Launch an instance on the self-service network¶
Zjištění možností instance¶
Pro spuštění instance je třeba minimálně zadat její konfiguraci, název jejího obrazu, síť, bezpečnostní skupinu, klíč a její název.
V uzlu kontroléru použijte příkaz source pro přihlašovací údaje pro
demopro získání přístupu k příkazům příkazového řádku pro uživatele:$ . demo-openrcKonfigurace určuje profil přidělení virtuálních zdrojů zahrnující procesory, paměť a úložný prostor.
Vypište dostupné konfigurace:
$ openstack flavor list +----+---------+-----+------+-----------+-------+-----------+ | ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public | +----+---------+-----+------+-----------+-------+-----------+ | 0 | m1.nano | 64 | 1 | 0 | 1 | True | +----+---------+-----+------+-----------+-------+-----------+
Poznámka
Na konfiguraci můžete také odkazovat pomocí jejího ID.
Vypište dostupné obrazy:

This instance uses the
selfserviceself-service network. However, you must reference this network using the ID instead of the name.Vypište dostupné bezpečnostní skupiny:

Získání přístupu k instanci pomocí virtuální konzole¶
Získejte URL sezení Virtual Network Computing (VNC) pro vaší instanci a použijte ji ve vašem prohlížeči:
$ openstack console url show selfservice-instance +-------+---------------------------------------------------------------------------------+ | Field | Value | +-------+---------------------------------------------------------------------------------+ | type | novnc | | url | http://controller:6080/vnc_auto.html?token=5eeccb47-525c-4918-ac2a-3ad1e9f1f493 | +-------+---------------------------------------------------------------------------------+
Poznámka
Pokud váš internetová prohlížeč běží na hostiteli, který nemůže přeložit název hostitele
controller, můžete jej nahradit Ip adresou rozhraní pro správu na vašem uzlu kontroléru.Obraz CirrOS obsahuje standardní ověření pomocí uživatelského jména/hesla a tyto údaje jsou poskytnutí při přihlašování. Po přihlášení Vám doporučujeme ověřit připojení k síti pomocí příkazu
ping.Verify access to the self-service network gateway:
$ ping -c 4 172.16.1.1 PING 172.16.1.1 (172.16.1.1) 56(84) bytes of data. 64 bytes from 172.16.1.1: icmp_req=1 ttl=64 time=0.357 ms 64 bytes from 172.16.1.1: icmp_req=2 ttl=64 time=0.473 ms 64 bytes from 172.16.1.1: icmp_req=3 ttl=64 time=0.504 ms 64 bytes from 172.16.1.1: icmp_req=4 ttl=64 time=0.470 ms --- 172.16.1.1 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2998ms rtt min/avg/max/mdev = 0.357/0.451/0.504/0.055 ms
Ověřte přístup k internetu:

Přidružte plovoucí IP adresu k instanci:
$ openstack server add floating ip selfservice-instance 203.0.113.104
Poznámka
Tento příkaz nemá žádný výstup.
Zkontrolujte stav svých plovoucích IP adres:
$ openstack server list +--------------------------------------+----------------------+--------+---------------------------------------+ | ID | Name | Status | Networks | +--------------------------------------+----------------------+--------+---------------------------------------+ | 113c5892-e58e-4093-88c7-e33f502eaaa4 | selfservice-instance | ACTIVE | selfservice=172.16.1.3, 203.0.113.104 | | 181c52ba-aebc-4c32-a97d-2e8e82e4eaaf | provider-instance | ACTIVE | provider=203.0.113.103 | +--------------------------------------+----------------------+--------+---------------------------------------+
Verify connectivity to the instance via floating IP address from the controller node or any host on the provider physical network:
$ ping -c 4 203.0.113.104 PING 203.0.113.104 (203.0.113.104) 56(84) bytes of data. 64 bytes from 203.0.113.104: icmp_req=1 ttl=63 time=3.18 ms 64 bytes from 203.0.113.104: icmp_req=2 ttl=63 time=0.981 ms 64 bytes from 203.0.113.104: icmp_req=3 ttl=63 time=1.06 ms 64 bytes from 203.0.113.104: icmp_req=4 ttl=63 time=0.929 ms --- 203.0.113.104 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3002ms rtt min/avg/max/mdev = 0.929/1.539/3.183/0.951 ms
Access your instance using SSH from the controller node or any host on the provider physical network:
$ ssh cirros@203.0.113.104 The authenticity of host '203.0.113.104 (203.0.113.104)' can't be established. RSA key fingerprint is ed:05:e9:e7:52:a0:ff:83:68:94:c7:d1:f2:f8:e2:e9. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '203.0.113.104' (RSA) to the list of known hosts.
If your instance does not launch or seem to work as you expect, see the Instance Boot Failures section in OpenStack Operations Guide for more information or use one of the many other options to seek assistance. We want your first installation to work!
