k8s operator-sdk安装及使用

参考 知乎文章 Kubernetes Operator 快速入门教程,

​ Operator sdk github

​

1. 安装 参考 operator sdk 官方安装文档

   # set platform information
   export ARCH=$(case $(uname -m) in x86_64) echo -n amd64 ;; aarch64) echo -n arm64 ;; *) echo -n $(uname -m) ;; esac)
   export OS=$(uname | awk '{print tolower($0)}')
   
   # download 
   export OPERATOR_SDK_DL_URL=https://github.com/operator-framework/operator-sdk/releases/download/v1.12.0
   curl -LO ${OPERATOR_SDK_DL_URL}/operator-sdk_${OS}_${ARCH}
   
   # install
   chmod +x operator-sdk_${OS}_${ARCH} && sudo mv operator-sdk_${OS}_${ARCH} /usr/local/bin/operator-sdk
   
   

2. 使用

   operator-sdk init --plugins go/v3 --project-version 3

   报错go: can only use path@version syntax with ‘go get’ and ‘go install’ in module-aware mode

   。。。

   Error: failed to initialize project: unable to scaffold with “base.go.kubebuilder.io/v3”: exit status 1

   后者查不到，通过前一句猜测跟module有关，修改go环境变量后重试

   go env -w GO111MODULE="on"
   rm -rf *
   operator-sdk init --plugins go/v3 --project-version 3
   成功
