Minimal .gitlab-ci.yml illustrating the issue

---
uname:
  image: registry.fedoraproject.org/fedora:34
  script:
    - uname -a

Expected behavior No public url available.

Host information Fedora 34 gitlab-ci-local 4.26.0

Additional context I can’t get e.g. gitlab-runner exec docker uname to work, as ‘gitlab-runner’ requires (seems to?) a “served” git repo to pull from (i.e. it ignores CWD, saying “fatal: ‘FOO’ does not appear to be a git repository. fatal: Could not read from remote repository”).

Providing the actual upstream repo URL (using --clone-url) doesn’t work due to cert issues (and neither --docker-tlsverify=no nor variables: GIT_SSL_NO_VERIFY: "true" in ‘.gitlabc-ci.yml’ make any difference), which I’m pretty sure I have no hope of figuring out… which is why I’m here 😃
