# Notes
A kubectl plugin for watching resources and generating diffs.
If you want to watch multiple objects, and some of them are namespace-scoped, then they must be in the same namespace.
# Prerequisite
This tool need `diff` utility for files comparison, so make sure `diffutils` has already been installed.
> GNU Diffutils: https://www.gnu.org/software/diffutils/
If you want a colorful output, you can install `colordiff` wrapper for `diff` tool.
> Colordiff: https://www.colordiff.org/
# Install
1. You can download the release package manually:
> https://github.com/leopoldxx/kube-watch-diff/releases
2. Or, install using the installation script:
> curl -sfL https://raw.githubusercontent.com/leopoldxx/kube-watch-diff/master/install.sh | sh -s -- -b /usr/bin
# Usage
You could use it like the examples below（install as kubectl plugin):
```shell
# watch a namespace scoped resource(use without kubectl)
kubectl-watch pod pod1
```
```shell
# watch a clusters scoped resource
kubectl watch node node1
```
```shell
# watch multiple resources in a same namespace
kubectl watch nodes/node1 pods/pod1 pods/pod2
```
```shell
# watch multiple resources using a label selector
kubectl watch pods -l far=bar
kubectl watch deployment,rs -l far=bar
```
```shell
# watch all pods on the same node
kubectl watch pods --field-selector spec.nodeName=192.168.1.1
```
```shell
# watch 'all' category resource using label selector
kubectl watch all -l far=bar -n test-ns
```
```shell
# watch all masters
kubectl watch node -l node-role.kubernetes.io/master=""
```
```shell
# watch all nodes, and record the diffs into a file
kubectl-watch nodes --all 2>/dev/null | tee nodes.diff
```
