====== X2Go: The Spread 2021.5 ======
{{:events:spread_something_special.png?nolink&400|spread something special}}

===== Quick Facts =====
**This is the replacement event for X2Go: The Gathering 2021, which had to be cancelled due to illness of several core members.**

**Location:** 100% online

**Date:** 2022-11-28 to 2022-12-02

**Event type:** 5 days, but evening-only - starting around 18:00 CET, with a maximum of one or two short talks/presentations (around 20-30 minutes each), followed by discussions, jointly working on open tasks, bugsquashing, "open coding"

**Sponsorship:** As this is a purely virtual event, we are not in need for event sponsors. However, X2Go could still use some more donations to cover hosting costs, so if you have a few $$$/€€€/£££ to spare, you can find our donation forms here:
  *  [[https://www.betterplace.org/en/projects/111056?wirwunder=235|English-language donation form]]
  *  [[https://www.wirwunder.de/projects/111056?wirwunder=235|German-language donation form]]


**What's that name all about?**
As our idea of running an annual [[events:2012|hacktrain]] had to be cancelled permanently back in 2014, we chose the name "X2Go: The Gathering" for the new type of annual event we hosted since then. This year, the //spread// of the of the Corona virus around the globe and across Germany makes it impossible for us to gather safely, which is why we are meeting virtually instead, while being physically //spread// out across the real world.
Also, for everyone actively taking part in the event, please be prepared to show your favorite breakfast //spread// while on camera. ;)

Note: A separate, virtual event called X2Go: The Spread 2022 will take place from 2022-12-12 to 2022-12-16 (i.e. roughly two weeks from 2021.5). Details for that event can be found [[events:x2go-spread-2022|here]].

==== X2Go-TCE-Live ====
  * buster and bullseye feature branches should be copied to code.x2go.org (ToDo Juri: Done)
  * We should agree on a new branch structure for it, but this doesn't really make sense before we're on Gitlab

==== Server infrastructure ====
  * needs to be discussed with h1, m#1, ionic and Juri present
  * scheduled for Tue, 2022-11-29, 19:15/19:30
  * We should start with an overview: 
    * Which service is running on which instance (think DNS name)
      * DNS 
        * currently - Hetzner (Login Data: h1, alex)
        * todo: multi-user or orca, LXC or similar
        * Juri will set up an account for orca at https://desec.io/
        * Needs discussion with alex b/c some services might still be in use by him
      * Wiki - on bare metal "japsand" owned by h1
      * jenkins - on bare metal "japsand" owned by h1
      * package build services - on bare metal "japsand" owned by h1
      * Windows virtual machine (KVM) - on bare metal "japsand" owned by h1
        * jenkins agent
        * manually operated on demand as well
      * git - KVM "ymir" hosted by Mike
      * code - Alias for git
      * packages - KVM "ymir" hosted by Mike

      * bugs - KVM "ymir" hosted by Mike
      * lists - KVM "ymir" hosted by Mike
      * launchpad - external, package build services for Ubuntu
      * gitlab - LXC on bare metal "mellum" owned by h1
      * nothing else on mellum at the moment
      * macOS package builds - 2 servers at flow.swiss, currently paid via Stefan/orca
      * POWER package builds - 2 servers at OSUOSL, free
      * POWER Demo boxes - 2 servers at OSUOSL, free


    * Which instance is running on which physical host
    * Which physical host belongs to whom (think ADMIN-C/person paying the bills)
      * ymir (KVM) belonging to Mike
      * japsand bare metal belonging to h1
      * mellum bare metal belonging to h1
    * Which additional DNS aliases are defined for one and the same box (think www vs. wiki, code.x2go.org vs.git.x2go.org)
    * What are the current issues
      * hosting costs
      * old hardware
      * lack of redundancy
      * access to some boxes/services limited to one person (think DNS) 
    * ToDo Stefan: Send Follow-Up eMail to h1, Mike, ionic
==== Gitlab migration ====
  * mellum (host for gitlab repo) seems to be down? Investigating the cause. (Juri, ionic) -> Opened ticket with Hetzner
  * mellum hardware was replaced by hetzner
  * mellum in vkvm mode works
  * minimized network konfiguration and reboot -> doesn't work right now.

==== OSUOSL ====
  * clemens still has an OpenStack account, but hasn't really been active lately
    * Juri would love to have access
    * Maybe we could turn clemens' account into one for Juri?
    * Stefan has contacted OSUOSL to create an account for Juri, either by renaming clemens' or by cloning it and disabling the original one afterwards
  * Updates/Upgrades: Done!
==== Mac M1 hosting ====
  * [[https://www.scaleway.com/en/hello-m1/|scaleway.com]] 8c16g256SSD macOS 12 Monterey. €0.10/hour
  * [[https://www.hetzner.com/de/dedicated-rootserver/brands/matrix-apple?ref=wwLgxUGidWtX|hetzner.com]] 8c16g256SSD €64,02 per month + €58,31 setup
  * [[https://checkout.macincloud.com/select/dedicated|macincloud.com]] 4c4g50SSD macOS Ventura 13.x (Supports the latest Xcode 14.x) for €589.88 EUR + 8GB RAM - €94.28 EUR or 16GB - €188.68 EUR per year


==== Regular Hosting Alternatives ====
  * https://oneprovider.com/configure/dediconf/4876 (via Juri)

==== X2Go-TCE-Live-Builds ====
  * iso-hybrid images for amd64 and i686: both buster and bullseye TCE and MMD build without errors
  * hdd images for arm64: both buster and bullseye TCE and MMD build without errors
  * Tests if images are bootable:
    * amd64 TCE OK
    * amd64 MMD OK
    * arm64 seems to be broken, needs further investigation
    * more tests later on

==== X2Go-Broker-Demo-Environment ====
  * Idea: Instead of KVM + NFS, use LXC + bind-mount homedirs between fileserver and x2goservers from host
