Usage notes¶

The current role must have the MONITOR privilege on the service to access the container logs.
The function returns a container log as a string.
When using the --follow option for real-time log streaming, the --num-lines and --previous-logs options are not supported.

Examples¶

The following example displays the last three lines of the echo_service logs:

snow spcs service logs echo_service --container-name echo --instance-id 0 --num-lines 3

Copy

18.94.31 - - [22/Nov/2024 09:16:47] "GET /healthcheck HTTP/1.1" 200 -
18.94.31 - - [22/Nov/2024 09:16:52] "GET /healthcheck HTTP/1.1" 200 -
18.94.31 - - [22/Nov/2024 09:16:57] "GET /healthcheck HTTP/1.1" 200 -

This example streams the logs for the echo_service service and updates them every 10 seconds:

snow spcs service logs echo_service --container-name echo --instance-id 0 --follow --follow-interval 10

Copy

The following example displays the log entries since 9:30 UTC, 21 Nov 2024:

snow spcs service logs echo_service --container-name echo --instance-id 0 --since 2024-11-21T09:30:00Z

Copy

The following example retrieves logs from the last-terminated container:

snow spcs service logs example_job_service --container-name main --instance-id 0 --previous-logs
