No native Docker support

[denismakogon]

As it's said in README: 1000% satisfaction guaranteed when it's not. This type of installation does not work on Docker, Rkt, Kubernetes.
cfy_manager install script attempts to use sudo everytime it thinks of limited rights of the user that started this script.

On Fedora (on Docker):

cfy_manager install

This particular error says that there's no sudo, but as root i don't need sudo. Moreover, Docker images don't have sudo, they run by default from the root.

Well, the usage of sudo was left in the code in order to support VMs as well as containers. The simple solution to your problem is to install sudo (yum install sudo).
You can see that docker is clearly supported by the fact that we actually install the manager on containers in our CI. Here's the Dockerfile that we use.
You would need a similar file in order for the installation to work.
You can see here the complete sequence we use to install on a container.

Would be nice to have an in-tree Dockerfile that pulls does all stuff. Moreover, would be nice to have the docker-compose file that deploys distributed manager (not talking about HA mode that premium Cloudify supports).

[mcouthon]

We didn't have a need for such a Dockerfile until now, but maybe in the future we'll do something like this.
