You can also specify absolute dates (like an ISO date for example) or relative like 10 minutes, 30 minutes or 50 minutes.

Similarly to the since option, you can choose to inspect your container logs until a specific date. Note that the logs will be shown given the current date of your system and not the date of the Docker logs. You can also write a date format as long as it is provided in ISO format $ docker logs -since T10:00:00 In order to view Docker logs since a specific date or duration, use the “–since” option with a date or a duration.įor example, to see Docker container logs since 10 minutes, you would write $ docker logs -since 10m When you are inspecting your Docker logs, you often want to limit the output to a given number of lines, not to be flooded with information. $ docker logs įor example, in order to see the Docker logs from a Grafana server started from a Docker image, you would run $ docker logs grafana In order to view and inspect logs on Docker, you have to use the “ docker logs” command with custom options. $ sudo journalctl -u rvice | less View Docker Logs using the logs option $ tail -f -n 1000 /var/log/daemon.log | grep -color dockerĪlternatively, if you are using systemd to manage your services, you can inspect Docker daemon logs with the journalctl command.

AppData/Local : for Windows operating systems Īs a small example, if you installed Docker on Ubuntu or Debian, you would run this command to inspect your Docker daemon logs.

/var/log/upstart/docker.log : for Ubuntu distributions still using upstart.

journalctl -u rvice : for Ubuntu 16.04+ and CentOS 7/8.

/var/log/messages : for RHEL and Oracle Linux.

/var/log/daemon.log : for Debian distributions.

On the other hand, the Docker daemon is also producing some logs for you to inspect.ĭepending on the system you are running Docker on, you will find the Docker daemon logs in different places : However, in most of the cases, using the “logs” command is enough. Similarly, the Apache Web Server will redirect the logs directly to specific file descriptors (/proc/self/fd/1) on your system.

One good example is the NGINX image actually redirecting access and error logs to some specific devices on your Linux system ( /dev/stdout and /dev/stderr). Some particularities may exist depending on the image used.

When they are sent to an external system, you will need to have a logging driver installed for Docker to send its container logs. On Docker, container logs can either be inspected by using the “logs” command or they can be stored on an external system (like Logstash or syslog) in order to be analyzed later on. When it comes to Docker logs, you either want to inspect your container logs or the logs for the Docker daemon.
