K8S CI/CD Skaffold

安装 skaffold

curl -Lo skaffold https://storage.googleapis.com/skaffold/releases/latest/skaffold-linux-amd64
chmod +x skaffold
sudo mv skaffold /usr/local/bin

运行 skaffold（这里假定你已经有kubectl访问k8s的权限）

通过官方的入门实例，初步了解skaffold的运行机制

git clone https://github.com/GoogleContainerTools/skaffold
cd /root/skaffold/skaffold/examples/getting-started
由于网络访问的问题
修复一下 Dockerfile和skaffold.yaml为你自己docker可访问到的镜像仓库
我这里换成lorahz/skaffold-example
