Is it possible to increase max_connections of Mysql server bigger than 1000? Even if I set max_connections variable to 5000, it still allows only ±1000. Seems, it's on a side of OS (like file descriptor or something). Does it require to build a new repository with custom configuration for mysql ?

like this
docker run \

--name mysql \

--ulimit nofile=65536:65536 \

-e MYSQL_ROOT_PASSWORD=my-secret-pw \

-d mysql:latest

or like this
[mysqld]

max_connections = 5000

open_files_limit = 65535
