Description

Since upgrading the docker package today I'm getting this at the start of every docker build command, even with -q for quiet:

2025/02/20 13:17:35 in: []string{}
2025/02/20 13:17:35 Parsed entitlements: []

Expected behaviour

Not have left over debug outputs

Actual behaviour

Unexepcted debug outputs

Configuration

FROM alpine:latest

Run docker buildx build -q .

Build logs

With -q you get the following two lines:

2025/02/20 13:36:55 in: []string{}
2025/02/20 13:36:55 Parsed entitlements: []

Without -q you get the above plus:

[ardasevinc]

it's a harmless accidental debug right?

[jreichman]

it's a harmless accidental debug right?

I rely on the quiet output to capture the SHA to reference later, rather than tag the image. This output does break those processes. There might be a better way of doing it, but this is an example of it breaking something.

Not exactly what I do, but something like this used to work, but doesn't now

TAG=$(docker build -f Dockerfile -q .)

docker run --rm -it "$TAG"

It's nice when you don't want to (or can't) make assumptions about what tags you can use for temporary builds and don't want to collide or overwrite other tags.
