 Other possible vulnerabilities such as file installation or container exits are escaped by limiting RAM memory, processing. Also, It removes privileges, network and disk writes (even within the container).
 In this way, a large part of the weaknesses are removed, especially in conjunction with a rate limiter (by IP, by Path, etc), load balancer, a queue system such that the server can run more than one container at a time and other security measures.
