Install Community Edition on Magento Cloud server


Have anyone tried to install CE on Magento Cloud server? We’re developing a plugin which needs to be tested on both EE (works fine) and CE on the server. Many errors like missing class files (FrontController) or read-only file systems during cache cleaning happened during my deployment of CE on magento cloud. 


I’ve searched for all the possible solutions around the web but no hope. 


Could you help me with this please? Thank you.
