Hi

I have a problem with MariaDB (mysqld.sock)  
I have the next architecture:

1. Deployment for APP1
2. Deployment for MariaDB1
3. PV11 and PVC11 (/var/lib/mysql/), PV12 and PVC12 (/run/mysql/)
4. NFS1 server. Database and mysqld.sock save in NFS
5. Namespace1  
From deployment MariaDB1 I get files DB and mysqld.sock saved in NFS server and than mounted to deployment for app1. The APP1 works well.  
And I have exactly the same application 2 which does not work via the socket.  
When I connect to MySQL via mysqld.sock from pod APP1 I have a connection.  
But when I connect to MySQL via mysqld.sock from pod APP2 I have an error.

mysql -S /opt/mariadb-mysqld/mysqld.sock -u root -p ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/opt/mariadb-mysqld/mysqld.sock’ (111)
