.. _launch-instance-public:
Launch an instance on the public 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 ``demo`` credentials to gain access to
user-only CLI commands:
.. code-block:: console
$ source demo-openrc.sh
#. A flavor specifies a virtual resource allocation profile which
includes processor, memory, and storage.
List available flavors:
.. code-block:: console
$ nova flavor-list
+-----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+-----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1 | m1.tiny | 512 | 1 | 0 | | 1 | 1.0 | True |
| 2 | m1.small | 2048 | 20 | 0 | | 1 | 1.0 | True |
| 3 | m1.medium | 4096 | 40 | 0 | | 2 | 1.0 | True |
| 4 | m1.large | 8192 | 80 | 0 | | 4 | 1.0 | True |
| 5 | m1.xlarge | 16384 | 160 | 0 | | 8 | 1.0 | True |
+-----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
This instance uses the ``m1.tiny`` flavor.
.. note::
You can also reference a flavor by ID.
#. List available images:
.. code-block:: console
$ nova image-list
+--------------------------------------+--------+--------+--------+
| ID | Name | Status | Server |
+--------------------------------------+--------+--------+--------+
| 38047887-61a7-41ea-9b49-27987d5e8bb9 | cirros | ACTIVE | |
+--------------------------------------+--------+--------+--------+
This instance uses the ``cirros`` image.
#. List available networks:
.. code-block:: console
$ neutron net-list
+--------------------------------------+---------+-----------------------------------------------------+
| id | name | subnets |
+--------------------------------------+---------+-----------------------------------------------------+
| 7e25a106-e978-4adb-a4ef-d46c6170254a | public | 0e62efcd-8cee-46c7-b163-d8df05c3c5ad 203.0.113.0/24 |
+--------------------------------------+---------+-----------------------------------------------------+
This instance uses the ``public`` provider network. However, you must
reference this network using the ID instead of the name.
.. note::
If you chose option 2, the output should also contain the private network.
#. List available security groups:
.. code-block:: console
$ nova secgroup-list
+--------------------------------------+---------+-------------+
| Id | Name | Description |
+--------------------------------------+---------+-------------+
| ad8d4ea5-3cad-4f7d-b164-ada67ec59473 | default | default |
+--------------------------------------+---------+-------------+
This instance uses the ``default`` security group.
Launch the instance
-------------------
#. Launch the instance:
Replace ``PUBLIC_NET_ID`` with the ID of the ``public`` provider network.
.. note::
If you chose option 1 and your environment contains only one network,
you can omit the ``--nic`` option because OpenStack automatically
chooses the only network available.
.. code-block:: console
$ nova boot --flavor m1.tiny --image cirros --nic net-id=PUBLIC_NET_ID \
--security-group default --key-name mykey public-instance

#. Check the status of your instance:
.. code-block:: console
$ nova list
+--------------------------------------+-----------------+--------+------------+-------------+----------------------+
| ID | Name | Status | Task State | Power State | Networks |
+--------------------------------------+-----------------+--------+------------+-------------+----------------------+
| 181c52ba-aebc-4c32-a97d-2e8e82e4eaaf | public-instance | ACTIVE | - | Running | public=203.0.113.103 |
+--------------------------------------+-----------------+--------+------------+-------------+----------------------+
The status changes from ``BUILD`` to ``ACTIVE`` when the build process
successfully completes.
Access the instance using the virtual console
---------------------------------------------
#. Obtain a :term:`Virtual Network Computing (VNC)`
session URL for your instance and access it from a web browser:
.. code-block:: console
$ nova get-vnc-console public-instance novnc
+-------+------------------------------------------------------------------------------------+
| Type | Url |
+-------+------------------------------------------------------------------------------------+
| novnc | http://controller:6080/vnc_auto.html?token=2f6dd985-f906-4bfc-b566-e87ce656375b |
+-------+------------------------------------------------------------------------------------+
.. note::
If your web browser runs on a host that cannot resolve the
``controller`` host name, you can replace ``controller`` with 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 public provider network gateway:
.. code-block:: console
$ ping -c 4 203.0.113.1

Access the instance remotely
----------------------------
#. Verify connectivity to the instance from the controller node or any host
on the public physical network:
.. code-block:: console
$ ping -c 4 203.0.113.103
PING 203.0.113.103 (203.0.113.103) 56(84) bytes of data.

#. Access your instance using SSH from the controller node or any
host on the public physical network:
.. code-block:: console
$ ssh cirros@203.0.113.103
The authenticity of host '203.0.113.102 (203.0.113.102)' 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 '203.0.113.102' (RSA) to the list of known hosts.
$
.. note::
If your host does not contain the public/private key pair created
in an earlier step, SSH prompts for the default password associated
with the ``cirros`` user, ``cubswin:)``.
If your instance does not launch or seem to work as you expect, see the
`OpenStack Operations Guide <http://docs.openstack.org/ops>`__ for more
information or use one of the :doc:`many other options <common/app_support>`
to seek assistance. We want your first installation to work!
Return to :ref:`Launch an instance <launch-instance-complete>`.
