Assemble Image Log For Free

We have to use the 'docker image list command to list Docker images which are locally available on the host on which we are running the command. 'ls' and 'images' are aliases for this command which means we can also run the command 'docker image ls' or 'docker images' to list the Docker images.

The docker service logs command can be used with either the name or ID of a service, or with the ID of a task. If a service is passed, it will display logs for all of the containers in that service. If a task is passed, it will only display logs from that particular task.

Once you start the Docker process with logging, you will also now see the Debug Logs being sent to the console. Now, if you execute any Docker command such as docker images, the Debug information will also be sent to the console.

To filter logs based on time, we can use two flags with the docker-compose logs command: --since and --until . The --since flag is used to view the logs that were generated after a specified time period. In contrast, --until flag is used to view the logs that were produced before a specified time period.

The default logging driver in Docker Compose is the json-file driver. This driver stores logs as JSON files on the host machine where the container is running. However, Docker supports several other logging drivers you can configure in your Docker Compose setup.

You find these JSON log files in the /var/lib/docker/containers/ directory on a Linux Docker host. The <container_id> here is the id of the running container. 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 docker logs command shows information logged by a running container. The docker service logs command shows information logged by all containers participating in a service. The information that is logged and the format of the log depends almost entirely on the container's endpoint command.
