• 104: Best practices

  • Going into IaC

    • Use git to track your tree

    • D.R.Y.

      • Things are quite easily moving

  • Code structure

    • Profile and Class

      • Role and profiles key lookup

    • Hierarchies

      • Foreman

    • Use environnements, site, locatation …

    • Common keys vs dedicated keys

      • The profile key, default placeholder

    • The resource modele

      • It’s like a puppet resource, a catalog of items to apply

      • It’s possible to use this model with ansible, and it change radically the way Ansible can be used then. See integration.

  • Debugging

    • Use the explain mode

      • And trace mode

    • Use GNU tools

      • tree

      • grep -Rw .

      • git status -sb

  • With ansible.

    • Use a strict naming scheme, apply your Ansible usual name schema into Kheops

    • You can put some jinja variable into Kheops, Ansible will be able to replace and understand them during the runtime

    • Dynamic inventories and ENC

    • Apply products

    • Apply roles/profiles pattern

    • Use resource based roles => See my collection, it just works
