Web server using OpenStack

A minimal example that provisions a Fedora instance and its security group rules on OpenStack.

Prerequisites

1. Install Pulumi
2. Configure Pulumi for OpenStack
3. Install Python

Deploying the example

1. Create a new stack:

   pulumi stack init

2. Install dependencies:

   python3 -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt

3. Modify __main__.py to include your keypair and image.

4. Run pulumi up to preview and deploy changes:

   pulumi up

   Previewing update (dev):
       Type                                  Name           Plan
       pulumi:pulumi:Stack                   pulum-dev
   +   ├─ openstack:images:Image             fedora         create
   +   ├─ openstack:compute:Keypair          default        create
   +   ├─ openstack:networking:SecGroupRule  secgroupRule1  create
   +   ├─ openstack:networking:SecGroupRule  secgroupRule2  create
   +   ├─ openstack:networking:SecGroupRule  secgroupRule3  create
   +   └─ openstack:compute:Instance         test_fedora    create
   
   Outputs:
   ~ instance_ip: "192.168.0.243" => output<string>
   
   Resources:
       + 6 to create
       1 unchanged
   
   Duration: 38s
   

5. View the host name and IP address of the instance via stack output:

   pulumi stack output

   Current stack outputs (1):
       OUTPUT       VALUE
       instance_ip  192.168.0.243
   

6. Verify that the OpenStack instance exists, by either using the Horizon dashboard or running openstack server list:

   openstack server list

   +--------------------------------------+-------------+--------+-------------------------------------+--------------------------+----------+
   | ID                                   | Name        | Status | Networks                            | Image                    | Flavor   |
   +--------------------------------------+-------------+--------+-------------------------------------+--------------------------+----------+
   | 8bdf8a6d-ac53-4448-ae09-e2a08ad554a0 | test_fedora | ACTIVE | public=192.168.0.243, 2001:db8::36b | fedora                   | m1.small |
   +--------------------------------------+-------------+--------+-------------------------------------+--------------------------+----------+
   

Cleaning up

Once you're finished experimenting, destroy your stack and remove it to avoid incurring any additional cost:

pulumi destroy
pulumi stack rm
