In Docker, you can usedocker logsCommand to view the container's log. Here are some common uses:
Basic usage
docker logs <container_id_or_name>: View the standard output (stdout) and standard error (stderr) logs of the specified container.
View logs in real time
docker logs -f <container_id_or_name>: Real-time tracking log output (similar totail -f）。
View the recent logs
docker logs --tail <number_of_lines> <container_id_or_name>: View the log of the most recent specified number of rows. For example, view the most recent 100-line log:
docker logs --tail 100 <container_id_or_name>
View logs for specific time ranges
docker logs --since <timestamp> <container_id_or_name>: View logs after the specified time point. The timestamp can be in date format or relative time (e.g.1hIndicates the past hour).
docker logs --since "2023-05-01T00:00:00" <container_id_or_name> docker logs --since 1h <container_id_or_name>
docker logs --until <timestamp> <container_id_or_name>: View the log before the specified time point.
docker logs --until "2023-05-01T00:00:00" <container_id_or_name> docker logs --until 1h <container_id_or_name>
Combination use
-
docker logs -f --tail 100 <container_id_or_name>: Track the logs in real time and display only the most recent 100 rows. -
docker logs --since 1h --until 30m <container_id_or_name>: View logs from the past hour to the past 30 minutes.
Example
Suppose you have a container ID ofabc123, you can use the following command to view its log:
View all logs:
docker logs abc123
View the log in real time:
docker logs -f abc123
View the most recent 50-line log:
docker logs --tail 50 abc123
Check out the logs for the past hour:
docker logs --since 1h abc123
View logs from a specific point in time:
docker logs --since "2023-05-01T00:00:00" abc123
With these commands, you can easily view and track the logs of Docker containers, helping you debug and monitor.
