Recommended action: Set CLICKHOUSE_PASSWORD (and optionally CLICKHOUSE_USER/CLICKHOUSE_DB) in the container env and use those credentials; only for throwaway local tests use CLICKHOUSE_SKIP_USER_SETUP=1 (insecure). Option: Configure credentials via env [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. docker run -e CLICKHOUSE_PASSWORD=changeme -p 8123:8123 -p 9000:9000 clickhouse/clickhouse-server 2. Connect with user default + that password Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
