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 ``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

.. note::
|
|
|
|
You can also reference a flavor by ID.

|
+--------------------------------------+--------+--------+
|
|
|
|
This instance uses the ``cirros`` image.
|

|
|
+--------------------------------------+-------------+--------------------------------------+
|
|
|
|
This instance uses the ``selfservice`` self-service network. However, you
|
|
must reference this network using the ID instead of the name.
|
|
|
|
#. List available security groups:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack security group list
|

|
|
+--------------------------------------+---------+------------------------+
|
|
|
|
This instance uses the ``default`` security group.
|
|
|
|
#. Launch the instance:
|
|
|
|
Replace ``SELFSERVICE_NET_ID`` with the ID of the ``selfservice`` network.
|
|
|
|
.. code-block:: console

Access the instance using a 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 selfservice-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``.
|
|
|
|
