Building images in CI/CD


I read introduction to this Packer guide and it say:

The majority of the Packer Builders can run in a container or VM, a common model used by most CI/CD services. However, the QEMU builder for KVM and Xen virtual machine images, VirtualBox builder for OVA or OVF virtual machines and VMWare builder for use with VMware products require running on a bare-metal machine.

I would like to be sure that’s still true because I plan to use GitLab and GitLab runners to build images and I want to be sure I need bare-metal machines.

Thanks for your feedback.

A bare-metal server would be a good platform for building OVA/OVF and similar images. You can definitely use “whatever you want” when building images for AWS or similar cloud providers.
