In GNS3, by default, nothing will persist after reloading your project unless your Docker Container is configured to do so. Your Docker Container may not be configured to have persistent data. This behavior is described in the official GNS3 documentation.

PERSISTENCE

By default nothing is persisted on disk. The container needs to be designed for that.

If in the Dockerfile the container mount volumes. GNS3 will create in the project folders a folder for each Docker volume and will write file inside.

This mean if you use a container outside GNS3 the data will not be available. But also this mean all the data of the GNS3 project is in the same location.

Depending on your use-case, a simple work-around could be to use VPCs or the pre-built Ubuntu Docker appliance as hosts instead.
