OpenNebula Chart

Containers to do

  • oned: main api
    • also needs ssh files
  • scheduler
  • mysql for data
  • sunstone
  • novnc
  • nginx on 443

Storage:

  • mysql pvc (prod: 65G!)

DB upgrade to be run when upgrading opennebula:

sh-4.4# onedb upgrade -S 127.0.0.1 -P 3306 -u root -d opennebula

Tests / Migration

Containers done

Scheduler

Needs /etc/one/sched.conf.

[root@opennebula-opennebula-6cbb864798-txfhf one]# /usr/bin/mm_sched Could not open file /root/.one/one_auth

[root@opennebula-opennebula-6cbb864798-txfhf one]# mkdir /root/.one
[root@opennebula-opennebula-6cbb864798-txfhf one]# vi /root/.one/one_auth
[root@opennebula-opennebula-6cbb864798-txfhf one]# /usr/bin/mm_sched

DB cleanup

  • via cronjob
  • maybe 1/month
ALTER TABLE vm_pool DROP INDEX ftidx;
ALTER TABLE vm_pool ADD FULLTEXT INDEX ftidx (search_token);

Oned

  • Needs SSH keys
  • Define secret and provide out-of-band?

certbot for nginx

nginx for sunstone

Sunstone

templates: sunstone-server - needs ssl certificates access

files:

  • /var/lib/one/.one/one_auth
  • /var/lib/one/.one/sunstone_auth

Maybe via latent / hanging secret?

cmd:

mkdir -p /run/lock/one
mkdir -p /run/one
ruby /usr/lib/one/sunstone/sunstone-server.rb

File upload

From the website:

If you want to upload files to OpenNebula, you will have to share the uploads directory (/var/tmp by default) between Sunstone and oned. Some servers do not take into account the TMPDIR environment variable, in which case this directory must be defined in the configuration file (:tmpdir). It may also be necessary to set it in Passenger (client_body_temp_path).

We can probably do without it using the hostpath

Fireedge

  • Basically a guacamole viewer, which we already have
