Loose Notes

Have something you want to document, but not sure where to put it or how to format it ? Please go right ahead and dump it into the pre-formatted text block below!!

resize qemu image:
  # first, shut down the capsul, then:
  $ cd /tank/vm
  $ qemu-img resize cvm-lqj2x9nxic.qcow2 +50G
  $ virsh start cvm-lqj2x9nxic.qcow2

you may have to resize the partition by hand internally, depending on the distro.

For alpine:
mothership:~# apk add e2fsprogs e2fsprogs-extra
...
mothership:~# resize2fs /dev/vda
resize2fs 1.46.6 (1-Feb-2023)
Filesystem at /dev/vda is mounted on /; on-line resizing required
old_desc_blocks = 2, new_desc_blocks = 7
The filesystem on /dev/vda is now 25690112 (4k) blocks long.

mothership:~# df -h

Physical Hosts

• baikal

  • 69.61.110.118

  • cyberia's first rack server, installed in CyberWurx datacenter in Atlanta Georgia

  • j3s and forest are the only authorized support contacts on the CyberWurx portal right now

• beet

  • beet was recently rebuilt with a new motherboard and CPU. it has 4x 2GB HDDs

  • it's currently located at layer zero - ssh layerze.ro

Cloud Service Accounts

• namecheap.com

  • we use j3s's to manage DNS entries for:

    • cyberia.club

    • nullhex.com

    • capsul.org

  • all DNS updates are automated via git.cyberia.club/cyberia/dns

  • conventions:

    • A records are named after hostnames & point to VMs / physical hosts

    • CNAMEs are named after the service & point to the A record of the host the service runs on

• CyberWurx portal

  • Allows us to add reverse DNS entries for Capsuls

  • View metrics, get datacenter information, support tickets, etc

  • Right now j3s/forest are the only one who can log in / be authorized for support. Can add others though!

• Capsul.org

  • Cyberia has an internal capsul account that we use. If you want access to this account, talk to j3s, vvesley, or forest.

• njal.la

  • For redundancy and random domains, such as:

    • cyberia.top

    • cyberia.tube

    • cyberia.social

  • conventions: None. DNS updates are currently not automated. To update dns or to add / manage domains log into njal.la with treasurer@cyberia.club or use the api.

Capsul

Most of cyberia's services run on Capsul, our Virtual Machine Management tool & service.

Automation (Ansible)

The [Ops Handbook](git.cyberia.club/services/ops-handbook/) is still on the old git server, it is the main repo with the ansible inventory & playbooks.

Ansible bastion host/automation is on leckie.cyberia.club

Service Inventory

Metrics Inventory

We use Prometheus and Grafana to capture, store, and display metrics related to our services.

There are four main dashboards in grafana:

• Node Exporter

  • The prometheus node exporter runs on all of our servers and is managed by ansible.

• Postgres Overview

  • These metrics are reported by a postgres exporter which was installed manually on matrix.cyberia.club and legion.cyberia.club

• Cyberia Synapse

  • These metrics are reported by synapse itself. If they are not working, it may be an issue with the reverse proxy in front of synapse.

• Capsul Stats

  • these metrics are reported by git.cyberia.club/cyberia/libvirt_exporter (running on baikal). They are used to generate the graphs in the capsul.org web interface

LetsEncrypt Certificate Inventory

For information on certificates which are managed by uacme automatically, see
git.cyberia.club/services/ops-handbook/tree/ansible/hosts
and the tls_certs variable in git.cyberia.club/services/ops-handbook/tree/ansible/group_vars

Certificates which are exceptions to the rule:

btcpay.cyberia.club
 - btcpay.cyberia.club certificate is automatically managed by the caddy server running on elliot

baikal.cyberia.club
elliot.cyberia.club
The following are managed by a script called acme.sh located at `/root/.acme.sh/`
 - capsul.org
 - www.capsul.org
 - nullhex.com
 - cyberia.club
 - git.cyberia.club

matrix.cyberia.club
The following are managed by a script called acme.sh located at `/root/.acme.sh/`
  - matrix.cyberia.club
  - riot.cyberia.club

beet.cyberia.club
The following are managed by Caddy on the router which sits in front of beet. Ask j3s or fack about this.
  - cafe.cyberia.club

The following are managed by acme.sh
  - mumble.cyberia.club

systemctl stop mumble-server nginx
acme.sh renew mumble.cyberia.club
cp /root/.acme.sh/mumble.cyberia.club/mumble.cyberia.club.cer /etc/murmur/cert.pem
cp /root/.acme.sh/mumble.cyberia.club/mumble.cyberia.club.key /etc/murmur/key.pem
systemctl start mumble-server nginx

paimon.cyberia.club
The following are managed by something that sanine set up. Ask sanine about this.
  - git.cyberia.club

nyanjaro.cyberia.club
The following are updated by a cron job that nyaaori made. it calls /etc/letsencrypt/renew.sh
  - bridges.cyberia.club

How to use acme.sh:

systemctl stop nginx ; acme.sh --renew --domain git.cyberia.club; systemctl start nginx ;

If you get an error like

Please specify at least one validation method: '--webroot', '--standalone', '--apache', '--nginx' or '--dns' etc.

Then you must edit the config file, for example

nano root@elliot:~/.acme.sh# nano cyberia.club/cyberia.club.conf

and change Le_Webroot='' to Le_Webroot='no' inside the <domain-name>/<domain-name.conf> file. [see: github issue](github.com/acmesh-official/acme.sh/issues/1172)

certificate expiry alerts

The certificate expiry alerts are defined here: git.cyberia.club/services/ops-handbook/tree/rules/alerts.yml#n112

The probe_ssl_earliest_cert_expiry metric is written by the blackbox exporter, configured here: git.cyberia.club/services/ops-handbook/tree/ansible/roles/prometheus/templates/prometheus.yml.j2#n82
