kubeless-原生的serverless初探

参考官网：https://kubeless.io/docs/quick-start/

安装kubeless（WITH RBAC ENABLED）

export RELEASE=$(curl -s https://api.github.com/repos/kubeless/kubeless/releases/latest | grep tag_name | cut -d '"' -f 4)
kubectl create ns kubeless
kubectl create -f https://github.com/kubeless/kubeless/releases/download/$RELEASE/kubeless-$RELEASE.yaml

安装UI (https://github.com/kubeless/kubeless-ui)

kubectl create -f https://raw.githubusercontent.com/kubeless/kubeless-ui/master/k8s.yaml

k8s服务器中安装CLI工具

export OS=$(uname -s| tr '[:upper:]' '[:lower:]')
curl -OL https://github.com/kubeless/kubeless/releases/download/$RELEASE/kubeless_$OS-amd64.zip && \
  unzip kubeless_$OS-amd64.zip && \
  sudo mv bundles/kubeless_$OS-amd64/kubeless /usr/local/bin/

事例参考 https://github.com/kubeless/kubeless/tree/master/examples
部署function

kubeless function deploy hello --runtime python2.7 \
                                --from-file test.py \
                                --handler test.hello

调用。kubeless

kubeless function call hello --data 'Hello world!'

也可以通过UI来调用

默认是导出为k8s的service，ClusterIP类型。所以可以在kubernetes内部中调用

$ curl http://hello:8080 -X POST -d 'TSET!!'
TSET!!

也可以导出ingress。参考官方网站https://kubeless.io/docs/http-triggers/。支持情况各不相同，如不行，手动创建一个igress文件也可
自定义运行环境参考 https://my.oschina.net/u/160697/blog/4772731
