Restart container is not functional

[emutanen]

Restarting containers

Setting up container is done when creating a new instance.

Steps to reproduce

1. Create a new repository type instance
2. Stop the instance by clicking cloud icon in the management view
3. Restart instance by clicking the cloud icon after the container has stopped
4. Open instance log to see failure

Possible cause for the issue

1. Usually the container is created with a src/ folder in them
2. Restarting a container tries to copy the repositroy again in the container in 3. Since the destination folder exists, restarting fails at copy phase
