Quick start

1. Deploy from the Azure Marketplace (Get It Now → Create), choosing your SSH key at the Administration step.
2. Allow inbound SSH (22) for yourself plus the application port(s): 5601 (Dashboards) and, for API clients, 9200 — restrict to your own IP where possible. The in-image firewall already allows them; only the Network Security Group (NSG) keeps them closed.
3. Open http://<VM-IP>:5601/ and sign in as admin (see First login below).
4. Create an index pattern and start ingesting via the REST API on https://<VM-IP>:9200 (Beats/Logstash/Data Prepper compatible).

Get your admin password (one time)

ssh <your-username>@<VM-IP>
sudo cat /var/lib/opensearch/admin-password

Sign in as admin. The REST API on 9200 is HTTPS with self-signed demo certificates (use -k / your CA); replace them and rotate the password before exposing the node.
