Nginx Web Server

Deploys a single Instance with Nginx installed and configured, attached to a private network with a floating IP. Ready for static site hosting or reverse proxy use.

Architecture:

• 1 Instance (Nano — 2 vCPU, 2 GB RAM)

• 1 private network (10.200.0.0/24)

• 1 floating IP (public access)

• Security group allows HTTP, HTTPS, SSH

What is automated:

• Instance creation with selected flavor and image

• Private network and subnet

• Router attached to public network

• Floating IP assigned to Instance

• Security group with ports 22, 80, 443

• Nginx installed and started

Before you launch:

Update these parameters in the template or at launch time:

Parameter	Default	What to change
key_name	stack-test	Required. Replace with your SSH keypair name from Compute- Key Pairs.
image	Ubuntu 22.04 Updated	Change only if you need a different OS image.
flavor	Nano	Change only if you want a different Instance size.
volume_size	30	Increase if you need more disk space (in GB).
public_network	Public	Do not change unless your cloud has a different external network name.

key_name is the only parameter you must change before launching. Everything else works with defaults.

Nginx Template

Save as nginx-server.yaml and upload via Orchestration or Past Direct.
