Docker Remote API & Binds

will help you Bad news I tried to set texture width and height with power of 2 value (1024x1024) and It worked:

hop of those help? UPDATE:
You configuration seems ok to me, but I think that ports 49160-49162 should be bind to IPv4 interface not IPv6. I googled this and it seems that you encountered an open bug in docker:

I hope this helps you . The docker CLI is the client half of a client/server architecture (dockerd or in past versions docker daemon is the other half). When you use docker-machine, it is updating environment variables including $DOCKER_HOST which tells docker to connect to another host. The default is to connect to the socket on the local host. The value of $DOCKER_HOST overrides that, and the CLI flag docker -H ... overrides both of those.
The most common reason to have a container spin up on an unexpected host is when you forget to set/unset $DOCKER_HOST.

it helps some times No; Docker Compose itself is an application that uses the API. You’d need to directly run docker-compose up or something similar as a shell command if you wanted to directly use it.
(You might be able to hack into its internals if you have a Python program, but not from Java.)

This might help you
But how do I change the permissions of a mounted file? Can it be done via Dockerfile, or must it already be present before that starts?
