Describe the bug

Local images are prefixed with a tilde "\~" to avoid doing trying a pull of the image. The tilde is however not stripped when passing the image name to docker and thus the creation of the container fails. Somewhere in this code segment the image string has to be stripped if it starts with "\~": https://github.com/pterodactyl/wings/blob/3fda5485419404f87212eb06361f6834dc07e4b5/environment/docker/container.go#L159

To Reproduce

1. Create a new egg or edit an existing egg.
2. Set the image to a local image (aka prefix with "\~") and save
3. Create a server with this egg
4. Server will be stuck at "Installing" and Wings will show an error.

Expected behavior Server gets created using the local image.

If I am reading this right you are using a local container for the install process?

[grimsi]

No, the local container image is used to run the server

I have this issue as well when using local docker images
