WordPress

This Helm chart deploys WordPress, the world’s most popular content management system, on Kubernetes. WordPress provides a flexible and user-friendly platform for creating websites, blogs, and web applications.

Prerequisites

• Kubernetes 1.19+
• Helm 3.0+
• kubectl configured to communicate with your cluster
• MySQL database (automatically installed as a dependency)

Dependencies

Before installing the chart, you need to download the required dependencies. Run the following command in the chart directory:

helm dependency build

This command will:

1. Read the dependencies from Chart.yaml
2. Download the required charts (MySQL and Service) from the specified repositories
3. Store them in the charts/ directory
4. Create or update the Chart.lock file with the exact versions

If you encounter any issues with the dependencies, you can try:

helm dependency update  # Updates dependencies to the latest versions

This chart requires the following dependencies to be installed:

MySQL

• Chart: mysql
• Version: 0.0.17
• Repository: https://helm.zop.dev
• Purpose: Provides the primary database for WordPress content and configuration

Service

• Chart: service
• Version: 0.0.17
• Repository: https://helm.zop.dev
• Purpose: Manages the WordPress application deployment and service configuration

To install these dependencies automatically, ensure the following in your values.yaml:

mysql:
  enabled: true
  # Additional MySQL configuration...

service:
  enabled: true
  # Additional service configuration...

The dependencies will be automatically installed when you deploy the WordPress chart. You can customize their configuration through the respective sections in your values.yaml file.

helm repo add zopdev https://helm.zop.dev
helm repo update
