I need to use the tail ... --pid=PID option in my docker container that is based on Alpine image in order to I can kill the running background tail process automatically.
Unfortunately the BusyBox tail that is available in the Alpine Docker image doesn't support this feature.
I am trying to find a material that describes the process how to replace it but no luck.
I don't want to use another base image because the image size is important.
Is it possible to switch to the GNU tail somehow?
This is the solution:
apk add --no-cache bash coreutils Before:
tail --version tail: unrecognized option: version BusyBox v1.35.0 (2022-11-19 10:13:10 UTC) multi-call binary. After:
tail --version tail (GNU coreutils) 9.1 Copyright (C) 2022 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later <https://gnu.org/licenses/gpl.html>.
