Common property configuration

Advanced configuration

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

Nacos + Grafana + Prometheus
