ksonnet 是一个基于jsonnet的快速简化kubernetes yaml 配置的工具，可以实现配置的复用
同时也包含一个registry 的概念，可以实现可复用组件的分发，同时支持helm
环境准备
- 安装cli
使用mac 系统
brew install ksonnet/tap/ks- 包含的命令
ks --help----Usage: ?ks [flags] ?ks [command]Available Commands: ?apply Apply local Kubernetes manifests (components) to remote clusters ?component Manage ksonnet components ?delete Remove component-specified Kubernetes resources from remote clusters ?diff Compare manifests, based on environment or location (local or remote) ?env Manage ksonnet environments ?generate Use the specified prototype to generate a component manifest ?help Help about any command ?import Import manifest ?init Initialize a ksonnet application ?module Manage ksonnet modules ?param Manage ksonnet parameters for components and environments ?pkg Manage packages and dependencies for the current ksonnet application ?prototype Instantiate, inspect, and get examples for ksonnet prototypes ?registry Manage registries for current project ?show Show expanded manifests for a specific environment. ?upgrade Upgrade ks configuration ?validate Check generated component manifests against the server‘s API ?version Print version information for this ksonnet binaryFlags: ?????--dir string Ksonnet application root to use; Defaults to CWD (default "/Users/dalong") ?-h, --help help for ks ?????--tls-skip-verify Skip verification of TLS server certificates ?-v, --verbose count Increase verbosity. May be given multiple times.Use "ks [command] --help" for more information about a command.基本使用
- init 应用
ks init dalongdemo- 生成的项目结构
- 定于部署的组件
以下操作只是演示,我们可以使用命令行工具，快速生成应用的组件
ks generate deployed-service dalongdemo ??--image dalongrong/appdemo:1.0 ??--type ClusterIP如下：
- 查看生成的yaml ?
从下面的可以看出还是很方便的
ks show default---apiVersion: v1kind: Servicemetadata: ?labels: ???ksonnet.io/component: dalongdemo ?name: dalongdemospec: ?ports: ?- port: 80 ???targetPort: 80 ?selector: ???app: dalongdemo ?type: ClusterIP---apiVersion: apps/v1beta2kind: Deploymentmetadata: ?labels: ???ksonnet.io/component: dalongdemo ?name: dalongdemospec: ?replicas: 1 ?selector: ???matchLabels: ?????app: dalongdemo ?template: ???metadata: ?????labels: ???????app: dalongdemo ???spec: ?????containers: ?????- image: dalongrong/appdemo:1.0 ???????name: dalongdemo ???????ports: ???????- containerPort: 80- helm 的集成
添加仓库
ks registry add helm-stable https://kubernetes-charts.storage.googleapis.com添加charts
ks pkg install helm-stable/wordpress效果
说明
ksonnet 基于jsonet 的开发模型让yaml文件的编写可以实现模块，共享，我们可以像写代码一样写
yaml 文件了，同时可以实现复用
