kaniko executor dockerfile

kaniko is a tool to build container images from a Dockerfile, inside a container or Kubernetes cluster.. kaniko solves two problems with using the Docker-in-Docker build method: Docker-in-Docker requires privileged mode to function, which is a significant security concern. Once the extraction process is complete, you can shut down the init container, at which point the kaniko container takes over. By default, Unix socket is owned by the user root and other users can only access it using sudo command. ; Docker-in-Docker generally incurs a performance penalty and can be quite slow. referenced in COPY commands.
