Can I have root permissions on my Platform.sh projects ?
Root access is not available on Platform.sh. Platform.sh is a fully managed PaaS, which means most system-level configuration and package management is handled in an automated fashion by our team.
Most of each container is a read-only file system anyway, so even the root user would not be able to do much. The only writeable parts of the system are your file mounts, which you define in .platform.app.yaml and have full access to, and selected configuration files that are auto-generated on deploy based on your .platform.app.yaml file. That supports both repeatable deployments and tighter security.
