title: kbcli cluster logs Access cluster log file. ``` kbcli cluster logs NAME [flags] ``` ``` kbcli cluster logs mycluster kbcli cluster logs mycluster --tail=20 kbcli cluster logs --instance my-instance-0 kbcli cluster logs mycluster --instance my-instance-0 kbcli cluster logs mycluster --instance my-instance-0 -c my-container kbcli cluster logs mycluster --file-type=slow kbcli cluster logs -f mycluster --file-type=slow kbcli cluster logs mycluster --instance my-instance-0 --file-path=/var/log/yum.log kbcli cluster logs mycluster --instance my-instance-0 -c my-container --file-path=/var/log/yum.log ``` ``` -c, --container string Container name. --file-path string Log-file path. File path has a priority over file-type. When file-path and file-type are unset, output stdout/stderr of target container. --file-type string Log-file type. List them with list-logs cmd. When file-path and file-type are unset, output stdout/stderr of target container. -f, --follow Specify if the logs should be streamed. -h, --help help for logs --ignore-errors If watching / following pod logs, allow for any errors that occur to be non-fatal. Only take effect for stdout&stderr. -i, --instance string Instance name. --limit-bytes int Maximum bytes of logs to return. --prefix Prefix each log line with the log source (pod name and container name). Only take effect for stdout&stderr. -p, --previous If true, print the logs for the previous instance of the container in a pod if it exists. Only take effect for stdout&stderr. --since duration 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. Only take effect for stdout&stderr. --since-time string Only return logs after a specific date (RFC3339). Defaults to all logs. Only one of since-time / since may be used.

This will make your HTTPS connections insecure --kubeconfig string Path to the kubeconfig file to use for CLI requests. --match-server-version Require server version to match client version -n, --namespace string If present, the namespace scope for this CLI request --request-timeout string The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests. (default "0") -s, --server string The address and port of the Kubernetes API server --tls-server-name string Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used --token string Bearer token for authentication to the API server --user string The name of the kubeconfig user to use ``` - Cluster command.
