[FEATURE] Import/Export Docker images/containers

When we back up our CyberPanel and migrate to a new setup, re-adding all the Docker images and containers can be a tedious process.

It would be incredibly helpful if there were an option to import/export these configurations.
Additionally, having a method to handle advanced environment variables (ENV) in bulk would save a lot of time, especially when dealing with multiple configurations. Currently, adding 12-20 ENV settings one by one is quite time-consuming.

For reference, here’s how Portainer allows users to manage ENV configurations in an advanced manner:

Here is how CyberPanel shows every ENV atm.

I’m in support of this, don’t swap out the current system but just add an advanced option.

I would also add that we should be able to manage exposed ports.
For instance, one of my Docker images for openlitespeed (running on centOS 7 to provide php 5 and 7 support) has 3 exposed ports, 80, 443, 7080.
When setting up, I may need to configure and use port 7080 but after that It’s not necessary to be used but in the current setup, I MUST port forward these ports.

After setup, I may just need port 443.

The current setup forces exposed ports without allowing modification which should not be which reduces the number of available ports and produces clutter.
