This example uses a public Nginx image and a published port. It needs a working installation, an Admin to create the group, and an Operator or Admin to deploy.
Prepare access
Use a working installation. An Admin creates the group; an Operator or Admin can deploy the application. Ensure the server can pull the public Nginx image from Docker Hub. TCP port 8080 must be available and reachable from your computer.
For SSH access, run this on your computer and keep the session open:
ssh -L 9000:127.0.0.1:9000 -L 8080:127.0.0.1:8080 your-user@server.example.comSteps
Create a group
Create a group named
demo.Configure the application
Create an application named
hello-webin that group, usingnginx:stable-alpine. Keep the image’s default startup command and one fixed replica.Publish a port
Publish container port 80 as host port 8080, using TCP.
Deploy the application
Save and wait for the replica to run.
No domain, custom command, configuration file, or persistent volume is needed. The official Nginx image already starts its web server in the foreground.
Verify a request
From your computer, open http://SERVER_IP:8080 or run the command below. Replace SERVER_IP with the reachable server address.
curl -i http://SERVER_IP:8080If you use the SSH tunnel, keep its session open and run this on your computer instead:
curl -i http://localhost:8080Expect HTTP 200 and the Nginx page.
If pulling fails, inspect registry access and image architecture. If the container exits, restore the default command and inspect logs. If access times out, check port mapping, firewall, server address, and tunnel. A domain route targets container port 80, not published port 8080.
Continue or clean up
Read application management. To remove the example, delete hello-web, wait for its containers to exit, then delete the empty demo group. Do not delete a group still used by other applications.
