I assume you haven’t read the dockerhub image description?

Most likely the problem is caused by your config.yml. Please share your config.yml.

Update: you already raised an issue in the github project: docker-registry-ui container restarting. panic: yaml: line 83: did not find expected key · Issue #74 · Quiq/registry-ui · GitHub

May I ask why it made sense from your perspective to open a topic here for something that was already addressed in the github issue?

Use quiq/registry-ui,
not quiq/docker-registry-ui.
