We can see here in the ---outputs:--- section that Wordpress was allocated a public IP, in this case 35.193.210.254. It is exported with a stack output variable, frontendIp. We can use curl and grep to retrieve the <title> of the site the proxy points at.

$ curl -sL $(pulumi stack output frontendIp):80 | grep "<title>"
<title>User&#039;s Blog! &#8211; Just another WordPress site</title>

You can also navigate to the site in a web browser.

When you’re done, you can remove these resources with pulumi destroy:

pulumi destroy --skip-preview
