How do you change the default logging driver for the docker daemon in Linux?

The correct answer is A. Set the value of log-driver to the name of the logging driver In the daemon.json In /etc/doc. To change the default logging driver for the Docker daemon, you must configure the log-driver setting in the daemon.json file, typically located at /etc/docker/daemon.json.

How do you change the default logging driver for the docker daemon in Linux?

Why each option

To change the default logging driver for the Docker daemon, you must configure the `log-driver` setting in the `daemon.json` file, typically located at `/etc/docker/daemon.json`.

ASet the value of log-driver to the name of the logging driver In the daemon.json In /etc/docCorrect

The `daemon.json` file is the standard configuration file for the Docker daemon in Linux, allowing you to set daemon-wide parameters. To change the default logging driver, you add or modify the `log-driver` key within this JSON file, specifying the desired driver, and then restart the Docker daemon for the changes to take effect.

BUse the -log-driver' flag when you run a container.

The `--log-driver` flag is used when running an *individual container* to override the daemon's default logging driver for that specific container, not to change the daemon's global default.

CAt the command line, type: docker log driver set <driver name>

There is no `docker log driver set` command for configuring the daemon's default logging driver; configuration is primarily done via the `daemon.json` file.

DInstall a logging agent on the Linux host.

Installing a logging agent might be part of a logging *solution*, but it does not directly change the Docker daemon's *default logging driver* configuration.
