Docker Container Containing Multiple Services-CodePudding

I am trying to build a container containing 3 applications, for example:

Grafana;
Node-RED;
NGINX.

So I will just need to expose one por, for example:

NGINX reverse proxy on port 3001/grafana redirects to grafana on port 3000 and; NGINX reverse proxy on port 3001/nodered redirects to nodered on port 1880.

Does it make any sense in your vision? Or this architecture is not feasible if compared to docker compose?

CodePudding user response：

If I understand correctly, your concern is about opening only one port publicly.

For this, you would be better off building 3 separate containers, each with their own service, and all in the same docker network. You could plug your services like you described within the virtual network instead of within the same container.

Why ? Because containers are specifically designed to hold the environment for a single application, in order to provide isolation and reduce compatibility issues, with all the network configuration done at a higher level, outside of the containers.

Having all your services inside the same container thwart these mentioned advantages of containerized applications. It's almost like you're not even using containers.
