VMs are coming any day now ~q3k, A.D. 2018

Our new internal highly-available Infrastructure/Platform-as-a-Service.

This runs in our datacenter (dcr01 on netbox). This is different from our ISP services or internal machines.

Currently hscloud is made up of two Kubernetes clusters named:

• k0.hswaw.net - it runs on the following machines: dcr01s22, dcr01s24, dcr03s16. It has 144 x86 cores and 368GB of RAM.
• k1.hswaw.net (new, wip, more details later). It runs on the following machines: dcr03s19n01, dcr03s19n02, dcr03s19n03. It has 144C/288T in x86 cores (EPYC 7451), and 256 GB of RAM.

We also have a half PB of storage on old SAS drives (most of it currently cold), accessible via Ceph (radosgw or Kubernets PersistentVolumes) across two Ceph cluster: waw3 (old, main, currently ~120TB), waw4 (new, wip, currently ~24TB).

Most services have been migrated from our old machines into Kubernetes. Exceptions are listed below.

You are also free to host your own personal stuff there within reason. See below for access.

Here's a list of services that currently live on Boston Packets, but we'd like to migrate to hscloud. Ask on #infra on how to contribute.

• https://owncloud.hackerspace.pl - work in progress.
• mailman (https://lists.hackerspace.pl) - the web service is already on k8s, but also proxied via boston. Mailman-core and the database (used by both web and core, postgres) are still on boston. (2025-01: on implr's todo list)
• ldap/kerberos - (hard) (2025-01: infowski has a WIP ldap replica)
• email services (exim, dovecot) - (hard)
• mun (irc bot)
• `~user` dir serving

List of services (listed as their kube namespace names) to (eventually) move to k1

This machine is a Supermicro A+ Server 2123BT-HTR, made up of 4 H11DST-B nodes. Each has 2x 24-core 48-thread AMD EPYC CPUs.

Nodes a,b,c (dcr03s19n{01,02,03}) make up the k1 cluster. The final node is Snowflake, a VM machine (hosting, among other things, Boston Packets).
