Hi all,

This is my first post here, so be gentle

I’ve created a Docker container to simplify running the Sonatype Nexus H2-to-PostgreSQL migrator, making it easier to test and use.

You can find the project here:

- [GitHub - ferry/nexus-h2-to-psql-migrator: A containerized tool for migrating a Sonatype Nexus 3 H2 database to PostgreSQL](https://github.com/ferry/nexus-h2-to-psql-migrator)

It includes:

- A Dockerfile
- Support for passing database parameters via environment variables
- The necessary jars for the Nexus migrator and H2 database tooling

Feedback and contributions are welcome!
