Why does Molecule make so many shell calls? Why does Molecule only support Ansible versions 2.2 and later? Why are playbooks used to provision instances? Have you thought about using Ansible’s python API instead of playbooks? Why are there multiple scenario directories and molecule.yml files? Are there similar tools to Molecule? Can I run Molecule processes in parallel? Can I specify random instance IDs in my molecule.yml? Can I test Ansible Collections with Molecule? Does Molecule support monorepos? How can I add development/testing-only dependencies?
