Syntax
- Für einen Container
- docker logs [OPTIONS] NAME
- Für Services/Tasks eines Docker-Swarms
- docker service logs [OPTIONS] NAME
- Normalerweise werden Standard Output und Standard Error dem Docker-log übergeben.
Beispiel fürs anzeigen verschiedener Docker Informationen
- Containerprotokolle anzeigen
- docker logs nginx
