Container Linux!

  • ●Cloud Native! 

  • ●Minimal Footprint! 

  • ●IKEA vs. Artisanal 

  • ●Atomic updates!

But, what is “a Linux”?

  • ●Well, actually it’s GNU/Linux … 

     

  • ●What makes it “what people and tooling expect?” 

 

Is this a Linux?

  • ●syscalls, ioctls, fcntls? 

  • ●libc? 

  • ●Kernel CONFIG_’s? 

  • ●Config (/etc or CM tooling) 

  • ●Early boot provisioning? (ignition or cloud-init) ((secrets??)) 

  • ●Host services? (unit files and dbus?) 😩 

  • ●NVR of software 

 

A brief history

  • ●Read only? 

    • –Knoppix (2000) – a first of the “live” from CD Linuxes 

  • ●Minimal? 

    • –Damn Small Linux (2005) ~50Mb 

  • ●Isolation? 

    • –mountns (2002) 

  • ●“Userspace” 

    • –An ongoing swarm of iteration and improvements and sprawl 

 

A brief history

  • ●2008 LXC is launched 

  • ●2013 CoreOS releases the first “Container Linux” 

    • –based on the ChromiumOS created for Chromebooks 

    • –Gentoo is the upstream 

  • ●2013 dotCloud releases Docker 

  • ●2014 Kubernetes is launched 

  • ●Since then: Atomic; Flatcar; Talos; FedoraCoreOS (RHEL and CentOS too); bottlerocket; k3os; openSUSE Micro; LinuxKit; gardenlinux; and I’m sure others ... 

(other history talks at github.com/vbatts/talks)

 

Common Challenges

  • ●Do you know when something becomes artisanal? 

  • ●Package management 

    • –Trust 

    • –Proofs 

    • –Determinism (scriptlets; ordering; file system API’s) 

  • ●Who says a a reboot is needed? How? 

  • ●“Let’s innovate and think about how to migrate later!” 

  • ●“If folks should use my approach if they want things to work together!”  

     

 

Common Challenges

  • ●“is this change/rollout deterministic?” 

  • ●When you deploy “A Kubernetes”, that is not a definitive, standard thing. 

    • –Every extension, runtime, plugin, and even config field can have implicit and explicit variations needed. 

 

Don’t get me wrong

  • ●Packagers and Upstreams are critical 

  • ●The kernel and OS [interfaces] you use matter 

  • ●You end users and admins/ops/architects actively don’t care about your epiphany if you’ve made their life harder for no reason 

  • ●Everyone wants their precious to be the winner … 

 

Where are we now?

  • ●It depends... 

  • ●Compartmentalizing our frustration 🥺 

  • ●We’ve all suffered these pains, individually and collectively 

  • ●Renewed interest in defining and establishing the common OS interfaces 

  • ●What is your use-case? Let that drive you, not a marketing pitch 

 

💚 y’all

  • ●Find me online 

    • –Then we can talk like humans 

      • ●Let’s work together
