This is really dependent on whether or not you want to interact with mounted volumes. In a production setting, containers are ephemeral and should essentially never be touched. Data is abstracted into stores like a database or object storage. If you’re interacting with mounted volumes, it’s usually through a different layer of abstraction like Kibana reading Elastic indices. In a self-hosted setting, you might be sidestepping dependency hell on a local system by containerizing. Data is often tightly coupled to the local filesystem. It is much easier to match the container user to the desired local user to avoid constant
sudocalls.I had to check the community before responding. Since we’re talking self-hosted, your advice is largely overkill.
… basically anything. Yes. You will always find yourself in problems where the best practice isn’t the best solution for.
In your described use case an option would be having the application inside the container running with
10000:10001but writing the data into another directory that is configured to use1000:1001(or whatever the user is you want to access the data with from your host) and just mount the volume there. This takes a bit more configuration effort than just running the application with1000:1001… but still :)
