Now you know where the container logs are stored, and you can continue to troubleshoot and debug any issues that come up. docker psĬONTAINER_ID IMAGE COMMAND CREATED STATUS PORTS NAMESĬf74b6fce535 foo_image "node app.js" X min ago Up X min 3000/tcp foo_app The container_id is located in the first column. If you’re not sure which id is related to which container, you can run the docker ps command to list all running containers. The here is the id of the running container. You find these JSON log files in the /var/lib/docker/containers/ directory on a Linux Docker host. Each log file contains information about only one container and is in JSON format. These logs are emitted from output streams, annotated with the log origin, either stdout or stderr, and a timestamp.
#Docker syslog name drivers
There are several different log drivers you can use except for the default json-file, like syslog, journald, fluentd, or logagent. Here’s a more elaborate explanation from the Docker docs.
#Docker syslog name driver
What’s a logging driver?Ī logging driver is a mechanism for getting info from your running containers. Containers are stateless, and the logs are stored on the Docker host in JSON files by default. You see, by default, Docker containers emit logs to the stdout and stderr output streams. Where Are Docker Container Logs Stored by Default?

Let me elaborate on why with the long answer below. The short answer, that will satisfy your needs in the vast majority of cases, is: /var/lib/docker/containers//-json.logįrom here you need to ship logs to a central location, and enable log rotation for your Docker containers.

The file pattern will contain the same number of columns, if a value is missing it will be empty. The request-out log file pattern contains a list of pipe ( "|" ) separated values. The time in ms for the request to process. The size of the user request in bytes, for example, the size of an uploaded file. -1 if unknown. 1 if unknown (for example, chunked encoding). The size of the server response in bytes, for example, the size of downloaded file. The requesting user's username or "anonymous" when accessed anonymously. The IP address of the remote caller (ipv4 or ipv6). The date and time the request was completed and entered into the log file, in UTC time with the standard format: . Note: If not provided by the client, the ' Request Content-Length' value is initialised as " -1". The request log file pattern contains a list of pipe ( "|" ) separated values. The fully qualified class name and line number printing this log entry. Trace id is used to identify a request across services
