Using a container-specific logging driver

We have seen that the logging driver can be set globally in the Docker daemon configuration file. But we can also define the logging driver on a container by container basis. In the following example, we are running a busybox container and use the --log-driver parameter to configure the none logging driver:

$ docker container run --name test -it \
--log-driver none \
busybox sh -c 'for N in 1 2 3; do echo "Hello $N"; done'

We should see the following:

Hello 1
Hello 2
Hello 3

Now, let's try to get the logs of the preceding container:

$ docker container logs test

The output is as follows:

Error response from daemon: configured logging driver does not support reading

This is to be expected since the none driver does not produce any logging output. Let's clean up and remove the test container:

$ docker container rm test
