기본적으로 Docker 애플리케이션 중 하나는 루트 경로(포트 8080)에서 HTML 문서를 반환하며, 이는 컴퓨터에 연결된 모니터에 표시됩니다. 대부분의 컴퓨터에서는 문제가 없지만 일부 컴퓨터에서는 다음 오류(키오스크 화면에 표시됨)와 함께 화면이 멈춥니다. " Page load error - message corrupt". 때로는 Ansible을 통해 키오스크 설정으로 호스트를 재구성하면 오류가 해결되기도 하고 그렇지 않은 경우도 있습니다. 다시 시작하면 문제가 해결되는 경우도 있지만 매번 그런 것은 아닙니다.
SSH: 서버에 로그인하여 로그( /var/log/syslog)를 확인합니다.많은기록된 오류 수입니다. 일반적으로 말하면 다음과 같습니다.

내가 찾고 있는 것이 무엇인지 확실하지 않다고 말하는 것은 다소 절제된 표현입니다. 실제로 당면한 실제 문제를 분리하고 확대하고 싶지만 지금은 어떻게 해야 할지 잘 모르겠습니다. 추가 로그/구성 정보를 제공할 수 있는 경우 알려주시기 바랍니다. 근본적인 문제를 더 잘 이해하고 싶습니다.
포스팅이 너무 길어서 죄송합니다.. :)
