Derro is a project for running Vagrant inside a Docker container, providing a convenient and reproducible environment for Vagrant-based workflows. This setup is based on AlmaLinux 9 and includes all necessary tools for SSH, systemd, and Vagrant user provisioning.

• AlmaLinux 9 base image
• Systemd enabled for service management
• SSH server pre-configured and exposed on port 22
• Pre-created vagrant user with passwordless sudo
• Automatic setup of SSH keys for the vagrant user (using your GitHub public keys)
• Useful utilities pre-installed (git, wget, vim, python3, etc.)

docker build -t derro .

docker run --privileged -d \
  --name derro \
  -p 2222:22 \
  -v /sys/fs/cgroup:/sys/fs/cgroup:ro \
  derro

• The --privileged flag and cgroup mount are required for systemd to function properly inside the container.
• SSH will be available on port 2222 of your host.

ssh vagrant@localhost -p 2222
# Password: vagrant

By default, the container fetches your public keys from GitHub (https://github.com/iladin.keys). To use a different key, modify the relevant line in the Dockerfile.

• This image is intended for development and testing purposes.
• For full Vagrant functionality, you may need to install Vagrant and VirtualBox or another provider inside the container, or mount them from the host.

• Inspired by star3am/hashiqube
