docker log overlay

The Docker overlay network driver is designed to provide a scalable and flexible networking solution for Docker containers running on multiple hosts. The overlay network driver allows Docker containers to communicate with each other seamlessly, regardless of the host they are running on.

When using the overlay network driver, Docker logs are also handled differently than with other drivers. Docker logs from containers running on an overlay network are not automatically sent to the host's syslog daemon, as they are with the default bridge network driver. Instead, Docker logs are sent directly to the Docker daemon on the host where the container is running.

To view Docker logs for containers running on an overlay network, you can use the `docker logs` command followed by the container ID or name. For example, to view the logs for a container named `my-container` running on an overlay network named `my-overlay-network`, you would use the following command:

docker logs my-container

If you want to view the logs for a container running on a specific host in an overlay network, you can use the `docker logs` command with the `--tail` and `--follow` options, followed by the container ID or name and the hostname. For example, to view the logs for a container named `my-container` running on a host named `my-host` in an overlay network named `my-overlay-network`, you would use the following command:

docker logs --tail 100 --follow my-container@my-host

This command will display the last 100 lines of logs for the container and continue to follow new logs as they are generated.
