skaffold build -q tag does not match tagger settings

[Blackclaws]

Expected behavior

Running

skaffold build -q

should output the actual built tag in the tag field.

Actual behavior

tag contains the sha256 id of the image

Information

• Skaffold version: v2.0.3
• Operating system: Ubuntu 22.04
• Installed via: curl
• Contents of skaffold.yaml:

apiVersion: skaffold/v3
kind: Config
metadata:
  name: test
build:
  artifacts:
    - image: "target"
  tagPolicy:
    envTemplate:
      template: "{{.VERSION}}"

• Content of Dockerfile:

FROM alpine@sha256:8914eb54f968791faf6a8638949e480fef81e697984fba772b3976835194c6d4

Steps to reproduce the behavior

1. VERSION=1 skaffold build

Generating tags...
 - target -> target:1

2. VERSION=1 skaffold build -q --dry-run

{"builds":[{"imageName":"target","tag":"target:1"}]}

3. VERSION=1 skaffold build -q

{"builds":[{"imageName":"target","tag":"target:49176f190c7e9cdb51ac85ab6c6d5e4512352218190cd69b08e6fd803ffbf3da"}]}

Seeing as the docs state:

  # Quietly build artifacts and output the image names as json
  skaffold build -q > build_result.json

I would have expected that -q outputs the tag that it actually created even if not dry running.

Fun fact, if you also include --push then the result is correct, though the sha256 digest is appended:

> VERSION=1 skaffold build --default-repo REDACTED -q --push
{"builds":[{"imageName":"target","tag":"REDACTED/target:1@sha256:c0d488a800e4127c334ad20d61d7bc21b4097540327217dfab52262adc02380c"}]}

I'm experiencing the same issue. I tried version 1.39.2 and the same behavior exists there as well.

Over a year later this is still a problem unless push is set to true.

Run into same problem here, too.
The tagPolicy configuration is ignored.
