Launch an instance on the self-service network¶
Determine instance options¶
To launch an instance, you must at least specify the flavor, image name, network, security group, key, and instance name.
On the controller node, source the
democredentials to gain access to user-only CLI commands:$ . demo-openrc
A flavor specifies a virtual resource allocation profile which includes processor, memory, and storage.
List available flavors:
$ openstack flavor list +----+---------+-----+------+-----------+-------+-----------+ | ID | Name | RAM | Disk | Ephemeral | VCPUs | Is Public | +----+---------+-----+------+-----------+-------+-----------+ | 0 | m1.nano | 64 | 1 | 0 | 1 | True | +----+---------+-----+------+-----------+-------+-----------+
Note
You can also reference a flavor by ID.
List available images:
$ openstack image list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | 390eb5f7-8d49-41ec-95b7-68c0d5d54b34 | cirros | active | +--------------------------------------+--------+--------+
This instance uses the
cirrosimage.List available networks:
$ openstack network list +--------------------------------------+-------------+--------------------------------------+ | ID | Name | Subnets | +--------------------------------------+-------------+--------------------------------------+ | 4716ddfe-6e60-40e7-b2a8-42e57bf3c31c | selfservice | 2112d5eb-f9d6-45fd-906e-7cabd38b7c7c | | b5b6993c-ddf9-40e7-91d0-86806a42edb8 | provider | 310911f6-acf0-4a47-824e-3032916582ff | +--------------------------------------+-------------+--------------------------------------+
This instance uses the
selfserviceself-service network. However, you must reference this network using the ID instead of the name.List available security groups:
$ openstack security group list +--------------------------------------+---------+------------------------+ | ID | Name | Description | +--------------------------------------+---------+------------------------+ | dd2b614c-3dad-48ed-958b-b155a3b38515 | default | Default security group | +--------------------------------------+---------+------------------------+
This instance uses the
defaultsecurity group.Launch the instance:
Replace

Check the status of your instance:
$ openstack server list +--------------------------------------+----------------------+--------+------------------------+ | ID | Name | Status | Networks | +--------------------------------------+----------------------+--------+------------------------+ | 113c5892-e58e-4093-88c7-e33f502eaaa4 | selfservice-instance | ACTIVE | selfservice=172.16.1.3 | | 181c52ba-aebc-4c32-a97d-2e8e82e4eaaf | provider-instance | ACTIVE | provider=203.0.113.103 | +--------------------------------------+----------------------+--------+------------------------+
The status changes from
BUILDtoACTIVEwhen the build process successfully completes.
Access the instance using a virtual console¶
Obtain a Virtual Network Computing (VNC) session URL for your instance and access it from a web browser:
$ openstack console url show selfservice-instance +-------+---------------------------------------------------------------------------------+ | Field | Value | +-------+---------------------------------------------------------------------------------+ | type | novnc | | url | http://controller:6080/vnc_auto.html?token=5eeccb47-525c-4918-ac2a-3ad1e9f1f493 | +-------+---------------------------------------------------------------------------------+
Note
If your web browser runs on a host that cannot resolve the
controllerhost name, you can replacecontrollerwith the IP address of the management interface on your controller node.The CirrOS image includes conventional user name/password authentication and provides these credentials at the login prompt. After logging into CirrOS, we recommend that you verify network connectivity using
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
Verify access to the internet:
$ ping -c 4 openstack.org PING openstack.org (174.143.194.225) 56(84) bytes of data. 64 bytes from 174.143.194.225: icmp_req=1 ttl=53 time=17.4 ms 64 bytes from 174.143.194.225: icmp_req=2 ttl=53 time=17.5 ms 64 bytes from 174.143.194.225: icmp_req=3 ttl=53 time=17.7 ms 64 bytes from 174.143.194.225: icmp_req=4 ttl=53 time=17.5 ms --- openstack.org ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 17.431/17.575/17.734/0.143 ms
Access the instance remotely¶
Create a floating IP address on the provider virtual network:
$ openstack floating ip create provider +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | created_at | 2017-01-20T17:29:16Z | | description | | | fixed_ip_address | None | | floating_ip_address | 203.0.113.104 | | floating_network_id | b5b6993c-ddf9-40e7-91d0-86806a42edb8 | | headers | | | id | 88b4d06a-d794-4406-affd-6ffa2bcf1e2a | | port_id | None | | project_id | ed0b60bf607743088218b0a533d5943f | | revision_number | 1 | | router_id | None | | status | DOWN | | updated_at | 2017-01-20T17:29:16Z | +---------------------+--------------------------------------+
Associate the floating IP address with the instance:
$ openstack server add floating ip selfservice-instance 203.0.113.104
Note
This command provides no output.
Check the status of your floating IP address:
$ 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 Troubleshoot Compute documentation for Pike, the Troubleshoot Compute documentation for Queens, or the Troubleshoot Compute documentation for Rocky for more information or use one of the many other options to seek assistance. We want your first installation to work!
Return to Launch an instance.
