But how to send log messages from hundreds of containers to CloudWatch Logs? Learn how to integrate CloudWatch Logs with ECS (EC2 Container Service). That’s all you need to send log messages from a single container to CloudWatch Logs. log-opt awslogs-group=docker-logs \ # send log messages to log group docker-logsĪlpine \ # use the super small docker image alpineĮcho 'a cloudonaut.io example' # write a cloudonaut.io example to stdout
#DOCKER DAEMON LOGS SETTING DRIVER#
log-driver=awslogs \ # use the log driver awslogs Let’s have a deeper look at the command you used to start your container and send a log message to CloudWatch Logs. The Docker Daemon receives the log messages and uses the logging driver awslogs to forward all log messages to CloudWatch Logs.īack to the example from above.

As shown in the following figure the container writes log messages to stdout and stderr. Use the awslogs logging driver to send logs from your container to CloudWatch Logs without the need of installing any additional log agents.

See Supported logging drivers for details. You can use the following built-in logdrivers: none, json-file, syslog, journald, gelf, fluentd, awslogs, splunk, etwlogs, and gcplogs. But how to transfer a log message from your container to CloudWatch Logs? Docker logging driversĭocker can forward log messages from stdout and stderr to different targets. See CloudWatch Pricing for details.ĬloudWatch Logs offers a REST API to ingest data. CloudWatch logs are priced per amount of ingested data, stored data and transferred data. Stream processes up to 5 MB per second, use multiple streams to scale log data ingestion.Īdditionally, you can use metric filters to monitor incoming log messages.Group a bucket for your log messages, comparable with an S3 bucket.The following figure shows the main elements of CloudWatch Logs: Don’t expect a full-blown solution like Elasticsearch/Kibana, Sumo Logic or Splunk. I do like to use CloudWatch Logs to collect, monitor, and analyze your log messages because of its simplicity. What is CloudWatch Logs?ĬloudWatch Logs is a managed service offered by AWS providing scalable, easy-to-use, and highly available log management. How did your container send a log message to CloudWatch Logs? Read on. Open your CloudWatch Logs group to find your log message as illustrated in the following screenshot.

Start a container with docker run -log-driver=awslogs -log-opt awslogs-group=docker-logs alpine echo 'a cloudonaut.io example'.Launch an EC2 Instance based on the Amazon Linux AMI 2017.03.*, select the IAM role ‘docker-logs’, and attach a security group allowing SSH access.Restrict access to the specific resource and actions instead.
