Launch an instance on the provider 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
|
|
|
|
$ . demo-openrc
|
|
|
|
#. A flavor specifies a virtual resource allocation profile which
|
|
includes processor, memory, and storage.
|
|
|
|
List available flavors:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack flavor list
|
|
|
|
+----+---------+-----+------+-----------+-------+-----------+

|
|
| 0 | m1.nano | 64 | 1 | 0 | 1 | True |
|
|
+----+---------+-----+------+-----------+-------+-----------+
|
|
|
|
.. note::
|
|
|
|
You can also reference a flavor by ID.
|
|
|
|
#. List available images:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack image list
|

|
|
+--------------------------------------+--------+--------+
|
|
|
|
This instance uses the ``cirros`` image.
|
|
|
|
#. List available networks:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack network list

|
|
+--------------------------------------+--------------+--------------------------------------+
|
|
|
|
This instance uses the ``provider`` 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
|
|
``selfservice`` self-service network.
|
|
|
|
#. List available security groups:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack security group list
|
|
|
|
+--------------------------------------+---------+------------------------+----------------------------------+
|
|

|
|
+--------------------------------------+---------+------------------------+----------------------------------+
|
|
|
|
This instance uses the ``default`` security group.
|
|
|
|
Launch the instance
|
|
-------------------
|
|
|
|
#. Launch the instance:
|
|
|
|
Replace ``PROVIDER_NET_ID`` with the ID of the ``provider`` 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
|
|
|
|
$ openstack server create --flavor m1.nano --image cirros \
|
|
--nic net-id=PROVIDER_NET_ID --security-group default \
|

#. Check the status of your instance:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack server list
|

|
|
+--------------------------------------+-------------------+--------+------------------------+------------+
|
|
|
|
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
|
|
|
|
$ openstack console url show provider-instance
|
|

|
|
+-------+---------------------------------------------------------------------------------+
|
|
|
|
.. 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``.
|
|
|
|
