The second happens inside a running container, where the application is unable to write a file. To resolve these errors, it's essential to differentiate between them.\n\nDocker permission denied essentially means that the process attempting to write a file (or connect to the daemon) is not the owner of the file (or socket), and lacks the necessary group or other permissions. The kernel verifies these permissions based on the UID (user ID) and GID (group ID) of the process, not the user's name.",
