Wordpress

This guide shows you how to use Wordpress, a web content management system.

To run it, follow these steps:

1. Install the unikraft CLI. You need a BuildKit builder. The easiest way to get one is via Docker. Alternatively, you can also directly set up and use BuildKit, see the quick start.

2. Clone the examples repository and cd into the examples/wordpress-all-in-one/ directory:

   Code
   git clone https://github.com/unikraft-cloud/examples
   cd examples/wordpress-all-in-one/

Make sure to log into Unikraft Cloud and pick a metro close to you. This guide uses fra (Frankfurt, 🇩🇪):

Code
unikraft login

When done, invoke the following command to deploy this app on Unikraft Cloud:

Code
unikraft build . --output <my-org>/wordpress-all-in-one:latest
unikraft run --metro fra \
  -m 4G \
  -p 443:3000/tls+http \
  --scale-to-zero policy=on,cooldown-time=3000,stateful=true \
  --image <my-org>/wordpress-all-in-one:latest

The output shows the instance address and other details:

Code
metro:        fra
name:         wordpress-fx5rb
uuid:         bfb9d151-1604-452a-b2e0-f737486744df
state:        starting

In this case, the instance name is wordpress-fx5rb. They're different for each run.

Use a browser to access the install page of Wordpress. Fill out the form and complete the Wordpress install.

You can list information about the instance by running:

Code
unikraft instances list

Code

When done, you can remove the instance:

Code
unikraft instances delete wordpress-fx5rb
