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:

Code
 
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:

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

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

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

The output shows the instance URL and other details:

Code
 
[●] Deployed successfully!

 ├────────── uuid: bfb9d151-1604-452a-b2e0-f737486744df

 ├──── private ip: 172.16.3.1
 └────────── args: /usr/local/bin/wrapper.sh

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:

Code
 
kraft cloud inst list

Code
 
NAME             FQDN                                   STATE    STATUS              IMAGE                 MEMORY   ARGS                                     BOOT TIME
wordpress-fx5rb  cool-silence-h5c1es4z.fra0.kraft.host  running  since 2mins         wordpress@sha256:...  3.0 GiB  /usr/local/bin/wrapper.sh                1708.17 ms

When done, you can remove the instance:

Code
 
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.
