Unfortunately it is not currently possible to install Docker on shared-hosting.
This includes installing Docker on Ecenica shared-web hosting, or installing Docker on Ecenica Managed VPS with cPanel/WHM installed.
The reason why you cannot install Docker is because Docker requires specific user privileges which would pose a security risk to you and other users hosted on the shared server.
Whilst it is not possible to install Docker on shared-hosting, it may be possible to deploy your application to your Ecenica shared-hosting using one of the following pre-installed features;
- SSH
- Git
- SFTP
- WP-CLI
- Composer
Please check your application and Ecenica plan for feature availability and compatibility.
