README
# kubectl-watch
[English](./README.md)
一个可以监听 kubernetes 资源的变更信息的 kubectl 插件。其中变更的内容通过使用 [delta](https://github.com/dandavison/delta) 或 [difftastic](https://github.com/Wilfred/difftastic) 工具提供漂亮的终端界面展示。

## 安装说明
### [推荐] 方式一：使用 Docker 镜像
1. 您需要在环境里预先安装好 Docker，参考 [官网](https://docs.docker.com/engine/install/)；或者安装 containerd，参考 [安装教程](https://github.com/containerd/containerd/blob/main/docs/getting-started.md#installing-containerd) 和 [nerdctl](https://github.com/containerd/nerdctl) 命令行工具。
2. 拷贝 script 目录下的 kubectl-watch 脚本到环境的 $PATH 其中的一个目录下，比如 `/usr/local/bin`。
```bash
cp script/kubectl-watch /usr/local/bin/
chmod +x /usr/local/bin/kubectl-watch
```
### 方式二：从 [release assets](https://github.com/imuxin/kubectl-watch/releases) 下载可执行制品。
### 方式三：使用 [Cargo](https://crates.io/crates/kubectl-watch)进行源码编译安装。
```bash
cargo install kubectl-watch --locked
```
## Cmd 帮助
```bash
USAGE:
kubectl-watch [OPTIONS] [ARGS]
ARGS:
Support resource 'plural', 'kind' and 'shortname'
Resource name, optional
OPTIONS:
-A, --all If present, list the requested object(s) across all namespaces
--diff-tool Diff tool to analyze delta changes [default: delta] [possible values: delta, difft]
--export A path, where all watched resources will be strored
-h, --help Print help information
--include-managed-fields Set ture to show managed fields delta changes
-l, --selector Selector (label query) to filter on, supports '=', '==', and '!='.(e.g. -l key1=value1,key2=value2)
-n, --namespace If present, the namespace scope for this CLI request
-s, --skip-delta Skip show delta changes view
--use-tls Use tls to request api-server
-V, --version Print version information
```
## 参考实例
监听所有命名空间下的 deployment 资源
```bash
kubectl-watch deployment -A
```
监听某个命名空间下的 depoyment 资源
```bash
kubectl-watch deployment -n {namespace}
```
监听某个命名空间下的某个 depoyment 资源
```bash
kubectl-watch deployment -n {namespace} {name}
```
追加 `--skip-delta` 选项，仅监听变动资源，同 `kubectl get -w`
```bash
kubectl-watch {resource} --delta
```
追加 `--diff-tool difft` 选项来使用 `difftastic` 工具显示变化内容
```bash
kubectl-watch {resource} --diff-tool difft
```
追加 `--export "/to/your/path"` 选项，导出监听的资源到本地存储
```bash
kubectl-watch {resource} --export "/to/your/path"
```
`managed-fields` 默认是不进行比对的, 追加 `--include-managed-fields` 选项，展示 managed fields 的变化
```bash
kubectl-watch {resource} -include-managed-fields
```
