Can data loss situations occur when stopping a container?

Yes, stopping a container can lead to data loss situations, especially if:

• Data is in memory and has not been written to disk (for example, in cache or buffers).
• Temporary files or databases inside the container are used without an external volume.
• Processes do not terminate correctly and do not have time to save their state.

To avoid data loss, it is recommended to:

• Use persistent volumes to store data outside the container.
• Ensure proper process termination (for example, handling SIGTERM signals).
• Regularly save state and data to disk.

Example: if a database runs inside a container without an external volume, all data can be lost when the container is stopped.
