Overview
WordPress Preview Environment is wordPress - the world's most widely used open-source CMS, powering blogs, business sites, and content-heavy publishing workflows through themes and plugins. This is a preview and staging profile of WordPress, meant as a disposable environment for testing changes and reviewing builds before they are promoted to production. Through DockerCP you can launch it on your own server with persistent volumes, a mapped domain, and automatic SSL. Sensible defaults for ports, volumes, and environment variables take you from template to running service in a few clicks.
How deployment works in DockerCP
This template gives DockerCP the deployment metadata needed to create a service, prepare runtime variables, map persistent storage, expose the internal port, and connect a public domain with SSL when required.
- Create or select a project where the service belongs.
- Review the Docker image, tag, default port, environment variables, and volume mappings.
- Deploy the service and check logs until the application is healthy.
- Attach a domain or subdomain when the application must be available publicly.
- Enable HTTPS and verify the final browser response.
Configuration
Environment variables
| Variable | Default / guidance |
|---|---|
APP_ENV |
production |
APP_PORT |
80 |
APP_URL |
https://example.com |
Persistent volumes
| Volume | Mount path |
|---|---|
| wordpress_preview_environment_data | /var/www/html |
Commands
DockerCP handles deployment from the panel, but understanding the equivalent Docker commands helps users debug services with more confidence.
docker pull wordpress:latest
docker ps --filter "name=wordpress-preview-environment"
docker logs --tail=100 wordpress-preview-environment
DNS and SSL checklist
| Step | Expected result |
|---|---|
| Add A or CNAME record | The domain points to the DockerCP server or configured target. |
| Attach domain to service | The service is reachable through the selected hostname. |
| Enable HTTPS | The certificate becomes active and redirect to HTTPS can be enabled. |

Troubleshoot
- Confirm the Docker image and tag exist.
- Confirm the selected internal port matches the application port.
- Confirm required variables such as database URL, app URL, and credentials are set.
- Check service logs after the first deployment.
- Verify DNS before requesting or renewing SSL certificates.
