## kubectl logs

Print the logs for a container in a pod.

### Synopsis


Print the logs for a container in a pod. If the pod has only one container, the container name is optional.

```
kubectl logs [-f] [-p] POD [-c CONTAINER]
```

### Examples

```
# Return snapshot logs from pod nginx with only one container
kubectl logs nginx

# Return snapshot of previous terminated ruby container logs from pod web-1
kubectl logs -p -c ruby web-1

# Begin streaming the logs of the ruby container in pod web-1
kubectl logs -f -c ruby web-1

# Display only the most recent 20 lines of output in pod nginx
kubectl logs --tail=20 nginx

# Show all logs from pod nginx written in the last hour
kubectl logs --since=1h nginx
```

### Options

```
  -c, --container="": Print the logs of this container
  -f, --follow[=false]: Specify if the logs should be streamed.
      --include-extended-apis[=true]: If true, include definitions of new APIs via calls to the API server. [default true]
      --limit-bytes=0: Maximum bytes of logs to return. Defaults to no limit.
  -p, --previous[=false]: If true, print the logs for the previous instance of the container in a pod if it exists.
      --since=0: Only return logs newer than a relative duration like 5s, 2m, or 3h. Defaults to all logs. Only one of since-time / since may be used.
      --since-time="": Only return logs after a specific date (RFC3339). Defaults to all logs. Only one of since-time / since may be used.
      --tail=-1: Lines of recent log file to display. Defaults to -1, showing all log lines.
