 ## Set pre-installed services for user
 
 OpenPanel uses [docker images](https://dev.openpanel.com/images/) as the base for each hosting plan. Based on the docker image, different services can be set per plan/user. For examples, we provide 2 docker iamges, one that has nginx pre-installed and another that uses apache. By creating a custom docker image, you can set in that image what to be pre-installed when you create a new user, for exmaple, set mariadb instead of mysql or install php ioncube loader extension.
