A completely closed source docker container

Question

I was wondering if it is possible to offer Docker images, but not allow any access to the internals of the built containers. Basically, the user of the container images can use the services they provide, but can't dig into any of the code within the containers.
Call it a way to obfuscate the source code, but also offer a service (the software) to someone on the basis of the container, instead of offering the software itself. Something like "Container as a Service", but with the main advantage that the developer can use these container(s) for local development too, but with no access to the underlying code within the containers.

My first thinking is, the controller of the Docker instances controls everything down to root access. So no, it isn't possible. But, I am new to Docker and am not aware of all of its possibilities.

Is this idea in any way possible?

Answer 1

An obfuscation-based only solution would not be enough, as "Encrypted and secure docker containers" details.

You would need full control of the host your containers are running in order to prevent any "poking". And that is not the case in your scenario, where a developer does have access to the host (ie his/her local development machine) where said container would run.
