I’m running a single docker-compose.yml file that deploys multiple services;
- api_db
- api
- web_db
- php
- nginx
I also have all these services connected to a network defined below;
networks:
my-network:
name: my-network
On their own these containers work flawlessly. I can run docker and access the API from my host, as well as my web app, and the .env substitution works well for connecting web to web_db.
Where I’m having trouble is I want to get the IP/Host of the container api and substitute it inside my web app’s .env file so I can query the API from my web app. Currently when attempting this, my web app takes it literally as “api” and tries to send a request to “https://api:443/api/…”. The strange thing is, this is located in exactly the same .env file that I use to substitute web_db as the host, so I’m a bit confused as to why this is happening.
I’ve already confirmed with docker network inspect my-network that all containers are connected to my network correctly.
Not really sure what the issue is so hopefully someone can assist.
