在前一篇文章中介绍了Operator Framework，提到了Operator SDK是用来搭建脚手架的重要工具，这篇文章就Operator SDK进行继续展开。

# Operator Framework #

关于Operator和Operator Framework的介绍，可参看：

# 三种开发方式 #

通过使用SDK-CLI，可以使用如下三种方式进行CRD相关的扩展开发，

*  go
 *  Ansible
 *  Helm  
    三者相关所能实现的能力如下所示，使用Helm一般只能实现安装和无缝升级等功能。

# 安装方式 #

## 方式1: 使用brew安装（MacOS） ##

在MacOS下，可以直接使用brew进行安装

> 执行命令：brew install operator-sdk

## 方式2: 二进制文件（github） ##

使用github的release下提供的支持各种OS的相应二进制文件，然后进行权限设定即可。

*  下载文件

# Set the release version variable
    $ RELEASE_VERSION=v1.2.0
    # Linux
    $ curl -LO https://github.com/operator-framework/operator-sdk/releases/download/${RELEASE_VERSION}/operator-sdk-${RELEASE_VERSION}-x86_64-linux-gnu
    $ curl -LO https://github.com/operator-framework/operator-sdk/releases/download/${RELEASE_VERSION}/ansible-operator-${RELEASE_VERSION}-x86_64-linux-gnu

    $ curl -LO https://github.com/operator-framework/operator-sdk/releases/download/${RELEASE_VERSION}/helm-operator-${RELEASE_VERSION}-x86_64-apple-darwin

*  安装设定

# Linux
    $ chmod +x operator-sdk-${RELEASE_VERSION}-x86_64-linux-gnu && sudo mkdir -p /usr/local/bin/ && sudo cp operator-sdk-${RELEASE_VERSION}-x86_64-linux-gnu /usr/local/bin/operator-sdk && rm operator-sdk-${RELEASE_VERSION}-x86_64-linux-gnu
    $ chmod +x ansible-operator-${RELEASE_VERSION}-x86_64-linux-gnu && sudo mkdir -p /usr/local/bin/ && sudo cp ansible-operator-${RELEASE_VERSION}-x86_64-linux-gnu /usr/local/bin/ansible-operator && rm ansible-operator-${RELEASE_VERSION}-x86_64-linux-gnu
    $ chmod +x helm-operator-${RELEASE_VERSION}-x86_64-linux-gnu && sudo mkdir -p /usr/local/bin/ && sudo cp helm-operator-${RELEASE_VERSION}-x86_64-linux-gnu /usr/local/bin/helm-operator && rm helm-operator-${RELEASE_VERSION}-x86_64-linux-gnu
    # macOS
    $ chmod +x operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin && sudo mkdir -p /usr/local/bin/ && sudo cp operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin /usr/local/bin/operator-sdk && rm operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin
    $ chmod +x ansible-operator-${RELEASE_VERSION}-x86_64-apple-darwin && sudo mkdir -p /usr/local/bin/ && sudo cp ansible-operator-${RELEASE_VERSION}-x86_64-apple-darwin /usr/local/bin/ansible-operator && rm ansible-operator-${RELEASE_VERSION}-x86_64-apple-darwin
    $ chmod +x helm-operator-${RELEASE_VERSION}-x86_64-apple-darwin && sudo mkdir -p /usr/local/bin/ && sudo cp helm-operator-${RELEASE_VERSION}-x86_64-apple-darwin /usr/local/bin/helm-operator && rm helm-operator-${RELEASE_VERSION}-x86_64-apple-darwin

## 方式3: 源码安装 ##

$ git clone https://github.com/operator-framework/operator-sdk
    $ cd operator-sdk
    $ git checkout master
    $ make install

# 安装示例 #

这里以方式2为例，在MacOS上安装operator-sdk为例，执行如下命令和日志如下所示

liumiaocn:~ liumiao$ RELEASE_VERSION=v1.2.0
    liumiaocn:~ liumiao$ curl -LO https://github.com/operator-framework/operator-sdk/releases/download/${RELEASE_VERSION}/operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin

                                     Dload  Upload   Total   Spent    Left  Speed
    100   665  100   665    0     0    360      0  0:00:01  0:00:01 --:--:--   360

    liumiaocn:~ liumiao$ chmod +x operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin && sudo mkdir -p /usr/local/bin/ && sudo cp operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin /usr/local/bin/operator-sdk && rm operator-sdk-${RELEASE_VERSION}-x86_64-apple-darwin
    Password:
    liumiaocn:~ liumiao$

# 结果确认 #

liumiaocn:~ liumiao$ which operator-sdk
    /usr/local/bin/operator-sdk
    liumiaocn:~ liumiao$ operator-sdk version
    operator-sdk version: "v1.2.0", commit: "215fc50b2d4acc7d92b36828f42d7d1ae212015c", kubernetes version: "v1.18.8", go version: "go1.15.3", GOOS: "darwin", GOARCH: "amd64"
    liumiaocn:~ liumiao$

# 其他 #

BTW，Operator SDK开头的图的颜色的原因是因为这个。
