docker image validation

Simply running a registry image from Docker Hub requires a lot of setting up, so lets go with the simplest way to do it: by cloning the repository from the update framework. The topic of Docker container security raises concerns ranging from Dockerfile securityrelating to the Docker base images and potential security misconfigurations,to the Docker container security at runtime regarding network ports, user privileges, Docker mounted filesystem access, and others. Replace path to the .github directory. Docker (Build, running & maintaining docker images) Bitcoin: Thorough understanding of bitcoin system and bitcoin rpc.
