasks using the Fargate launch type, the supported log drivers are awslogs, splunk, and awsfirelens.

For tasks using the EC2 launch type, the supported log drivers are awslogs, fluentd, gelf, json-file, journald, logentries,syslog, splunk, and awsfirelens.

For more information about using the awslogs log driver, see Using the awslogs Log Driver in the Amazon Elastic Container Service Developer Guide.

For more information about using the awsfirelens log driver, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide.

Note

If you have a custom driver that is not listed, you can fork the Amazon ECS container agent project that is available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we do not currently provide support for running modified copies of this software.

Type: String

Required: Yes

options

The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

Type: String to string map

Required: No

secretOptions

The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

Type: Array of Secret objects
