    The title is kind of misleading, /etc/netplan/*.yaml is yaml

    1. 1

      What are the pros and cons of either method when using this vs. Ansible with networking modules?

      1. 3

        Well, Ansible’s networking modules aren’t actually at all about managing a general purpose server’s network configuration. They are all about logging into a managed switch/router (e.g. Cisco or Juniper hardware) and speaking the iOS shell configuration script.

        But I’m guessing that’s not what you mean, and actually are referencing using Ansible to deploy network configuration details to a bunch of servers. There is one fundamental difference in approach which should inform your choice: Netplan is local, Ansible is remote.

        Ansible requires a server to have an IP already so that it can reach it from a remote source (your laptop). Netplan is meant to run as part of the boot-up procedure, assigning the server it’s first IP address. Both could manage NetworkManager or systemd-networkd configuration, so then it’s a more personal choice. Between managing the configuration directly via Ansible and templated files or indirectly via a YAML configuration file for Netplan, which is more appropriate for your network?

        Personally, the way I’d see it, Netplan is much more useful in highly dynamic environments, like cloud providers. While Ansible fits a bit better in slightly more stable environments, such as on-premise deployments of small/medium companies.

      2. 1

        This project looks very similar in spirit to https://wiki.archlinux.org/index.php/Netctl, I’d be curious to play with this and see if it solves any issues netctl (which I’ve always used on my Arch systems) cannot (or as easily).

        1. 1

          On my Arch servers, I stick with systemd-networkd, how has netctl been for you?

          1. 1

            I’ve been using netctl since netcfg was deprecated a very, very long time ago - basically zero issues on my desktop or laptops (other than a really strange glance at a coffee shop once for using wifi-menu to connect…)

            netctl-auto is fantastic for laptop purposes too, generally speaking.

            I haven’t used systemd-networkd to give you any sense of comparison between the two.
