# kubectl logs

kubectl logsSynopsisPrint the logs for a container in a pod or specified resource. If the pod has only one container, the container name is optional.kubectl logs [-f] [-p] (POD | TYPE/NAME) [-c CONTAINER] Examples # Return snapshot logs from pod nginx with only one container kubectl logs nginx # Return snapshot logs from pod nginx, prefixing each line with the source pod and container name kubectl logs nginx --prefix # Return snapshot logs from pod nginx, limiting output to 500 bytes kubectl logs nginx --limit-bytes=500 # Return snapshot logs from pod nginx, waiting up to 20 seconds for it to start running. kubectl logs nginx --pod-running-timeout=20s # Return snapshot logs from pod nginx with multi containers kubectl logs nginx --all-containers=true # Return snapshot logs from all pods in the deployment nginx kubectl logs deployment/nginx --all-pods=true # Return snapshot logs from all containers in pods defined by label app=nginx kubectl logs -l app=nginx --all-containers=true # Return snapshot logs from all pods defined by label app=nginx, limiting concurrent log requests to 10 pods kubectl logs -l app=nginx --max-log-requests=10 # Return snapshot of previous terminated ruby container logs from pod web-1 kubectl logs -p -c ruby web-1 # Begin streaming the logs from pod nginx, continuing even if errors occur kubectl logs nginx -f --ignore-errors=true # Begin streaming the logs of the ruby container in pod web-1 kubectl logs -f -c ruby web-1 # Begin streaming the logs from all containers in pods defined by label app=nginx kubectl logs -f -l app=nginx --all-containers=true # 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 # Show all logs with timestamps from pod nginx starting from August 30, 2024, at 06:00:00 UTC kubectl logs nginx --since-time=2024-08-30T06:00:00Z --timestamps=true # Show logs from a kubelet with an expired serving certificate kubectl logs --insecure-skip-tls-verify-backend nginx # Return snapshot logs from first container of a job named hello kubectl logs job/hello # Return snapshot logs from container nginx-1 of a deployment named nginx kubectl logs deployment/nginx -c nginx-1 Options--all-containersGet all containers' logs in the pod(s).--all-podsGet logs from all pod(s). Sets prefix to true.-c, --container stringPrint the logs of this container-f, --followSpecify if the logs should be streamed.-h, --helphelp for logs--ignore-errorsIf watching / following pod logs, allow for any errors that occur to be non-fatal--insecure-skip-tls-verify-backendSkip verifying the identity of the kubelet that logs are requested from. In theory, an attacker could provide invalid log content back. You might want to use this if your kubelet serving certificates have expired.--limit-bytes intMaximum bytes of logs to return. Defaults to no limit.--max-log-requests int Default: 5Specify maximum number of concurrent logs to follow when using by a selector. Defaults to 5.--pod-running-timeout duration Default: 20sThe length of time (like 5s, 2m, or 3h, higher than zero) to wait until at least one pod is running--prefixPrefix each log line with the log source (pod name and container name)-p, --previousIf true, print the logs for the previous instance of the container in a pod if it exists.-l, --selector stringSelector (label query) to filter on, supports '=', '==', '!=', 'in', 'notin'.(e.g. -l key1=value1,key2=value2,key3 in (value3)). Matching objects must satisfy all of the specified label constraints.--since durationOnly 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 stringOnly return logs after a specific date (RFC3339). Defaults to all logs. Only one of since-time / since may be used.--tail int Default: -1Lines of recent log file to display. Defaults to -1 with no selector, showing all log lines otherwise 10, if a selector is provided.--timestampsInclude timestamps on each line in the log outputParent Options Inherited--as stringUsername to impersonate for the operation. User could be a regular user or a service account in a namespace.--as-group stringsGroup to impersonate for the operation, this flag can be repeated to specify multiple groups.--as-uid stringUID to impersonate for the operation.--cache-dir string Default: "$HOME/.kube/cache"Default cache directory--certificate-authority stringPath to a cert file for the certificate authority--client-certificate stringPath to a client certificate file for TLS--client-key stringPath to a client key file for TLS--cluster stringThe name of the kubeconfig cluster to use--context stringThe name of the kubeconfig context to use--disable-compressionIf true, opt-out of response compression for all requests to the server--insecure-skip-tls-verifyIf true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure--kubeconfig stringPath to the kubeconfig file to use for CLI requests.--kuberc stringPath to the kuberc file to use for preferences. This can be disabled by exporting KUBECTL_KUBERC=false feature gate or turning off the feature KUBERC=off.--match-server-versionRequire server version to match client version-n, --namespace stringIf present, the namespace scope for this CLI request--password stringPassword for basic authentication to the API server--profile string Default: "none"Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)--profile-output string Default: "profile.pprof"Name of the file to write the profile to--request-timeout string Default: "0"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.-s, --server stringThe address and port of the Kubernetes API server--storage-driver-buffer-duration duration Default: 1m0sWrites in the storage driver will be buffered for this duration, and committed to the non memory backends as a single transaction--storage-driver-db string Default: "cadvisor"database name--storage-driver-host string Default: "localhost:8086"database host:port--storage-driver-password string Default: "root"database password--storage-driver-secureuse secure connection with database--storage-driver-table string Default: "stats"table name--storage-driver-user string Default: "root"database username--tls-server-name stringServer name to use for server certificate validation.
