feat: allow configuring docker container in local mode

 Additionally, Local Mode also requires Docker Compose V2. Follow the guidelines in https://docs.docker.com/compose/install/ to install.
 Make sure to have a Compose Version compatible with your Docker Engine installation. Check Docker Engine release notes https://docs.docker.com/engine/release-notes to find a compatible version.
