+Run Nginx on port 80 using Docker:
+
+```
+docker run -p 80:80 nginx:alpine
+```{{exec}}
+
+
+Or run it in background:
+
+```
+docker run -d -p 80:80 nginx:alpine
+```{{exec}}
+
+Now access Nginx using this link:
+
+[ACCESS NGINX]({{TRAFFIC_HOST1_80}})
+
+It's also possible to access ports using the top-right navigation in the terminal.
+Or we can display the link to that page:
+
+[ACCESS PORTS]({{TRAFFIC_SELECTOR}})
+
+It's also possible to generate access URLs in bash (foreground or background scripts) like this:
+
+```
+sed 's/PORT/80/g' /etc/killercoda/host
