Dokumentation, wie im RZ bisher VMs angelegt werden. Stand: 01.11.2017

puppet
icinga

ibu (dns)
phenyl
plattenschwein
infra01 (dns2)

===== icinga_servicestatus =====
    .instance_id .service_object_id .output . current_state
    where current_state != 0
    service_object_id -> icinga_services.service_id

===== icinga_hosts =====
    .display_name .host_id

===== ro fs fix: =====
    ssh -X root@VMhost
    virt-manager
    vm shutdown & start

===== updates: =====
    icinga.shack...
    cssh root@host
    aptitude update
    aptitude safe-upgrade
    reboot ibu, phenyl, infra01

===== icinga mails disablen =====
    ssh icinga
    mv /etc/icinga2/conf.d/notifications.conf notifications.conf_

===== icinga check: =====
    ssh root@icinga.shack
    icinga2 daemon -C

===== neue VM: =====
        virt-manager wenn möglich vom VMhost verwenden (mit X forwarding)

        check load on ibu & phenyl -> decide
        virt-manager connect to VMhost
        virt-manager -> new
                PXE
                256 MB RAM & 1CPU
                managed or existing storage -> pool0 -> new volume (10GB)
                network: shared device name: br0
        pxe boot -> debian jessie amd64
        mirror ftp-stud.hs-esslingen.de
        proxy -> http://aptcache.shack
        root pass -> keepass
        user "shack" pass -> keepass root pass
        partition: guided lvm; all in one
        apt: standard utilities & ssh server
        aptitude install curl
        curl http://shack.shack/install/puppet | sh (| = Shift #)
        puppet agent --test
