kubetail

Utility bash script that enables you to follow and grep logs from multiple k8s pods in one stream. It also ships with autocompletion feature which list all available pods in current k8s context that you can use.

Instalation

Download the kubetail script and it's ready to use. For auto completion feature you will also need to download and source completion script. Another way is to clone the github repository and use the script.

Completion

Completion is only available for suggesting arguments (--pods --tail --label --grep) and for values for --pods argument

If you are using bash as main shell run

• cd into completion folder
• run

source ./kubetail.bash

• cd into root folder and run

install ./kubetail /usr/local/bin/kubetail

If you are using zsh as main shell run

• cd into completion folder
• run

autoload bashcompinit
bashcompinit
source ./kubetail.bash

• cd into root folder and run

install ./kubetail /usr/local/bin/kubetail

Usage

• To follow logs by pods name

kubetail --pods <pods name separated by space>

• To follow logs by pods labels

kubetail --label '<pods label in k8s format>'

• To follow logs and grep for info

kubetail [--pods <pods name separated by space>] [--label '<pods label in k8s format>'] --grep <grep expression>

• To follow logs with specified tail

kubetail [--pods <pods name separated by space>] [--label '<pods label in k8s format>'] --tail <last number of rows>

NOTE: when supplying both --pods and --label arguments, only --pods will be considered
