What I want to archive:
I want to store the output of the docker build process in a file and see it in the terminal online.
What I try is:
docker-compose build --progress plain myenv | tee myenv.log
What I get is:
I see the output of the build process in the terminal. The file myenv.log is generated, but is empty (size 0 Byte).
What I use:
Ubuntu 22.04 @ WSL version: 2.0.9.0 @ Windows 11
docker-compose version 1.29.2, build unknown
Any Idea?
Based on feedback of @BenjaminGruenbaum and How do I write standard error to a file while using "tee" with a pipe? , my working solution now looks like:
{ { docker-compose build --no-cache --progress plain myenv | (tee std.log); } 2>&1 1>&3 | tee err.log; } 3>&1 1>&2
The file 'std.log' remains empty. The expected log is found in 'err.log'. It's a bit supprising that the docker-compose build output is classified as an error but that's what it is.
