Docker support logging to format or different platforms, such as [1]
Configuration is done at docker container start time with command docker run -it --log-drive LOG_METHOD CONTAINER_ID
Sending logs to syslog or logstash
docker run --log-driver=syslog --log-opt syslog-address=tcp://<logstash-system-ip>:5000 hello-world
- Check method configured in a running container:
docker inspect -f '{{.HostConfig.LogConfig.Type}}' CONTAINER_ID
docker inspect -f '{{.HostConfig.LogConfig}}' CONTAINER_ID
docker inspect <container_id|container_name> | grep -A 5 LogConfig
"LogConfig": {
"Type": "syslog"
"Config": {}
}
- View logs
docker logs CONTAINER_NAME_OR_ID(Docker Community Engine only support: local, json-file and journald)docker logs CONTAINER_NAME_OR_ID2>&1 | grep "STRING_TO_SEARCH" (You will need to redirect outputs to be able to grep output)[3]- See https://docs.docker.com/config/containers/logging/ for more information
