how to save the logs for docker-compose up -d --build - docker

Question

The logs are printed on the console when I do docker-compose up -d --build, how can I have them saved to a file so I can go through the logs?
These logs
0.0s => => transferring dockerfile: 771B
0.0s => [internal] load .dockerignore
0.0s => => transferring context: 2B
0.0s => [internal] load metadata for docker.io/library/python:3.8.12-bullseye
1.5s => [auth] library/python:pull token for registry-1.docker.io
0.0s => [internal] load build context
2.0s => => transferring context: 847.24kB
1.9s => [1/7] FROM docker.io/library/python:3.8.12-bullseye#sha256:b39ab988ac2fa749273cf6fdeb89fb3635850824419dc61
0.0s => => resolve docker.io/library/python:3.8.12-bullseye#sha256:b39ab988ac2fa749273cf6fdeb89fb3635850824419dc61
0.0s => CACHED [2/7] WORKDIR /usr/src/app

Answer 1

Docker already saves the logs in a json file. To find it you can do
docker inspect --format='{{.LogPath}}' [container id]
Or if you just want the outputs of the docker logs function just do this :
docker-compose logs --no-color > logs.txt
For docker-compose up --build, did you try that :
docker-compose up --build &> logs.txt

Answer 2

This can be achieved using docker-compose build and the --progress flag and specifying one of the following options: auto, tty, plain, or quiet (default "auto")
So to persist the logs in your terminal you would build with:
docker-compose build --progress plain
See --help:
 $ docker-compose build --help
Usage: docker compose build [OPTIONS] [SERVICE...]
Build or rebuild services
Options:
--build-arg stringArray Set build-time variables for services.
--no-cache Do not use cache when building the image
--progress string Set type of progress output (auto, tty, plain, quiet) (default "auto")
--pull Always attempt to pull a newer version of the image.
-q, --quiet Don't print anything to STDOUT
--ssh string Set SSH authentications used when building service images. (use
'default' for using your default SSH Agent)
