kubelogs

It is a bash script that uses your current kubectl context to interactively select namespaces and multiple pods to download logs from. It basically runs kubectl logs in a loop for all containers, redirecting the logs to local files.

Prerequisites

kubelogs relies on whiptail to enable interactive selection.

Whiptail is included by default on Debian. If you are using another OS, make sure to have it installed:

Linux

yum install newt or apt-get install whiptail

MacOS

brew install newt

Installation

Just download the kubelogs file and it's done (download from releases to get stable ones).

Usage

Run kubelogs without any flags to:

• Interactively select a namespace from current context
• Interactively select multiple pods to dump logs from (space bar to check, enter to confirm)
• Input a output dir for log files

Output filenames are created in the form pod_container.log

Use kubelogs --help for all available options and examples.

Skipping some interactive steps

Optionally, the --namespace and --output-dir flags can be used to skip namespace selection and/or typing of output dir (entirely skipping of whiptail is not supported yet).

Inherited flags

Some flags can be passed to kubectl logs that runs under the hood. Use kubelogs --help to see the available ones.

Environment

kubelogs supports the following option values from environment variables:

KUBELOGS_NAMESPACE
KUBELOGS_OUTPUT_DIR
KUBELOGS_TAIL
KUBELOGS_TIMESTAMPS
