During the database initialization phase, I encountered two related issues:

1. The server/files/dbinit.sh script has "pgsql" strictly hardcoded (nxdbmgr init pgsql), which forces PostgreSQL initialization regardless of the DBDriver configured in /etc/netxmsd.conf or environment variables.

2. If we manually override /dbinit.sh on init container to initialize MariaDB (nxdbmgr init mariadb), the process fails because nxdbmgr looks for a specific dbinit_mariadb.sql file in a directory that does not exist in the Docker image.

Environment:

• NetXMS Version: 6.1.1 (Build 6.1-452-gc20a8a4247)
• Deployment: Docker (using official deployment-example/compose.yaml)
• Database: MariaDB 10.11

Steps to Reproduce:

1. Setup the deployment using the example compose.yml file, pointing /etc/netxmsd.conf to a MariaDB database (DBDriver = mariadb.ddr).
2. Override /dbinit.sh (entrypoint) on init container via bind mount to execute nxdbmgr init mariadb.
3. Start the init container.

Error Log (when using mariadb driver for init):

NetXMS Database Manager Version 6.1.1 Build 6.1-452-gc20a8a4247
Initializing database...
ERROR: Cannot load SQL command file /usr/share/netxms/sql/dbinit_mariadb.sql
Database initialization failed
Unable to determine database syntax

Note: I verified inside the container that the directory /usr/share/netxms does not exist on the NetXMS Server Docker image.

If I change the /etc/netxmsd.conf  to use mysql instead (nxdbmgr init mysql), the database initializes perfectly, even though I am using a MariaDB container:

NetXMS Database Manager Version 6.1.1 Build 6.1-452-gc20a8a4247

Database initialized successfully

Suggested Fixes:

1. Dynamic Driver Selection: Update /dbinit.sh to dynamically read the database driver from a Docker environment variable (e.g., NETXMS_DB_DRIVER) or directly from /etc/netxmsd.conf, falling back to pgsql only if nothing is set. Changing nxdbmgr init pgsql to simply nxdbmgr init allows the utility to dynamically deduce the driver from /etc/netxmsd.conf, as intended by the documentation.
2. Template Mapping: Either include the dbinit_mariadb.sql template in the image build process or alias the mariadb initialization argument to use the mysql SQL template internally, since the schema structure is identical.
