Providing Additional Files to Docker

SecretVM lets you attach an optional .tar archive containing extra files your workload needs at runtime.

When provided, the archive is automatically unpacked into the ./usr/ directory inside your SecretVM environment.

These files become available to Docker Compose and can be mounted into your containers just like any local path.

How it works

1. Upload a .tar archive.

2. SecretVM extracts it into: ./usr/

3. You can then reference any file inside that directory via standard Docker volume mounts.

Example:

volumes:

- ./usr/myfile:/app/myfile

Typical Use Cases

• Supplying config files or secrets that aren’t stored in the image

• Bundling auxiliary scripts or models

• Including static assets needed at runtime

This feature is optional and only needed for advanced workloads requiring external file bundles.
