How to disable podman output logs in the console

[Kovsonq]

We are trying to migrate our console app from docker to podman, but can't disable podman outputs, like:

Under the hood, we are using the docker-java client to communicate with the podman socket and we use console as UI and don't want this output here.
How to disable podman output (or redirect it into the file)?

[mheon]

Can you clarify the architecture more here? You're using the Podman HTTP API, but how - are you launching it via systemd with podman.socket? Is this output coming from the Podman service directly?

1 - I run podman.socket using this command: podman system service --time 0 &

2 - I think that output comes from API. I found note bellow and it means I need to change systemd log-level:
Note: The default systemd unit files (system and user) change the log-level option to info from error. This change provides additional information on each API call.

I changed systemd log level to warning:

# systemd-analyze get-log-level
warning

But it doesn't disable the output.

[Kovsonq]

The output is disabled after applying this command:
sudo systemctl enable --now podman.socket

[rhatdan]

What version of Podman you are using?
Did you pass in the --quiet flag?

[Kovsonq]

1 The answer is above.
2 We use docker-java client to pull and push images and don't use --quiet flag.

[rhatdan]

I think we fixed a bunch of issues to fix these messages showing up on the server side. Could you try it with podman 3.4?

[laurensV]

I am still having the same problem not being able to disable the output from the API with podman version 4.6.2...

We are running the podman service with

podman system service --time 0 tcp:0.0.0.0:8080&

And when making Docker API calls to this podman server to for example pull an image, it will print logs..
