I want to create a docker image which will run a command similar with tail, how can I redirect the output of this command in the logs of the container?

CodePudding user response：

Everything you output to stdout or stderr will be part of the docker container logs by default.

So for example while this container is running

docker run --rm --name busy busybox sh -c "while true; do echo 'to stdout'; echo 'to stderr' >&2; sleep 1; done"

... you can inspect its logs:

docker logs -f busy

So in short: Just use your tail -f normally.
