Deploy Wordpress

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

To run it, follow these steps:

1. Install the kraft CLI tool and a container runtime engine, e.g. Docker.

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

git clone https://github.com/kraftcloud/examples
cd examples/wordpress-all-in-one/

Make sure to log into Unikraft Cloud by setting your token and a metro close to you. We use fra0 (Frankfurt, 🇩🇪) in this guide:

# Set Unikraft Cloud access token
export UKC_TOKEN=token
# Set metro to Frankfurt, DE
export UKC_METRO=fra0

Note

A Wordpress instance on Unikraft Cloud requires 3GB to run. You may be required to request increasing the instance memory quota.

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

kraft cloud deploy -p 443:3000 -M 3072 .

The output shows the instance URL and other details:

[●] Deployed successfully!
 │
 ├────────── name: wordpress-fx5rb
 ├────────── uuid: bfb9d151-1604-452a-b2e0-f737486744df

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

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

At any point in time, you can list information about the instance:

kraft cloud inst list

NAME             FQDN                                   STATE    STATUS              IMAGE                 MEMORY   ARGS                                     BOOT TIME

When done, you can remove the instance:

kraft cloud instance remove wordpress-fx5rb

Customize Your Deployment

The current deployment uses the current stable version of Wordpress (6.5.5). It also uses hard-coded values for the database name, user name, passwords. You can update the Dockerfile with other names. Or expand the configuration to feature non-hard-coded values.

Wordpress modules can be deployed in the Wordpress instance without affecting the Unikraft Cloud build.

Other features, such as placing the databases files in a separate volume, can be considered.
