In docker inspect, what do "StartedAt" and "FinishedAt" mean?-CodePudding

This is the result of running docker inspect on a running container:

$ docker inspect some_container | jq .[0].State
{
  "Status": "running",
  "Running": true,
  "Paused": false,
  "Restarting": false,
  "OOMKilled": false,
  "Dead": false,
  "Pid": 16086,
  "ExitCode": 0,
  "Error": "",
  "StartedAt": "2021-09-16T02:36:12.036585245Z",
  "FinishedAt": "2021-09-16T04:36:10.87103895 02:00"
}

Nobody was logged into that system at the times listed in the StartedAt and FinishedAt entries, and it doesn't seem like the container was restarted after a crash:

$ docker inspect lxonlinedlservice_rabbitmq_1 | grep RestartCount
        "RestartCount": 0,

What do the StartedAt and FinishedAt entries mean?

CodePudding user response：

To get the exact uptime for a container: docker inspect -f '{{ .State.StartedAt }}' CONTAINER_ID StartedAt: when you started your image or container FinishedAt: when you stopped your image or container (from this answer https://stackoverflow.com/a/28203469/500902)

CodePudding user response：

From github

startedAt - Time at which previous execution of the container started
finishedAt - Time at which the container last terminated

You mentioned crash. Maybe container started after a crash at 2021-09-16T02:36:12.036585245Z and at 2021-09-16T04:36:10.87103895 02:00 there was another crash?

Or, might it me that docker host where the container runs was rebooted?

Suggest also to check that your clock is synced using ntp. Check this docker best practice.
