Launch an instance¶

To access your instance remotely¶

1. Add rules to the default security group:

   1. Permit ICMP (ping):

      $ nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
      +-------------+-----------+---------+-----------+--------------+
      | IP Protocol | From Port | To Port | IP Range  | Source Group |
      +-------------+-----------+---------+-----------+--------------+
      | icmp        | -1        | -1      | 0.0.0.0/0 |              |
      +-------------+-----------+---------+-----------+--------------+
      

   2. Permit secure shell (SSH) access:

      $ nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
      +-------------+-----------+---------+-----------+--------------+
      | IP Protocol | From Port | To Port | IP Range  | Source Group |
      +-------------+-----------+---------+-----------+--------------+
      | tcp         | 22        | 22      | 0.0.0.0/0 |              |
      +-------------+-----------+---------+-----------+--------------+
      

2. Create a floating IP address on the ext-net external network:

   $ neutron floatingip-create ext-net
   Created a new floatingip:

   | status              | DOWN                                 |
   | tenant_id           | 7cf50047f8df4824bc76c2fdf66d11ec     |
