• The database master-slave image has been removed, after the latest nacos/nacos-server:latest image. For specific reasons, refer to Removing the Master-Slave Image Configuration
• Since Nacos 1.3.1 version, the database storage has been upgraded to 8.0, and it is backward compatible
• If you use a custom database, you need to initialize the database script yourself for the first time.

If the above property configuration list does not meet your requirements, you can mount the custom.properties file into the /home/nacos/init.d/ directory of the container, where the spring properties can be configured, and the priority is higher than application.properties file

If you have a lot of custom configuration needs, It is highly recommended to mount application.properties in production environment.

For example:

docker-compose -f example/custom-application-config.yaml up -d
