the 3000 port is using by Grafana default.

How to solve this, thanks.

It seems like you have something already running on port 3000, you can specify another port for the container in the ports section of docker-compose.yml.

You can find more info about port bindings for docker compose in the official documentation: https://docs.docker.com/compose/networking/

I'll close this issue for now as it's not related to the container itself.

@ajeje93 Thanks. After I changed the port no to 3030:3030 from 3000:3000, the container of grafana-mongodb-docker_prod_1 is running.
But in Grafana dashboard, I cannot find the new Data Source, please help me again.

[ajeje93]

If you changed the port to 3030 you should access Grafana from that port. The container has both Grafana and the data source plugin inside.

I think you should change the port to something like 3030:3000 to map the port 3000 of the container (that is the Grafana port inside the container) to port 3030 of your PC, the access Grafana from http://localhost:3030.

@ajeje93 thanks. Got it!
the Grafana on http://localhost:3030.
and the data source on http://localhost:3000.
