====== Proxmox container 'wordpress.test' (entfernt) ======
===== Status =====
  * up and running as http://bytecluster0002.bytespeicher.org:8086
  * has problems with loopback device cause the server can't reach itself with the external URL

===== Container setup =====
  * image: debian10 with users
  * 1. Netzwerkinterface
    * eth0
    * 10.2.0.30/24 DG: 10.2.0.254; fd00:10:2:0::30/64 DGfd00:10:2:0::0
    * bridge: vmbr0

    * eth1, 
    * 10.3.0.30/24; fd00:10:3:0::30/64
    * bridge: vmbr1 
===== Ansible setup =====
  * verbindet man sich als unpriviligierter user und möchte ein Command als ein anderer, unpriviligierter user ausführen (z.B. www-data), benötigt man <code>allow_world_readable_tmpfiles = yes</code> in der ansible.cfg, damit dies nicht als Fehler zum Abbruch führt.
